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.

On December 15, 2022, 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.

During the American Society of Nephrology (ASN) Kidney Week, we presented new 12-month results from the ILLUMINATE-C Phase 3 study of lumasiran in patients of all ages with primary hyperoxaluria type 1 (PH1) and advanced kidney disease. Additional research was presented on the development and validation of a novel assay to determine oxalate concentration in plasma.

New 18-month findings evaluating Neurofilament light chain (NfL) as a potential biomarker of treatment response in patients with hATTR amyloidosis with polyneuropathy were presented at the 147th annual meeting of the American Neurological Association (ANA).

At the Heart Failure Society of America (HFSA) Annual Scientific Meeting 2022, we presented results from the APOLLO-B Phase 3 study of patisiran, an investigational RNAi therapeutic in development for the treatment of transthyretin-mediated (ATTR) amyloidosis with cardiomyopathy.

Results from a post-hoc analysis of patients on hemodialysis in the ongoing ILLUMINATE-C Phase 3 open-label study of lumasiran in patients with advanced primary hyperoxaluria type 1 (PH1) were presented at the International Pediatric Nephrology Association (IPNA) Congress (Sept. 7-11, 2022).

We are hosting a series of online “RNAi Roundtables” at which Alnylam scientists and program leaders, as well as medical thought leaders, will review recent progress in a selection of our pipeline programs and platform innovations, and provide perspectives on clinical developments and unmet needs.
