Information IACS-13909 IACS-13909 (BBP-398) is a specific and potent allosteric inhibitor of SHP2 (Src homology 2 domain-containing phosphatase) that suppresses signaling through the MAPK pathway. Targets SHP2 In vitro IACS-13909 is a specific and potent allosteric inhibitor of SHP2 that suppresses signaling through the MAPK pathway. IACS-13909 potently impedes proliferation of tumors harboring a broad spectrum of activated RTKs as the oncogenic driver. IACS-13909 potently suppresses tumor cell proliferation in vitro. In vivo In EGFR-mutant osimertinib-resistant NSCLC models with EGFR-dependent and EGFR-independent resistance mechanisms, IACS-13909, administered as a single agent or in combination with osimertinib, causes tumor regression in vivo.
