Inulin Gel in Combination With Ipilimumab and Nivolumab for the Treatment of Metastatic or Locally Advanced Kidney Cell Cancer, ICON Trial

This phase I/II trial tests the safety and effectiveness of inulin gel in combination with ipilimumab and nivolumab in treating patients with kidney cell cancer (renal cell carcinoma \[RCC\]) that has spread from where it first started (primary site) to other places in the body (metastatic) or has spread to nearby tissue or lymph nodes (locally advanced). Inulin is a common food additive fermentable prebiotic fiber beneficial for a healthy gut microbiome. The microbiome is the collection of all microbes, such as bacteria, fungi, viruses, and their genes, that naturally live on and inside the body. Inulin may also be used for cancer prevention and heart health, but there is less evidence to support those uses. The gut microbiome profile may improve the effectiveness of drugs called immune checkpoint inhibitors, such as ipilimumab and nivolumab. Immunotherapy with monoclonal antibodies, such as ipilimumab and nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving inulin gel in combination with ipilimumab and nivolumab may be safe and effective in treating in patients with metastatic or locally advanced RCC.
