For the quarter ended September 30, 2026, net loss was $34.2 million, compared with $44.8 million a year earlier. Research and development expense was $29.6 million versus $35.1 million, and general and administrative expense was $7.9 million versus $14.1 million; the prior-year G&A figure included a $7.8 million charge related to common stock issuable to BridgeBio Pharma.

In inhibitor-naïve NSCLC, BBO-8520 monotherapy showed a 63% response rate and 100% disease control rate. Combination cohorts for BBO-11818 and BBO-10203 are enrolling in colorectal and pancreatic cancers; monotherapy data updates are expected in the fourth quarter of 2026.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Disease control rate 100% BBO-8520 monotherapy in inhibitor-naïve NSCLC patients; 41/41
objective response rate (ORR) medical
"showed an objective response rate (ORR) of 75%"
The objective response rate (ORR) is the percentage of patients in a clinical trial whose tumors shrink by a pre-set amount for a minimum time, counting both complete disappearance and meaningful partial shrinkage. Investors watch ORR because it gives an early, quantitative signal that a treatment is having a direct effect on disease—like the percent of people whose fever drops after taking a medicine—which can influence expectations for later trial success, regulatory approval, and market potential.
disease control rate (DCR) medical
"a disease control rate (DCR) of 100%"
The disease control rate (DCR) is the share of patients in a clinical trial whose cancer either shrinks, disappears, or does not get worse for a predefined period after treatment. For investors, DCR is a practical measure of a drug’s ability to halt disease progression — akin to counting how many cars in a fleet are kept running or fixed after a repair — and can influence a therapy’s regulatory prospects, market potential, and perceived risk.
KRASG12C inhibitor-experienced medical
"in 2L+ KRASG12C inhibitor-experienced NSCLC patients"
pan-KRAS inhibitor medical
"an orally bioavailable small molecule pan-KRAS inhibitor"
A pan-KRAS inhibitor is a drug designed to block multiple common mutant forms of the KRAS protein, which can drive cancer cell growth. Investors care because such drugs can potentially treat a broader group of tumors with KRAS mutations—like a single adapter that fits several broken machines—so clinical success could open a larger market but also carries typical drug-development and regulatory risks.

BBOT Reports Third Quarter 2026 Financial Results and Update on Corporate Progress

 

•
BBO-8520 plus pembrolizumab demonstrated a 75% ORR at 500 mg QD and 53% ORR across dose levels in 2L+ KRASG12C inhibitor-experienced NSCLC patients
•
BBO-11818 and BBO-10203 combination cohorts enrolling in KRAS-mutant colorectal cancer (CRC) and pancreatic ductal adenocarcinoma (PDAC); BBO-11818 and BBO-10203 monotherapy data update expected in the fourth quarter of 2026
•
Cash runway expected to fund operations into 2029

 

SOUTH SAN FRANCISCO, Calif., November 10, 2026 — BridgeBio Oncology Therapeutics, Inc. (“BBOT”) (Nasdaq: BBOT), a clinical-stage biopharmaceutical company focused on RAS-pathway malignancies, today reported financial results for the quarter ended September 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 their 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.

 

“The third quarter was an important period for BBOT as we reported updated clinical data for BBO-8520 and delineated our strategic focus. Driven by encouraging clinical data across all three programs we are executing on multiple combinations with the potential for significant patient benefit,” said Pedro J. Beltran, Ph.D., Chief Executive Officer of BBOT. “With a strong balance sheet, multiple data catalysts expected through mid-2027, and cash runway into 2029, we believe BBOT is well positioned to advance differentiated therapies for patients with 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 KRASG12C.

 

•
In September 2026, BBOT announced new data from the ongoing ONKORAS-101 (NCT06343402) Phase 1 study. BBO-8520 in combination with pembrolizumab in KRASG12C inhibitor-experienced NSCLC patients showed an objective response rate (ORR) of 75% at the 500 mg once-daily (QD) dose level and 53% across all dose levels (N=17), with a generally tolerable and manageable safety profile. Adverse events were primarily gastrointestinal (GI)-related, and a favorable liver safety profile was observed. We believe this data positions BBOT to address a new G12Ci-experienced patient population created by G12C OFF-only inhibitors in combination with pembrolizumab in 1L KRASG12C positive NSCLC.
•
BBO-8520 monotherapy in 2L+ KRASG12C inhibitor-naïve NSCLC patients showed an ORR of 63% (26/41) and a disease control rate (DCR) of 100% (41/41). Among 28 patients eligible for a six-month follow-up, 75% (21/28) remained on treatment beyond six months. The safety profile was tolerable and manageable, with no grade 3 or higher liver enzyme elevations.

 

BBO-11818: An orally bioavailable small molecule pan-KRAS inhibitor that targets KRAS in both the ON and OFF states.

 

•
Initiated dosing of BBO-11818 in combination with BBO-10203 as well as in combination with cetuximab in CRC and PDAC.
•
Monotherapy data update expected in the fourth quarter of 2026

 

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.

 

•
Prioritized BBO-10203 in internal combinations with BBO-11818 and in combination with standard-of-care agents in KRAS-mutant cancers; combination cohorts are enrolling in CRC and PDAC.
•
Monotherapy data update expected in the fourth quarter of 2026.

 

 


 

Third Quarter 2026 Financial Results

 

•
Cash Position: As of September 30, 2026, BBOT had cash, cash equivalents and marketable securities totaling $315.3 million, which is expected to provide cash runway into 2029.
•
Research and development (R&D) expenses: R&D expenses were $29.6 million for the third quarter of 2026 compared to $35.1 million for the third quarter of 2025. The decrease in R&D expense was primarily driven by a decrease in clinical stage program related expenses.
•
General and administrative (G&A) expenses: G&A expenses were $7.9 million for the third quarter of 2026 compared to $14.1 million for the third quarter of 2025. The decrease in G&A expense reflects a decrease in payroll and personnel-related expenses primarily due to a $7.8 million charge recognized in the third quarter of 2025 related to common stock issuable to BridgeBio Pharma, partially offset by an increase in legal and other business expenses.
•
Net Loss: Net loss was $34.2 million for the third quarter of 2026 compared to $44.8 million for the third quarter of 2025.
