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 results from a post hoc subgroup analysis of the ENVISION Phase 3 study evaluating long-term outcomes in patients with acute hepatic porphyria who were not attack-free after the first six months of GIVLAARI® (givosiran) treatment were presented at the European Association for the Study of the Liver (EASL) Congress 2024.

New 54-month results from the Phase 2 open-label extension study evaluating long-term treatment with OXLUMO® (lumasiran) in patients with primary hyperoxaluria type 1 were presented at the 61st European Renal Association (ERA) Congress.

New results from a post-hoc analysis of outpatient heart failure worsening in the APOLLO-B Phase 3 study of patisiran were presented at the 2024 ACC Annual Scientific Session. Additional data were also presented from a meta-regression analysis of the association between change in 6-minute walk distance and survival in transthyretin-mediated amyloidosis with cardiomyopathy.

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.
