Metabolic Interventions (Time-Restricted Eating, GLP1 Receptor Agonist, and Heart Healthy Diet) to Improve Cardiometabolic Health in Prostate Cancer Patients During Androgen Deprivation Therapy, IMPACT-ADT Trial

A Phase II Randomized Study of Interventions for Metabolic Protection Against Cardiometabolic Toxicity During Androgen Deprivation Therapy (IMPACT-ADT)

Metabolic Interventions (Time-Restricted Eating, GLP1 Receptor Agonist, and Heart Healthy Diet) to Improve Cardiometabolic Health in Prostate Cancer Patients During Androgen Deprivation Therapy, IMPACT-ADT Trial (NCT07202247) is a Phase 2 interventional studying Prostate Carcinoma and Recurrent Prostate Carcinoma, sponsored by City of Hope Medical Center. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.

About This Trial

This phase II trial compares the effect of time-restricted eating (TRE) and glucagon-like peptide-1 (GLP1) receptor agonists (RA), semaglutide and tirzepatide, to an American Heart Association (AHA) heart healthy diet (HHD) intervention on heart and blood vessel health (cardiovascular system) and how the body processes food for energy (metabolic system) in prostate cancer patients undergoing androgen deprivation therapy (ADT). Prostate cancer patients who are receiving hormonal therapy (ADT) are at an increased risk of cardiovascular disease. This is thought to be due to treatment-related metabolic changes which may result in increased weight, body fat, insulin resistance and an increased risk of heart attack, stroke or other heart and blood vessel problems. TRE (also known as intermittent fasting) is an eating plan that alternates between fasting and non-fasting periods. This approach limits calorie intake to a specific window of time each day. GLP1-RAs, semaglutide and tirzepatide are in a class of medications called incretin mimetics. They work by helping the pancreas to release the right amount of insulin when blood sugar levels are high. Insulin helps move sugar from the blood into other body tissues where it is used for energy. They also slow the movement of food through the stomach and may decrease appetite and cause weight loss. The AHA HHD guidelines may be an effective method to help people learn about following a heart healthy eating plan. This may lower their risk of cardiovascular disease. Metabolic interventions, TRE and GLP1-RA, may be more effective than an AHA HHD intervention alone in improving cardiovascular and metabolic health in prostate cancer patients undergoing ADT.

What Stage of Research Is This?

Phase 2 trials evaluate whether a treatment actually works against Prostate Carcinoma and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

Target enrollment of 60 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused Prostate Carcinoma subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.
