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.

Results from the HELIOS-A Phase 3 study of vutrisiran in patients with the polyneuropathy of hATTR amyloidosis evaluating the impact of baseline polyneuropathy severity on treatment response were presented during the 2023 Peripheral Nerve Society Annual Meeting.

Nine month results from the randomized treatment extension (RTE) period of the HELIOS-A study of vutrisiran in patients with the polyneuropathy of hereditary ATTR amyloidosis were presented at the Italian Association for the Study of the Peripheral Nervous System.

Eighteen month results from the APOLLO-B Phase 3 study of patisiran in patients with ATTR amyloidosis with cardiomyopathy were presented at the Annual Congress of the Heart Failure Association of the European Society of Cardiology (Heart Failure 2023). A post-hoc analysis of the APOLLO-B study assessing the efficacy of patisiran in patients with hATTR amyloidosis with cardiomyopathy and polyneuropathy (mixed phenotype) was also presented.

New 30-month results from the ILLUMINATE-B Phase 3 study of lumasiran in pediatric patients with primary hyperoxaluria type 1 (PH1) shared at the Pediatric Academic Societies (PAS) 2023 Meeting.

New data from a post-hoc analysis of the HELIOS-A Phase 3 study comparing efficacy outcomes with vutrisiran versus patisiran in hATTR amyloidosis with polyneuropathy were presented during the 2023 AAN Annual Meeting. Final results from a Phase 4 observational study evaluating the effect of patisiran on polyneuropathy and cardiomyopathy in patients with hATTR amyloidosis with V122I/T60A variants were also presented.
