BMS-986523 alone and with other cancer medicines for advanced KRAS-altered solid tumors

A Phase 1/2a, Open-Label, Multicenter Study to Assess the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Preliminary Efficacy of BMS-986523 As Monotherapy and in Combination With Anti-Cancer Agents in Participants With Advanced Solid Malignancies

Phase1; Phase2 Interventional Bristol-Myers Squibb · NCT07223047

This treatment tests whether BMS-986523, alone or combined with chemotherapy or immunotherapy, helps people with advanced KRAS-altered lung, colorectal, or pancreatic cancers.

What this trial studies

Bristol-Myers Squibb is running a phase 1/2 program of the investigational agent BMS-986523 given alone or together with agents such as gemcitabine, nab‑paclitaxel, cetuximab, or pembrolizumab in adults with unresectable or metastatic solid tumors that have KRAS alterations. Phase 1 focuses on safety, tolerability, and dose-finding while phase 2 explores preliminary anti-tumor activity across disease-specific arms including NSCLC, CRC, and PDAC, with one arm requiring PD-L1 ≥50%. Key outcomes include adverse events, tolerability, and measures of tumor response and disease control. Eligible participants must have a confirmed KRAS mutation or amplification and have received, be ineligible for, or decline standard treatments.

Who should consider this trial

Good fit: Adults with unresectable or metastatic NSCLC, colorectal cancer, or pancreatic ductal adenocarcinoma who have a confirmed KRAS alteration and who have received, are ineligible for, or decline standard therapies (with PD-L1 ≥50% required for one arm).

Not a fit: Patients with untreated central nervous system metastases, active interstitial lung disease or recent other malignancies, or those without a KRAS alteration are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this approach could offer a new targeted treatment option for patients with KRAS-altered advanced solid tumors and potentially improve response rates or survival.

How similar studies have performed: Related targeted and combination approaches have shown benefit in certain KRAS-selected groups (for example KRAS G12C inhibitors), but BMS-986523 is investigational and its effectiveness across KRAS alterations remains exploratory.

Eligibility criteria

Inclusion Criteria

* Participants must have a histologically confirmed diagnosis of a locally advanced and unresectable or metastatic solid tumor malignancy with a known Kirsten rat sarcoma viral oncogene homolog (KRAS) alteration (mutation or amplification).
* Participants must, for Arm D, have a PD-L1 expression (≥50%).
* Participants must have previously received, be ineligible for, or decline (after having been provided adequate information to make an informed decision) the protocol defined standard of care (SoC) treatments.

Exclusion Criteria

* Participants must not have untreated central nervous system (CNS) metastases.
* Participants must not have concurrent malignancy (present during screening) requiring treatment or history of prior malignancy active within 2 years prior to treatment.
* Participants must not have a history of, or any evidence of, interstitial lung disease or active, non-infectious pneumonitis. A history of radiation pneumonitis in the radiation field is permitted.
* Participants must not have a history of prior severe cutaneous adverse reactions (SCARs), including Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN).
* Other protocol-defined Inclusion/Exclusion criteria apply.
