About this study

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.

Read the detailed 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)
Being tested
Prebiotic Food-Enriched Diet, Ipilimumab, Nivolumab

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Overall response rate

    ORR is defined as the proportion of participants whose best overall response BOR is either CR or PR. Best overall response is defined as the best response designation recorded between the date of first dose and the date of first objectively documented progression or the date of subsequent therapy, whichever occurs first per RECIST v1.1.

    Measured: Up to 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Prebiotic Food-Enriched Diet, Ipilimumab and Nivolumab in people with ICB-refractory Melanoma, run by M.D. Anderson Cancer Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 11 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall response rate (time frame: Up to 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Aug 2026.
