Autobahn Therapeutics, based in San Diego, reported promising topline data from its Phase 2 AMPLIFY-BD trial for elunetirom, an investigational treatment for bipolar I and II depression. The trial demonstrated a 16.8-point improvement in the Hamilton Depression Rating Scale (HAMD-17) total score, achieving statistical significance (p<0.001). Notably, 75% of participants responded to treatment, and 50% achieved remission by Week 6, with rapid effects seen as early as Week 2. Elunetirom, a CNS thyroid hormone receptor agonist, aims to enhance brain energy metabolism and neuroplasticity, presenting a differentiated mechanism for treating depression. The treatment exhibited a favorable safety profile, with no serious adverse events reported. The U.S. FDA has granted elunetirom Fast Track designation, expediting its development process. Autobahn plans to present full trial results at a medical conference in 2026 and is also exploring elunetirom's efficacy in major depressive disorder through an ongoing Phase 2 trial, with results expected later in 2026. This research addresses a significant unmet need in bipolar depression, which affects approximately 7 million adults in the U.S.
