BBOT Reports Second Quarter 2026 Financial Results and Update on Corporate Progress
Rhea-AI Summary
BridgeBio Oncology Therapeutics (Nasdaq: BBOT) reported second quarter 2026 results and clinical progress for its RAS-pathway pipeline targeting KRAS and PI3Kα malignancies. As of June 30, 2026, BBOT held $344.1 million in cash, cash equivalents and marketable securities, which the company expects will fund operations into 2028.
During the quarter, BBOT advanced monotherapy and combination cohorts for all three lead programs. It continued enrolling the BBO-8520 plus pembrolizumab NSCLC cohort and initiated a BBO-8520 plus BBO-10203 combination in KRASG12C NSCLC. For BBO-11818, BBOT continued monotherapy dose escalation, began dosing in combination with cetuximab, and after quarter-end initiated a combination with BBO-10203. At AACR, BBOT presented preclinical data showing potent activity of BBO-11818 in KRASG12D/V models, strong combination effects with cetuximab or BBO-10203, and complete tumor regressions when combined with anti–PD-1 in models.
BBO-10203 combination cohorts in HR+ breast cancer, HER2+/HR− breast cancer and colorectal cancer remained open for enrollment, supported by preclinical data demonstrating strong in vivo combination effects with tucatinib or trastuzumab in HER2-amplified models. Second quarter 2026 research and development expenses rose to $49.2 million from $27.4 million a year earlier, while general and administrative expenses increased to $11.0 million from $2.7 million, reflecting standalone operations, a de-SPAC transaction and one-time severance. Net loss widened to $56.5 million compared to $28.4 million in the prior-year quarter. On the balance sheet, BBOT reported total assets of $376.7 million, total liabilities of $53.6 million and stockholders’ equity of $323.1 million as of June 30, 2026.

SOUTH SAN FRANCISCO, Calif., Aug. 11, 2026 (GLOBE NEWSWIRE) -- 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.”
