Normal organ and marrow function as defined below:
- Absolute neutrophil count > 1000/mcL
- Hemoglobin > 11 g/dL
- Platelets > 100,000/mcL
- Total bilirubin < 1.5 X normal institutional limits
- Aspartate aminotransferase (AST) / alanine aminotransferase (ALT) < 2.5 X institutional ULN or ≤ 5.0 × ULN for patients with documented liver metastases.
- Creatinine within normal institutional limits
- Creatinine clearance ≥ 30 mL/min

Women of child bearing age and actively menstruating must have a negative pregnancy test prior to starting study treatment.
If sexually active in a way that could lead to pregnancy, participant must agree to use a highly effective method of birth control starting at the time of informed consent and continuing throughout the study and for at least 3 months after the final dose of sitravatinib.

Exclusion criteria

Uncontrolled hypertension defined as systolic blood pressure > 150 and/or diastolic blood pressure > 100, on two or more occasions within 30 days prior to enrollment.
Imaging suggestive of Lymphangitic carcinomatosis in the lung, or use of home oxygen
Untreated brain metastases.
Women who are pregnant or nursing
Concurrent metastatic disease of another tumor type
Impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of sitravatinib

Concurrent medical condition that, in the sole judgment of the principal investigator, would make the patient inappropriate for trial participation.
