Brief summary
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
Detailed 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.
Interventions
DRUGIpilimumab
YERVOY is thought to work with the body's immune system to increase the activity of T cells and cause the body to attack cancer cells
DRUGNivolumab
Nivolumab binds to and blocks the activation of PD-1, an Ig superfamily transmembrane protein, by its ligands programmed cell death ligand 1 (PD-L1), overexpressed on certain cancer cells, and programmed cell death ligand 2 (PD-L2), which is primarily expressed on APCs

After initiation of ipilimumab, Arm B patients underwent imaging after the first 12 weeks and then every 8 weeks until disease progression. Best overall response during Arm B treatment were summarized with 90% confidence interval.

OS rate was estimated using the product-limit method of Kaplan-Meier;18-month OS rate and 95% confidence interval were reported.
Time frame: Patients were followed from initiation of Nivolumab induction until to death or date last known alive. Kaplan-Meier curve for OS assessed up to 28 months; the 18-month time point estimate for OS was reported.

Secondary
Immune Related Objective Response Rate (irORR) in Arm A and Arm B
The irORR is assessed according to immune-related Response Criteria (irRC). * Immune-Related Complete Response (irCR): Complete disappearance of all tumor lesions (index and non-index together with no new measurable/unmeasurable lesions) for at least 4 weeks from the date of documentation of complete response * Decrease, relative to baseline, of 50% or greater in the sum of the products of the two largest perpendicular diameters (SPD) of all target and all new measurable lesions in two consecutive observations not less than 4 weeks apart.
Time frame: For arm A, radiology imaging will be done every 8 weeks until disease progression. For arm B, radiology imaging will be done at 12 weeks and then every 8 weeks until disease progression
Population: Since the trial was designed in 2015, immune-related response has been infrequently used in VEGF/IO trials for kidney cancer. Most RCC trials have mainly focused on the traditional RECIST-based response as the primary endpoint. Therefore, the study team did not pursue immune-related response assessment and that data was not collected.

Progression-free survival (PFS) for Arm B was defined as time from the start of arm B treatment until progression (by RECIST 1.1 or clinical PD) or death from any cause or censored at date of last disease evaluation for those who are alive and have not progressed. PFS distribution was estimated using the product-limit method of Kaplan-Meier, median and 95% confidence interval was reported.
