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.

Positive results from the ILLUMINATE-A Phase 3 study of lumasiran, an investigational RNAi therapeutic in development for the treatment of Primary Hyperoxaluria Type 1 (PH1), were presented by study investigators at the European Renal Association-European Dialysis and Transplant Association (ERA-EDTA) International Congress, held June 6-9, 2020 as a virtual event.

We presented new long-term results from the global Open-Label Extension (OLE) study of ONPATTRO® (patisiran) at the European Academy of Neurology (EAN) Virtual Congress, held May 23-26, 2020. In addition, results were presented from a Phase 3b trial evaluating treatment with patisiran in patients with hATTR amyloidosis with disease progression after receiving an orthotopic liver transplant (post-OLT). A post-hoc analysis of the ENVISION Phase 3 study of GIVLAARI® (givosiran) was also presented.

An abstract describing new 12-month interim data from the ongoing ENVISION open-label extension (OLE) study of givosiran in patients with acute hepatic porphyria (AHP) has been published online by the European Association for the Society of the Liver (EASL) on the International Liver Congress™ (ILC 2020) website.  The data will be presented during the ILC 2020 (London, UK) which was rescheduled to August 25-28, 2020 due to the COVID-19 pandemic.

We presented new positive efficacy results from the ongoing Phase 2 open-label extension (OLE) study of lumasiran, an investigational subcutaneously administered RNAi therapeutic in development for the treatment of primary hyperoxaluria type 1 (PH1), at the American Society of Nephrology (ASN) 2019 Annual Meeting, held November 5-10 in Washington, DC.

We presented results on the pediatric cohort of patients (N=16; age range 6-17) from the Phase 1/2 study of lumasiran, an investigational RNAi therapeutic targeting glycolate oxidase (GO) for the treatment of primary hyperoxaluria type 1 (PH1), at the International Pediatric Nephrology Association (IPNA) 2019 Annual Meeting, held October 17-21 in Venice, Italy.

ONPATTRO® (patisiran) is approved in the U.S. and Canada for the treatment of the polyneuropathy of hATTR amyloidosis in adults, in the EU for the treatment of hATTR amyloidosis in adults with stage 1 or stage 2 polyneuropathy, and in Japan for the treatment of transthyretin (TTR) type familial amyloidosis with polyneuropathy. Vutrisiran is an investigational RNAi therapeutic in development for the treatment of ATTR amyloidosis.
