If TnT levels are between >1 to 2 × ULN within 24 hours, the participant may undergo a cardiac consultation and be considered for treatment, following cardiologist recommendation. When repeat levels within 24 hours are not available, a repeat test should be conducted as soon as possible. If TnT repeat levels beyond 24 hours are < 2 × ULN, the participant may undergo a cardiac consultation and be considered for treatment, following cardiologist recommendation. Notification of the decision to enroll the participant following cardiologist recommendation has to be made to the BMS Medical Monitor or designee.\n- Relatlimab-specifik exclusion criteria:Left ventricular ejection fraction (LVEF) assessment with documented LVEF < 50% by either transthoracic echocardiogram (TTE) or multigated acquisition (MUGA) scan (TTE preferred test) within 6 months prior to start of study treatment.\n- Brain metastases (based on symptoms)\n- Non-clear cell RCC\n- No measurable lesion according to RECIST 1.1\n- Subjects with any active autoimmune disease or a documented history of autoimmune disease, or history of syndrome that required systemic steroids or immunosuppressive medications, except for subjects with vitiligo or resolved childhood asthma/atopy\n- Prior CTLA-4 or PD-1/PD-L1 or LAG-3 targeting immunotherapy\n- Radiotherapy prior or post-surgery\n- Patients will be excluded if they test positive for hepatitis B virus surface antigen (HBV sAg) or hepatitis C virus ribonucleic acid (HCV antibody), indicating acute or chronic infection; if treated and being at least one year free from HCV patients are allowed to participate\n- Patients will be excluded if they have known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS)"}
