Inactive

ClinicalTrials ID:NCT06250335

Patient View

This trial evaluates the effects of a prebiotic diet on ICB-refractory melanoma patients receiving ipilimumab/nivolumab. It aims to assess response rates, survival, safety, and gut microbiome changes. Eligible participants are adults with specific health criteria, excluding those with certain medical conditions or dietary restrictions. Interventions include a prebiotic diet and IV-administered drugs.

Patient Parameters

Program Overview

To learn about the possible effects of a prebiotic food-enriched diet (PreFED) targeting the gut microbiome in participants with ICI-refractory melanoma who are receiving the combination of ipilimumab and nivolumab as part of their standard care.

Description

Primary Objectives Determining the overall response rate (ORR) to PreFED intervention + Ipi/Nivo in ICB-refractory metastatic melanoma participants.

Secondary Objectives

  1. Determine progression-free survival (PFS) and overall survival (OS) to PreFED + Ipi/Nivo in ICB refractory melanoma
  2. Compliance and adherence to interventions
  3. Determine the safety (AEs) and tolerability (GSRS-IBS) of the dietary intervention
  4. Assess the rate of immune related adverse events in participants on immunotherapy receiving dietary interventions
  5. Assess the effects of dietary intervention on systemic and tumor immunity
  6. Assess the effect of dietary intervention on gut microbiome composition and networks
  7. Assess the effects of dietary intervention on gut metabolic output and systemic metabolism
  8. Assess the effects of dietary interventions on quality of life and other participant reported outcomes (PROs)
