BBOT Reports Second Quarter 2026 Financial Results and Update on Corporate Progress
SOUTH SAN FRANCISCO, Calif., August 11, 2026 — BridgeBio Oncology Therapeutics, Inc. (“BBOT”) (Nasdaq: BBOT), a clinical-stage biopharmaceutical company focused on RAS-pathway malignancies, today reported financial results for the second quarter ended June 30, 2026, and provided a business update.
BBOT’s portfolio of RAS-pathway inhibitors is designed to enable direct dual inhibition of KRASG12C (BBO-8520), or KRASG12D/V (BBO-11818) in both its ON and OFF states as well as disruption of RAS-driven PI3Kα activation (BBO-10203) to achieve optimal target coverage of the most mutated driver oncogene in human cancer. Together, these assets uniquely position BBOT to achieve concurrent, high-level suppression of both the MAPK and PI3Kα pathways through a wholly-owned internal combination strategy.
“During the second quarter, we made meaningful progress in patient enrollment in our monotherapy and combination cohorts across each of our three clinical programs. Differentiated patient benefit in oncology is driven by optimal target coverage and the ability to combine with standard-of-care regimens. Therefore, we continue to focus heavily on advancing our combination development strategies,” said Pedro J. Beltran, Ph.D., Chief Executive Officer of BBOT. “In addition, our wholly-owned portfolio is uniquely positioned to enable concurrent suppression of the MAPK and PI3Kα pathways through internal combination strategies of each of our KRAS inhibitors with BBO-10203. We are excited to have both combinations already underway in patients. With multiple near-term clinical milestones across all programs expected in the second half of 2026 and cash runway into 2028, we believe we are well positioned to execute our strategy and expand treatment options for patients with mutant KRAS-driven cancers.”
Key Program Highlights and Updates
BBO-8520: An orally bioavailable small molecule direct inhibitor targeting both the ON and OFF states of KRAS G12C.
BBO-11818: An orally bioavailable small molecule pan-KRAS inhibitor that targets mutant KRAS in both the ON and OFF states.
BBO-10203: An orally bioavailable small molecule with a novel mechanism of action designed to block the physical interaction between RAS and PI3Kα, inhibiting RAS-driven PI3Kα-AKT signaling in tumors.
