BridgeBio Pharma and Affiliate Navire Pharma Announce Dosing of First Patient in Phase 1 Clinical Trial of SHP2 inhibitor BBP-398 for Tumors Driven by RAS and Receptor Tyrosine Kinase Mutations

SAN FRANCISCO, Nov. 13, 2020 (GLOBE NEWSWIRE) -- BridgeBio LLC. (Nasdaq: BBIO) and affiliate Navire Pharma, Inc. announced today that the first patient has been dosed in a Phase 1 clinical trial of its SHP2 inhibitor (BBP-398) in patients with solid tumors driven by mutations in the MAPK signaling pathway, including RAS and receptor tyrosine kinase genes. BBP-398 was developed through a collaboration with The University of Texas MD Anderson Cancer Center’s Therapeutics Discovery division.

In this two-part Phase 1 study, safety and preliminary anti-tumor activity will be examined. Part 1 is a dose escalation to establish the recommended Phase 2 dose (RP2D) of BBP-398. Part 2 will examine preliminary anti-tumor activity in four cohorts of patients with certain molecular alterations. Those cohorts include advanced KRAS G12C mutant non-small cell lung carcinoma (NSCLC), advanced KRAS G12C mutant non-NSCLC, advanced solid tumors with other MAPK pathway mutations and advanced EGFR-mutant NSCLC. David S. Hong, professor of Investigational Cancer Therapeutics at MD Anderson, will serve as the lead principal investigator for the study.

The primary objective of the study is to evaluate the safety of BBP-398 in advanced cancer patients, with secondary objectives assessing preliminary anti-tumor activity, including objective response rates and duration of response. Patients enrolling in the study must have a diagnosis of advanced (primary or recurrent) or metastatic solid tumor with potentially susceptible genomic alterations in the MAPK pathway (excluding BRAF V600X).

“SHP2 inhibitors have the potential to be effective additions to the therapeutic arsenal for difficult-to-treat cancers by overcoming multiple mechanisms that tumors use to evade treatments,” said Eli Wallace, Ph.D., chief scientific officer of oncology at BridgeBio, Navire’s parent company. “This study is a critical step in understanding the potential that BBP-398 has for patients with tumors driven by RAS or other MAPK-pathway activating mutations and informing our future clinical development activities.”

SHP2, a conserved protein tyrosine phosphatase, plays a critical role in cell signaling and growth, which are important in the progression of cancer. As SHP2 regulates receptor tyrosine kinase signaling pathways commonly overly activated in cancer, targeting SHP2 may offer a potential new approach to treat this disease.

BBP-398 was initially discovered and developed by a team of scientists in MD Anderson’s Institute for Applied Cancer Science (IACS) and Translational Research to Advance Therapeutics and Innovation in Oncology (TRACTION) platforms, both engines within the Therapeutics Discovery division. The ongoing research is supported by Navire through a global licensing and development agreement with MD Anderson.
