A Phase 1/2 Study of BMS-986408 Alone and in Combination With Nivolumab or With Nivolumab and Ipilimumab in Participants With Advanced Solid Tumors

Number of Participants With Dose Limiting Toxicities (DLTs)

时间窗: From first dose (Day 1) till 28 days

A Dose-Limiting Toxicity (DLT) is defined as a treatment-related adverse event that meets specific severity criteria, excluding those clearly due to disease progression or unrelated causes. DLTs include: any Grade ≥3 non-hematologic toxicity (with exceptions like transient nausea, fatigue, rash, or electrolyte imbalances), significant liver enzyme elevations, Grade 4 neutropenia \>7 days, Grade 4 thrombocytopenia, Grade 3 thrombocytopenia with bleeding, febrile neutropenia, and any Grade ≥3 immune-mediated toxicity including myocarditis, myelitis, or severe skin reactions. Grade 3 is severe or medically significant but not immediately life-threatening; Grade 4 events are usually severe enough to require hospitalization.

Number of Participants With Adverse Events

时间窗: From first dose (Day 1) till 30 days after the last dose (Up to approximately 13 months) for Group A to C and from Day 1 untill 100 days after last dose (up to approximately 15 months) for group D

An adverse event (AE) is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition occurring in a clinical investigation participant after signing of informed consent, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (such as an abnormal laboratory test result), symptom, or disease temporally associated with the study intervention. Serious Adverse Event (SAE) is defined as any untoward medical occurrence that, at any dose results in death, is life-threatening, and requires inpatient hospitalization or causes prolongation of existing hospitalization.

Number of Participants Who Died

时间窗: From first dose (Day 1) until 100 days after the last dose (Up to approximately 15 months)
