Seralutinib is an investigational, inhaled, small molecule, platelet-derived growth factor receptor (PDGFR), colony-stimulating factor 1 receptor (CSF1R) and mast/stem cell growth factor receptor kit (c-KIT). It was intentionally designed to target the mechanisms that underlie pulmonary hypertension and to be delivered to the site of disease, via dry powder inhaler.
Seralutinib is currently being evaluated in a phase 3 clinical trial for the treatment of pulmonary arterial hypertension (PAH). Additionally, Gossamer Bio expects to activate the first clinical sites for a global phase 3 registrational clinical trial for the treatment of pulmonary hypertension associated with interstitial lung disease (PH-ILD) in 4Q25.
