Sitravatinib and Nivolumab in Treating Patients With Advanced or Metastatic Kidney Cancer

PRIMARY OBJECTIVES:

I. To determine the toxicities (defined as a grade 3 or 4 National Cancer Institute \[NCI\] non-hematologic or hematologic adverse event, within 12 weeks from treatment initiation), and efficacy (defined as achieving complete remission, partial remission, or stable disease within 6 weeks) of sitravatinib (MGCD516) when administered orally (PO) daily in combination with standard dose nivolumab 240 mg/kg every 2 weeks.

SECONDARY OBJECTIVES:

I. To estimate the overall survival (OS), progression-free survival (PFS) times, objective response rates (ORR), and quality of life (QOL) of patients with advanced clear cell renal cell cancer (RCC) treated with the combination of MGCD516 and nivolumab.

II. Evaluate potential biomarkers for patient stratification and treatment response, including genetic analysis, serum cytokines and chemokines, as well as tumor antigen-specific immune responses, such as antibody and T cell responses, as surrogates for anti-tumor activity.

OUTLINE:

Patients receive sitravatinib PO once daily (QD) on days 1-14 and receive nivolumab intravenously (IV) over 60 minutes on day 1 starting cycle 2. Cycles repeat every 14 days for cycles 1-6 and then every 28 days for subsequent cycles in the absence of disease progression or unacceptable toxicity. Patients who receive at least 6 infusions of nivolumab with no dose limiting toxicities (DLTs) related to nivolumab, may then receive nivolumab every 4 weeks.

After completion of study treatment, patients are followed up at 30 days and then every 3 months.

Primary outcomes

• Number of Participants Who Experienced Dose-Limiting Toxicities (DLTs) [from enrollment up to 12 weeks for each dosing group]: To determine the toxicities (defined as a grade 3 or 4 National Cancer Institute \[NCI\] non-hematologic or hematologic adverse event, within 12 weeks from treatment initiation),and efficacy (defined as achieving complete remission, partial remission, or stable disease within 6 weeks) of dosing.

Secondary outcomes
