Arrowhead Pharmaceuticals: The Fast-Follower Math Behind A $215 Million Voucher Arrowhead Pharmaceuticals is positioned to challenge Ionis in severe hypertriglyceridemia (sHTG) with plozasiran, leveraging a faster launch via a $215M priority review voucher. ARWR's SHASTA-3 and SHASTA-4 Phase III data show plozasiran achieves 79–81% median triglyceride reductions and favorable safety, with quarterly dosing and no liver fat or thrombocytopenia signals. Current financials reflect partner-driven revenue and a strategic buildout for sHTG; liquidity of ~$1.35B post-voucher supports operations into early 2028, but further funding may be needed as SG&A rises.
