Mithra announced there will be four presentations on Estetrol (E4) native estrogen at the North American Menopause Society (NAMS) 2023 Annual Meeting, being held September 27-30 in Philadelphia, USA. E4 is a key active pharmaceutical ingredient in both Mithra?s marketed contraceptive Estelle® and its next generation hormone therapy product candidate for postmenopausal symptoms, Donesta®. Amanda Black MD, MPH, FRCSC, Professor of Obstetrics and Gynecology at The University of Ottawa, will hold an independent oral presentation on the use of E4 for contraception and menopause.

Dr. Black will be discussing the science and safety behind the use of E4 in the menopause at the opening symposium and will present some of the data on the effects of E4 on breast tissue. Dr. Wulf Utian, MD, PhD, DSc, Executive Director Emeritus and Honorary Founding President of NAMS, who is considered to be one of the world?s authorities on menopause and women?s health, will hold an oral presentation on the Phase 3 results of E4 in postmenopausal symptoms. The data, from two multi-center, double-blind, placebo-controlled trials with 2,550 postmenopausal women aged 40-65, show beneficial effects from 12-week treatment with E4. These include a significant increase in high-density lipoprotein (HDL) ?

or ?good? ? cholesterol and a significant decrease in the ratio total of HDL cholesterol to low-density lipoprotein (LDL) ?bad?

cholesterol and lipoprotein. There was also a significant decrease in fasting plasma glucose and HbA1c average blood glucose (glycemia) level. Also observed were trends for decreases in insulin and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR).

Dr. Black and Dr. Utian will each also hold poster presentations on E4 at NAMS 2023. Mithra has previously reported positive results from Phase 3 trials, showing strong efficacy and a favorable safety profile for contraception, for Estelle®, and separately, a statistically significant reduction in vasomotor symptoms, or hot flushes and night sweats, in postmenopausal women, with Donesta®.
