RECRUITINGPhase 2INTERVENTIONAL
Prebiotic Food-enriched Diet (PreFED) to Enhance the Microbiome and Response to First-line Immunotherapy in Unresectable Melanoma
About This Trial
To learn about the possible effects of a prebiotic food-enriched diet (PreFED) targeting the gut microbiome in participants with melanoma who are starting immune checkpoint blockade (ICB) therapy.
Who May Be Eligible (Plain English)
Who May Qualify:
- Age ≥18 years old
- English-speaking
- Body mass index (BMI) 18.5-45 kg/m2
- Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
- diagnosed by tissue sample (biopsy-confirmed) stage III/IV, unresectable cutaneous, uveal, acral or mucosal melanoma. Asymptomatic brain metastases are allowed.
- Planned initiation of 1st line standard-of-care approved immune checkpoint blockade (anti-PD1 +/- anti-CTLA4 or anti-LAG3 inhibitors or talimogene laherparepvec T-VEC) in the metastatic setting. Prior targeted therapy or ICB in the adjuvant setting is allowed.
- Returning to MD Anderson for restaging and follow-up (ICB treatment may occur locally)
- tumors that can be measured on scans 1.1 or RANO criteria. Up to 10 patients without measurable can be enrolled.
- WOCP must have negative UPT within 1 week of beginning dietary intervention.
- Self-reported willingness to eat the provided foods (with some tailoring to their food preferences)
- Self-reported willingness to comply with scheduled visits, undergo venipuncture, provide stool samples.
Who Should NOT Join This Trial:
- Previous ICB treatment in the metastatic setting
- History of inflammatory bowel disease, total colectomy, or bariatric surgery.
- Currently taking steroids \> Prednisone 10 mg/day or equivalent
- Medical contraindications to the Intervention Diet as determined by the treating physician.
- Self-reported major dietary restrictions, including but not limited to relevant food allergies, celiac disease, or diets such as vegan, ketogenic, extended fasting.
- Insulin-dependent diabetes or condition requiring bile acid sequestrants
- Unable or unwilling to undergo study procedures.
- IV antibiotic use in the past month or oral antibiotic use in past 2 weeks.
- Regularly taking supplements containing prebiotics, fiber and/or probiotics, and unable/unwilling to discontinue for the purpose of the study.
