Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adult males aged 18 and older with a histologic diagnosis of prostate cancer who are eligible for radical prostatectomy.
✕Probably not a fit
Patients with prior malignancies or those who have received recent cancer treatments may not benefit from this study.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This pilot, randomized trial investigates the effects of Glycyrrhizin (GLY) on patients with untreated prostate cancer who are candidates for radical prostatectomy. Participants will receive one cycle of therapy with either 75mg or 150mg of Glycyrrhizin daily for six weeks prior to their surgery. The study aims to assess the safety and efficacy of this treatment approach in a window-of-opportunity setting. The trial will include a control group receiving observation to compare outcomes.
Why it matters
Potential benefit: If successful, this treatment could improve surgical outcomes and overall management of prostate cancer.
How similar studies have gone: While Glycyrrhizin has been studied in other contexts, this specific approach in prostate cancer is novel and has not been extensively tested.
