Alnylam Scraps Interim Analysis For Heart Disease Trial, Rethinks Plans For Another Rare Disorder Program

Tucked Away in the Q3 earnings release, Alnylam Pharmaceuticals Inc (NASDAQ: ALNY) revealed it would scrap plans to launch a Phase 3 trial for vutrisiran in the rare Stargardt disease as it continues to evaluate the impact of the Inflation Reduction Act.
The Stargardt disease study was slated to begin before the end of the year.
Additionally, Alnylam has decided not to perform an optional interim analysis of the closely watched Helios-B trial in transthyretin-mediated amyloidosis with cardiomyopathy (ATTR-CM). Instead, it will wait for a top-line readout that’s expected in early 2024.
In June, Amvuttra (vutrisiran) got its FDA approval in hereditary ATTR polyneuropathy, a neurological form of ATTR.
The drug just completed its first quarter on the market.
