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 six-month primary analysis of the ongoing ILLUMINATE-B Phase 3 open-label pediatric study of lumasiran, an investigational RNAi therapeutic in development for the treatment of adults and children with Primary Hyperoxaluria Type 1 (PH1), were presented at the American Society of Nephrology (ASN) Kidney Week 2020, held October 22-25 as a virtual event. Additionally, new 12-month results from the ILLUMINATE-A pivotal Phase 3 study and the ongoing Phase 2 open-label extension (OLE) study were also presented.

We presented progress on our RNAi therapeutics platform efforts at the Oligonucleotide Therapeutics Society (OTS) 2020 Annual Meeting.

On September 3, 2020, we hosted an online RNAi Roundtable to review progress with patisiran and vutrisiran, RNAi therapeutics in development for the treatment of transthyretin-mediated amyloidosis. Of note, we announced we have obtained clinical pharmacology data supporting the potential for a biannual subcutaneous dosing regimen option for vutrisiran, providing further product differentiation as a potential best-in-class agent, and discussed new clinical data presented at the European Society of Cardiology 2020 Congress providing further evidence that treatment with patisiran may lead to substantial reduction in cardiac amyloid burden in ATTR amyloidosis.

During The Digital International Liver Congress™ 2020, we shared new interim data from the Phase 1/2 open-label extension (OLE) study of GIVLAARI® (givosiran) in acute hepatic porphyria (AHP), as well as encore 12-month interim data from the OLE period of the ENVISION Phase 3 study of GIVLAARI.

We published nonclinical research describing the durability of gene silencing by GalNAc-conjugated siRNAs. The article, titled, “Investigating the Pharmacodynamic Durability of GalNAc-siRNA Conjugates,” was selected as a Breakthrough Paper by Nucleic Acids Research.
