About this study

Official title: Fasting Mimicking Diet in Prostate Cancer and Metabolic Syndrome, a Pilot Study

This is a prospective observational cohort study of patients with prostate cancer who have a metabolic syndrome. The study aims to evaluate the role of intermittent fasting (fasting mimicking diet) in these patients. The primary end point is metabolic health and the secondary endpoint is quality of life.

Read the detailed description

Cancer is a complex set of conditions which collectively comprise the second biggest cause of death in the western world. In addition, these diseases, along with their various treatments, are associated with significant illness, as well as a host of debilitating symptoms. Two very common problems are cancer fatigue, as well as metabolic changes which can cause much suffering in and of themselves. Patients with advanced cancers, as well as many patients undergoing surgery, radiation therapy as well as chemotherapy all complain of fatigue, to a greater or lesser extent. Many gain or lose weight, and develop associated metabolic changes in uninvolved body systems, which can cause a significant health burden on the patients, as well as the healthcare system as a whole.

Little is known about the mechanisms which underlie these symptoms. Various biologic processes have been implicated including inflammation and other changes in body metabolism. There is urgent need to better understand these processes, which cause so much suffering in cancer patients, so as to potentially develop more effective solutions.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Fasting mimicking dietOther

    Also called Programmed cyclic nutrition for 3 monthly cycles (fasting mimicking diet)

    3 cycles of programmed nutrition using a fasting mimicking diet (Chemolieve (R)), each cycle consisting of 4 days. Pre and post nutritional cycles, clinical and metabolic assessments are taken, as per protocol. Allowing for a 3 month "washout" time, the 'post' assessment is planned approximately 6 months from the initial (pre) assessment.

What is being measured

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

  1. Change in Baseline Weight (in kilograms) at 6 months

    Metabolic health parameter

    Measured: Baseline and 3 months after Nutritional Cycle 3 (each cycle is 4 days per month), about 6 months

  2. Change in Baseline Blood Pressure (in millimeters of Mercury) at 6 months

    Metabolic health parameter

    Measured: Baseline and 3 months after Nutritional Cycle 3 (each cycle is 4 days per month), about 6 months

  3. Change in Baseline Waist Circumference (in centimeters) at 6 months

    Metabolic health parameter

    Measured: Baseline and 3 months after Nutritional Cycle 3 (each cycle is 4 days per month), about 6 months

  4. Change in Baseline Triglycerides Level (in millimoles per litre) at 6 months

    Clinical lab results

    Measured: Baseline and 3 months after Nutritional Cycle 3 (each cycle is 4 days per month), about 6 months

  5. Change in Baseline Total, LDL, and HDL Cholesterol (in millimoles per litre) at 6 months

    Clinical lab results

    Measured: Baseline and 3 months after Nutritional Cycle 3 (each cycle is 4 days per month), about 6 months

Secondary outcomes (3)
  1. Change in Baseline EQ5D5L Health Questionnaire Score at 6 months

    Structured Quality of Life Measure - Patients' self report of mobility, self-care, usual activities, pain/discomfort, anxiety/depression -

    1. No problem
    2. Slight problems
    3. Moderate problems
    4. Severe problems
    5. Unable to/extreme problems
    • 5 questions
    • Minimum score of 0, meaning good quality of life
    • Maximum score of 25, meaning poor quality of life

    Measured: Baseline and 3 months after Nutritional Cycle 3 (each cycle is 4 days per month), about 6 months

  2. Change in Baseline EQ5D5L Vertical Visual Analogue Scale Score at 6 months

    Structured Quality of Life Measure - Patients' self report on how good/bad their health is TODAY -

    • One scale numbered from 0 to 100
    • Minimum score of 0, meaning the worst health you can imagine
    • Maximum score of 100, meaning the best health you can imagine

    Measured: Baseline and 3 months after Nutritional Cycle 3 (each cycle is 4 days per month), about 6 months

  3. Change in Baseline Chalder Fatigue Index Score at 6 months

    Structured Tiredness/Fatigue Measures on Likert Scale - Patients' self report of fatigue symptoms -

    0: Less than usual

    1. No more than usual
    2. More than usual
    3. Much more than usual
    • 6 questions
    • minimum score of 0, meaning no fatigue due to illness
    • maximum score of 18, meaning chronic fatigue due to illness

    Measured: Baseline and 3 months after Nutritional Cycle 3 (each cycle is 4 days per month), about 6 months

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?

Change in Baseline Weight (in kilograms) at 6 months (time frame: Baseline and 3 months after Nutritional Cycle 3 (each cycle is 4 days per month), about 6 months). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.
