Investigation of Metformin in Patients With Castration Resistant Prostate Cancer in Combination With Enzalutamide vs. Enzalutamide Alone

Prostate Cancer Clinical Trial

Official title:
Investigation of Metformin in Patients With Castration Resistant Prostate Cancer in Combination With Enzalutamide vs. Enzalutamide Alone (IMPROVE TRIAL): A Randomized, Open Label, Phase II Trial

Clinical Trial Summary

The purpose of this trial is to test if the combination of enzalutamide and metformin in patients with castration resistant prostate cancer CRPC progressing on androgen deprivation therapy ADT is more effective compared to enzalutamide alone. The half of the patients will receive the experimental treatment combination, enzalutamide and metformin, while the other half will receive enzalutamide alone.

Clinical Trial Description

One in seven men will be diagnosed with cancer of the prostate during his lifetime . Accordingly, prostate cancer (PC) is the most common cancer amongst men in the western world and worldwide. PC ranks second in cancer incidence and sixth in cancer mortality in men. The current standard of care for patients with metastatic castration resistant prostate cancer (mCRPC) and disease progression is either treatment with abiraterone acetate and prednisone in asymptomatic or mildly symptomatic patients without visceral metastases, or treatment with docetaxel in more symptomatic patients and in the presence of visceral metastases. Rothemundt et al. previously demonstrated favorable effects of metformin in a phase II trial: it yields objective Prostate specific antigen PSA responses and may induce disease stabilization and improve metabolic endpoints in patients with CRPC. Therefore addition of metformin to enzalutamide might have positive impact on tumor progression, on body composition, and insulin sensitivity. ;
