Clinical Trial ResultsThe open-label extension following the Phase 2 trial shows sustained hemodynamic and functional gains, including continued pulmonary vascular resistance reduction and incremental six-minute walk distance improvement among patients who remained on drug.
Enrollment And Trial ProgressGossamer completed enrollment in the PROSERA trial with 390 functional class II and III PAH patients, exceeding the original 350-patient target, reflecting strong demand and investigator enthusiasm.
Strategic PartnershipsThe strategic partnership with Chiesi and Gossamer's $212.9 million cash position are key drivers toward a successful commercial launch for seralutinib in PAH, if approved.
