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 topline results from its Phase 2b LEDA trial in patients with moderate-to-severe eosinophilic asthma and its Phase 2 TITAN trial in patients with chronic rhinosinusitis.

"While we did not achieve statistical significance on the primary endpoint in the LEDA Study, we are encouraged by the consistent results observed for all three doses of once-daily, oral GB001 therapy across the primary and secondary endpoints," said Sheila Gujrathi, M.D., Co-Founder and Chief Executive Officer of Gossamer. "We believe these data provide important information for designing a well-powered Phase 3 program for GB001 in severe asthma. We plan to engage in global regulatory discussions in order to inform our thinking around potential partnerships or strategic alternatives for this program."

"The results of the robust LEDA Study are meaningful and help us to further understand the DP2 pathway in asthma," said Bruce Levy, M.D., Chief, Division of Pulmonary and Critical Care Medicine at Brigham and Women's Hospital and Professor of Medicine at Harvard Medical School. "I believe GB001 as an oral treatment has the potential to serve the high unmet need of patients with uncontrolled severe asthma."
