Brief Summary

This phase I trial studies how well a ketogenic dietary intervention works to improve response to immunotherapy in patients with melanoma and kidney cancer that has spread from where it first started (primary site) to other places in the body (metastatic). A ketogenic diet (KD) means eating fewer carbohydrates and more fats. The purpose is to use ketones (normal breakdown from fat) instead of glucose (sugar) as an energy source. Researchers want to see whether a ketogenic diet can improve tumor response in patients receiving immune checkpoint inhibitors (ICI). ICI are newer treatment options that help the immune system better fight some cancers. Following a KD may improve tumor response in patients with metastatic melanoma and metastatic kidney cancer treated with ICI.

Outcome Measures

Primary Outcomes (2)

  • Incidence of adverse events

    Will be assessed by immune-related adverse events (irAEs), serious adverse events (SAEs), Treatment Emergent Adverse Events (TEAEs), clinical laboratory, vital signs, physical examinations. Will be monitored during study visits and telephone calls using the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0, which also includes irAEs. Grade 3, 4 and 5 toxicities will be reported as adverse events.

    Up to 1 year

  • Adherence (feasibility measure)

    Adherence will be defined as \> 80% of days in ketosis and compliant as collecting all gut microbiome specimens. Diet adherence and progress will be assessed daily using at-home whole capillary blood glucose and continuous ketone monitoring devices

    Up to 1 year

Study Arms (2)

Arm I (Ketogenic diet)

EXPERIMENTAL

Patients undergo a ketogenic dietary intervention with personalized coaching from a dietician about the KD, which includes extensive educational and ongoing support on the KD and continuous ketone monitoring by talking to a dietician directly, with the ability to text a dietician at any time and expect a response within 12 hours over 24weeks. Patients also undergo daily blood glucose and ketone monitoring, undergo CT, undergo blood sample collection and may undergo stool sample collection on the study.
