WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with study drugs plus an additional 165 days (approximately 24 weeks) after the last dose of nivolumab and/or relatlimab. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately.

• Patient understands the study regimen, its requirements, risks and discomforts and is able and willing to sign the informed consent form in accordance with regulatory and institutional guidelines must be obtained before the performance of any protocol related procedures that are not part of normal patient care. Subjects must be competent to report adverse events (AEs), understand the drug dosing schedule and use of medications to control AEs

Exclusion Criteria

• Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 1 week prior to initiation of study treatment. This is not applicable to patients with primary brain tumors.
• Patient is expected to require any other form of systemic or localized antineoplastic therapy while on study
• Patients with a history of prior treatment with anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CTLA4, or anti-Lag-3 antibodies
• Any of the following procedures or medications: * Within 2 weeks prior to initiation of study treatment: ** Systemic or topical corticosteroids at immunosuppressive doses (> 10 mg/day of prednisone or equivalent). Inhaled or topical steroids, and adrenal replacement steroid doses =< 10 mg daily prednisone equivalent, are permitted in the absence of active autoimmune disease ** Palliative radiation or gamma knife radiosurgery ** Chemotherapy * Within 4 weeks prior to initiation of study treatment: ** Any investigational cytotoxic drug. Exposure to any non-cytotoxic drug within 4 weeks or 5 half-lives (whichever is shorter) is prohibited. If 5 half-lives is shorter than 4 weeks, agreement with investigational new drug (IND) sponsor is mandatory ** Non-oncology vaccines containing live virus ** Allergen hyposensitization therapy ** Growth factors, e.g. granulocyte-colony stimulating factor (G-CSF), granulocyte macrophage-colony stimulating factor (GM-CSF), erythropoietin ** Major surgery
• History of severe hypersensitivity reaction to any monoclonal antibodies or related compounds or to any of their components (e.g., history of severe hypersensitivity reactions to drugs formulated with polysorbate 80)

• Has an active known or suspected autoimmune disease. Subjects with type I diabetes mellitus, hypothyroidism only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll
• Has a diagnosis of immunodeficiency
• Prior tissue or organ allograft or allogeneic bone marrow transplantation. Exceptions can be approved by the IND sponsor if loss of the graft is not a clinical concern
• A known or underlying medical condition that, in the opinion of the investigator, could make the administration of study drug hazardous to the subject or could adversely affect the ability of the subject to comply with or tolerate study

• Troponin T (TnT) or I (TnI) > 2 x ULN. Subjects with TnT or TnI levels between > 1 to 2 x ULN will be permitted if repeat levels within 24 hours are =< 1 x ULN. If TnT or TnI levels are > 1 to 2 x ULN within 24 hours, the subjects may undergo a cardiac evaluation and be considered for treatment, following a discussion with the IND Sponsor. When repeat levels within 24 hours are not available, a repeat test should be conducted as soon as possible. If TnT or TnI repeat levels beyond 24 hours are < 2 x ULN, the subject may undergo cardiac evaluation and be considered for treatment, following discussion with the IND sponsor
