PULMATRIX, INC.
Notes to Condensed Consolidated Financial Statements (Unaudited)
(in thousands, except share and per share data)
1. Organization
Pulmatrix, Inc. (the “Company”) was incorporated in 2013 as a Delaware corporation. The Company is a clinical-stage biopharmaceutical company focused on the development of a novel class of inhaled therapeutic products. The Company’s proprietary dry powder delivery platform, iSPERSE™, is engineered to deliver small, dense particles with highly efficient dispersibility and delivery to the airways, which can be used with an array of dry powder inhaler technologies and can be formulated with a variety of drug substances. The Company has developed a pipeline of iSPERSE™-based therapeutic candidates targeted at prevention and treatment of a range of central nervous system, respiratory and other diseases with important unmet medical needs.
2. Summary of Significant Accounting Policies and Recent Accounting Standards
Basis of Presentation
The condensed consolidated financial statements of the Company included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted from this report, as is permitted by such rules and regulations. Accordingly, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on March 28, 2024 (the “Annual Report”).
The financial information as of September 30, 2024, and for the three and nine months ended September 30, 2024 and 2023, is unaudited. In the opinion of management, all adjustments (including those which are normal and recurring) considered necessary for a fair presentation of the interim financial information have been included. The balance sheet data as of December 31, 2023 was derived from audited consolidated financial statements. The results of the Company’s operations for any interim periods are not necessarily indicative of the results that may be expected for any other interim period or for a full fiscal year.
Based on its current operating plan, the Company believes that its cash and cash equivalents as of September 30, 2024, will be adequate to fund its currently anticipated operating expenses for at least twelve months from the date these condensed consolidated financial statements are issued. The Company will need to secure additional funding in the future, from one or more equity or debt financings, collaborations, or other sources, in order to carry out all of the Company’s planned research and development activities and regulatory activities; commercialize product candidates; or conduct any substantial, additional development requirements requested by the FDA. Additional funding may not be available to the Company on acceptable terms, or at all. If the Company is unable to secure additional capital, it will be required to significantly decrease the amount of planned expenditures and may be required to cease operations. In addition, any disruption in the capital markets could make any financing more challenging, and there can be no assurance that Pulmatrix will be able to obtain such financing on commercially reasonable terms or at all. Curtailment of operations would cause significant delays in the Company’s efforts to develop and introduce its products to market, which is critical to the realization of its business plan and the future operations of the Company.
Use of Estimates
In preparing the condensed consolidated financial statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, as well as the reported amounts of expenses during the reporting period. Due to inherent uncertainty involved in making estimates, actual results may differ from these estimates. On an ongoing basis, the Company evaluates its estimates and assumptions. The most significant estimates and assumptions in the Company’s condensed consolidated financial statements have included, but are not limited to, estimates of future expected costs in order to derive and recognize revenue and estimates related to clinical trial accruals and upfront deposits.
| 5 |
Concentrations of Credit Risk
Cash is a financial instrument that potentially subjects the Company to concentrations of credit risk. For all periods presented, substantially all of the Company’s cash was deposited in accounts at a single financial institution that management believes is creditworthy, and the Company has not incurred any losses to date. The Company is exposed to credit risk in the event of default by this financial institution for amounts in excess of the Federal Deposit Insurance Corporation insured limits.
For
the three and nine months ended September 30, 2024, revenue from two customers accounted for
Summary of Significant Accounting Policies
The Company’s significant accounting policies are described in Note 2, Summary of Significant Accounting Policies and Recent Accounting Standards, in the Annual Report. During the nine months ended September 30, 2024, the Company did not make any changes to its significant accounting policies.
Recent Accounting Pronouncements
From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies that are adopted by the Company as of the specified effective date. The Company did not adopt any new accounting pronouncements during the nine months ended September 30, 2024 that had a material effect on its condensed consolidated financial statements.
In November 2023, the FASB issued Accounting Standard Update 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). The guidance in ASU 2023-07 expands prior reportable segment disclosure requirements by requiring entities to disclose significant segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and details of how the CODM uses financial reporting to assess their segment’s performance. The guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The standard is required to be applied retrospectively upon adoption. The Company is currently evaluating the impact that the adoption of ASU 2023-07 may have on its condensed consolidated financial statements.
In December 2023, the FASB issued Accounting Standard Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). The guidance in ASU 2023-09 improves the transparency of income tax disclosures by greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The standard becomes effective for the annual period beginning on January 1, 2025, with early adoption permitted. The Company is currently evaluating the impact that the adoption of ASU 2023-09 may have on its consolidated financial statements.
As of September 30, 2024, there are no other new, or existing recently issued, accounting pronouncements that are of significance, or potential significance, that impact the Company’s condensed consolidated financial statements.

