(Euronext: AB) is a clinical-stage French pharmaceutical company that researches, develops and commercializes protein kinase inhibitors and related targeted therapies for cancers, inflammatory diseases, neurodegenerative disorders and other conditions with high unmet medical needs in humans and veterinary medicine; its lead product masitinib, a highly selective tyrosine kinase inhibitor already approved for veterinary use, advances in late-stage human trials for amyotrophic lateral sclerosis (ALS), multiple sclerosis, oncology and other indications including a new confirmatory Phase 3 study (AB23005) authorized by the FDA and select European countries in 2025, while its second key compound AB8939, a next-generation microtubule destabilizer, progresses through Phase 1/2 in acute myeloid leukemia (AML) with promising early efficacy data and plans for an expansion cohort. Founded in 2001 and headquartered at 3 Avenue George V in Paris, France, the company employs around 40 staff primarily focused on R&D, operates globally through clinical programs in Europe, North America and beyond including a U.S. subsidiary in New Jersey, and markets masitinib for veterinary applications while pursuing human approvals. Recent developments include multiple 2025 capital raises totaling over EUR 9 million through private placements and its PACT program with Alpha Blue Ocean to fund AB8939 advancement and masitinib studies, ongoing re-examination of masitinib marketing authorizations for ALS with the EMA and Health Canada, and operational restructuring to prioritize its dual-platform pipeline amid reduced bank debt.
