This study is assessing how safe and tolerable a new drug (called BMS-986360) is when given alone and in combination with chemotherapy or immunotherapy in people with advanced solid cancersA Phase 1, Open-label, Multicenter Study of BMS-986360/CC-90001 Alone and in Combination With Chemotherapy or Nivolumab in Advanced Solid Tumors

Exclusion

• Participants with primary central nervous system (CNS) disease, or tumors with CNS metastases as the only disease site, will be excluded. Participants with controlled brain metastases, however, will be allowed to enroll. Controlled brain metastases are defined as no radiographic progression for at least 4 weeks following radiation and/or surgical treatment (or 4 weeks of observation if no intervention is clinically indicated), no longer taking steroids for at least 2 weeks prior to first dose of study intervention, and with no new or progressive neurological signs and symptoms.
• Participants with a condition requiring systemic treatment with corticosteroids (> 10 mg daily prednisone equivalent) within 14 days or other immunosuppressive medications within 30 days of randomization. Inhaled or topical steroids and adrenal replacement steroid doses > 10 mg daily prednisone equivalent are permitted in the absence of active autoimmune disease.
• Participants with concurrent malignancy or history of prior malignancy active within 2 years (except history of early-stage basal/squamous cell skin cancer or non-invasive or in situ cancers who have undergone definitive treatment) are excluded unless treatment was completed at least 2 years before randomization and the participant has no evidence of disease.
• Participants with NSCLC with known or not tested for epidermal growth factor receptor (EGFR) or V-raf murine sarcoma viral oncogene homolog B1 (BRAF) V600E mutations, or anaplastic lymphoma kinase (ALK) or receptor tyrosine kinase (ROS1) translocations sensitive to available targeted inhibitor therapy

Other protocol-defined inclusion/exclusion criteria apply.