6. Significant Agreements
Development and Commercialization Agreement with Cipla Technologies LLC (“Cipla”)
On April 15, 2019, the Company entered into a Development and Commercialization Agreement (the “Cipla Agreement”) with Cipla for the co-development and commercialization, on a worldwide exclusive basis, of PUR1900, the Company’s inhaled iSPERSE™ drug delivery system (the “Product”) enabled formulation of the antifungal drug itraconazole, which is only available as an oral drug, for the treatment of all pulmonary indications, including allergic bronchopulmonary aspergillosis (“ABPA”) in patients with asthma. The Company entered into an amendment to the Cipla Agreement on November 8, 2021 (the “Second Amendment”) and a subsequent amendment on January 6, 2024 (the “Third Amendment”). All references to the Cipla Agreement herein refer to the Cipla Agreement, as amended.
The
Company received a non-refundable upfront payment of $
Pursuant to the Third Amendment, the Company and Cipla agreed that, during the period commencing on January 6, 2024 and ending July 30, 2024 (the “Wind Down Period”), the Company would complete all Phase 2b activities, assign or license all patents to Cipla and their registration with the appropriate authorities in regions other than the United States, complete a physical and demonstrable technology transfer and secure all data from the Phase 2b study for inclusion in the safety database. The Company shared costs with Cipla during the Wind Down Period in the same proportions in effect with the Second Amendment discussed above, but subject to a maximum reimbursement amount by Cipla as approved by the joint steering committee. The Company completed all Phase 2b activities by the end of the Wind Down Period. The Company is in the process of settling certain final bills with its PUR1900 contractors, which together comprise an immaterial balance recorded within accounts payable as of September 30, 2024.
Accounting Treatment
The Company originally concluded that because both it and Cipla are active participants in the arrangement and are exposed to the significant risks and rewards of the collaboration, the Company’s collaboration with Cipla is within the scope of Accounting Standards Codification (“ASC”) 808, Collaborative Arrangements (“ASC 808”). The Company concluded that Cipla is a customer since they contracted with the Company to obtain research and development services and a license to the Assigned Assets, each of which is an output of the Company’s ordinary activities, in exchange for consideration. Therefore, the Company has applied the guidance in ASC 606, Revenue from Contracts with Customers (“ASC 606”) to account for the research and development services and a license within the contract. The Company determined that the research and development services and license to the Assigned Assets are considered highly interdependent and highly interrelated and therefore are considered a single combined performance obligation because Cipla cannot benefit from the license without the performance by the Company of the research and development services. Such research and development services are highly specialized and proprietary to the Company and therefore not available to Cipla from any other third party.
| 8 |
The
Company initially determined the total transaction price to be $
Revenue is recognized for the Cipla Agreement as the research and development services are provided using an input method, according to the ratio of costs incurred to the total costs expected to be incurred in the future to satisfy the Company’s obligations. In management’s judgment, this input method is the best measure of the transfer of control of the combined performance obligation. The amounts received that have not yet been recognized as revenue are recorded in deferred revenue on the Company’s consolidated balance sheets, with amounts expected to be recognized in the next 12 months recorded as current.
The
Company concluded that the Third Amendment is a contract modification that should be accounted for as part of the existing contract.
During the three and nine months ended September 30, 2024, the Company recognized $
Agreements with MannKind Corporation (“MannKind”)
On May 28, 2024, the Company executed certain agreements with MannKind and the Company’s landlord (collectively, the “MannKind Transaction”), all of which closed during July 2024. The agreements with MannKind included a Bill of Sale and Assignment Agreement (the “Bill of Sale”) with respect to the assignment of the Company’s rental facility at 36 Crosby Drive, Bedford, Massachusetts (the “Bedford Facility”) to MannKind along with the transfer of all leasehold improvements, laboratory equipment and other related personal property. In connection with the assignment of the Bedford Facility, the Company, MannKind and Cobalt Propco 2020, LLC (the “Landlord”) entered into an Amendment to Lease and Consent to Assignment of Lease (the “Lease Assignment Agreement”) pursuant to that certain Lease Agreement, dated as of January 7, 2022 (the “Lease Agreement”), by and between the Company and the Landlord. Pursuant to the Lease Assignment Agreement, MannKind assumed all of the Company’s obligations under the Lease Agreement, including all rent and other payments.
In connection with these transactions, the Company and MannKind entered into an Intellectual Property Cross License Agreement (the “Cross License Agreement”). Pursuant to the Cross License Agreement, the Company granted to MannKind (i) an exclusive license to develop, use, manufacture, market, offer and sell iSPERSE formulations of Clofazimine, (ii) an exclusive license to develop, use, manufacture, market, offer and sell formulations of iSPERSE with one more active pharmaceutical ingredients for the treatment of nontuberculous mycobacteria lung disease in humans, (iii) an exclusive license to develop, use, manufacture, market, offer and sell iSPERSE formulations of insulin, (iv) a non-exclusive license to develop, use, manufacture, market, offer and sell formulations of iSPERSE with one more active pharmaceutical ingredients for the treatment of endocrine disease in humans, and (v) a non-exclusive license to develop, use, manufacture, market, offer and sell formulations of iSPERSE with one more active pharmaceutical ingredients for the treatment of interstitial lung diseases (including IPF, PPF and other related lung diseases) in humans (collectively, the “Out-License”).
Additionally, pursuant to the Cross License Agreement, MannKind granted to the Company (i) the exclusive right to develop, use, manufacture, market, offer and sell its single-use disposable dry powder inhaler (including all modifications or improvement thereto made by or on behalf of the Company, the “Cricket Device”) for the inhaled delivery of dihydroergotamine in any formulation whatsoever, including the Company’s PUR3100 treatment of acute migraine and (ii) a non-exclusive license to develop, use, manufacture, market, offer and sell the Cricket Device for the inhaled delivery of one more active pharmaceutical ingredients formulated with iSPERSE for the treatment of neurological disease in humans (collectively, the “In-License”).
| 9 |
Additionally, pursuant to the Master Services Agreement, by and between the Company and MannKind, MannKind shall provide certain development services to the Company, including but not limited to, activities to develop a dry powder formulation of the active pharmaceutical ingredient that the Company provides to MannKind for oral inhalation using iSPERSE.
To maintain continuity of iSPERSE platform knowledge, MannKind hired certain members of the Company’s research and development staff in July 2024.
Accounting Treatment
The Company determined that the MannKind Transaction represents a combined agreement for accounting purposes, as the individual components have the same overall commercial objectives and the consideration under each component is dependent on the other components.
The consideration due to the Company in the MannKind Transaction consists solely of the non-cash consideration in the form of the In-License. The fair value of the non-cash consideration received should be allocated to the other components of the MannKind Transaction to determine the consideration received for the other components. The Company determined that the fair value of the In-License is immaterial given that adequate alternative inhaler devices are already available on the market (and indeed, the Company has already established use of another third-party inhalation device in their PUR3100 Phase 1 trial that performed well as a DHE delivery device as reported in a peer-reviewed publication), and considering optional purchases of Cricket Devices are at market prices. Accordingly, the consideration allocated to other components of the MannKind Transaction was immaterial.
During
the three months ended June 30, 2024, the Company accounted for the Lease Assignment Agreement upon execution as a lease modification
that reduced the lease term to the assignment date in July 2024. Accordingly, the Company remeasured its operating lease liability as
of the modification date to reflect the decrease in fixed lease payments, with the amount of the remeasurement, $
The
Company determined that its operating lease right-of-use asset and property and equipment subject to the Bill of Sale represented a disposal
group that became held for sale during the second quarter of 2024 and remained classified as held for sale as of June 30, 2024. The Company
recorded a full write-down of the disposal group’s carrying value as of June 30, 2024, in the amount of $
Concurrent with the closing of the MannKind Transaction, the Company terminated and MannKind hired the majority of the Company’s research and development employees, representing approximately two-thirds of the Company’s workforce at the time. The Company agreed to provide termination benefits to these employees, which has been fully paid as of September 30, 2024.

May 2021, the Company entered into an At-The-Market Sales Agreement (the “Sales Agreement”) with H.C. Wainwright and Co.,
LLC (“HCW”) to act as the Company’s sales agent with respect to the issuance and sale of up to $

11. Leases
New Corporate Headquarters
The Company has limited leasing activities as a lessee which are primarily related to its corporate headquarters, which were relocated during the third quarter of 2023 and again during the third quarter of 2024.
In June 2024, the Company entered into a short-term lease agreement for its new headquarters at 945 Concord Street, Framingham, Massachusetts. No lease liability or right-of-use asset has been recorded for this short-term lease, and the short-term lease cost associated with this lease is immaterial.
Previous Headquarters
On
May 28, 2024, as part of the MannKind Transaction (see further discussion in Note 6, Significant Agreements), the Company and
the Landlord executed the Lease Assignment Agreement to assign the Lease Agreement to MannKind in July 2024. The Company accounted for
the Lease Assignment Agreement as a lease modification that reduced the lease term to the assignment date in July 2024. Accordingly,
during the three months ended June 30, 2024, the Company remeasured its lease liability as of the modification date to reflect the decrease
in fixed lease payments, with the amount of the remeasurement, $

12. Income Taxes
The
Company had
Management of the Company evaluated the positive and negative evidence bearing upon the realizability of its deferred tax assets and determined that it is more likely than not that the Company will not recognize the benefits of the deferred tax assets. As a result, a full valuation allowance was recorded as of September 30, 2024 and December 31, 2023.
The Company applies ASC 740, Income Taxes, for the financial statement recognition, measurement, presentation, and disclosure of uncertain tax positions taken or expected to be taken in income tax returns. Unrecognized tax benefits represent tax positions for which reserves have been established. A full valuation allowance has been provided against the Company’s deferred tax assets, so that the effect of the unrecognized tax benefits is to reduce the gross amount of the deferred tax asset and the corresponding valuation allowance. The Company has no material uncertain tax positions as of September 30, 2024 and December 31, 2023.
Basic net loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per share is calculated by dividing the weighted-average number common shares outstanding during the period, after taking into consideration any potentially dilutive effects from outstanding stock options or warrants.
Basic and diluted net loss per share were the same for the three and nine months ended September 30, 2024 and 2023, as the effect of potentially dilutive securities would have been anti-dilutive.

