Hydromorphone Hydrochloride

– Raised a total of $9.4 million in gross proceeds from warrant exercise transactions since January 2024 – MIAMI, May 15, 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 first quarter ended March 31, 2024. “The first quarter was incredibly productive for Avenue, as we’ve successfully executed on key milestones across our pipeline of CNS treatments,” said Alexandra MacLean, M.D., Chief Executive Officer of Avenue. “We made significant strides advancing our lead clinical program, AJ201, in spinal and bulbar muscular atrophy (“SBMA”), also known as Kennedy’s Disease and look forward to reporting topline data in the middle of 2024. Additionally, this quarter we continued to showcase the potential of BAER-101 for the treatment of epilepsy with preclinical data at the American Society for Experimental Neurotherapeutics (ASENT) Annual Meeting and in the publication, Drug Development Research. We believe that with the proper financing or a partnership, BAER-101 has the potential to make a meaningful difference for patients facing great unmet need. Finally, we reached agreement with the U.S. FDA on the safety study design and statistical analysis approach for IV tramadol, setting this program up for a successful Phase 3 study as soon as the necessary funding is acquired. We look forward to progressing our pipeline in the quarters to come as we seek to bring long-term value to our shareholders and provide impactful therapies to patients suffering from neurologic diseases.” Recent Corporate Highlights: AJ201 (Nrf1 and Nrf2 activator, androgen receptor degradation enhancer for SBMA) In April, Avenue hosted a virtual key opinion leader (“KOL”) event highlighting expert perspectives on SBMA. The event featured Christopher Grunseich, M.D., Lasker Clinical Research Scholar and Investigator and Head of the Inherited Neuromuscular Diseases Unit at the National Institute of Neurological Disorders and Stroke, and Tahseen Mozaffar, M.D., Professor of Neurology, Pathology and Laboratory Medicine, Director of the Division of Neuromuscular Diseases and Director of the ALS and Neuromuscular Center at the University of California, Irvine. The two featured speakers discussed the characteristics and treatment landscape of SBMA, as well as the trial design and potential of AJ201 in SBMA. A replay of the event can be accessed here. BAER-101 (GABAA α2/3 positive allosteric modulator) Avenue presented preclinical results for BAER-101, a potentially best-in-class selective GABAA α2,3 positive allosteric modulator, in the publication Drug Development Research in February 2024 and the 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 GABAA 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, Avenue reached final agreement with the FDA on the safety study protocol and statistical analysis approach for the Phase 3 study of intravenous (“IV”) tramadol, which is being developed for the treatment of acute post-operative pain in a medically supervised setting. The proposed 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. 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. Corporate Highlights In January and May 2024, Avenue raised a total of approximately $9.4 million in gross proceeds from warrant exercise transactions. In April 2024, the Company effected a 1-for-75 reverse stock split of its issued and outstanding common stock which we expect will bring the Company into compliance with Nasdaq’s $1.00 per share minimum bid price requirement for continued listing. Financial Results: Cash Position: As of March 31, 2024, cash and cash equivalents totaled $3.2 million, compared to $1.8 million at December 31, 2023, an increase of $1.4 million. In May 2024, the Company completed a warrant inducement transaction for $4.4 million in gross proceeds. R&D Expenses: Research and development expenses for the first quarter of 2024 were $2.4 million, compared to $1.2 million for the first quarter of 2023. Additionally, there was $4.2 million in expense for the acquisition of the AJ201 license in the first quarter of 2023. G&A Expenses: General and administrative expenses for the first quarter of 2024 were $1.3 million, compared to $1.0 million for the first quarter of 2023. Net Loss: Net loss attributable to common stockholders for the first quarter of 2024 was $4.3 million, or $15.40 per share, compared to a net loss of $7.5 million, or $101.57 per share, for the first quarter of 2023.

- Enrollment completed in Phase 1b/2a clinical trial of AJ201 for spinal and bulbar muscular atrophy; topline data expected in second quarter of 2024 - - Presented positive BAER-101 preclinical data at American Epilepsy Society (AES) and American Society for Experimental Neurotherapeutics (ASENT) Annual Meetings and in publication Drug Development Research - - Final agreement reached with FDA on study design and analysis approach for Phase 3 safety study of IV tramadol – 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 (GABAA α2/3 positive allosteric modulator) Avenue presented preclinical results for BAER-101, a potentially best-in-class selective GABAA 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 GABAA 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.
