Purchases of Assets Acquisition of Intellectual Property Rights from Patagonia Pharmaceuticals LLC (“Patagonia”) On February 28, 2019, the Company acquired the intellectual property rights to a topical formulation of isotretinoin for the treatment of congenital ichthyosis and identified as TMB-001, formerly PAT-001, from Patagonia (the “TMB-001 Acquisition”) pursuant to an asset acquisition agreement (the “Asset Acquisition Agreement”). Upon closing of the TMB-001 Acquisition, the Company paid a one-time upfront payment of $50,000 to Patagonia. Patagonia is entitled to up to $27.0 million of cash milestone payments relating to certain regulatory and commercial achievements of TMB-001, with the first being $4.0 million for the initiation of a Phase 3 pivotal trial, as agreed with the FDA and defined as the first patient enrolled in such trial for the product. In addition, Patagonia is entitled to net sales earn-out payments ranging from low single digits to mid-double digits. The Company is responsible for all development activities. The first regulatory and commercial milestone was reached in June 2022, and as such the first $4.0 million milestone payment has been accrued at June 30, 2022. There were no milestone payments accrued at December 31, 2021, because the potential regulatory and commercial milestones were not considered probable. On July 20, 2022, the Company entered into an amendment to the Asset Acquisition Agreement with Patagonia (the “Amendment”). Pursuant to the Amendment, the Company and Patagonia agreed to extend the time for Company’s payment of the first milestone payment, which became payable upon the Company commencing patient enrollment in its Phase 3 ASCEND clinical trial in the second quarter of 2022. The first milestone payment is now payable by the Company in two tranches, with $2.25 million due on September 1, 2022 and $1.75million plus an additional $0.315 million for a total of $2.065 million due on September 1, 2023. Further, the Company granted Patagonia a security interest in TMB-001 and certain other assets. On June 26, 2019, the Company acquired the intellectual property rights to a locally administered formulation of Sitaxsentan for the treatment of cutaneous fibrosis and/or pigmentation disorders, and identified as TMB-003, formerly PAT-S03, from Patagonia (the “TMB-003 Acquisition”). Upon closing of the TMB-003 Acquisition, the Company paid a one-time upfront payment of $20,000 to Patagonia. Patagonia is entitled to up to $10.25 million of cash milestone payments relating to certain regulatory and commercial achievements of TMB-003, with the first being a one-time payment of $250,000 upon the opening of an IND with the FDA. In addition, Patagonia is entitled to net sales earn-out payments ranging from low to mid-single digits. The Company is responsible for all development activities. The potential regulatory and commercial milestones are not yet considered probable, and therefore no milestone payments have been accrued at June 30, 2022, and December 31, 2021, respectively. On January 12, 2021, the Company announced that the FDA had granted orphan drug designation to TMB-003. Acquisition of License from AFT Pharmaceuticals Limited (“AFT”) On July 5, 2019, the Company and AFT entered into a license agreement which provides the Company with (i) an exclusive license to certain licensed patents, licensed know-how and AFT trademarks to commercialize Pascomer in the United States, Canada and Mexico and (2) a co-exclusive license to develop Pascomer in this territory. Concurrently, the Company granted to AFT an exclusive license to commercialize Pascomer outside of the Company’s territory and co-exclusive sublicense to develop and manufacture the licensed product for commercialization outside of the Company’s territory (the “AFT License Agreement”). The development of Pascomer had been conducted pursuant to a written development plan, written by AFT and approved by the joint steering committee, which had been reviewed on at least an annual basis. AFT agreed to perform clinical trials of Pascomer in the specified territory and perform all CMC (chemistry, manufacturing and controls) and related activities to support regulatory approval. The Company was responsible for all expenses incurred by AFT during the term of the AFT License Agreement and equally shared all costs and expenses with AFT, incurred by AFT for development and marketing work performed in furtherance of regulatory approval and commercialization worldwide, outside of the specified territory. The Company was entitled to receive 50% of the economics (royalties and milestones) in any licensing transaction that AFT executes outside of North America, Australia, New Zealand, and Southeast Asia. In March 2021 the Company announced that AFT had signed an exclusive license and supply agreement with Desitin Arzneimittel GmbH (“Desitin”) for Pascomer for the treatment of facial angiofibromas associated with tuberous sclerosis complex (TSC) in Europe. Pursuant to the AFT License Agreement, the Company was obligated to reimburse AFT for previously spent development costs, subject to certain limitations, and to pay a one-time, irrevocable, and non-creditable upfront payment to AFT, payable in scheduled installments which was paid in 2020. AFT is entitled to up to $25.5 million of cash milestone payments if TMB-002 achieved certain regulatory and commercial milestones, with the first payment of $1.0 million upon the successful completion of a Phase 2b trial defined as the achievement of the trial’s primary clinical endpoints. In addition, AFT was entitled to net sales royalties ranging from high single digits to low double digits for the program licensed. The potential regulatory and commercial milestones were not considered probable as of June 30, 2022, and therefore no milestone payments have been accrued at June 30, 2022, and December 31, 2021, respectively. On April 4, 2022, Nobelpharma America LLC (“Nobelpharma”) announced that the U.S. Food and Drug Administration (FDA) had approved HYFTOR™ (sirolimus topical gel) 0.2% as the first topical treatment indicated for facial angiofibroma associated with tuberous sclerosis complex in adults and children six (6) years of age or older. Nobelpharma’s formulation has orphan drug status for this indication. As the Company’s product TMB-002, a topical rapamycin cream, is intended for treatment of the same indication, the Company does not intend to proceed with a pivotal Phase 3 clinical trial of TMB-002 in facial angiofibromas at this time, but instead may evaluate potential strategic opportunities for the asset in markets outside of the U.S. and/or other indications. On July 23, 2022, the Company provided written notice to AFT of its decision to terminate the AFT License Agreement because the Company believes there is no longer a commercially reasonable path to approval and commercialization for TMB-002 in the United States for facial angiofibromas associated with tuberous sclerosis complex. Additionally, following the receipt and analysis of topline data for the Phase II Clinical Trial (as defined in the AFT License Agreement) it was determined that the study failed to meet its primary efficacy endpoint. Under the AFT License Agreement, the Company was required to provide 120 days’ prior written notice of termination to AFT which was waived by AFT on July 25, 2022 (the “Termination Date”). On the Termination Date, the rights and licenses to TMB-002 reverted to AFT, among other things, as set forth in the AFT License Agreement. As the agreement with AFT has been terminated we will no longer receive any royalties or milestones for any transactions under this agreement. Other The Company disbursed approximately $2.225 million for a prepaid CRO payment for the start of its Phase 3 ASCEND study evaluating TMB-001 in CI in April 2022. Approximately $617,000 of this payment remains in prepaid research and development at June 30, 2022.
