A Feasibility Study Evaluating a Role for Maintenance Therapy in Patients With Biochemically Progressive Castration Sensitive Prostate Cancer on Intermittent Androgen Deprivation Therapy

NCT06044025 · Status: RECRUITING · Phase: PHASE1 · Type: INTERVENTIONAL · Enrollment: 34

Last updated 2026-01-15

No results posted yet for this study

Summary

The goal of this clinical trial is to assess the feasibility of adding a combination of metformin and turmeric as part of a nutritional intervention regimen to the current standard of care, namely, intermittent Androgen Deprivation Therapy (iADT), for patients with castration sensitive biochemical progressive prostate cancer.

The main objectives are:

* Assess the feasibility of the study population and enrollment.
* Evaluate time to PSA relapse with nutritional intervention on iADT.

Participants who are receiving iADT will be dispensed Metformin and turmeric and complete a pill diary. Participants will also have blood and stool samples collected and complete quality of life questionnaires.

The long-term goal is to further assess the efficacy and safety of this nutritional regimen and the roles of metabolic syndrome, microenvironment/microbiome, and genomic vs epigenomic profiles in the care of these patients through a clinical trial.

Conditions

  • Castration Sensitive Prostate Cancer

Interventions

DRUG

Metformin

Subjects will start with metformin 500 mg by mouth (po) two times daily (bid) with meals for 14 days. Metformin titration will then increase to 850 milligram (mg) po bid for 14 days before increasing titration to a desired dosage of 1,000 mg po bid. For those subjects currently taking Metformin, they will continue current dose (if 1,000 mg po bid) or titrate dose as just described until maximum dose is achieved.

DRUG

Turmeric

Each subject will start with 1,500 mg turmeric po daily with meals. The dose can be temporarily reduced to 1,000 mg po daily for those who report GI discomfort. If GI discomfort has resolved within one month of the dose reduction, subjects will resume 1,500 mg po daily. If GI discomfort has not resolved or resumes at increased dose, the subject may be instructed to stop taking the study treatment and removed from the study.
