- Primary Objective
- To assess the overall safety and tolerability of BMS-936558 plus sunitinib or pazopanib, in order to determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of BMS-936558 plus sunitinib or pazopanib in subjects with mRCC.
- Secondary Objective
- To assess preliminary antitumor activity of BMS-936558 plus sunitinib or pazopanib in subjects with mRCC.
- Exploratory Objectives
- To evaluate pharmacodynamic and predictive biomarkers of BMS-936558 plus sunitinib or pazopanib in subjects with mRCC
- To characterize the pharmacokinetics of BMS-936558 in subjects with mRCC and to explore exposure-response with respect to safety, efficacy and biomarkers
- To assess the immunogenicity of BMS-936558
- To assess the overall survival (OS) in mRCC subjects receiving BMS-936558 in combination with sunitinib or pazopanib
- Signed Written Informed Consent
- Willing and able to provide informed consent
- Target Population
- Male and Females age ≥ 18 years of age
- Subjects with histological confirmation of RCC with a clear-cell component (dose escalation or dose expansion) or non-clear-cell RCC, limited to papillary, chromophobe or unclassified histology (dose escalation only)
- Advanced or metastatic disease
- Measurable disease as defined by RECIST 1.1 criteria (Appendix 4)
- In the dose-escalation cohorts, subjects must have received at least one prior systemic treatment regimen in the advanced/metastatic setting (at least one prior cytokine, anti-angiogenic or mTOR inhibitor)
- In the dose-expansion cohorts, subjects must not have received any prior systemic therapy in the advanced/metastatic setting
- Favorable or intermediate-risk MSKCC prognostic score (0 - 1 of 3 risk factors for pre-treated patients in the dose-escalation part, 0 - 2 of 5 risk factors for treatment-naive patients in the dose-expansion part) (Appendix 1)
- Karnofsky Performance Status (KPS) ≥ 80% (Appendix 2)
- Tumor tissue (archival or recent acquisition) must be available (block or 10 - 15 unstained slides of FFPE tissue) for correlative studies
- In Arm I-1 and I-3, subjects may be treatment naive or may have received prior systemic therapy.
- Age and Reproductive Status (See Section 3.3.3 for the definition of WOCBP)
- Women of childbearing potential (WOCBP) must use method(s) of contraception based on the tables in Appendix 9. For a teratogenic study drug and/or when there is insufficient information to assess teratogenicity (preclinical studies have not been done), a highly effective method(s) of contraception (failure rate of less than 1% per year) is required. The individual methods of contraception should be determined in consultation with the investigator. WOCBP must follow instructions for birth control when the half life of the investigational drug is greater than 24 hours, contraception should be continued for a period of 30 days plus the time required for the investigational drug to undergo five half lives.
- WOCBP must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to the start of investigational product.
- Women must not be breastfeeding
- Men who are sexually active with WOCBP must use any contraceptive method with a failure rate of less than 1% per year. Men that are sexually active with WOCBP must follow instructions for birth control when the half life of the investigational drug is greater than 24 hours, contraception should be continued for a period of 90 days plus the time required for the investigational drug to undergo five half lives.
- Target Disease Exceptions
- Active CNS metastases (including evidence of cerebral edema by CT scan or MRI, progression from prior imaging study, any requirement for steroids to control clinical symptoms relating to CNS metastases, or the presence of clinical symptoms relating to CNS metastases) within 30 days of study enrollment. Subjects with known metastases must have a baseline imaging scan within 30 days of treatment assignment
- Medical History and Concurrent Diseases
- Any active or recent history of a known or suspected autoimmune disease or recent history of a syndrome that required systemic corticosteroids or immunosuppressive medications except for syndromes which would not be expected to recur in the absence of an external trigger. Subjects with vitiligo or type I diabetes mellitus are permitted to enroll
- Known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS)
- Positive test for hepatitis B virus surface antigen (HBV sAg) or hepatitis C virus ribonucleic acid (HCV RNA) indicating acute or chronic infection
