Alnylam Pharmaceuticals, Inc. is a biopharmaceutical company primarily dedicated to the discovery, development, and commercialization of innovative therapeutic solutions leveraging ribonucleic acid interference (RNAi) technology. Its robust pipeline of RNAi-based treatments addresses a range of critical therapeutic areas, including inherited genetic disorders, cardio-metabolic conditions, hepatic infectious diseases, and central nervous system (CNS) and ocular disorders. Currently, Alnylam offers several approved therapies: ONPATTRO (patisiran) for adults suffering from polyneuropathy associated with hereditary transthyretin-mediated amyloidosis; GIVLAARI for adult patients with acute hepatic porphyria (AHP); and OXLUMO (lumasiran) for primary hyperoxaluria type 1 (PH1).

Alnylam also engages in strategic alliances with other pharmaceutical leaders. Notable collaborations include those with Regeneron Pharmaceuticals, Inc., focused on discovering and developing RNAi therapeutics for ocular and CNS targets, and with Sanofi Genzyme for broader RNAi therapeutic development and commercialization efforts.
