New preclinical research from The University of Texas MD Anderson Cancer Center and BridgeBio Pharma, Inc. affiliate Navire Pharma, Inc., finds that the novel SHP2 inhibitor IACS-13909 is able to overcome multiple therapeutic-resistance mechanisms in non-small cell lung cancer (NSCLC), suggesting a possible new approach to treating cancers that have developed resistance to the targeted EGFR inhibitor osimertinib.

The data is published today in Cancer Research, a journal of the American Association for Cancer Research. IACS-13909, is a potent and selective allosteric SHP2 (Src homology 2 domain-containing phosphatase) inhibitor developed through collaboration between Navire and MD Anderson’s Therapeutics Discovery division. Based on these data, Navire plans to launch a clinical study of SHP2 inhibitors by the end of 2020 at multiple US sites, including MD Anderson.

“Our findings show that IACS-13909 is capable of suppressing tumor cell proliferation in vitro and causing tumor regression in vivo for lung cancers harboring a variety of activated kinases as the oncogenic driver,” said lead author Yuting Sun, Ph.D., co-project lead and senior research scientist with TRACTION at MD Anderson. “These data suggest that targeting SHP2 could provide a viable strategy for overcoming osimertinib resistance occurring through a variety of mechanisms.”  Read more.
