Capella—the Online Voice of Progress in RNAi

Welcome to Capella, Alnylam’s destination for updates on our work translating the breakthrough discovery of RNA interference (RNAi) into an innovative new class of medicines. We’ve been pioneering RNAi therapeutics since 2002 and are excited to share our ongoing scientific progress.

New preclinical data for ALN-HTT02—an RNAi therapeutic development candidate targeting huntingtin (HTT) for Huntington’s disease (HD)—were presented during the CHDI Foundation’s 19th Annual Huntington’s Disease Therapeutics Conference in Palm Springs, CA . Additional data were presented on the emerging tolerability profile of the underlying C16-siRNA central nervous system delivery platform, highlighting potential differences with antisense oligonucleotides (ASOs) in development for HD.

On December 13, 2023, we hosted a virtual R&D Day event showcasing Alnylam’s late stage clinical efforts, next wave programs, and platform advances. The event included presentations from Alnylam senior leaders as well as guest speakers.

24-month results, including data on the odds of disease progression as assessed by NYHA class and disease stage, from an interim analysis of the open-label extension period of the APOLLO-B Phase 3 study of investigational patisiran in patients with the cardiomyopathy of transthyretin-mediated (ATTR) amyloidosis were presented during the American Heart Association (AHA) Scientific Sessions 2023.

New results from the KARDIA-1 Phase 2 study of zilebesiran, an investigational RNAi therapeutic targeting liver-expressed angiotensinogen (AGT) in development for the treatment of patients with hypertension and high cardiovascular risk, were presented at the American Heart Association (AHA) Scientific Sessions 2023.

New 24-month results from the ILLUMINATE-C Phase 3 study of lumasiran in patients with advanced primary hyperoxaluria type 1 (PH1) were presented at the American Society of Nephrology (ASN) Kidney Week 2023 Meeting. Additional findings from a retrospective study of the natural history of advanced PH1 were also presented.

We presented additional positive interim results for the ongoing single ascending dose portion of the Phase 1 study of ALN-APP, an investigational RNAi therapeutic targeting amyloid precursor protein in development for the treatment of Alzheimer’s disease and cerebral amyloid angiopathy, in a late-breaker session at the 16th Clinical Trials on Alzheimer’s Disease conference.
