What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Part 1: Number of Participants With Dose Limiting Toxicity (DLTs)

    A DLT was defined as:

    • Death not related to disease progression
    • Grade (Gr) 4 (Life-threatening) neurotoxicity
    • Gr 3 (Severe) neurotoxicity of greater than 7 days
    • Gr 3 neurotoxicity does not revert to baseline within 28 days of the start date of the Grade 3 event
    • Seizures of grade that do not resolve within 7 days
    • Gr 4 cytokine release syndrome (CRS) that does not resolve to less than or equal to Gr 3 within 3 days
    • Gr 3 CRS that does not resolve to less than or equal to Grade 2 within 7 days
    • Any increase in aspartate aminotransferase (AST) or ALT \> 3 Ã- ULN and concurrent increase in total bilirubin \> 2 Ã- ULN that is unrelated to CRS and has no other probable reason to explain the combination of increases
    • Any other Gr 3 or 4 event deemed unexpected by the Investigator and considered a DLT upon evaluation by the safety review committee

    Measured: Cycle 1 (Each cycle consist of 28 days)

  2. Part 1: Number of Participants With Adverse Events (AEs)

    An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a preexisting medical condition in a clinical investigation participant administered study treatment and that does not necessarily have a causal relationship with this treatment.

    Measured: From first dose until 100 days after last dose (Up to approximately 5 months)

  3. Part 1: Number of Participants With Serious Adverse Events (SAEs)

    A SAE is defined as any untoward medical occurrence that, at any dose: results in death, is life-threatening, requires inpatient hospitalization or causes prolongation of existing hospitalization, results in persistent or significant disability or permanent damage, is a congenital anomaly/birth defect, is an important medical event.

    Measured: From first dose until 30 days after last dose (Up to approximately 3 months)

  4. Part 1: Number of Participants With AEs Leading to Discontinuation

    An Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of a preexisting medical condition in a clinical investigation participant administered study treatment and that does not necessarily have a causal relationship with this treatmen

    Measured: From first dose until 30 days after last dose (Up to approximately 3 months)

  5. Part 1: Number of Participants Who Died

    Death due to any cause was assessed.

    Measured: From first dose until 100 days after last dose (Up to approximately 5 months)

  6. Part 2 Objective Response Rate (ORR) Assessed by Blinded Independent Central Review (BICR) as Per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1

    Objective Response Rate (ORR) is defined as the percentage of participants with a confirmed Best overall response of Complete Response (CR) or Partial Response (PR) by RECIST v1.1.

    Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \< 10 mm.

    Partial Response (PR): At least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters.

    Measured: From randomization untill disease progression or death, whichever occurs first (up to approximately 5 months)

Secondary outcomes (12)
  1. Part 1: Maximum Observed Plasma Concentration (Cmax)

    Blood samples were collected to assess adequate PK profiles. Participants were not enrolled in Part 1a, 1b.

    Measured: Cycle 1 Day 1 (Each cycle consist of 28 days)

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing BMS-986466, Adagrasib and Cetuximab in people with Advanced Solid Tumors, run by Bristol-Myers Squibb at 9 sites in 5 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 22 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States, Israel, Australia, Finland, France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 22 Jul 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Part 1: Number of Participants With Dose Limiting Toxicity (DLTs) (time frame: Cycle 1 (Each cycle consist of 28 days)). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Jul 2025.