Overview
Business
We are a clinical-stage biopharmaceutical company focused on the development of novel inhaled therapeutic products intended to prevent and treat respiratory and other diseases with important unmet medical needs using our patented iSPERSE™ technology. Our proprietary product pipeline includes treatments for central nervous system (“CNS”) disorders such as acute migraine and serious lung diseases such as Chronic Obstructive Pulmonary Disease (“COPD”) and allergic bronchopulmonary aspergillosis (“ABPA”). Our product candidates are based on our proprietary engineered dry powder delivery platform, iSPERSE™, which seeks to improve therapeutic delivery to the lungs by optimizing pharmacokinetics and reducing systemic side effects to improve patient outcomes.
We design and develop inhaled therapeutic products based on our proprietary dry powder delivery technology, iSPERSE™, which enables delivery of small or large molecule drugs to the lungs by inhalation for local or systemic applications. The iSPERSE™ powders are engineered to be small, dense particles with highly efficient dispersibility and delivery to airways. iSPERSE™ powders can be used with an array of dry powder inhaler technologies and can be formulated with a broad range of drug substances including small molecules and biologics. We believe the iSPERSE™ dry powder technology offers enhanced drug loading and delivery efficiency that outperforms traditional lactose-blend inhaled dry powder therapies.
Our goal is to develop breakthrough therapeutic products that are safe, convenient, and more effective than the existing therapeutic products for respiratory and other diseases where iSPERSE™ properties are advantageous.
Our current pipeline of clinical assets is aligned to this goal as we develop iSPERSE™-based therapeutic candidates which target the prevention and treatment of a range of diseases, including CNS disorders and pulmonary diseases. These therapeutic candidates include PUR3100 for the treatment of acute migraine, PUR1800 for the treatment of acute exacerbations of chronic obstructive pulmonary disease (“AECOPD”), and PUR1900 for the treatment of ABPA in patients with asthma and in patients with cystic fibrosis (“CF”). Each program is enabled by its unique iSPERSE™ formulation designed to achieve specific therapeutic objectives.
Contingent on securing additional funding, we intend to capitalize on our iSPERSE™ technology platform and our expertise in inhaled therapeutics to identify new product candidates for the prevention and treatment of diseases, including those with considerable unmet medical needs, and to build our product pipeline beyond our existing candidates. In order to advance clinical trials for our therapeutic candidates and leverage the iSPERSE™ platform to enable delivery of partnered compounds, we intend to form strategic alliances with third parties, including pharmaceutical and biotechnology companies or academic or private research institutes.
| 17 |
Contingent on securing additional funding, we expect to continue to incur substantial expenses and operating losses for at least the next several years based on our drug development plans and in connection with our ongoing activities, as we:
| ● | Pursue further clinical studies for PUR3100, an orally inhaled dihydroergotamine (“DHE”) including a Phase 2 clinical study for the treatment of acute migraine, contingent on securing financing or partnership arrangements. We received Food and Drug Administration (“FDA”) acceptance of our Investigational New Drug Application (“IND”) and a “study may proceed” letter in September 2023, positioning PUR3100 as Phase 2-ready for potential financing or partnership discussions. |
| We developed PUR3100, an iSPERSE™ formulation of DHE in 2020. We completed good laboratory practice (“GLP”) toxicology studies in 2021 and 2022. In 2022, we completed a Phase 1 study designed as a double-blinded trial to assess the safety, tolerability, and pharmacokinetics of three dose levels of single doses of inhaled PUR3100 with intravenous (“IV”) placebo, as compared to IV DHE (DHE mesylate injection) with inhaled placebo. |
On January 4, 2023, we announced the Phase 1 topline results, indicating that PUR3100 was safe and tolerated with fewer gastrointestinal side effects in all doses compared to IV DHE. PUR3100 showed a five-minute Tmax and Cmax within the targeted therapeutic range for all three doses tested. The Phase 1 study data was presented at the American Headache Society 65th Annual Meeting in June 2023. In May 2024, we announced a peer-reviewed publication of Phase 1 clinical results in the publication Headache: The Journal of Head and Face Pain.
In September 2023, we announced the FDA’s acceptance of an IND application for PUR3100 and receipt of a “study may proceed” letter for a Phase 2 study. The IND includes a Phase 2 clinical protocol where safety and preliminary efficacy of PUR3100 will be investigated in patients with acute migraine.
Based on the rapid systemic exposure in the therapeutic range and the improved side effect profile relative to IV dosing, we believe the PUR3100 formulation of DHE may differentiate from approved DHE products or those in development. If effectiveness is demonstrated, PUR3100 may offer the convenience of being self-administered with a pharmacokinetic profile that may potentially provide rapid onset of action. | ||
| ● | Pursue partnership or other alternatives to monetize or advance PUR1800, focusing on the development of an orally inhaled kinase inhibitor for treatment of AECOPD. | |
| We completed preclinical safety studies for PUR1800, our iSPERSE™ formulation of RV1162, in 2018 and advanced our formulation and process development efforts to support clinical testing in stable moderate-severe COPD patients. We completed a Phase 1b safety, tolerability, and pharmacokinetics clinical study of PUR1800 for subjects with stable moderate-severe COPD and received topline data from the Phase 1b clinical study in the first quarter of 2022. We analyzed data from the completed Phase 1b clinical study of PUR1800 for AECOPD and presented study results at the American Academy of Allergy, Asthma & Immunology (AAAAI) conference in the first quarter of 2023. The results indicated PUR1800 was safe and well tolerated with no observed safety signals. The topline data, along with the results from chronic toxicology studies, support the continued development of PUR1800 for the treatment of AECOPD and other inflammatory respiratory diseases. | ||
| ● | Capitalize on our proprietary iSPERSE™ technology and our expertise in inhaled therapeutics and particle engineering to identify new product candidates for prevention and treatment of diseases, including those with important unmet medical needs. | |
| To add additional inhaled therapeutics to our development pipeline and facilitate additional collaborations, we are leveraging our iSPERSE™ technology and our expertise in inhaled therapeutics and particle engineering to identify potential product candidates. | ||
| ● | Invest in protecting and expanding our intellectual property portfolio and file for additional patents to strengthen our intellectual property rights. |
| 18 |
| The status of our patent portfolio changes frequently in the ordinary course of patent prosecution. As of September 30, 2024, our patent portfolio related to iSPERSE™ included approximately 147 granted patents, 18 of which are granted US patents, with expiration dates from 2024 to 2037, and approximately 51 additional pending patent applications in the US and other jurisdictions. Our in-licensed portfolio related to kinase inhibitors included approximately 280 granted patents, 33 of which are granted US patents, with expiration dates from 2029 to 2035, and approximately 18 additional pending patent applications in the US and other jurisdictions. We have national phase applications pending in Australia, Brazil, Canada, China, Europe, Israel, India, Japan, Korea, Mexico, New Zealand, Russia, and the United States that cover certain formulations and methods of use relevant to our PUR3100 program. |
| ● | Seek partnerships and license agreements to support the product development and commercialization of our product candidates. | |
| In order to advance our clinical programs, we may seek partners or licensees in areas of pharmaceutical and clinical development. |
| ● | Position the Company to be able to consider strategic alternatives. | |
| Continue our cost saving measures which have included the wind down of the Phase 2b study for PUR1900 and the assignment of our long-term lease of our Bedford facility pursuant to those certain agreements by and between us, MannKind Corporation (“MannKind”) and Cobalt Propco 2020, LLC (the “MannKind Transaction”) to conserve our cash resources as we consider strategic alternatives for the Company. |
Therapeutic Candidates
PUR3100
In 2020, we developed PUR3100, the iSPERSE™ formulation of DHE, for the treatment of acute migraine. Currently DHE is only available as subcutaneous, intravenous infusion or intranasal delivery. If approved for commercialization, PUR3100 has the opportunity to be the first orally inhaled DHE treatment for acute migraine and be an alternative to other acute therapies. Given the oral inhaled route of delivery, PUR3100 is anticipated to provide relief from the rapid onset of migraine symptoms and provide a favorable tolerability profile.
A total of three 14-day GLP toxicology studies have been completed with PUR3100 to support single-dose clinical studies. We are planning to conduct a chronic toxicology study to support long-term dosing. Based on discussions with the FDA, this would complete the non-clinical requirements to support a new drug application (“NDA”).
Our interactions with the FDA have indicated that, in addition to the planned Phase 2 and Phase 3 studies, long-term safety should be assessed in a minimum of one hundred patients for six months of dosing and fifty patients for twelve months of dosing. The FDA also confirmed that it will be necessary to perform a safety study administering PUR3100 to otherwise healthy patients with asthma before an NDA is submitted.
On September 26, 2022, we announced the completion of patient dosing in a Phase 1 clinical study, performed in Australia. The study design was a double-dummy, double-blinded trial to assess the safety, tolerability, and pharmacokinetics of three dose levels of single doses of inhaled PUR3100 with IV placebo, as compared to IV DHE (DHE mesylate injection) with inhaled placebo. This study may also provide preliminary comparative bioavailability data to support the use of the 505(b)(2) pathway for marketing authorization. Twenty-six healthy subjects were enrolled and each of the four groups contained at least six subjects.
On January 4, 2023, we announced topline results. We presented the Phase 1 study data at the American Headache Society 65th Annual Meeting in June 2023. The study showed that PUR3100 achieved peak exposures in the targeted therapeutic range and time to maximum concentration occurred at five minutes after dosing at all dosing levels. The PUR3100 dose groups also showed a lower incidence of nausea and no vomiting compared to observations of nausea and vomiting in the IV administered DHE dose group.
| 19 |
Based on the rapid systemic exposure in the therapeutic range and the improved side effect profile relative to IV dosing, we believe the PUR3100 formulation of DHE may differentiate from approved DHE products or those known to be in development. If effectiveness is demonstrated, PUR3100 may offer the convenience of being self-administered with a pharmacokinetic profile that may potentially provide rapid onset of action.
In September 2023, we announced that the FDA accepted the PUR3100 IND and the receipt of a “study may proceed” letter for the clinical study: “A Phase 2, Multicenter, Randomized, Double-Blind, Placebo-Controlled, Single Event Study to Evaluate the Safety, Tolerability, and Efficacy of PUR3100 (Dihydroergotamine Mesylate Inhalation Powder) in the Acute Treatment of Migraine”. We anticipate that this Phase 2 clinical study will initiate once financing or partnership arrangements have been made.
On May 15, 2024, we announced publication of, “Safety, tolerability, and pharmacokinetics of a single orally inhaled dose of PUR3100, a dry powder formulation of dihydroergotamine versus intravenous dihydroergotamine: A Phase 1 randomized, double-blind study in healthy adults” in the peer-reviewed publication Headache: The Journal of Head and Face Pain.
We believe that in this trial, PUR3100 demonstrated the potential for rapid pain relief and improved DHE tolerability versus IV DHE. With a Tmax of 5 minutes and a Cmax in the therapeutic window for all doses tested, we believe that PUR3100 has the potential to address an unmet need for acute migraine sufferers and we are pursuing different options to advance PUR3100 into a Phase 2 clinical trial to further investigate its promising profile in treating acute migraine.
