MIAMI, Aug. 10, 2023 (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 second quarter ended June 30, 2023.

“Avenue continues to make significant progress across our compelling pipeline of first- and best-in-class neurologic therapies for patients facing great unmet need,” said Alexandra MacLean, M.D., Chief Executive Officer of Avenue. “Recently, we advanced our lead product candidate AJ201 into the clinic, dosing the first patient in the Phase 1b/2a clinical trial for spinal and bulbar muscular atrophy (“SBMA”), a rare and devastating disease with no effective approved therapies. Additionally, we reported promising preclinical results for BAER-101 that show robust anti-seizure activity in a translational animal model of absence epilepsy. These results, combined with BAER-101’s safety and tolerability profile in multiple clinical trials, demonstrate its potential to overcome treatment limitations of both current standard-of-care as well as investigational therapies in development, and we look forward to initiating a Phase 2a trial in 2024. Importantly, we also reached alignment with the U.S. Food and Drug Administration (“FDA”) on the final Phase 3 safety study design for IV tramadol, a crucial milestone for the program as positive results have the potential to support the submission of a complete response to the second Complete Response Letter from the FDA and a subsequent U.S. approval. Pending additional financing, we aim to initiate this Phase 3 safety study shortly. We look forward to providing updates as we continue to advance these much-needed drugs for patients in the coming months, and execute on our mission of providing impactful therapies to patients suffering from neurologic diseases.”

Recent Corporate Highlights:

AJ201

• In July 2023, the first patient was dosed in the Phase 1b/2a clinical trial of AJ201 for the treatment of SBMA, also known as Kennedy’s Disease. The 12-week, multicenter, randomized, double-blind Phase 1b/2a clinical trial of AJ201 is expected to enroll approximately 24 patients, randomly assigned to AJ201 (600 mg/day) or placebo. Topline data for the Phase 1b/2a clinical trial of AJ201 in SBMA are expected in the first half of 2024. More information about this study can be found at ClinicalTrials.gov (Identifier: NCT05517603). Information on clinicaltrials.gov does not constitute part of this release.

BAER-101

• In August 2023, Avenue reported preclinical results for BAER-101, a potentially best-in-class selective GABA-A α2,3 positive allosteric modulator, demonstrating that it significantly suppressed seizures in a translational animal model of absence epilepsy. In an in vivo evaluation using the SynapCell’s Genetic Absence Epilepsy Rat from Strasbourg (“GAERS”) model of absence epilepsy, BAER-101 fully suppressed seizure activity with a minimal effective dose of 0.3 mg/kg, PO. The effect was fast in onset and stable throughout the duration of testing. The detailed preclinical results will be presented at an upcoming scientific meeting. The combination of safety and tolerability in hundreds of patients and the preclinical efficacy data support BAER-101’s continued development in a Phase 2a trial, which the Company plans to initiate in 2024.

IV Tramadol

• In July 2023, Avenue reached an agreement with the FDA on the trial design and analysis approach of the Phase 3 safety study for intravenous (“IV”) tramadol, which is in development for the treatment of acute post-operative pain in a medically supervised setting. The 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 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 is submitting the revised protocol to the FDA including the statistical plan, which reflects the now agreed upon study design, for final review. Pending additional financing, Avenue aims to initiate the Phase 3 safety study as soon as feasible.
