Last patient out in the phase II PCombi study with Estetrol in patients with prostate cancer

On May 14, 2020, the last patient has had his last study visit for the phase IIa clinical study of Pantarhei assessing the efficacy and safety of the fetal estrogen estetrol (E4) in prostate cancer patients. The study, the PCombi study, is a double-blind, randomised, placebo-controlled, multi-centre study in patients treated with hormone therapy, an luteinising hormone-releasing hormone (LHRH) agonist, for their prostate cancer.

The main objectives of this study are to evaluate the additional effect of E4 on testosterone suppression by the LHRH agonist as well as the prevention and treatment of hypoestrogenic side effects (e.g. hot flushes) due to the concomitant suppression of estrogens.

First results are expected to be available by beginning of August this year.
