• At least 18 years of age.

• ECOG performance status ≤ 1.

• Normal bone marrow and organ function as defined below:

  • Absolute neutrophil count ≥ 1,500/µL
  • Platelets ≥ 100,000/µL
  • Hemoglobin ≥ 9.0 g/dL
  • Total bilirubin ≤ 2.0 x IULN (except participants with Gilbert's syndrome who must have total bilirubin < 3.0 mg/dL)
  • AST(SGOT)/ALT(SGPT) ≤ 2.5 x IULN without hepatic metastasis and ≤ 5.0 x IULN with hepatic metastasis
  • Creatinine ≤2 x ULN or Creatinine clearance calculated by Cockcroft-Gault formula ≥45 ml/min

• Patients with brain or meningeal metastases are eligible provided they meet the following criteria:

  • No evidence of progression by neurologic symptoms or signs for at least 4 weeks prior to first dose of study treatment
  • Metastatic brain lesions that do not require immediate intervention
  • No use of corticosteroids with dose above 10 mg prednisone (or equivalent)

• The effects of the study drugs on the developing human fetus are unknown. For this reason, women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry, for the duration of study participation, and for 100 days after completion of study treatment. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately. Men treated or enrolled on this protocol must also agree to use adequate contraception prior to the study, for the duration of the study, and 100 days after completion of study treatment.

• Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable).

Exclusion Criteria:

• A history of other malignancy with the exception of:

  • Malignancies for which all treatment was completed at least 2 years before registration and the patient has no evidence of disease.
  • Carcinoma of the skin without melanomatous features.

• Patients with actionable EGFR mutation, ALK rearrangement, ROS1 fusion or RET fusion are excluded from the study.

• Currently receiving any other investigational agents or having received any investigational agents within 28 days or 5 half-lives of first dose of trial treatment.

• A history of allergic reactions attributed to compounds of similar chemical or biologic composition to zimberelimab, domvanalimab, etrumadenant, or other agents used in the study. Known hypersensitivity to recombinant proteins or any excipient contained in the trial formulations.

• Use of any live vaccines against infectious diseases within 28 days of first dose of trial treatment.

• Any gastrointestinal condition that would preclude the use of oral medications (e.g. difficulty swallowing, nausea, vomiting, or malabsorption).

• History of trauma or major surgery within 28 days prior to the first dose of study treatment.

• Underlying medical conditions that in the investigator's opinion will make the administration of study treatment hazardous, including but not limited to:

  • Interstitial lung disease, including history of interstitial lung disease or noninfectious pneumonitis
  • Active viral, bacterial or fungal infection requiring parenteral treatment within 14 days of the initiation of study treatment
  • Clinically significant cardiovascular disease
  • A condition that may obscure the interpretation of toxicity determination or AEs
  • History of prior solid organ transplantation

• Concurrent medical condition requiring the use of supra-physiologic doses of corticosteroids (> 10 mg/day of oral prednisone or equivalent) or immunosuppressive medications (with the exception of absorbable topical corticosteroids).

• Positive test results for hepatitis B surface antigen, hepatitis C virus antibody, hepatitis C qualitative RNA, or human immunodeficiency virus-1 antibody at screening.

• Known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.

• Any active autoimmune disease or documented history of autoimmune disease or syndrome that required systemic treatment in the past 2 years (i.e. with use of disease-modifying agents, corticosteroids, or immunosuppressive drugs) except for vitiligo or resolved childhood asthma/atopy.

  • Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment
  • Participants with asthma who require intermittent use of bronchodilators, inhaled corticosteroids, or local corticosteroid injections will not be excluded from this study. Participants on chronic systemic corticosteroids will be excluded.

• Pregnant and/or breastfeeding. Women of childbearing potential must have a negative pregnancy test within 14 days of study entry.

• Due to the potential risk for drug-drug interactions with etrumadenant, participants must not have had:

  • Oral treatment with strong inhibitors of breast cancer resistance protein (BCRP) (e.g., cyclosporin A, eltrombopag) or BRCP substrates with a narrow therapeutic window, administered orally (e.g., prazosin, rosuvastatin) within 4 weeks or 5 drug-elimination half-lives of the drug (whichever is longer) prior to initiation of study treatment.

  • Oral treatment with strong inhibitors of P-glycoprotein (P-gp) substrates (e.g., itraconazole, quinidine, verapamil, dronedarone, ranolazine) or P-gp with a narrow therapeutic window, administered orally (e.g., digoxin) within 4 weeks or 5 drug-elimination half-lives of the drug (whichever is longer) prior to initiation of study treatment.

  • Treatment with known strong CYP3A4 inducers (e.g., rifampin, phenytoin, carbamazepine, phenobarbital, and St. John's Wort) or strong CYP3A4 inhibitors (e.g., clarithromycin, grapefruit juice, itraconazole, ketoconazole, posaconazole, telithromycin, and voriconazole) within 4 weeks or 5 half-lives of the drug (whichever is longer) prior to initiation of study treatment.

  • Treatment with known strong UDP-glucuronosyltransferases (UGTs) of UGT1A1, 1A4, 1A9 and 2B4 inhibitors (e.g., atazanavir) within 4 weeks or 5 half-lives of the drug, whichever is longer, prior to the initiation of study treatment

    • Treatment with known sensitive substrates of BSEP within 4 weeks or 5 half-lives of the drug, whichever is longer, prior to the initiation of study treatment
    • Treatment with known sensitive substrates of OCT2 within 4 weeks or 5 half-lives of the drug, whichever is longer, prior to the initiation of study treatment
    • Treatment with known sensitive substrates of MATE1 within 4 weeks or 5 half-lives of the drug, whichever is longer, prior to the initiation of study treatment
