AVENUE THERAPEUTICS, INC

Notes to Financial Statements

Note 1 — Organization, Plan of Business Operations

Avenue Therapeutics, Inc. (the “Company” or “Avenue”) was incorporated in Delaware on February 9, 2015, as a wholly owned subsidiary of Fortress Biotech, Inc. (“Fortress”), to develop and market pharmaceutical products for the acute care setting in the United States. The Company is focused on developing its product candidate, an intravenous (“IV”) formulation of tramadol HCI (“IV Tramadol”), for post-operative acute pain.

Stock Purchase and Merger Agreement

On November 12, 2018, the Company, InvaGen Pharmaceuticals Inc. (“InvaGen”), and Madison Pharmaceuticals, Inc. entered into a Stock Purchase and Merger Agreement (“SPMA”), pursuant to which the Company agreed to its sale in a two-stage transaction. In the first stage, InvaGen agreed to purchase, for $35 million, common shares representing 33.3% of the fully diluted capitalization of the Company. In the second stage, InvaGen would acquire the remaining issued and outstanding capital stock of the Company for approximately $180 million in a reverse subsidiary merger transaction (the “Merger Transaction”). The SPMA was approved by a majority of the Company’s stockholders, including a majority of its non-affiliated stockholders, at its special shareholder meeting on February 6, 2019. On February 8, 2019, InvaGen acquired 5,833,333 shares of the Company’s common stock at $6.00 per share (the “Stock Purchase Transaction”) for net proceeds of $31.5 million after deducting commission fees and other offering costs, representing a 33.3% stake in the Company’s capital stock on a fully diluted basis.

Consummation of the Merger Transaction was conditioned upon, among other things, U.S. Federal Drug Administration (“FDA”) approval of IV Tramadol, its labeling and scheduling, and the absence of certain other restrictions in effect with respect to IV Tramadol. Pursuant to the SPMA, if FDA approval of IV Tramadol was not obtained on or before April 30, 2021, InvaGen would not be subject to the mandatory closing obligations set forth in the SPMA with respect to the Merger Transaction (but would instead retain an option to complete the Merger Transaction up until such time as the SPMA was terminated). Pursuant to the SPMA, the Company could choose to terminate the SPMA after October 31, 2021, if FDA approval of IV Tramadol had not occurred by such time. On November 1, 2021, the Company terminated the SPMA.

Even though the SPMA has been terminated, InvaGen retains certain rights pursuant to the Stockholders Agreement, entered into on November 12, 2018 between the Company, InvaGen and Fortress, and other agreements entered into in connection therewith on such date. These rights exist as long as InvaGen maintains at least 75% of the common shares acquired in the Stock Purchase Transaction and include among other things, the right to restrict the Company from certain equity issuances and changes to the Company’s capital stock without obtaining InvaGen’s prior written consent.

Over the past year, the Company has communicated with InvaGen relating to InvaGen’s assertions that Material Adverse Effects (as defined in the SPMA) have occurred due to the impact of the COVID-19 pandemic on potential commercialization and projected sales of IV Tramadol. Additionally, in connection with the resubmission of the Company’s New Drug Application (“NDA”) in February 2021, InvaGen communicated to the Company that it believes the proposed label for IV Tramadol would also constitute a Material Adverse Effect (as defined in the SPMA) on the purported basis that the proposed label under certain circumstances would make the product commercially unviable. Even though the SPMA has been terminated, it is still possible for InvaGen to pursue monetary claims against the Company and/or Fortress based on the foregoing or other potential causes of action.

Liquidity and Capital Resources

Going Concern

The Company is not yet generating revenue, has incurred substantial operating losses since its inception and expects to continue to incur significant operating losses for the foreseeable future as it executes on its product development plan and may never become profitable. As of December 31, 2021, the Company had an accumulated deficit of $77.0 million.

On October 12, 2020, the Company announced that it had received a Complete Response Letter (“the First CRL”) from the FDA regarding the Company’s NDA for IV Tramadol. The First CRL cited deficiencies related to the terminal sterilization validation and stated that IV Tramadol, intended to treat patients in acute pain who require an opioid, is not safe for the intended patient population. On February 12, 2021, the Company resubmitted its NDA to the FDA for IV Tramadol. The NDA resubmission followed the receipt of official minutes from a Type A meeting with the FDA. The resubmission included revised language relating to the proposed product label and a report relating to terminal sterilization validation. On June 14, 2021, the Company announced that it had received a second Complete Response Letter (the “Second CRL”) from the FDA regarding the Company’s NDA for IV Tramadol. The Second CRL stated that the delayed and unpredictable onset of analgesia with IV Tramadol does not support its benefit as a monotherapy to treat patients in acute pain and that there is insufficient information to support that IV Tramadol in combination with other analgesics is safe and effective for the intended patient population. In particular, the Second CRL stated that, while the primary endpoint was met in two efficacy studies, meaningful pain relief was delayed (accounting for the use of rescue medication, e.g., ibuprofen), and some patients never achieved pain relief. The Company continues to pursue regulatory approval for IV Tramadol and had a Type A meeting with the FDA in July 2021. The FDA did not deviate from any of the positions the FDA previously took in the First CRL and the Second CRL. The Company submitted a formal dispute resolution request (“FDRR”) with the Office of Neuroscience of the FDA on July 27, 2021. On August 26, 2021, the Company received an Appeal Denied Letter from the Office of Neuroscience of the FDA in response to the FDRR submitted on July 27, 2021. On August 31, 2021, the Company submitted a FDRR with the Office of New Drugs (“OND”) of the FDA. On October 21, 2021, the Company received a written response from the OND of the FDA stating that the OND needs additional input from an Advisory Committee in order to reach a decision on the FDRR. For. On February 15, 2022, the Company had its Advisory Committee meeting with the FDA. In the final part of the public meeting, the Advisory Committee voted yes or no on the following question: “Has the Applicant submitted adequate information to support the position that the benefits of their product outweigh the risks for the management of acute pain severe enough to require an opioid analgesic in an inpatient setting?” The results were 8 yes votes and 14 no votes. On March 18, 2022, the Company received an Appeal Denied Letter from the OND in response to the FDRR. The Company is evaluating next steps with regard to IV Tramadol.

As of December 31, 2021, the Company had cash and cash equivalents of $3.8 million. The Company believes that its cash and cash equivalents are only sufficient to fund its operating expenses into the second quarter of 2022. The Company will need to secure additional funds through equity or debt offerings, or other potential sources. Furthermore, under the SPMA, any equity funding must be approved by InvaGen. The Company cannot be certain that additional funding will be available to it on acceptable terms, or at all. These factors individually and collectively raise substantial doubt about the Company’s ability to continue as a going concern within one year from the date of this report. The financial statements do not contain any adjustments that might result from the resolution of any of the above uncertainty.

In addition, the Company experienced minimal impact on its development timelines and its liquidity due to the worldwide spread of COVID-19.

In light of the foregoing, it may be necessary at some point for the Company to seek protection under Chapter 11 of the United States Bankruptcy Code, which could have a material adverse impact on the Company’s business, financial condition, operations and could place its shareholders at significant risk of losing all of their investment. In any such Chapter 11 proceeding, the Company may seek to restructure its obligations or commence an orderly wind-down of its operations and sale of its assets, in either event, holders of equity interests could receive or retain little or no recovery. The Company also notes that the process of exploring refinancing or restructuring alternatives, including those under Chapter 11, may be disruptive to its business and operations.
