Detailed Description
This is a single center, open-label, non-randomized, pre-operative window of opportunity study for patients with resectable squamous cell carcinoma of the oral cavity who are considered suitable for curative-intent surgical resection, with pre-operative Sitravatinib and Nivolumab. A total of 12 patients who are evaluable for correlative studies, are planned for enrollment.
This study will involve treatment with Sitravatinib and Nivolumab, tests and procedures done for safety and the collection of blood samples for biomarker research. Tissue samples (fresh biopsy or archival tissue) will also be collected for biomarker research and evaluation.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Sitravatinib and Nivolumab Patients will start therapy with sitravatinib within 10 days of study enrollment. Sitravatinib will be given at 120mg once daily on a continuous basis until 48 hours before planned surgery, or for a maximum period of 28 days. Nivolumab will be given as a single infusion at a dose of 240mg, over a period of 30 minutes on Day 15 of the study. |
Drug: Sitravatinib
Sitravatinib (MGCD516) is an orally-available, potent small molecule inhibitor of a closely related spectrum of tyrosine kinases, which has shown antitumor activity in a variety of in vitro and in vivo model systems.
Other Names:
Biological: Nivolumab
Nivolumab (OPDIVO®) is a human IgG4 kappa immunoglobulin that binds to the PD-1 receptor and blocks its interaction with PD-L1 and PD-L2, releasing PD-1 pathway-mediated inhibition of the immune response, including the anti-tumor immune response.

• Cardiac function: i. A normal left ventricular ejection fraction (LVEF) of ≥50% by a MUGA scan performed within 4 weeks of the study commencement.
- Evidence of post-menopausal status, or negative urinary or serum pregnancy test for female pre-menopausal patients. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply:
-
Women <50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatments and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
-
Women ≥50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses >1 year ago, had chemotherapy-induced menopause with last menses >1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