The completed Phase 1 study demonstrated optimal pharmacokinetics and improved tolerability of PUR3100 compared to IV DHE. The Phase 1 trial was a randomized, double-dummy, double-blinded design to assesses the safety, tolerability, and pharmacokinetics (PK) of three dose groups treated with inhaled PUR3100 with intravenous (IV) placebo, compared to a single dose of IV DHE (DHE mesylate injection) with inhaled placebo in healthy volunteers. All doses of PUR3100 were generally well tolerated with a lower incidence of nausea (21% vs. 86%), vomiting (0% vs. 29%), and headache (16% vs. 57%) compared to IV DHE. The PK profile of PUR3100 versus IV DHE was characterized by a similar mean time to Cmax (5 vs. 5.5 min), with reduced AUC0–2h (1120–4320 vs. 6340), and a lower Cmax (3620–14,400 vs. 45,000). All doses of PUR3100 were associated with mean Cmax above the minimum level required to achieve efficacy (1000 pg/mL).
Over 39 million patients suffer from migraine in the United States and there is currently no orally inhaled DHE treatment option for patients. PUR3100 is our orally inhaled therapeutic candidate formulation of DHE engineered with iSPERSE™ for the treatment of acute migraine. Pulmatrix is currently looking at opportunities to finance or partner PUR3100 to initiate a potential Phase 2 clinical study.
PUR1800
Reduced responsiveness to corticosteroids represents an important barrier to effective treatment of COPD and AECOPD and provides a clear rationale to seek novel medicines to treat these respiratory diseases. In addition, current treatments generally fail to treat the underlying source of the AECOPD, in particular when a viral or bacterial infection is the cause, which occurs in approximately 80% of exacerbations. RV1162, the active ingredient of PUR1800, is a novel, potent anti-inflammatory that inhibits the phosphorylation of a narrow spectrum of kinases. In pre-clinical studies, RV1162 demonstrated direct anti-inflammatory activity in a model of viral induced respiratory inflammation. RV1162 also demonstrated a reduction in corticosteroid-resistant inflammatory responses in a model of cigarette smoke induced inflammation. These findings suggested that RV1162 has the potential to deliver effective anti-inflammatory outcomes in corticosteroid-resistant patients while also reducing the underlying source of inflammation in an exacerbation, such as a viral and/or bacterial respiratory infection.
Clinical studies conducted by RespiVert/Janssen with RV1162 formulated as a lactose blend for inhalation demonstrated that the molecule was well tolerated for up to 14 days of dosing in patients with COPD. Analysis of sputum collected from patients with COPD treated with RV1162 showed reduced levels of p38 phosphorylation in sputum cells and decreases in the number of neutrophils recovered in sputum after 12 days of dosing. These findings suggest that inhalation of RV1162 may confer anti-inflammatory benefits after a short dosing regimen. Long-term toxicology studies with RV1162 as a lactose blend suggested that this formulation was not suitable for chronic dosing.
| 20 |
Based upon the clinical results generated by RespiVert/Janssen for RV1162 and the anticipated benefits of an iSPERSE™ formulation of RV1162, we entered into a License, Development and Commercialization Agreement with RespiVert Ltd. (“RespiVert”), a wholly owned subsidiary of Janssen Biotech, Inc. on June 9, 2017. RespiVert granted us an exclusive, royalty-bearing license in a portfolio of narrow spectrum kinase inhibitor compounds (“NSKI”). We subsequently formulated RV1162 into PUR1800 for development as a potential therapy for AECOPD.
We completed a Phase 1b safety, tolerability, and pharmacokinetics of PUR1800 for patients with stable moderate-severe COPD. Topline data was delivered in the first quarter of 2022 and presented at the American Academy of Allergy, Asthma and Immunology conference in the first quarter of 2023.
The clinical study, performed at the Medicines Evaluation Unit in Manchester, UK, was a randomized, three-way crossover double-blind study with 14 days of daily dosing, which included placebo and one of two doses of PUR1800, and included a 28-day follow-up period after each treatment period. A total of 18 adults with stable COPD were enrolled. Safety and tolerability, as well as systemic pharmacokinetics (“PK”) were evaluated.
PUR1800 was well tolerated and there were no observed safety signals. The PK data indicate that PUR1800 results in low and consistent systemic exposure when administered via oral inhalation. The topline data, along with the results from chronic toxicology studies, support the continued development of PUR1800 for the treatment of AECOPD and other inflammatory respiratory diseases. These data will inform the design of a potential Phase 2 study in the treatment of AECOPD.
PUR1900
PUR1900 is our iSPERSE™ inhaled formulation of itraconazole, an antifungal drug commercially available as an oral drug. We developed PUR1900 for the prevention and treatment of fungal infections and allergic/hypersensitivity reactions to fungus in patients with severe lung disease, including those with asthma and CF.
On April 15, 2019, we entered into the Cipla Agreement with Cipla for the co-development and commercialization, on a worldwide, except for the Cipla Territory defined below, exclusive basis, of PUR1900, our inhaled iSPERSE™ enabled formulation of the antifungal drug itraconazole, which is only available as an oral drug, for the treatment of all pulmonary indications, including ABPA in patients with asthma. We entered into the Second Amendment to the Cipla Agreement on November 8, 2021 and the Third Amendment on January 6, 2024. All references to the Cipla Agreement herein refer to the Cipla Agreement, as amended. The Cipla Agreement will remain in effect in perpetuity, unless otherwise earlier terminated in accordance with its terms.
Pursuant to the Third Amendment, the definition of the “Cipla Territory”, has been expanded to include all markets other than the United States.
Pursuant to the Third Amendment, all development and commercialization activities with respect to the Product in all markets other than the United States (the “Cipla Territory”) will be conducted exclusively by Cipla at Cipla’s sole cost and expense, and Cipla shall be entitled to all profits from the sale of the Product in the Cipla Territory, except that we will receive 2% royalties on any potential future net sales by Cipla outside the United States.
Pursuant to the Third Amendment, we and Cipla stopped patient enrollment for the ongoing Phase 2b clinical study. We agreed that during the period commencing on January 6, 2024 and ending July 30, 2024 (the “Wind Down Period”), we would complete all Phase 2b activities, assign or license all patents to Cipla and their registration with the appropriate authorities in the Cipla Territory, complete a physical and demonstrable technology transfer and secure all data from the Phase 2b study for inclusion in the safety database for the Cipla Territory.
For the duration of the Wind Down Period, we and Cipla were each responsible for 60% and 40%, respectively, of our Direct Costs. We shared all other development costs with Cipla that are not Direct Costs, such as the cost of clinical research organizations, manufacturing costs and other third-party costs, on a 50/50 basis. Reimbursements from Cipla to us for these costs were subject to a maximum reimbursement amount as approved by the joint steering committee.
| 21 |
We completed all Phase 2b wind down activities within the third quarter of 2024. As such, we no longer bear further financial responsibility for the commercialization and development with respect to the Product in the Cipla Territory, with such commercialization and development expenses of the Product in the Cipla Territory to be borne at Cipla’s sole cost and expense after January 6, 2024. We will receive 2% royalties on any potential future net sales by Cipla outside the United States. Within the United States, we and Cipla will seek to monetize PUR1900, our inhaled iSPERSE™ formulation of the antifungal drug itraconazole for indications where an orally inhaled antifungal may provide a therapeutic benefit or fulfill an unmet medical need.
Financial Overview
Revenues
To date, we have not generated any product sales. The revenues for the three and nine months ended September 30, 2024 and 2023 were primarily generated from the Cipla Agreement as related to our PUR1900 program, for which wind down activities have been completed.
For more discussion on the Cipla Agreement, please see Note 6, Significant Agreements, to our condensed consolidated financial statements included in this Quarterly Report on Form 10-Q.
Research and Development Expenses
Research and development expenses consist primarily of costs incurred for the research and development of our preclinical and clinical candidates, and include:
| ● | employee-related expenses, including salaries, benefits and stock-based compensation expense; | |
| ● | expenses incurred under agreements with contract research organizations (“CROs”) or contract manufacturing organizations (“CMOs”), and consultants that conduct our clinical trials and preclinical activities; | |
| ● | the cost of acquiring, developing and manufacturing clinical trial materials and lab supplies; |
| ● | facility, depreciation and other expenses, which include direct and allocated expenses for rent, maintenance of our facility, insurance and other supplies; |
| ● | costs associated with preclinical activities and clinical regulatory operations; and | |
| ● | consulting and professional fees associated with research and development activities |
We expense research and development costs to operations as incurred. We recognize costs for certain development activities, such as clinical trials, based on an evaluation of the progress to completion of specific tasks using data such as patient enrollment, clinical site activations or information provided to us by our vendors.
Research and development activities are central to our business model. We have utilized a combination of internal and external efforts to advance product development from early-stage work to clinical trial manufacturing and clinical trial support. External efforts have included work with consultants and substantial work at CROs and CMOs. We have historically supported an internal research and development team and facility for our pipeline and other potential development programs, however following the closing of the MannKind Transaction in the third quarter of 2024, in which the majority of our research and development employees were terminated and our facility lease was assigned to MannKind, we expect to utilize external resources for further development.
| 22 |
To continue development of existing programs or opportunities identified for iSPERSE™ in any new indications, we will need to secure additional funding and anticipate additional development costs would be incurred. Because of the numerous risks and uncertainties associated with product development, however, we cannot determine with certainty the duration and completion costs of these or other current or future preclinical studies and clinical trials. The duration, costs and timing of our future clinical trials and development of our product candidates will depend on a variety of factors, including the selected development path and uncertainties associated with clinical and preclinical studies, clinical trial enrollment rates and changing government regulation. In addition, the probability of success for each product candidate will depend on numerous factors, including competition, manufacturing capability and commercial viability.
General and Administrative Expenses
General and administrative expenses consist principally of salaries, benefits and related costs such as stock-based compensation for personnel and consultants in executive, finance, business development, corporate communications and human resource functions, facility costs not otherwise included in research and development expenses, patent filing fees and legal fees. Other general and administrative expenses include travel expenses, expenses related to being a publicly traded company and professional fees for consulting, auditing and tax services.
Following the closing of the MannKind Transaction in the third quarter of 2024, we anticipate that our general and administrative expenses will decrease in the future as they relate to audit, legal, regulatory, and tax-related services associated with maintaining compliance with exchange listing and SEC requirements, director and officer liability insurance, investor relations costs and other costs associated with being a public company.
Critical Accounting Estimates
This management’s discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of these condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in our condensed consolidated financial statements. We base our estimates on historical experience, known trends and events, and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Actual results may differ from these estimates under different assumptions or conditions.
There were no changes to our critical accounting estimates during the nine months ended September 30, 2024 as compared to those described in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report. It is important that the discussion of our operating results that follow be read in conjunction with the critical accounting estimates disclosed in our Annual Report.

