About this study

Official title: Phase 2, Single Arm Study to Evaluate the Efficacy of Time Restricted Eating (TRE) on Immunotherapy Treatment Outcomes in Patients With Metastatic Head and Neck Squamous Cell Cancer (mHNSCC) or Unresectable or Metastatic Renal Cell Carcinoma (RCC)

The purpose of this study is to evaluate whether Time Restricted Eating (TRE) can improve responses in participants with metastatic head and neck squamous cell cancer (mHNSCC) or unresectable/metastatic renal cell carcinoma (RCC) receiving Immune Checkpoint Blockers (ICB) by changing the gut microbiome (the bacteria and other microorganisms living in individual's bodies). A particular focus of this study is to compare the outcomes of African American participants when compared to the rest of the participant population. TRE is a form of intermittent fasting where food and drink intake is limited to a specific time window during the day. The information learned from this study may help researchers develop new strategies to improve outcomes in patients with mHNSCC and RCC in the future.

Participants will be asked to complete a dietary survey at baseline and week 9 and provide a baseline stool and blood sample. Two weeks before beginning ICB and after participants completed the baseline assessments, they will begin TRE. TRE will be defined as limiting food and drink intake to a 10 hour window during each day and fasting for 14 hours at night. Participants will be asked to complete a daily food log to document the times they eat and drink. On day 1 of ICB and weeks 3, 6, 9, 26, and 52 after ICB, participants will be asked to collect a blood sample and a toxicity assessment will be performed. On day 1 of ICB and weeks 9, 26, and 52 of ICB, participants will be asked to provide a stool sample. Participants will also undergo tumor imaging throughout the study as part of their standard of care assessments. If a participant's disease progresses after ICB, they will repeat all study assessments and be withdrawn from the study.

What is being measured

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

  1. Median progression free survival (PFS) for HNSCC cohort only

    Time from enrollment to radiographic disease progression as per RECIST 1.1 or death from any cause

    Measured: 1 Year

  2. Time restricted eating (TRE) associated change in gut microbiome

    Microbiome changes in stool

    Measured: Baseline, Day 1, Week 9, Week 26 and Week 52

  3. Time restricted eating (TRE) associated change in metabolome

    Metabolomics in blood

    Measured: Baseline, Day 1, Week 9, Week 26 and Week 52

  4. Time restricted eating (TRE) associated change in IGF1

    IGF1 level in blood

    Measured: Baseline, Day 1, Week 9, Week 26 and Week 52

  5. Time restricted eating (TRE) associated change in immune repertoire

    Comprehensive analysis of effector T cells and suppressor T cell populations in PBMC, plasma cytokines will be carried out

    Measured: Baseline, Day 1, Week 9, Week 26 and Week 52

  6. Response to immune checkpoint blocker (ICB) at first response assessment

    Radiographic response as per RECIST 1.1

    Measured: Week 9

Secondary outcomes (4)
  1. 1-year immune related adverse events (irAE) rate

    1 year rate of irAE, as per CTCAE v.5

    Measured: 1 Year

  2. Feasibility of Time restricted eating (TRE) in African American HNSCC participants on immune checkpoint blocker (ICB)

    Number of African American participants who were compliant, which is defined as 14 hr TRE daily for 5 days per week, for 9 out of first 12 weeks (70%)

    Measured: Through Week 52

  3. 1-year immune related adverse events (irAE) rate in African American participants

    1 year rate of irAE, as per CTCAE v.5 in African American participants

    Measured: 1 year

  4. Median progression free survival (PFS) for RCC cohort only

    Time from enrollment to radiographic disease progression as per RECIST 1.1 or death from any cause

    Measured: 1 Year

Questions about this trial

What is this clinical trial studying?

A study testing Time restricted eating (TRE) in people with Metastatic Head-and-neck Squamous-cell Carcinoma and Unresectable Renal Cell Carcinoma, run by Duke University 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 8 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: withdrawn, as of the sponsor's last update on 19 Dec 2025. 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.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Median progression free survival (PFS) for HNSCC cohort only (time frame: 1 Year). The study lists 6 primary outcomes in all. 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 19 Dec 2025.
