About this study

Official title: Txt4fasting: An Interactive Mobile Time-Restricted Eating Diet Intervention for Patients With Brain Metastases to Maximize Radiation Outcomes

This clinical trial tests the effectiveness of an interactive time-restricted diet intervention (txt4fasting) in reducing neurocognitive decline and improving survival outcomes after stereotactic radiosurgery in patients with breast or lung cancer that has spread to the brain (brain metastases). Lung cancer and breast cancer are the two most frequent causes of brain metastases. The diagnosis of brain metastases is associated with poorer survival and tumor-induced and treatment-related side effects. Stereotactic radiosurgery is a type of external radiation therapy that uses special equipment to position the patient and precisely give a single large dose of radiation to a tumor. Patients who receive stereotactic radiosurgery for brain metastases may experience less neurocognitive side effects than with other types of brain radiation, but may still be at risk for their brain metastases growing, spreading, or getting worse. Patients with obesity and diabetes have been shown to have worse survival and increased radiation-related side effects. Evidence demonstrates that simply changing meal timing can have a positive impact on multiple health outcomes. Time-restricted eating, or prolonged nighttime fasting, has been proven to have positive effects on heart disease risk reduction, weight control management and chemotherapy side effect reduction. Txt4fasting may be effective in decreasing neurocognitive decline and improving survival outcomes in patients undergoing stereotactic radiosurgery for brain metastases from breast or lung cancer.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To examine the feasibility and acceptability of the txt4fasting intervention.

SECONDARY OBJECTIVES:

  1. To compare neurocognitive function decline between the intervention and the control arms.

II. To compare progression free survival (PFS) between the intervention and the control arms.

TERTIARY (EXPLORATORY) OBJECTIVE:

  1. To evaluate the change in biomarkers, from baseline to the end of the study, between the intervention and the control arms.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients follow a time-restricted diet, receive interactive positive reinforcement messages, and record food intake using the txt4fasting platform daily for 30 days. Patients receive counseling calls twice weekly in weeks 1 and 2 then once weekly in weeks 3 and 4. Patients then undergo stereostactic radiosurgery (SRS) on study. Patients also undergo blood sample collection and brain magnetic resonance imaging (MRI) throughout study.

ARM II: Patients receive text messages about healthy eating habits and food suggestions twice daily and record food intake using txt4fasting program for 30 days. Patients then undergo SRS on study. Patients also undergo blood sample collection and brain MRI throughout study.

After completion of study intervention, patients are followed up immediately at the end of the intervention, and at 3 and 6 months.

What is being measured

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

  1. Accrual rate

    Feasibility will be defined as 70% of eligible patients reached consent and enroll. Accrual rate will be summarized using percentage and 95% exact confidence intervals.

    Measured: Up to 5 years

  2. Attrition rate

    Feasibility will be defined as 70% of enrolled participants complete post-intervention follow-up. Attrition rate will be summarized using percentage and 95% exact confidence intervals.

    Measured: Up to 6 months post intervention

  3. Time-restricted eating (TRE) compliance rate

    Feasibility will be defined as 70% of participants are compliant with 70% of the intervention days with suggested TRE. TRE compliance rate will be summarized using percentage and 95% exact confidence intervals.

    Measured: Up to 6 months post intervention

  4. Incidence of adverse effects (AEs)

    AEs will be graded for severity according to the Common Terminology Criteria for Adverse Events.

    Measured: Up to 6 months post intervention

  5. Patient satisfaction

    Acceptability will be measured through a validated treatment satisfaction measure and patient interview data. Acceptability will be established by a group median score ≥ 28 on the Coping Strategies Questionnaire-837. Patient satisfaction will be summarized using percentage and 95% exact confidence intervals.

    Measured: Up to 6 months post intervention

Secondary outcomes (5)
  1. Neurocognitive function decline

    Neurocognitive function decline will be measured on the Cambridge Neuropsychological Test Automated Battery.

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 9 inclusion and 5 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: stopped early, as of the sponsor's last update on 3 Mar 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.

Are results available for this study?

The study was stopped early (reason given: slow accrual). Results are not available in the source record.

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?

Accrual rate (time frame: Up to 5 years). The study lists 5 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 3 Mar 2026.
