BridgeBio Oncology Therapeutics (Nasdaq: BBOT) announced late-breaking preclinical data on BBO-10203 at SABCS on Dec 10, 2025. Data show BBO-10203 is a first-in-class covalent RAS:PI3Kα breaker that binds PI3Kα at Cys242, blocks RAS-driven PI3Kα-AKT signaling, and produces dose- and time-dependent pAKT inhibition after oral dosing without inducing hyperglycemia in glucose tolerance testing.
BBO-10203 demonstrated robust anti-tumor activity as monotherapy and combined with fulvestrant, ribociclib, trastuzumab or chemotherapy in preclinical breast cancer models. A Phase 1 trial (BREAKER-101; NCT06625775) is enrolling with initial Phase 1 data expected in first half of 2026.

BridgeBio Oncology Therapeutics (Nasdaq: BBOT) announced two poster presentations at the San Antonio Breast Cancer Symposium (SABCS), Dec 9-12, 2025, in San Antonio, Texas. Both posters feature BBO-10203, described as a first-in-class, orally bioavailable, selective breaker of the RAS:PI3Kα interaction.
Details: a Late-Breaking Pre-clinical poster (Abstract 3568, Presentation PS2-12-06) on Dec 10, 5:00–6:30 p.m. CT by Kerstin Sinkevicius, PhD, reports tumor growth inhibition alone and combined with fulvestrant or ribociclib without inducing hyperglycemia. A Trials-in-Progress poster (Abstract 203, Presentation PS5-07-06) on Dec 12, 12:30–2:00 p.m. CT by Andreas Varkaris, MD, PhD, outlines the phase 1a/1b BREAKER-101 study of BBO-10203 in advanced solid tumors.
BridgeBio Oncology Therapeutics (Nasdaq: BBOT) reported preclinical data showing BBO-10203 selectively breaks the RAS:PI3Kα interaction, covalently binding PI3Kα at cysteine 242 and inhibiting RAS-driven PI3Kα-AKT signaling without inducing hyperglycemia or hyperinsulinemia in glucose tolerance testing.
In vivo studies showed oral bioavailability, complete target engagement at low nanomolar levels, robust monotherapy anti-tumor activity across KRAS-mutant CDX, PDX and GEM models, and deep tumor regressions when combined with BBOT’s KRAS inhibitors BBO-8520 and BBO-11818 at well-tolerated doses. Phase 1 BREAKER-101 is enrolling; initial Phase 1 clinical data expected in H1 2026.
BridgeBio Oncology Therapeutics (Nasdaq: BBOT) presented preclinical data on BBO-11818 at the 2025 AACR‑NCI‑EORTC conference showing potent pan‑KRAS activity in KRASG12D and KRASG12V models.
Key findings: single‑digit nanomolar EC50s for ERK inhibition and proliferation in KRAS mutant cell lines; >1000‑fold lower potency versus NRAS, HRAS, and BRAF‑mutant lines; oral bioavailability and favorable PK with dose‑dependent pERK inhibition in vivo; tumor regressions in multiple CDX models; combination benefits with BBO‑10203, cetuximab, and anti‑PD‑1 including complete regressions in a KRASG12D syngeneic model. Phase 1 KONQUER‑101 is ongoing with initial clinical data expected in H2 2026.
