Model BBP-398 - SHP2 Inhibitor for RTK Cancers

BridgeBio is developing SHP2 inhibitors as potentially effective additions to the therapeutic arsenal for difficult-to-treat cancers. SHP2, encoded by the PTPN11 gene, links growth factor signaling with the downstream RAS/ERK/MAPK pathway to regulate cell growth and division. Over-activity of this pathway, often driven by distinct gene mutations, causes or contributes to many human cancers. Inhibiting SHP2 offers a new approach to treat tumors relying on this pathway. SHP2 also suppresses T-cell activity against growing tumors through regulation of the adaptive immune response. SHP2 inhibition may relieve this negative effect, enhancing the patient`s immune response to fight cancer proliferation. A Phase 1 clinical trial is planned (NCT04528836).
