Gossamer Bio submitted its first NDA to the U.S. FDA for seralutinib to treat pulmonary arterial hypertension (PAH). The submission is supported by Phase 3 PROSERA data and confirmatory Phase 2 TORREY results, plus supportive analyses. A June 2026 Pre-NDA Type B meeting yielded FDA minutes describing PROSERA's treatment effects as review issues rather than filing issues and providing guidance on submission format. The FDA will decide whether to accept the NDA for filing after an initial review, expected later in 2026. If approved, seralutinib could become a new PAH therapy with potential broader opportunities in PH-ILD and other indications, marking a significant milestone for Gossamer and its development team. NDA filing based on PROSERA and TORREY could materially shift Gossamer's trajectory and valuation if approved.
