Renal cell carcinoma (RCC) is the sixth most common cancer in men and the eighth in women in the USA. In Italy RCC incidence was 11500 new cases in 2017, while mortality was 3371 cases in 2015. Increasing evidence suggests that response to immune checkpoint inhibitors (ICIs), a novel treatment for advanced RCC (aRCC) and other epithelial tumors, can be influenced by the patient gut microbiota. Fecal microbiota transplantation (FMT) is a novel therapeutic option based on the restoration of healthy gut microbiota, and is the most effective therapy for recurrent C. difficile infection, and preliminary nonrandomized findings show that FMT is able to improve efficacy of ICIs in patients with advanced melanoma. The aim of this study is to evaluate, through a randomized controlled trial, the efficacy of targeted FMT (from donors who are responding to ICI. in improving response rates to ICIs in subjects with aRCC.

Fecal microbiota transplantation (FMT) is a novel therapeutic option based on the restoration of healthy gut microbiota, and is the most effective therapy for recurrent C. difficile infection, and preliminary nonrandomized findings show that FMT is able to improve efficacy of ICIs in patients with advanced melanoma. The aim of the study is to evaluate, through a randomized controlled trial, the efficacy of targeted FMT (from donors who are responding to ICI) in improving response rates to ICIs in subjects with aRCC. So, the investigators will investigate, through a randomized controlled trial, if donor FMT will be more effective than placebo FMT in improving response to ICIs in patients with renal cell carcinoma. Patients will undergo the first infusion by colonoscopy. Then, patients will receive frozen fecal capsules (8 capsules t.i.d.) at 3 and 6 months after the first FMT.

Fifty patients will be enrolled. Sample size calculation was based on the hypothesis of the superiority of FMT+SOC over SOC alone. The 1-year PFS rate for SOC has been reported to be nearly 60%. The alternative hypothesis is that FMT can improve the 1-year PFS rate from 60% to 80% wen associated to SOC. A total of 50 patients will enter this two-treatment parallel-design study. The probability is 80 percent that the study will detect a treatment difference at a one-sided 5.0 percent significance level, if the true hazard ratio is 0.436. This is based on the assumption that the accrual period will be 18 months and the follow up period will be 12 months and the median survival is 15.1 months. The total number of events will be 35. Microbiome analysis will be performed with shotgun sequencing techniques.

To mask treatments to physicisans and recipients, both FMT bottles and syringes will be covered with dark-coloured paper before the infusion, and the patients will be unable to see the endoscopic display during the procedure. Moreover, the physicians who will evsaluate patients at follow-up will not aware of the treatment being administered.

Individual participant data will be available to other researchers

The investigators will evaluate the number of participants who will be free from tumor progression, as assessed by RECIST criteria v. 1.1., after treatments, at 12 month-follow-up

The investigators will evaluate the number of participants who will obtain a partial or a complete tumor response to immunotherapy, as assessed by RECIST criteria v. 1.1, after treatments, at 12 month-follow-up

The investigators will evaluate the number of participants who will die for any reason throughout the study period (12 months)

The number of participants with treatment-related adverse events (assessed by CTCAE v4.0) will be recorded throughout the study period (12 months)

Throughout the study period (12 months) the investigators will evaluate the number of participants with significant increase in alpha-diversity (assessed by Shannon index) and beta-diversity (assessed by Bray-Curtis dissimilarity) of their gut microbiota after treatments, compared with baseline
