[{"type":"text","content":" SAN DIEGO--(BUSINESS WIRE)--\nGossamer 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 the addition of two CNS-penetrant Bruton’s tyrosine kinase (BTK) inhibitors to its product candidate pipeline.\n\nGossamer plans to initiate first-in-human studies of the first of these candidates, GB5121, in the fourth quarter of 2021. Gossamer intends to develop GB5121 in CNS-oncology indications, including relapsed / refractory primary CNS lymphoma (PCNSL), for which a potentially registrational Phase 1b / 2 study is expected to initiate in the first half of 2022.\n\nThe second product candidate, GB7208, is currently in IND-enabling studies and is expected to enter the clinic in the second half of 2022. In a BTK-dependent pre-clinical disease model, GB7208 demonstrated superior outcomes vs. tolebrutinib, a BTK inhibitor being studied in a broad Phase 3 program for multiple sclerosis (MS).\n\n“We are thrilled to be able to share our latest product candidates, the CNS-penetrant BTK inhibitors GB5121 and GB7208,” said Faheem Hasnain, Chairman, co-founder and CEO of Gossamer Bio. “These two promising product candidates are the result of intensive internal research, and we are excited to advance them into the clinic where there remains a high unmet need in treating malignant brain tumors and neurologic diseases.”\n\n“BTK inhibitors have emerged as an important class of treatment, particularly in oncology, but existing molecules have not been optimized for the treatment of central nervous system disorders,” said Laura Carter, Ph.D., Chief Scientific Officer of Gossamer Bio. “GB5121 and GB7208 were designed specifically with these disorders in mind, and in pre-clinical models, they have been shown to be potent, highly selective BTK inhibitors, with potentially best-in-class brain penetrance and target occupancy.”\n\nGB5121: Oral, CNS-Penetrant, Irreversible BTK Inhibitor for Treatment of PCNSL\n\n\nSuperior CNS penetration in preclinical models compared to other BTK inhibitors in development for oncology\n\n\nHighly selective for BTK, with no non-TEC kinases inhibited at greater than 50% in a broad kinome scan\n\n\nFirst-in-human Phase 1 clinical trial expected to initia...