Results of Operations
Comparison of the Three Months Ended September 30, 2024 and 2023
The following table sets forth our results of operations for each of the periods set forth below (in thousands):

Revenues — Revenues were $0.4 million for the three months ended September 30, 2024, as compared to $1.8 million for the three months ended September 30, 2023, a decrease of $1.4 million. The decrease is primarily related to the wind down of the PUR1900 Phase 2b clinical trial, for which we incurred fewer expenses eligible for reimbursement under the Cipla Agreement as compared to the corresponding period in the previous year.
Research and development expenses — Research and development expenses were $0.8 million for the three months ended September 30, 2024, as compared to $4.0 million for the three months ended September 30, 2023, a decrease of approximately $3.2 million. The decrease was primarily due to $1.7 million less employment and other operating cost following the MannKind Transaction, $1.2 million less cost incurred on the PUR1900 program, for which the winding down of the Phase 2b clinical trial was completed during the three months ended September 30, 2024, and $0.3 million less cost incurred on the PUR3100 program.
General and administrative expenses — General and administrative expenses were $2.2 million for the three months ended September 30, 2024, as compared to $1.7 million for the three months ended September 30, 2023, an increase of approximately $0.5 million. The increase was primarily due to $0.6 million of increased employment costs associated with employee terminations, partially offset by $0.1 million of decreased operating costs.

Comparison of the Nine Months Ended September 30, 2024 and 2023
The following table sets forth our results of operations for each of the periods set forth below (in thousands):

Revenues — Revenues were $7.8 million for the nine months ended September 30, 2024, as compared to $5.1 million for the nine months ended September 30, 2023, an increase of $2.7 million. The increase is primarily related to a contract modification of the Cipla Agreement which resulted in a cumulative catch-up adjustment recorded during the three months ended March 31, 2024. The amount of the cumulative catch-up had been included in deferred revenue at the beginning of the period. This increase was partially offset by the Company incurring fewer expenses eligible for reimbursement under the Cipla Agreement as compared to the corresponding period in the previous year.
Research and development expenses — Research and development expenses were $7.2 million for the nine months ended September 30, 2024, as compared to $12.0 million for the nine months ended September 30, 2023, a decrease of approximately $4.8 million. The decrease was primarily due to $2.0 million less cost incurred on the PUR1900 program during the winding down of the Phase 2b clinical trial, $2.0 million less employment and other operating cost following the MannKind Transaction and $0.8 million less cost related to the PUR3100 and PUR1800 programs.
General and administrative expenses — General and administrative expenses were $5.8 million for the nine months ended September 30, 2024, as compared to $5.6 million for the nine months ended September 30, 2023, an increase of approximately $0.2 million. The increase was primarily due to $0.4 million of increased employment costs associated with employee terminations, partially offset by $0.2 million of decreased other operating costs.
Loss on MannKind Transaction — Loss on MannKind Transaction was $2.6 million on certain assets held for sale as of June 30, 2024 and disposed of during the three months ended September 30, 2024, in connection with the MannKind Transaction, as compared with no such loss for the nine months ended September 30, 2023.
Liquidity and Capital Resources
Through September 30, 2024, we incurred an accumulated deficit of $295.2 million, primarily as a result of expenses incurred through a combination of research and development activities related to our various product candidates and general and administrative expenses supporting those activities. We have financed our operations since inception primarily through the sale of preferred and common stock, the issuance of convertible promissory notes, term loans, and collaboration and license agreements. Our total cash and cash equivalents balance as of September 30, 2024 was $10.8 million.
We anticipate that we will continue to incur losses in the foreseeable future due to development costs associated with our iSPERSE™ pipeline programs, contingent on obtaining financing or partnership to continue such development. We may raise capital through a combination of equity offerings, debt financings, other third-party funding and other collaborations and strategic alliances. We are currently exploring financing or partnership arrangements to develop and initiate a potential Phase 2 clinical study for PUR3100.
| 25 |
We expect that our existing cash and cash equivalents as of September 30, 2024 will enable us to fund our corporate operating expenses for at least the next 12 months following the date of this Quarterly Report on Form 10-Q. We have based our projections of operating capital requirements on assumptions that may prove to be incorrect, and we may use all of our available capital resources sooner than we expect. Because of the numerous risks and uncertainties associated with research, development, achievement of contingent milestones and commercialization of pharmaceutical products, we are unable to estimate the exact amount of our operating capital requirements.
We have no material off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.
The following table sets forth the major sources and uses of cash for each of the periods set forth below (in thousands):
| Nine Months Ended September 30, | ||||||||
| 2024 | 2023 | |||||||
| Net cash used in operating activities | $ | (9,455 | ) | $ | (13,974 | ) | ||

