Inclusion Criteria
  • Participant is Japanese
  • Histologically or cytologically confirmed diagnosis of any locally advanced or metastatic solid tumors not amenable to local or other curative therapy.
  • Participants with nonevaluable lesions are allowed.
  • Life expectancy > 3 months.
  • Eastern Cooperative Oncology Group performance status 0 to 1.
  • Female participants agree to use medically acceptable contraceptive measures, should not be breastfeeding, and must have a negative pregnancy test before the start of study drug administration.
  • Female participants of childbearing potential must understand and accept that pregnancy must be avoided during participation in the study.
  • Male participants should avoid unprotected sex with women of childbearing potential and refrain from donating sperm during participation the study.
Exclusion Criteria
  • Receipt of anticancer therapy or participation in another interventional clinical study within 14 days before the first administration of study drug with the following exceptions: Immunotherapy or biological therapy (eg, monoclonal antibodies) within 21 days the first administration of study drug; 6 weeks for mitomycin-C or nitrosoureas; 7 days for tyrosine kinase inhibitors.
  • Radiotherapy within 14 days of first dose of study treatment with the following exceptions: 28 days for pelvic radiotherapy; 6 months for thoracic region radiotherapy that is > 30 Gy.

Note: Endocrinopathy, if well-managed, is not exclusionary and should be discussed with sponsor medical monitor.
  • Receipt of prior systemic treatment with an arginase inhibitor
  • Immune-related toxicity during prior checkpoint inhibitor therapy for which permanent discontinuation of therapy is recommended (per product label or consensus guidelines), OR any immune-related toxicity requiring intensive or prolonged immunosuppression to manage (with the exception of endocrinopathy that is well controlled on replacement hormones).
  • Active autoimmune disease requiring systemic immunosuppression in excess of physiologic maintenance doses of corticosteroids (> 10 mg of prednisone or equivalent).
  • Known active central nervous system metastases and/or carcinomatous meningitis.
  • Known active hepatitis A virus, hepatitis B virus, or hepatitis C virus infection.
  • Known HIV infection.
  • Active infections requiring systemic therapy.
  • Known hypersensitivity to another monoclonal antibody that cannot be controlled with standard measures and/or known hypersensitivity ≥ Grade 3, or severe reaction, to study treatments or any of their excipients or additives.
  • Participants with impaired cardiac function or clinically significant cardiac disease.
  • Evidence of interstitial lung disease or active, noninfectious pneumonitis or a history of interstitial lung disease.
  • Participant is pregnant or breastfeeding.
