MIAMI, March 18, 2024 (GLOBE NEWSWIRE) — Avenue Therapeutics, Inc. (Nasdaq: ATXI) (“Avenue” or the “Company”), a specialty pharmaceutical company focused on the development and commercialization of therapies for the treatment of neurologic diseases, today reported financial results and recent corporate highlights for the year ended December 31, 2023.

“We made considerable progress across our pipeline of differentiated neurologic therapies in 2023,” said Alexandra MacLean, M.D., Chief Executive Officer of Avenue. “Avenue demonstrated tremendous execution capabilities with our lead clinical program AJ201, a potential first-in-class treatment for spinal and bulbar muscular atrophy (SBMA), also known as Kennedy’s Disease. Within nine months of acquiring the rights to AJ201 in March 2023, we dosed the first patient in the Phase 1b/2a clinical trial, and we completed trial enrollment of 25 SBMA patients across six sites in the U.S. We remain on track to report topline data for AJ201 in the second quarter of 2024, an incredibly exciting milestone for both the Company and patients suffering from SBMA, a debilitating rare neuromuscular disorder with no approved treatments in the U.S. Additionally, we have progressed BAER-101 for the treatment of epilepsy by presenting preclinical data from a translational animal model in multiple peer-reviewed forums. We have also advanced IV tramadol, reaching final agreement with the U.S. Food and Drug Administration (FDA) on the safety study and statistical analysis approach for the final Phase 3 study. Pending additional financing, we look forward to progressing BAER-101 and IV tramadol for patients facing great unmet need. We look forward to another productive year in 2024 as we continue to make significant strides across our clinical pipeline and advance our mission of providing impactful therapies to patients suffering from neurologic diseases.”

Recent Corporate Highlights:

AJ201 (Nrf1 and Nrf2 activator, androgen receptor degradation enhancer for SBMA)

• In January 2024, Avenue completed enrollment in the Phase 1b/2a clinical trial of AJ201 for the treatment of SBMA. The 12-week, multicenter, randomized, double-blind Phase 1b/2a clinical trial of AJ201 enrolled 25 patients randomly assigned to AJ201 (600 mg/day) or placebo. The primary endpoint of the study is to assess safety and tolerability of AJ201 in subjects with clinically and genetically defined SBMA. Topline data for the Phase 1b/2a study are anticipated in the second quarter of 2024. More information about this study can be found at ClinicalTrials.gov (Identifier: NCT05517603).

BAER-101 (GABA_A α2/3 positive allosteric modulator)

• Avenue presented preclinical results for BAER-101, a potentially best-in-class selective GABA_A α2,3 positive allosteric modulator, in three scientific peer-reviewed settings, including the American Epilepsy Society (AES) Annual Meeting in December 2023, the publication Drug Development Research in February 2024 and the American Society for Experimental Neurotherapeutics (ASENT) Annual Meeting in March 2024. The in vivo data showcase BAER-101’s ability to significantly suppress seizures using the SynapCell’s Genetic Absence Epilepsy Rat from Strasbourg (“GAERS”) model of epilepsy. BAER-101 fully suppressed seizure activity in the GAERS model with a minimal effective dose of 0.3 mg/kg, PO, and the effect was fast in onset and stable throughout the duration of testing. The data also demonstrated BAER-101’s ability to selectively target GABA_A α2 and α3 subtypes more than α1 and α5, potentially improving anti-convulsant and anxiolytic activity while minimizing the risk of tolerance and abuse associated with existing treatments in this drug class. Subject to obtaining the necessary financing, which could be provided through a strategic partnership, Avenue plans to initiate a Phase 2a clinical trial of BAER-101 to further study its anti-seizure properties in patients with common or rare epilepsies.

IV Tramadol

• In January 2024, Avenue reached final agreement with the FDA on the safety study protocol and statistical analysis approach for the Phase 3 study for intravenous (“IV”) tramadol, which is in development for the treatment of acute post-operative pain in a medically supervised setting. The final non-inferiority study is designed to assess the theoretical risk of opioid-induced respiratory depression related to opioid stacking on IV tramadol compared to IV morphine. The study will randomize approximately 300 post bunionectomy patients to IV tramadol or IV morphine for pain relief administered during a 48-hour post-operative period. Patients will have access to IV hydromorphone, a Schedule II opioid, for rescue of breakthrough pain. Pending additional financing, Avenue aims to initiate the Phase 3 safety study as soon as feasible. The Company believes that the study can be completed and submitted to the FDA within 12 months of the study’s initiation.

General Corporate

• In March 2024, Avenue announced that the Nasdaq Hearings Panel granted the Company’s request for an extension to evidence compliance with all applicable criteria for continued listing on The Nasdaq Capital Market, including the $1.00 bid price and $2.5 million stockholders’ equity requirements, through May 20, 2024.

2023 Financial Results:

• Cash Position: As of December 31, 2023, cash and cash equivalents totaled $1.8 million, compared to $6.7 million at December 31, 2022, a decrease of $4.9 million. In January 2024, the Company completed a warrant inducement transaction resulting in $5.0 million in gross proceeds.
• R&D Expenses: Research and development expenses for the full year 2023 were $6.1 million, compared to $2.7 million in 2022. Additionally, there was $4.2 million in expense for the acquisition of the AJ201 license in 2023.
• G&A Expenses: General and administrative expenses for the full year 2023 were $4.2 million, compared to $5.3 million in 2022.
• Net Loss: Net loss for the full year 2023 was $10.5 million, or $0.98 per share, compared to a net loss of $3.6 million, or $1.63 per share, in 2022.