| Net cash provided by financing activities | - | 53 | ||||||
| Net decrease in cash, cash equivalents, and restricted cash | $ | (9,853 | ) | $ | (14,292 | ) | ||
Net cash used in operating activities
Net cash used in operating activities for the nine months ended September 30, 2024 was $9.5 million, which was primarily the result of $7.6 million of net loss and $5.4 million in cash outflows associated with changes in operating assets and liabilities, partially offset by $3.6 million of net non-cash adjustments.
Net cash used in operating activities for the nine months ended September 30, 2023 was $14.0 million, which was primarily the result of a net loss of $12.0 million and $4.0 million in cash outflows associated with changes in operating assets and liabilities, partially offset by $2.0 million of net non-cash adjustments.
Net cash used in investing activities
Net cash used in investing activities was $0.4 million for both the nine months ended September 30, 2024 and 2023, which was due to purchases of property and equipment.
Net cash provided by financing activities
No cash was provided by financing activities for the nine months ended September 30, 2024. Net cash provided by financing activities for the nine months ended September 30, 2023 resulted from proceeds from the issuance of common stock, net of issuance costs.
Financings
In May 2021, we entered into the Sales Agreement with HCW to act as our sales agent with respect to the issuance and sale of up to $20,000,000 of our shares of common stock, from time to time in an ATM Offering. Upon filing of the Annual Report, we continued to be subject to General Instruction I.B.6 of Form S-3, pursuant to which in no event will we sell our common stock in a registered primary offering using Form S-3 with a value exceeding more than one-third of our public float in any 12 calendar month period so long as our public float remains below $75,000,000. Therefore, the amount we may be able to raise using the ATM Offering will be significantly less than $20,000,000, until such time as our public float held by non-affiliates exceeds $75,000,000.
| 26 |
Sales of common stock under the Sales Agreement are made pursuant to an effective shelf registration statement on Form S-3, which was filed with the SEC on May 17, 2024, and subsequently declared effective on May 30, 2024 (File No. 333-279491), and a related prospectus. HCW acts as our sales agent on a commercially reasonable efforts basis, consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of Nasdaq. If expressly authorized by us, HCW may also sell our common stock in privately negotiated transactions. There is no specific date on which the ATM Offering will end, there are no minimum sale requirements and there are no arrangements to place any of the proceeds of the ATM Offering in an escrow, trust or similar account. HCW is entitled to compensation at a fixed commission rate of 3.0% of the gross proceeds from the sale of our common stock pursuant to the Sales Agreement.
During the nine months ended September 30, 2024, no shares of our common stock were sold under the Sales Agreement.
Known Trends, Events and Uncertainties
In May 2023, the World Health Organization determined that COVID-19 no longer fit the definition of a public health emergency and the U.S. government announced its plan to let the declaration of a public health emergency associated with COVID-19 expire on May 11, 2023. In addition, ongoing geopolitical conflicts, including between Russia and Ukraine and between Israel and Hamas, and related sanctions and countermeasures, are difficult to predict, and could adversely impact geopolitical and macroeconomic conditions, the global economy, and contribute to increased market volatility, which may in turn adversely affect our business and operations. We may not be able to raise sufficient additional capital and may tailor our drug candidate development program based on the amount of funding we are able to raise in the future. Nevertheless, there is no assurance that these initiatives will be successful.
Other than as discussed above and elsewhere in this report, we are not aware of any trends, events or uncertainties that are likely to have a material effect on our financial condition.
Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Not applicable.
Item 4. Controls and Procedures.
Disclosure Controls and Procedures
Our Principal Executive Officer and Principal Financial Officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this Quarterly Report on Form 10-Q, have concluded that, based on such evaluation, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and is accumulated and communicated to our management, including our Principal Executive Officer and Principal Financial Officer as appropriate to allow timely decisions regarding required disclosure.
In designing and evaluating our disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and our management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
Changes in Internal Controls over Financial Reporting
There were no changes in our internal control over financial reporting that occurred during the quarter ended September 30, 2024 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
| 27 |
PART II—OTHER INFORMATION
Item 1. Legal Proceedings.
From time to time, we may be involved in litigation that arises through the normal course of business. As of the date of this filing, we are not aware of any material legal proceedings to which we or any of our subsidiaries is a party or to which any of our property is subject, nor are we aware of any such threatened or pending litigation or any such proceedings known to be contemplated by governmental authorities.
We are not aware of any material proceedings in which any of our directors, officers, or affiliates or any registered or beneficial stockholder of more than 5% of our common stock, or any associate of any of the foregoing, is a party adverse to or has a material interest adverse to, us or any of our subsidiaries.
Item 1A. Risk Factors.
Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described in Part I, Item 1A under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2023, in addition to the other information included in this Quarterly Report on Form 10-Q before making an investment decision regarding our common stock. If any of these risks actually occur, our business, financial condition, or operating results would likely suffer, possibly materially, the trading price of our common stock could decline, and you could lose part or all of your investment.

| Summary of Significant Accounting Policies and Recent Accounting Standards | 2. Summary of Significant Accounting Policies and Recent Accounting Standards
Basis of Presentation
The condensed consolidated financial statements of the Company included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted from this report, as is permitted by such rules and regulations. Accordingly, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on March 28, 2024 (the “Annual Report”).
The financial information as of September 30, 2024, and for the three and nine months ended September 30, 2024 and 2023, is unaudited. In the opinion of management, all adjustments (including those which are normal and recurring) considered necessary for a fair presentation of the interim financial information have been included. The balance sheet data as of December 31, 2023 was derived from audited consolidated financial statements. The results of the Company’s operations for any interim periods are not necessarily indicative of the results that may be expected for any other interim period or for a full fiscal year.
Based on its current operating plan, the Company believes that its cash and cash equivalents as of September 30, 2024, will be adequate to fund its currently anticipated operating expenses for at least twelve months from the date these condensed consolidated financial statements are issued. The Company will need to secure additional funding in the future, from one or more equity or debt financings, collaborations, or other sources, in order to carry out all of the Company’s planned research and development activities and regulatory activities; commercialize product candidates; or conduct any substantial, additional development requirements requested by the FDA. Additional funding may not be available to the Company on acceptable terms, or at all. If the Company is unable to secure additional capital, it will be required to significantly decrease the amount of planned expenditures and may be required to cease operations. In addition, any disruption in the capital markets could make any financing more challenging, and there can be no assurance that Pulmatrix will be able to obtain such financing on commercially reasonable terms or at all. Curtailment of operations would cause significant delays in the Company’s efforts to develop and introduce its products to market, which is critical to the realization of its business plan and the future operations of the Company.
Use of Estimates
In preparing the condensed consolidated financial statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, as well as the reported amounts of expenses during the reporting period. Due to inherent uncertainty involved in making estimates, actual results may differ from these estimates. On an ongoing basis, the Company evaluates its estimates and assumptions. The most significant estimates and assumptions in the Company’s condensed consolidated financial statements have included, but are not limited to, estimates of future expected costs in order to derive and recognize revenue and estimates related to clinical trial accruals and upfront deposits.
Concentrations of Credit Risk
Cash is a financial instrument that potentially subjects the Company to concentrations of credit risk. For all periods presented, substantially all of the Company’s cash was deposited in accounts at a single financial institution that management believes is creditworthy, and the Company has not incurred any losses to date. The Company is exposed to credit risk in the event of default by this financial institution for amounts in excess of the Federal Deposit Insurance Corporation insured limits.
For the three and nine months ended September 30, 2024, revenue from two customers accounted for 100% of revenue recognized in the accompanying condensed consolidated financial statements. For the three and nine months ended September 30, 2023, revenue from one customer accounted for 100% of revenue recognized in the accompanying condensed consolidated financial statements. As of September 30, 2024 and December 31, 2023, one customer accounted for 100% of accounts receivable.
Summary of Significant Accounting Policies
The Company’s significant accounting policies are described in Note 2, Summary of Significant Accounting Policies and Recent Accounting Standards, in the Annual Report. During the nine months ended September 30, 2024, the Company did not make any changes to its significant accounting policies.
Recent Accounting Pronouncements
From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies that are adopted by the Company as of the specified effective date. The Company did not adopt any new accounting pronouncements during the nine months ended September 30, 2024 that had a material effect on its condensed consolidated financial statements.
In November 2023, the FASB issued Accounting Standard Update 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). The guidance in ASU 2023-07 expands prior reportable segment disclosure requirements by requiring entities to disclose significant segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and details of how the CODM uses financial reporting to assess their segment’s performance. The guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The standard is required to be applied retrospectively upon adoption. The Company is currently evaluating the impact that the adoption of ASU 2023-07 may have on its condensed consolidated financial statements.
In December 2023, the FASB issued Accounting Standard Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). The guidance in ASU 2023-09 improves the transparency of income tax disclosures by greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The standard becomes effective for the annual period beginning on January 1, 2025, with early adoption permitted. The Company is currently evaluating the impact that the adoption of ASU 2023-09 may have on its consolidated financial statements.
As of September 30, 2024, there are no other new, or existing recently issued, accounting pronouncements that are of significance, or potential significance, that impact the Company’s condensed consolidated financial statements.

