Brief summary: The purpose of this research is to test if a combination treatment of nivolumab and relatlimab will result in tumor reduction in patients with metastatic uveal melanoma.

Detailed description: This is a phase II single-institution trial with a Simon two-stage minimax design with 27 patients (13 in stage 1, 14 in stage 2) setting a 5% type I error and 80% power under true objective response rate (ORR) of 20%. The null hypothesis (ORR=5%) is rejected if 4 or more responses are observed in 27 patients. No prior PD-1, CTLA-4 and/or LAG-3 blocking antibody treatment was allowed. We will also perform single-cell mRNA and T-cell receptor (TCR) variable, diversity, and joining (V\[D\]J) sequencing pre-treatment and at either progression or response.

Patients will be treated with nivolumab 480 mg/relatlimab 160 mg IV q4wks to progression or intolerable toxicity for up to two years.

Eligibility criteria: Inclusion Criteria:

1. Have a biopsy-proven diagnosis of metastatic uveal melanoma, previously untreated with anti-PD-1,Cytotoxic T lymphocyte antigen 4 (CTLA-4) and/or lymphocyte activation gene 3 (LAG-3) blocking antibodies.
2. Agree to undergo a pre-treatment and a post-treatment fresh biopsy of the tumor, if easily accessible and low-risk.
3. Have completed all previous therapy for a minimum of 3 weeks before the first dose of experimental treatment. All adverse events of previous therapy must have resolved. Palliative radiation therapy to a limited field is allowed within this 3 week period.

   * Coagulation:

     * International Normalized Ratio (INR) or Prothrombin Time (PT) ≤1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants.
     * Activated Partial Thromboplastin Time (aPTT) ≤1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants
     * Creatinine clearance should be calculated per institutional standard.
10. If a female of childbearing potential, have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
11. If a female of childbearing potential, be willing to use an adequate method of contraception as outlined in Section 5.8 Contraception, for the course of the study through 24 weeks after the last dose of study medication. Must abstain from ova donation for a minimum of 5 months after the end of treatment.

    Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.
12. If a male of childbearing potential, agree to use an adequate method of contraception as outlined in Section 5.8- Contraception, starting with the first dose of study therapy through 7 months after the last dose of study therapy. Must abstain from sperm donation for a minimum of 24 weeks after the end of treatment.

Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject

Exclusion Criteria:

2. Have a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment. Patients on replacement doses of corticosteroids and patients who received steroids as pre-medication to prevent an imaging contrast allergy are allowed.
3. Have a known history of active tuberculosis (Bacillus Tuberculosis)
4. Have had prior treatment with a PD-1 and/or LAG-3 targeted agent
5. Have hypersensitivity to nivolumab, relatlimab or any of their excipients.

7. Have had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 3 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from clinically significant adverse events due to a previously administered agent.

   * Note: Subjects with ≤ Grade 2 neuropathy are an exception to this criterion and may qualify for the study.
   * Note: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
