Description of Business The Company is a clinical stage biopharmaceutical company advancing therapies that aim to aid patients suffering with acute and chronic gastrointestinal complications stemming from post-operative digestive enzyme damage.

The Company has experienced losses and negative cash flows from operations since its inception. At September 30, 2022, the Company had an accumulated deficit of $105.2 million and cash and cash equivalents of $14.0 million. The Company expects to continue to incur losses into the foreseeable future.

Management anticipates continuing to raise capital from the sale of its securities or through agreements, such as entering into potential partnering events for Company’s existing technology. However, no assurance can be given as to whether the Company will achieve these objectives. Based on the Company’s current business plan, management believes that existing cash and cash equivalents will not be sufficient to fund the Company’s obligations for at least 12 months from the date of issuance of these financial statements. The Company’s ability to execute its operating plan depends on its ability to obtain additional funding through equity offerings, debt financings or potential licensing and collaboration arrangements. The condensed consolidated financial statements have been prepared assuming the Company will continue as a going concern, which contemplates the realization of assets and settlement of liabilities in the normal course of business. However, the Company’s current working capital, anticipated operating expenses and net operating losses raise substantial doubt about its ability to continue as a going concern for a period of one year following the date that these condensed consolidated financial statements are issued. The condensed consolidated financial statements do not include any adjustments for the recovery and classification of assets or the amounts and classification of liabilities that might be necessary should the Company be unable to continue as a going concern. The Company plans to continue to fund its operations through cash and cash equivalents on hand, as well as through future equity offerings, debt financings, other third-party funding, and potential licensing or collaboration arrangements. Refer to Note 6, Stockholders' Equity, for discussion of the recent financings undertaken by the Company. There can be no assurance that additional funds will be available when needed from any source or, if available, will be available on terms that are acceptable to the Company. Even if the Company raises additional capital, it may also be required to modify, delay or abandon some of its plans which could have a material adverse effect on the Company’s business, operating results and financial condition and the Company’s ability to achieve its intended business objectives. Any of these actions could materially harm the Company’s business, results of operations and future prospects. COVID-19 In April 2020, as a result of impacts and risks associated with the COVID-19 pandemic (COVID-19), the Company paused enrollment and program activities surrounding the Company’s clinical trials of its lead therapeutic candidate, LB1148, due primarily to slower enrollment. The Company's phase 2 clinical study for the prevention of post-surgical abdominal adhesions re-started in February 2022, and in June 2022 the Company initiated its phase 3 clinical study for the return of bowel function. Notwithstanding, the Company paused enrollment in this phase 3 clinical study pending the determination of next steps for the study. The Company cannot predict how legal and regulatory responses to ongoing concerns about COVID-19 or other major public health issues will impact the Company’s business, nor can it predict potential adverse impacts related to the availability of capital to fund the Company’s operations. Any of these factors, alone or in combination with others, could harm the Company’s business, results of operations, financial condition or liquidity. However, the magnitude, timing, and duration of any such potential financial impacts cannot be reasonably estimated at this time.
