Arrowhead’s plozasiran accepted into FDA STAR program for severe hypertriglyceridemia

Arrowhead Pharmaceuticals announced that the U.S. Food and Drug Administration has accepted its supplemental new drug application for plozasiran into the Split Real‑Time Application Review (STAR) pilot program. The program provides a six‑month priority review for the severe hypertriglyceridemia indication. Arrowhead must file the sNDA by the end of 2026. The drug is already approved for a related rare triglyceride disorder.

The company says the STAR entry will accelerate regulatory review, potentially bringing the product to market sooner and allowing it to keep its priority‑review voucher for future use. Faster approval could improve revenue prospects if the indication is approved.