Development and Commercialization Agreement with Cipla Technologies LLC (“Cipla”)
On April 15, 2019, the Company entered into a Development and Commercialization Agreement (the “Cipla Agreement”) with Cipla for the co-development and commercialization, on a worldwide exclusive basis, of PUR1900, the Company’s inhaled iSPERSE™ drug delivery system (the “Product”) enabled formulation of the antifungal drug itraconazole, which is only available as an oral drug, for the treatment of all pulmonary indications, including allergic bronchopulmonary aspergillosis (“ABPA”) in patients with asthma. The Company entered into an amendment to the Cipla Agreement on November 8, 2021 (the “Second Amendment”) and a subsequent amendment on January 6, 2024 (the “Third Amendment”). All references to the Cipla Agreement herein refer to the Cipla Agreement, as amended.
The Company received a non-refundable upfront payment of $22.0 million (the “Upfront Payment”) under the Cipla Agreement. Upon receipt of the Upfront Payment, the Company irrevocably assigned to Cipla the following assets, solely to the extent that each covers the Product in connection with any treatment, prevention, and/or diagnosis of diseases of the pulmonary system (“Pulmonary Indications”): all existing and future technologies, current and future drug master files, dossiers, third-party contracts, regulatory filings, regulatory materials and regulatory approvals, patents, and intellectual property rights, as well as any other associated rights and assets directly related to the Product, specifically in relation to Pulmonary Indications (collectively, the “Assigned Assets”), excluding most specifically the Company’s iSPERSE™ technology. A portion of the Upfront Payment was deposited by the Company into a bank account, along with an equal amount from the Company, and was dedicated to the development of the Product (the “Initial Development Funding”). The Initial Development Funding was depleted during the year ended December 31, 2021, at which point the Company and Cipla each became responsible for a portion of the development costs actually incurred as described below (the “Co-Development Phase”).
Pursuant to the Second Amendment, the Company and Cipla were each responsible for 60% and 40%, respectively, of the Company’s overhead costs and the time spent by the Company’s employees and consultants on development of the Product (“Direct Costs”). The Company shared all other development costs with Cipla that were not Direct Costs, such as the cost of clinical research organizations, manufacturing costs and other third-party costs, on a 50/50 basis.
Pursuant to the Third Amendment, the Company and Cipla agreed that, during the period commencing on January 6, 2024 and ending July 30, 2024 (the “Wind Down Period”), the Company would complete all Phase 2b activities, assign or license all patents to Cipla and their registration with the appropriate authorities in regions other than the United States, complete a physical and demonstrable technology transfer and secure all data from the Phase 2b study for inclusion in the safety database. The Company shared costs with Cipla during the Wind Down Period in the same proportions in effect with the Second Amendment discussed above, but subject to a maximum reimbursement amount by Cipla as approved by the joint steering committee. The Company completed all Phase 2b activities by the end of the Wind Down Period. The Company is in the process of settling certain final bills with its PUR1900 contractors, which together comprise an immaterial balance recorded within accounts payable as of September 30, 2024.
Accounting Treatment
The Company originally concluded that because both it and Cipla are active participants in the arrangement and are exposed to the significant risks and rewards of the collaboration, the Company’s collaboration with Cipla is within the scope of Accounting Standards Codification (“ASC”) 808, Collaborative Arrangements (“ASC 808”). The Company concluded that Cipla is a customer since they contracted with the Company to obtain research and development services and a license to the Assigned Assets, each of which is an output of the Company’s ordinary activities, in exchange for consideration. Therefore, the Company has applied the guidance in ASC 606, Revenue from Contracts with Customers (“ASC 606”) to account for the research and development services and a license within the contract. The Company determined that the research and development services and license to the Assigned Assets are considered highly interdependent and highly interrelated and therefore are considered a single combined performance obligation because Cipla cannot benefit from the license without the performance by the Company of the research and development services. Such research and development services are highly specialized and proprietary to the Company and therefore not available to Cipla from any other third party.
The Company initially determined the total transaction price to be $22.0 million – comprised of $12.0 million for research and development services for the Product and $10.0 million for the irrevocable license to the Assigned Assets. Any consideration related to the Co-Development Phase was not initially included in the transaction price as such amounts were subject to the variable consideration constraint. Additionally, the Company has fully constrained any transaction price that might be realized upon commercialization.
Revenue is recognized for the Cipla Agreement as the research and development services are provided using an input method, according to the ratio of costs incurred to the total costs expected to be incurred in the future to satisfy the Company’s obligations. In management’s judgment, this input method is the best measure of the transfer of control of the combined performance obligation. The amounts received that have not yet been recognized as revenue are recorded in deferred revenue on the Company’s consolidated balance sheets, with amounts expected to be recognized in the next 12 months recorded as current.
The Company concluded that the Third Amendment is a contract modification that should be accounted for as part of the existing contract. During the three and nine months ended September 30, 2024, the Company recognized $0.3 million and $6.9 million, respectively, in revenue related to the research and development services and irrevocable license to the Assigned Assets in the Company’s consolidated statements of operations, as compared to $1.8 million and $5.1 million, respectively, recognized during the three and nine months ended September 30, 2023. The revenue recognized during the nine months ended September 30, 2024 was primarily associated with the cumulative catch-up recorded in the three months ended March 31, 2024, from the contract modification, that had been included in deferred revenue at the beginning of the period. As of September 30, 2024, all of the Company’s performance obligations have been satisfied.
Agreements with MannKind Corporation (“MannKind”)
On May 28, 2024, the Company executed certain agreements with MannKind and the Company’s landlord (collectively, the “MannKind Transaction”), all of which closed during July 2024. The agreements with MannKind included a Bill of Sale and Assignment Agreement (the “Bill of Sale”) with respect to the assignment of the Company’s rental facility at 36 Crosby Drive, Bedford, Massachusetts (the “Bedford Facility”) to MannKind along with the transfer of all leasehold improvements, laboratory equipment and other related personal property. In connection with the assignment of the Bedford Facility, the Company, MannKind and Cobalt Propco 2020, LLC (the “Landlord”) entered into an Amendment to Lease and Consent to Assignment of Lease (the “Lease Assignment Agreement”) pursuant to that certain Lease Agreement, dated as of January 7, 2022 (the “Lease Agreement”), by and between the Company and the Landlord. Pursuant to the Lease Assignment Agreement, MannKind assumed all of the Company’s obligations under the Lease Agreement, including all rent and other payments.
In connection with these transactions, the Company and MannKind entered into an Intellectual Property Cross License Agreement (the “Cross License Agreement”). Pursuant to the Cross License Agreement, the Company granted to MannKind (i) an exclusive license to develop, use, manufacture, market, offer and sell iSPERSE formulations of Clofazimine, (ii) an exclusive license to develop, use, manufacture, market, offer and sell formulations of iSPERSE with one more active pharmaceutical ingredients for the treatment of nontuberculous mycobacteria lung disease in humans, (iii) an exclusive license to develop, use, manufacture, market, offer and sell iSPERSE formulations of insulin, (iv) a non-exclusive license to develop, use, manufacture, market, offer and sell formulations of iSPERSE with one more active pharmaceutical ingredients for the treatment of endocrine disease in humans, and (v) a non-exclusive license to develop, use, manufacture, market, offer and sell formulations of iSPERSE with one more active pharmaceutical ingredients for the treatment of interstitial lung diseases (including IPF, PPF and other related lung diseases) in humans (collectively, the “Out-License”).
Additionally, pursuant to the Cross License Agreement, MannKind granted to the Company (i) the exclusive right to develop, use, manufacture, market, offer and sell its single-use disposable dry powder inhaler (including all modifications or improvement thereto made by or on behalf of the Company, the “Cricket Device”) for the inhaled delivery of dihydroergotamine in any formulation whatsoever, including the Company’s PUR3100 treatment of acute migraine and (ii) a non-exclusive license to develop, use, manufacture, market, offer and sell the Cricket Device for the inhaled delivery of one more active pharmaceutical ingredients formulated with iSPERSE for the treatment of neurological disease in humans (collectively, the “In-License”).
Additionally, pursuant to the Master Services Agreement, by and between the Company and MannKind, MannKind shall provide certain development services to the Company, including but not limited to, activities to develop a dry powder formulation of the active pharmaceutical ingredient that the Company provides to MannKind for oral inhalation using iSPERSE.
To maintain continuity of iSPERSE platform knowledge, MannKind hired certain members of the Company’s research and development staff in July 2024.
Accounting Treatment
The Company determined that the MannKind Transaction represents a combined agreement for accounting purposes, as the individual components have the same overall commercial objectives and the consideration under each component is dependent on the other components.
The consideration due to the Company in the MannKind Transaction consists solely of the non-cash consideration in the form of the In-License. The fair value of the non-cash consideration received should be allocated to the other components of the MannKind Transaction to determine the consideration received for the other components. The Company determined that the fair value of the In-License is immaterial given that adequate alternative inhaler devices are already available on the market (and indeed, the Company has already established use of another third-party inhalation device in their PUR3100 Phase 1 trial that performed well as a DHE delivery device as reported in a peer-reviewed publication), and considering optional purchases of Cricket Devices are at market prices. Accordingly, the consideration allocated to other components of the MannKind Transaction was immaterial.
During the three months ended June 30, 2024, the Company accounted for the Lease Assignment Agreement upon execution as a lease modification that reduced the lease term to the assignment date in July 2024. Accordingly, the Company remeasured its operating lease liability as of the modification date to reflect the decrease in fixed lease payments, with the amount of the remeasurement, $8.4 million, adjusted by a corresponding reduction to the right-of-use asset.
The Company determined that its operating lease right-of-use asset and property and equipment subject to the Bill of Sale represented a disposal group that became held for sale during the second quarter of 2024 and remained classified as held for sale as of June 30, 2024. The Company recorded a full write-down of the disposal group’s carrying value as of June 30, 2024, in the amount of $2.6 million. Upon the closing of the MannKind Transaction in July 2024, the disposal group was disposed.
Concurrent with the closing of the MannKind Transaction, the Company terminated and MannKind hired the majority of the Company’s research and development employees, representing approximately two-thirds of the Company’s workforce at the time. The Company agreed to provide termination benefits to these employees, which has been fully paid as of September 30, 2024.

