BBOT Presents Preclinical Data Demonstrating Potential of BBO-11818 as a Potent panKRAS Inhibitor at the 2025 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics
Data demonstrate potent suppression of MAPK signaling and viability in KRAS mutant cell lines, as well as anti-tumor activity across multiple KRASG12D and KRASG12V cell-derived xenograft (CDX) models BBO-11818's selectivity for KRAS demonstrated by its >1000-fold lower potency against NRAS, HRAS, and BRAF-mutant cell lines Efficacy of the combination with BBOT's RAS:PI3K ⍺ breaker, BBO-10203, is driven by a robust decrease in tumor cell proliferation and increase in apoptosis; combination benefit also observed with cetuximab and anti-PD-1 treatment BBO-11818 is currently being evaluated in the Phase 1 KONQUER-101 trial in patients with KRAS mutant pancreatic, non-small cell lung, and colorectal cancer with initial Phase 1 clinical data expected in the second half of 2026 SOUTH SAN FRANCISCO, Calif., Oct. 23, 2025 (GLOBE NEWSWIRE) -- BridgeBio Oncology Therapeutics, Inc. (“BBOT”) (Nasdaq: BBOT), a clinical-stage biopharmaceutical company focused on RAS-pathway malignancies, today announced new preclinical data on BBO-11818 demonstrating its potential as a potent panKRAS inhibitor targeting mutant KRAS in both the ON (active GTP-bound) and OFF (inactive GDP-bound) states, with selectivity over HRAS and NRAS.
