About
This phase I trial tests the safety, side effects, and best dose of camu camu when used in combination with nivolumab and ipilimumab in treating patients with kidney cancer that has spread to other places in the body. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Camu camu is a prebiotic that may have a beneficial effect on the immune system. Giving camu camu in combination with nivolumab and ipilimumab may kill more tumor cells than nivolumab and ipilimumab alone in patients with metastatic kidney cancer.
Full description
PRIMARY OBJECTIVE:
I. To determine the effect of camu camu in combination with nivolumab/ipilimumab on Ruminococcus abundance in stool samples of patients with metastatic renal cell carcinoma (mRCC).
SECONDARY OBJECTIVES:
I. To evaluate the effect of camu camu on the clinical efficacy of the nivolumab/ipilimumab combination.
II. To determine the effect of camu camu on systemic immunodulation of the nivolumab/ipilimumab combination in patients with mRCC.
III. To describe the toxicity and safety profile of the use of camu camu in combination with nivolumab/ipilimumab.
IV. To determine the effect of camu camu on gut microbiome diversity and function.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM 1: Patients receive nivolumab intravenously (IV) over 30 minutes on day 1 and ipilimumab IV over 30 minutes on day 1 of each cycle. Cycles repeat every 3 weeks for cycles 1-4. Beginning cycle 5, patients receive nivolumab over 30 minutes on day 1 of each cycle. Cycles repeat every 4 weeks in the absence of disease progression or unacceptable toxicity. Patients also undergo blood and stool sample collection and undergo computed tomography (CT) and/or bone scan and/or magnetic resonance imaging (MRI) on trial.
ARM 2: Patients receive nivolumab IV over 30 minutes on day, ipilimumab IV over 30 minutes on day 1, and camu camu orally (PO) once a day (QD) continuously with each cycle. Cycles repeat every 3 weeks for cycles 1-4. Beginning cycle 5, patients receive nivolumab over 30 minutes on day 1, and camu camu PO QD of each cycle. Cycles repeat every 4 weeks in the absence of disease progression or unacceptable toxicity. Patients also undergo blood and stool sample collection and undergo CT and/or bone scan and/or MRI on trial.
After completion of study treatment, patients are followed up every 12 weeks until time of death or formal withdrawal from the study, whichever comes first.

Exclusion criteria
- Presence of untreated brain metastases. Patients with treated brain metastases must be stable for 4 weeks after completion of treatment and have documented stability on pre-study imaging. Patients must have no clinical symptoms from brain metastases and have no requirement for systemic corticosteroids amounting to > 10 mg/day of prednisone or its equivalent for at least 2 weeks prior to first dose of study drug. Patients with known leptomeningeal metastases are excluded, even if treated
- Favorable risk disease by IMDC classification
- Prior treatment with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti-CTLA-4 antibody, or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways
- Any active or recent history of a known or suspected autoimmune disease or recent history of a syndrome that required systemic corticosteroids (> 10 mg daily prednisone equivalent) 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 or residual hypothyroidism due to autoimmune thyroiditis only requiring hormone replacement are permitted to enroll
- Active interstitial lung disease (ILD)/pneumonitis or history of ILD/pneumonitis requiring treatment with systemic steroids

- Any condition requiring systemic treatment with corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days prior to first dose of study drug. Inhaled steroids and adrenal replacement steroid doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease
- Uncontrolled adrenal insufficiency
- Known medical condition (e.g., a condition associated with diarrhea or acute diverticulitis) that, in the investigator's opinion, would increase the risk associated with study participation or study drug administration or interfere with the interpretation of safety results
- Not recovered to =< Grade 1 toxicities related to any prior therapy before administration of study drug
- Women who are pregnant or breastfeeding
- History of myocarditis or congestive heart failure (as defined by New York Heart Association Functional Classification III or IV), as well as unstable angina, serious uncontrolled cardiac arrhythmia, uncontrolled infection, or myocardial infarction 6 months prior to study entry
