Summary

This clinical trial aims to evaluate whether a ketogenic diet (KD), when combined with immunotherapy, can improve immune function and treatment outcomes in patients with advanced melanoma, cutaneous squamous cell carcinoma (cSCC), or renal cell carcinoma (RCC).

Why Is This Study Important? Immunotherapy is a promising cancer treatment, but not all patients respond well. Research suggests that diet, particularly a high-fat, low-carbohydrate ketogenic diet, may help boost the immune system and make treatments more effective.

What Will This Study Examine?

Researchers want to understand:

Is the ketogenic diet well-tolerated for cancer patients? Does the diet improve immune responses and treatment effectiveness?

How Will the Study Work?

Participants will be placed into one of two groups:

Ketogenic Diet (KD) Group: A structured high-fat, low-carb diet (intermittent schedule: 2 weeks on, 1 week off).

Standard Diet (SD) Group: A typical diet with no major changes. Throughout the study, a dietitian will closely support and guide you. Both groups will continue their standard immunotherapy treatment.

What Will Participants Do? Write their food intake three times a week to help assess dietary adherence Follow their assigned diet for 10 weeks Have weekly check-ins with a dietitian (in-person at the hospital or via phone) Have weekly blood glucose and ketone level checks using a home device. Provide monthly blood samples to measure immune response during routine immunotherapy infusions Provide stool samples for gut microbiome analysis at the start and end of the study Measure Monthly Weight, body composition, and resting calorie burn Complete quality-of-life questionnaires

What Are the Potential Benefits? Improved response to immunotherapy Better understanding of how diet influences cancer treatment Potential for a new supportive strategy for cancer care

This study may help uncover ways to enhance cancer treatment through personalized nutrition.

DIETARY_SUPPLEMENT

Ketogenic diet

Ketogenic Diet as an Adjunct to Immunotherapy: Unlike many trials focused on chemotherapy or targeted therapies, this study specifically investigates the synergistic effects of the ketogenic diet with immune checkpoint inhibitors (ICIs), a promising approach for enhancing immunotherapy efficacy. The diet's high-fat, low-carbohydrate regimen is designed to shift metabolism towards ketone bodies and fatty acid utilization, potentially modulating immune responses and tumor immunogenicity in a way that standard diets do not.
