Study Details

Study Description

Brief Summary

This study is being done with patients with advanced kidney cancer (also called renal cell carcinoma or RCC). This is a research study involving the use of the drug Nivolumab (also known as Opdivo®). Nivolumab is an anti-PD-1 antibody. It works by attaching to and blocking a molecule called PD-1. PD-1 is a protein that is present on different types of cells in the immune system and controls parts of the immune system by shutting it down. Antibodies that block PD-1 can potentially prevent PD-1 from shutting down the immune system, thus allowing it to recognize and help destroy cancer cells. In many countries (including the United States, European Union and Japan) Nivolumab is approved to treat certain cancer types. The purpose of the study is to test the safety and effectiveness of nivolumab in patients with advanced RCC when given intermittently.

Nivolumab is approved by the U.S. Food and Drug Administration (FDA) for the treatment of advanced kidney cancer, non small cell lung cancer, classical Hodgkin Lymphoma and Metastatic Melanoma. Nivolumab is FDA-approved for advanced RCC because has been shown to shrink RCC tumors that have spread outside the kidney.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Cohort I: Intermittent Nivolumab Nivolumab monotherapy. Participants who have initial 10% or greater tumor burden reduction will discontinue nivolumab until they experience a pre-specified disease progression at which time nivolumab will be restarted	Drug: Nivolumab Nivolumab monotherapy will be administered dosed at 480mg IV over 30 minutes for all patients every 4 weeks, regardless of weight (when given in combination with ipilimumab, the dose of nivolumab is 3mg/kg every 3 weeks). Tumor assessed after 12 weeks If tumor decreases by 10% or more, then hold drug for 12 week and test tumor again. Continue treatment if tumor is not decreased by 10% or more. Other Names: Opdivo®
Experimental: Cohort II: combination ipilimumab/nivolumab Combination of ipilimumab/nivolumab for previously untreated intermediate and poor risk mRCC Includes participants treated front-line ipilimumab/nivolumab. Participants with treatment-naïve mRCC who receive up to four doses of induction ipilimumab/nivolumab and 24 weeks (+/- 8 weeks; minimum 3 infusions) of maintenance nivolumab and achieve stable disease (SD), complete response (CR), or partial response (PR) will be eligible for inclusion. Participants who achieve SD will continue with nivolumab maintenance per standard of care while those who achieve a PR or CR will enter an observation period off therapy. Upon disease progression, participants will be re-challenged with combination ipilimumab/nivolumab.

Outcome Measures

Primary Outcome Measures

the proportion of patients who receive intermittent therapy [Expected duration 5.5 months]
For cohort I: Assess feasibility of an intermittent dosing schedule, where feasibility is defined in terms of the proportion of patients eligible for intermittent therapy who actually receive it. An underlying acceptance rate of >80% is arbitrarily considered necessary in order to accept the intermittent schedule as feasible whereas an acceptance rate <50% is considered evidence that the intermittent schedule is not feasible
Rate of participants who maintain CR/PR off therapy for at least 9 months [Up to 9 months after treatment]
For cohort II: Rate of participants who maintain CR/PR off therapy for at least 9 months

Secondary Outcome Measures

Change in tumor burden [Expected duration 5.5 months]
Objective Response [Expected duration 5.5 months]
Number of patients with tumor response per the RECIST 1.1 Criteria: Complete response (CR) is defined as the disappearance of all target lesions. Any pathological lymph nodes (whether target or non target) must have reduction in short axis to <10 mm. Partial response (PR) is defined as a greater than or equal to 30% decrease in the sum of the longest dimensions of the target lesions Progressive disease (PD) is defined as a greater than or equal to 20% increase in the sum of the longest dimensions of the target lesions, or the appearance of one or more new lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. Stable disease (SD) is defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD
Length of Progression Free Survival [Expected duration 5.5 months]
Time from enrollment in the study to progression, when progression is defined as a greater than or equal to 20% increase in the sum of the longest dimensions of the target lesions taking as a reference the smallest sum of the longest dimensions recorded since the treatment started, or the appearance of one or more new lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.
Percent of patients who experience grade 3 AE or higher with re-induction ipi/nivo [up to 100 days after end of treatment]
Estimate toxicity rate in participants undergoing reinduction with ipilimumab/nivolumab as measured by percent of patients who experience grade 3 AE or higher

Must have received at least one but not more than two prior anti-angiogenic therapy regimens (including, but not limited to, sunitinib, sorafenib, pazopanib, axitinib, tivozanib, and bevacizumab) in the advanced or metastatic RCC setting. Prior cytokine therapy (for example, Interleukin (IL)-2, interferon (IFN)-α), vaccine therapy, or treatment with cytotoxics is also allowed.
Patients treated with neoadjuvant and/or adjuvant therapy prior to development of metastatic disease may also be included provided that at least 12 months have elapsed since last dose. These regimens do not count toward total number of prior therapies permitted for trial inclusion.
