Positive results of E4 co-treatment with androgen deprivation therapy for advanced prostate cancer has been published in European Urology Open Science

Pantarhei Oncology proudly announces that its paper ‘Estetrol Cotreatment of Androgen Deprivation Therapy in Infiltrating or Metastatic, Castration-sensitive Prostate Cancer: A Randomized, Double-blind, Phase II Trial (PCombi)’ has been published in the journal European Urology Open Science after comprehensive review. This journal is an international peer-reviewed, scientific, open access journal in the field of urology.

The research paper reports the results of the PCombi study, a phase II, double-blind, randomised, placebo-controlled, multi-centre study in males recently diagnosed with locally advanced or metastatic prostate cancer, who started ADT treatment with an LHRH agonist. The ADT-treated patients were co-treated for 24-weeks with 40 mg E4 or placebo. The high dose E4 treatment was well-tolerated and no treatment-related cardiovascular adverse events were observed. Patient treated with E4 reported fewer complaints of estrogen deficiency symptoms and better quality of life than patients who received placebo. With E4, 6% of the patients reported hot flushes compared to 55% of patients treated with placebo. Total and free testosterone, prostate-specific antigen (PSA), and follicle-stimulating hormone (FSH) were suppressed more rapid and profound, suggesting enhanced disease control by E4. In addition, bone turnover was substantially reduced in the E4-treated patient implicating a bone-sparing effect. The study results have now been published in European Urology Open Science (EUROS).

Review paper on the risk of breast cancer in relation to gender, breast development and gonadal function published in JCEM

/in ,

The Journal of Clinical Endocrinology & Metabolism has accepted the manuscript “Breast Cancer and Major Deviations of Genetic and Gender-related Structures and Function” by Herjan J.T. Coelingh Bennink, Jan F.M. Egberts, Jan A. Mol, Kit C.B. Roes, Paul J. van Diest for publication. The review reports of the risk of breast cancer (BC) in relation to gender, breast development and gonadal function in eight populations with different genetic conditions. Main three conclusions are: 1) the presence of an Y chromosome protects against the development of BC; 2) Without menstrual cycles, BC hardly occurs with an incidence comparable to males; 3) BC has been reported only once in genetic females with the Mayer-Rokitansky-Küster-Hauser syndrome, who have normal breasts and ovulating ovaries with normal levels of estrogens and progesterone.

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

/in

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.
