SAN DIEGO--(BUSINESS WIRE)--Gossamer Bio, Inc. (Nasdaq: GOSS), a clinical-stage biopharmaceutical company focused on discovering, acquiring, developing and commercializing therapeutics in the disease areas of immunology, inflammation and oncology, today announced its financial results for the second quarter ended June 30, 2022 and provided a business update.

“Everyone at Gossamer is looking forward to the upcoming TORREY Phase 2 results, as we actively prepare for seralutinib’s next steps in clinical development,” said Faheem Hasnain, Chairman, Co-Founder and CEO of Gossamer.

“Our strong financial position, bolstered by our recent private placement, has enabled us to accelerate investment into a registrational Phase 3 program for seralutinib. Despite existing treatments that improve symptoms of the disease, PAH remains a progressive illness, with a heavy burden on patients and caregivers. Seralutinib is one of the few therapies in development with the potential to directly address the pathology of the underlying disease, underscoring the need to accelerate seralutinib’s registrational Phase 3 program.”
