Alnylam Pharmaceuticals Plans NDA for Patisiran
Alnylam Pharmaceuticals says it is planning an NDA submission late this year for patisiran, indicated for treating transthyretin-mediated amyloidosis with cardiomyopathy after reporting positive data from the APOLLO-B Phase 3 study. The study met the primary endpoint of change from baseline in the Six-Minute Walk Test at 12 months compared to placebo, according to the company. It also met the first secondary endpoint of change from baseline in quality of life compared to placebo, which was measured by the Kansas City Cardiomyopathy Questionnaire.
On the safety side, Alnylam says five patients (2.8%) on patisiran and eight patients (4.5%) on placebo died. “Furthermore, the number of deaths in the all-cause mortality efficacy analysis was 4 (2.2%) in the patisiran arm and 10 (5.6%) in the placebo arm, determined in accordance with the pre-defined statistical analysis plan, which excluded death due to Covid-19, and treated cardiac transplant as a death event consistent with other studies in the field,” it says. “The patisiran and placebo arms had similar frequencies of adverse events (91.2% and 94.4%, respectively) and serious adverse events (33.7% and 35.4%, respectively).”