| Common Stock | 7. Common Stock
In May 2021, the Company entered into an At-The-Market Sales Agreement (the “Sales Agreement”) with H.C. Wainwright and Co., LLC (“HCW”) to act as the Company’s sales agent with respect to the issuance and sale of up to $20.0 million of the Company’s shares of common stock, from time to time in an at-the-market public offering (the “ATM Offering”). Upon filing of the Annual Report, the Company continued to be subject to General Instruction I.B.6 of Form S-3, pursuant to which in no event will the Company sell its common stock in a registered primary offering using Form S-3 with a value exceeding more than one-third of its public float in any 12 calendar month period so long as its public float remains below $75,000,000. Therefore, the amount that may be able to be raised using the ATM Offering will be significantly less than $20,000,000, until such time as the Company’s public float held by non-affiliates exceeds $75,000,000.
Sales of common stock under the Sales Agreement are made pursuant to an effective shelf registration statement on Form S-3, which was filed with the SEC on May 17, 2024, and subsequently declared effective on May 30, 2024 (File No. 333-279491), and a related prospectus. HCW acts as the Company’s sales agent on a commercially reasonable efforts basis, consistent with its normal trading and sales practices and applicable state and federal laws, rules and regulations and the rules of The Nasdaq Capital Market (“Nasdaq”). If expressly authorized by the Company, HCW may also sell the Company’s common stock in privately negotiated transactions. There is no specific date on which the ATM Offering will end, there are no minimum sale requirements and there are no arrangements to place any of the proceeds of the ATM Offering in an escrow, trust or similar account. HCW is entitled to compensation at a fixed commission rate of 3.0% of the gross proceeds from the sale of the Company’s common stock pursuant to the Sales Agreement.
During the nine months ended September 30, 2024, shares of the Company’s common stock were sold under the Sales Agreement.

The Company has limited leasing activities as a lessee which are primarily related to its corporate headquarters, which were relocated during the third quarter of 2023 and again during the third quarter of 2024.
In June 2024, the Company entered into a short-term lease agreement for its new headquarters at 945 Concord Street, Framingham, Massachusetts. No lease liability or right-of-use asset has been recorded for this short-term lease, and the short-term lease cost associated with this lease is immaterial.
Previous Headquarters
On May 28, 2024, as part of the MannKind Transaction (see further discussion in Note 6, Significant Agreements), the Company and the Landlord executed the Lease Assignment Agreement to assign the Lease Agreement to MannKind in July 2024. The Company accounted for the Lease Assignment Agreement as a lease modification that reduced the lease term to the assignment date in July 2024. Accordingly, during the three months ended June 30, 2024, the Company remeasured its lease liability as of the modification date to reflect the decrease in fixed lease payments, with the amount of the remeasurement, $8.4 million, adjusted by a corresponding reduction to the right-of-use asset.
Following the closing of the MannKind Transaction, $1.4 million of restricted cash was released in August 2024, which had been held in a depository account at a financial institution to collateralize a conditional stand-by letter of credit related to the Lease Agreement.

The Company had no income tax expense due to operating losses incurred for the three and nine months ended September 30, 2024 and 2023.
Management of the Company evaluated the positive and negative evidence bearing upon the realizability of its deferred tax assets and determined that it is more likely than not that the Company will not recognize the benefits of the deferred tax assets. As a result, a full valuation allowance was recorded as of September 30, 2024 and December 31, 2023.
The Company applies ASC 740, Income Taxes, for the financial statement recognition, measurement, presentation, and disclosure of uncertain tax positions taken or expected to be taken in income tax returns. Unrecognized tax benefits represent tax positions for which reserves have been established. A full valuation allowance has been provided against the Company’s deferred tax assets, so that the effect of the unrecognized tax benefits is to reduce the gross amount of the deferred tax asset and the corresponding valuation allowance. The Company has no material uncertain tax positions as of September 30, 2024 and December 31, 2023.

| Accounting Policies [Abstract] | |
| Basis of Presentation | Basis of Presentation
The condensed consolidated financial statements of the Company included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted from this report, as is permitted by such rules and regulations. Accordingly, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on March 28, 2024 (the “Annual Report”).
The financial information as of September 30, 2024, and for the three and nine months ended September 30, 2024 and 2023, is unaudited. In the opinion of management, all adjustments (including those which are normal and recurring) considered necessary for a fair presentation of the interim financial information have been included. The balance sheet data as of December 31, 2023 was derived from audited consolidated financial statements. The results of the Company’s operations for any interim periods are not necessarily indicative of the results that may be expected for any other interim period or for a full fiscal year.
Based on its current operating plan, the Company believes that its cash and cash equivalents as of September 30, 2024, will be adequate to fund its currently anticipated operating expenses for at least twelve months from the date these condensed consolidated financial statements are issued. The Company will need to secure additional funding in the future, from one or more equity or debt financings, collaborations, or other sources, in order to carry out all of the Company’s planned research and development activities and regulatory activities; commercialize product candidates; or conduct any substantial, additional development requirements requested by the FDA. Additional funding may not be available to the Company on acceptable terms, or at all. If the Company is unable to secure additional capital, it will be required to significantly decrease the amount of planned expenditures and may be required to cease operations. In addition, any disruption in the capital markets could make any financing more challenging, and there can be no assurance that Pulmatrix will be able to obtain such financing on commercially reasonable terms or at all. Curtailment of operations would cause significant delays in the Company’s efforts to develop and introduce its products to market, which is critical to the realization of its business plan and the future operations of the Company.
|
| Use of Estimates | Use of Estimates
In preparing the condensed consolidated financial statements in conformity with U.S. GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, as well as the reported amounts of expenses during the reporting period. Due to inherent uncertainty involved in making estimates, actual results may differ from these estimates. On an ongoing basis, the Company evaluates its estimates and assumptions. The most significant estimates and assumptions in the Company’s condensed consolidated financial statements have included, but are not limited to, estimates of future expected costs in order to derive and recognize revenue and estimates related to clinical trial accruals and upfront deposits.

| Concentrations of Credit Risk | Concentrations of Credit Risk
Cash is a financial instrument that potentially subjects the Company to concentrations of credit risk. For all periods presented, substantially all of the Company’s cash was deposited in accounts at a single financial institution that management believes is creditworthy, and the Company has not incurred any losses to date. The Company is exposed to credit risk in the event of default by this financial institution for amounts in excess of the Federal Deposit Insurance Corporation insured limits.
For the three and nine months ended September 30, 2024, revenue from two customers accounted for 100% of revenue recognized in the accompanying condensed consolidated financial statements. For the three and nine months ended September 30, 2023, revenue from one customer accounted for 100% of revenue recognized in the accompanying condensed consolidated financial statements. As of September 30, 2024 and December 31, 2023, one customer accounted for 100% of accounts receivable.

| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies
The Company’s significant accounting policies are described in Note 2, Summary of Significant Accounting Policies and Recent Accounting Standards, in the Annual Report. During the nine months ended September 30, 2024, the Company did not make any changes to its significant accounting policies.

| Recent Accounting Pronouncements | Recent Accounting Pronouncements
From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”) or other standard setting bodies that are adopted by the Company as of the specified effective date. The Company did not adopt any new accounting pronouncements during the nine months ended September 30, 2024 that had a material effect on its condensed consolidated financial statements.
In November 2023, the FASB issued Accounting Standard Update 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). The guidance in ASU 2023-07 expands prior reportable segment disclosure requirements by requiring entities to disclose significant segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and details of how the CODM uses financial reporting to assess their segment’s performance. The guidance is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The standard is required to be applied retrospectively upon adoption. The Company is currently evaluating the impact that the adoption of ASU 2023-07 may have on its condensed consolidated financial statements.
In December 2023, the FASB issued Accounting Standard Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). The guidance in ASU 2023-09 improves the transparency of income tax disclosures by greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The standard becomes effective for the annual period beginning on January 1, 2025, with early adoption permitted. The Company is currently evaluating the impact that the adoption of ASU 2023-09 may have on its consolidated financial statements.
As of September 30, 2024, there are no other new, or existing recently issued, accounting pronouncements that are of significance, or potential significance, that impact the Company’s condensed consolidated financial statements. |
