Accepting Healthy Volunteers?
- For Phase 1, subjects with histologically or cytologically confirmed advanced or metastatic solid tumors that have failed prior standard therapy (disease progression; subject intolerance is also allowable).
- For Phase 2, subjects with the following tumor types who meet protocol-defined criteria: advanced or metastatic NSCLC, melanoma, urothelial carcinoma, SCCHN, SCLC, and CRC.
- Presence of at least 1 measurable lesion by computed tomography or magnetic resonance imaging per RECIST v1.1.
- Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1.
- Resolution of all toxicities and any toxic effect(s) of the most recent prior therapy to Grade 1 or less (except alopecia). Subjects with ≤ Grade 2 neuropathy are an exception and may enroll.
- Adequate renal, hepatic, and hematologic functions per protocol-defined laboratory parameters within ≤ 7 days before treatment initiation.

- Prior chemotherapy or targeted small molecule therapy within 2 weeks before administration of study treatment.
- Prior therapy with an IDO1 or arginase 1 inhibitor.
- Active autoimmune disease that has required systemic treatment in past 2 years. Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
