Green Tea and Quercetin in Combination with Docetaxel Chemotherapy in Castration-resistant Prostate Cancer Patients
Sponsor: Charles Drew University of Medicine and Science
ClinicalTrials ID:NCT06615752
This trial evaluates the safety and efficacy of green tea and quercetin with docetaxel in mCRPC patients. Participants must be adult males with progressive metastatic prostate cancer, adequate organ function, and a life expectancy of at least six months. They will receive either the supplement combination or a placebo with docetaxel. Compliance with study procedures and cessation of other tea products are required.

Program Overview
The goal of this clinical trial is to find out if taking natural products green tea and quercetin along with docetaxel chemotherapy improves the therapy of advanced prostate cancer, i.e., metastatic castration-resistant prostate cancer (mCRPC). It will also learn about the safety of this combination.
Researchers will compare green tea plus quercetin to a placebo (a look-alike substance that contains no drug) in combination with docetaxel to see if green tea and quercetin works to improve the therapeutic effect of docetaxel.
