(Nasdaq: GOSS), a clinical-stage biopharmaceutical company focused on the development and commercialization of seralutinib for the treatment of pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD), today announced its financial results for the second quarter ended June 30, 2024 and provided a business update.\n\n\n“Between the continued progress made in the enrollment of the Phase 3 PROSERA Study and the transformational collaboration agreement with the Chiesi Group, Gossamer has made great strides in the second quarter to advance the clinical development and strengthen the market potential of seralutinib,” said Faheem Hasnain, Co-Founder, CEO, and Chairman of Gossamer Bio.\n\n\n“Additionally, we look forward to announcing seralutinib presentations and posters at major medical meetings in the coming months, which continue to support the potential of seralutinib as a novel agent in the treatment of patients with PAH and PH-ILD.”\n\n\nSeralutinib (GB002): Inhaled PDGFR, CSF1R and c-KIT Inhibitor for PAH and PH-ILD\n\n\n\nEnrollment is ongoing in the PROSERA Study, a global registrational Phase 3 clinical trial in patients with WHO Functional Class II and III PAH. The primary endpoint is change in six-minute walk distance (6MWD) from baseline at week 24. Topline results from the PROSERA Study are expected in the fourth quarter of 2025.\n\n\n\nIn mid-2025, after engaging and discussing with global regulatory authorities, we expect to commence a global registrational Phase 3 clinical trial of seralutinib for the treatment of patients with PH-ILD.\n\n\n\nOn May 6, Gossamer Bio and the Chiesi Group announced a development and co-commercialization collaboration for seralutinib. Gossamer and Chiesi will split global development costs for seralutinib, except for the PROSERA Study, for which Gossamer will remain solely responsible. In the United States, Gossamer and Chiesi will split profits and losses, and Chiesi will be solely responsible for commercialization of seralutinib outside of the United States, for which Gossamer will receive mid-to-high teens royalties.\n\n\n\nFinancial Results for Quarter Ended June 30, 2024\n\n\n\nCash, ...
