Brief Summary:
This is a phase I/II open-label study designed to evaluate the combination of pembrolizumab and cabozantinib in subjects with locally advanced, recurrent, or metastatic renal cell carcinoma. Sequential dose escalation of cabozantinib with standard dose pembrolizumab will occur in the phase I dose escalation part of the study to determine the recommended phase 2 dose (RP2D). Subsequently, subjects will receive cabozantinib at the RP2D in combination with pembrolizumab in the phase II dose expansion part of the study.

Condition or disease Intervention/treatment Phase
Metastatic Renal Cell Carcinoma Drug: Cabozantinib Drug: Pembrolizumab Phase 1 Phase 2

Detailed Description:

Primary Objectives

  • To determine the efficacy based on objective response rate [ORR = complete response (CR) + partial response (PR)] of pembrolizumab and cabozantinib when administered in combination in subjects with locally advanced or metastatic renal cell carcinoma.

Primary Outcome Measures :
  1. Efficacy of Pembrolizumab and Cabozantinib Based on Objective Response Rate [ Time Frame: Beginning of study to end of study, up to 5 years ]
    Measured through the complete response (CR) + partial response (PR)] of pembrolizumab and cabozantinib when administered in combination in subjects with locally advanced or metastatic renal cell carcinoma.


Secondary Outcome Measures :
  1. Maximally Tolerated Dose (MTD) [ Time Frame: Throughout Cycle 1, up to 21 days ]
    MTD is defined as the highest dose level with no more than 1 DLT reported in 6 DLT-evaluable subjects.

  2. Recommended Phase 2 Dose [ Time Frame: Throughout Cycle 1, up to 21 days ]
    The Recommended Phase 2 Dose (RP2D) of cabozantinib will be selected based on the clinical data and will not exceed the MTD. If < 2/6 subjects experience a DLT at 60 mg daily during dose escalation, then 60 mg daily will be considered the RP2D. If ≥ 2/6 subjects experience DLTs at 60 mg daily, and ≤ 1/6 subjects experience a DLT at 40 mg daily, then 40 mg daily will be considered the RP2D. The dose of pembrolizumab will be constant at 200 mg IV every 3 weeks.

  3. Dose Limiting Toxicities [ Time Frame: Throughout Cycle 1, up to 21 days ]
    Assessed through Common Terminology Criteria for Adverse Events (CTCAE) v 4.0

  4. Progression-Free Survival [ Time Frame: Beginning of study to end of study, or death, whichever comes first, up to 5 years ]
    Measured as the time it takes for an occurrence of documented disease progression

  5. Progression of Overall Disease [ Time Frame: Beginning of study to end of study, or death, whichever comes first, up to 5 years ]
    Measured according to RECIST 1.1 and irRECIST

  6. Progression of Bone Metastasis or Skeletal Related Event (SRE) [ Time Frame: Beginning of study to end of study, or death, whichever comes first, up to 5 years ]
    Measured according to RECIST 1.1 and irRECIST

  7. Clinical Benefit Rate [ Time Frame: Beginning of study to end of study, or death, whichever comes first, up to 5 years ]
    Measured as complete response (CR) + partial response (PR) + stable disease (SD)

  8. Duration of Disease Stability [ Time Frame: Beginning of study to end of study, or death, whichever comes first, up to 5 years ]
    Measured according to RECIST 1.1 and irRECIST

  9. Duration on Treatment in Subjects Beyond Treatment Progression [ Time Frame: Beginning of study to end of study, or death, whichever comes first, up to 5 years ]
    Measured according to RECIST 1.1 and irRECIST

  8. Have a performance status of 0 or 1 on the ECOG Performance Scale.
  9. Demonstrate adequate organ function as defined by desired lab values.
  10. Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
  11. Female subjects of childbearing potential (Section 5.7.2) must be willing to use an adequate method of contraception as outlined in Section 5.7.2 - Contraception, for the course of the study through 120 days after the last dose of study medication. Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.
  12. Male subjects of childbearing potential (Section 5.7.1) must agree to use an adequate method of contraception as outlined in Section 5.7.1- Contraception, starting with the first dose of study therapy through 120 days after the last dose of study therapy.
