situ carcinoma of any site, adequately treated (without recurrence post-resection or
post- radiotherapy) carcinoma of the cervix or basal or squamous cell carcinomas of
the skin, or active non-threatening second malignancy that would not, in the
investigator's opinion, potentially interfere with the patient's ability to
participate and/or complete this trial. Examples include but not limited to:
urothelial cancer grade Ta or T1, adenocarcinoma of the prostate treated by active
surveillance
- Patients currently receiving anticancer therapies or who have received anticancer
therapies within 2 weeks (14 days) from enrollment into this study (including
chemotherapy and targeted therapy) are excluded. Also, patients who have completed
palliative radiation therapy more than 14 days prior to the first dose of sitravatinib
are eligible
- Patients who had a major surgery or significant traumatic injury (injury requiring >
28 days to heal) within 28 days of start of study drug, patients who have not
recovered from the side effects of any major surgery (defined as requiring general
anesthesia), or patients that are expected to require major surgery during the course
of the study
- Patients with a prior history of grade 3 or worse immune-related adverse events
attributed to CPIs (PD-1, PD-L1, or CTLA-4), except endocrine adverse events with
appropriate hormone replacement or asymptomatic amylase/lipase elevations
- Active or prior documented autoimmune disease, as follows:
- Inflammatory bowel disease (eg, Crohn's disease, ulcerative colitis)
- Interstitial lung disease (ILD), drug-induced ILD, radiation pneumonitis that
required steroid treatment, or any evidence of clinically active ILD.

first dose of study treatment, with the exception of topical, ocular, intranasal,
and inhaled corticosteroids, or systemic corticosteroids at an equivalent dose =<
10 mg of prednisone daily
- Any underlying medical condition, which in the opinion of the Investigator, will make
the administration of study drug hazardous or obscure the interpretation of adverse
events, such as a condition associated with frequent diarrhea, uncontrolled nausea,
vomiting, malabsorption syndrome or small bowel resection that may significantly alter
the absorption of sitravatinib
- Patients receiving any concomitant systemic therapy for renal cell cancer are excluded
- Patients must not be scheduled to receive another experimental drug while on this
study

conditions that could affect their participation in the study such as:

- Liver disease, such as cirrhosis or chronic active hepatitis; Positive test for
hepatitis B virus (HBV) using HBV surface antigen (HBV sAg) test or positive test

indicating acute or chronic infection
- Patients must not have history of other diseases, metabolic dysfunction, physical
examination finding, or clinical laboratory finding giving reasonable suspicion of a
disease or condition that contraindicates the use of sitravatinib or nivolumab or that
might affect the interpretation of the results of the study or render the subject at
high risk from treatment complications
- Patients should not receive immunization with attenuated live vaccines within one week
(7 days) of study entry or during study period
- Uncontrolled brain or leptomeningeal metastases, including patients who continue to
require glucocorticoids for brain or leptomeningeal metastases
- Female patients who are pregnant or breast feeding, or adults of reproductive
potential who are not using effective birth control methods. If a patient can become
pregnant or father a child, appropriate birth control methods, including a
double-barrier method (2 methods at the same time), are required while on study and
for 23 weeks (females) or 31 weeks (males) after you stop receiving the study drugs.
If barrier contraceptives are being used, these must be continued throughout the trial
by both sexes. Hormonal contraceptives are not acceptable as a sole method of
