The number of participants experiencing dose-limiting toxicities (DLTs) to assess the overall safety and tolerability of BMS-986178 administered alone or in combination with Nivolumab and/or Ipilimumab in participants with advanced solid tumors. DLTs are defined based on the incidence, severity, and duration of adverse events (AEs) for which no clear alternative cause is identified. 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 drug and that does not necessarily have a causal relationship with this treatment.

The number of participants experiencing adverse events (AEs) to assess the overall safety and tolerability of BMS-986178 administered alone or in combination with Nivolumab and/or Ipilimumab in participants with advanced solid tumors. 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 drug and that does not necessarily have a causal relationship with this treatment.

The number of participants experiencing serious adverse events (SAEs) to assess the overall safety and tolerability of BMS-986178 administered alone or in combination with Nivolumab and/or Ipilimumab in participants with advanced solid tumors. A SAE is 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/incapacity, is a congenital anomaly/birth defect, and/or is an important medical event.

The number of participants experiencing adverse events (AEs) leading to discontinuation of study drug to assess the overall safety and tolerability of BMS-986178 administered alone or in combination with Nivolumab and/or Ipilimumab in participants with advanced solid tumors. 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 drug and that does not necessarily have a causal relationship with this treatment.

The number of deaths in each arm to assess the overall safety and tolerability of BMS-986178 administered alone or in combination with Nivolumab and/or Ipilimumab in participants with advanced solid tumors.

The number of participants with clinical laboratory test abnormalities to assess the overall safety and tolerability of BMS-986178 administered alone or in combination with Nivolumab and/or Ipilimumab in participants with advanced solid tumors. Results will be categorized according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03. Grade 1 = Mild Grade 2 = Moderate Grade 3 = Severe Grade 4 = Life Threatening Grade 5 = Death Related to AE Baseline is defined as the last non-missing measurement prior to the first dosing date and time
