We are a clinical-stage biopharmaceutical company dedicated to the development of novel therapeutics for high unmet medical needs, including treatment-resistant metastatic breast cancer and amyotrophic lateral sclerosis ("ALS"), with the goal of improving patients' lives.

Following a review of potential therapeutic and business opportunities, we acquired rights to a promising late-stage asset, lasofoxifene, for the potential treatment of ESR1-mutated ("mESR1") metastatic breast cancer in December 2025. This late-stage program has generated promising clinical data and we believe it represents a unique and exciting opportunity to diversify our pipeline. We believe this program fits well with our later-stage clinical development experience, and complements our in-house asset, ATH-1105, a Phase-2 ready program for the potential treatment of ALS.
