Miami, FL – March 18, 2024 – 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.”
