About

This research study is studying two drugs at different time points as a possible treatment for advanced renal cell cancer

The drugs involved in this study are:

Nivolumab Ipilimumab

Full description

This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of investigational drugs to learn whether the drugs work in treating a specific disease. "Investigational" means that the intervention is being studied.

Nivolumab and ipilimumab are antibodies (a type of human protein) that work to stimulate your body's immune system to fight tumor cells. The FDA (the U.S. Food and Drug Administration) has approved nivolumab as a treatment option for this disease; however, the FDA has not approved the way nivolumab and ipilimumab are being administered in this study. Ipilimumab is FDA approved for the treatment of melanoma (skin cancer) and has been previously studied in renal cell cancer.

This study is being done to evaluate nivolumab treatment strategies based on each patients individual response to treatment. In participants who have a response to treatment, nivolumab will be stopped and participants will be closely monitored. In participants who do not have a response to treatment,the investigators will investigate whether the addition of ipilimumab improves a participant response to treatment. Participant blood and tissue samples will be collected to learn about how certain biomarkers and genes relate to participant outcomes.

Enrollment: 85 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion and exclusion criteria

• Age ≥ 18 years at the time of consent.
• ECOG Performance Status of ≤ 2 within 28 days prior to registration.
• Unresectable advanced or metastatic RCC to include both clear cell and non-clear histologies.

oPatients who have suspected metastatic RCC, which has not yet been pathologically proven, may be enrolled if they plan to undergo a cytoreductive nephrectomy, metastectomy, or biopsy. Fresh tissue from one of these procedures can be used for the clinical trial requirements (eligibility #4) as well as serve as pathologic confirmation of RCC. The pathologic confirmation must be documented prior to C1D1.

• Availability at the study site of formalin-fixed, paraffin-embedded (FFPE) archival tumor specimens, when available, and willingness of the subject to undergo mandatory fresh tumor biopsy prior to treatment initiation unless determined medically unsafe or not feasible. If a target lesion is biopsied at screening, this lesion must be followed as non-target lesion after the biopsy unless it is the patient's only target lesion. If there is only one target lesion, it should be followed as a target lesion regardless.

  • The archival specimen must contain adequate viable tumor tissue.
  • The specimen may consist of a tissue block (preferred and should contain the highest grade of tumor) or at least 30 unstained serial sections. Fine-needle aspiration, brushings, cell pellet from pleural effusion, bone marrow aspirate/biopsy are not acceptable.
