FYLREVY® is approved as HRT for oestrogen deficiency symptoms in non-hysterectomised postmenopausal women with at least 12 months since last menses (FYLREVY® 14.2 mg and 18.9 mg) and as HRT for oestrogen deficiency symptoms in hysterectomized postmenopausal women (FYLREVY® 18.9 mg).
“Advancing innovation in menopause marks an important milestone in our long‑standing commitment to women’s healthcare. Despite the significant burden that postmenopausal symptoms place on millions of women worldwide, therapeutic progress in this field has remained limited for decades. With the recent EC approval for FYLREVY® – our second product based on the unique, proprietary Estetrol (E4) platform –, we aim to bring an original, science‑driven solution to a condition that continues to be vastly underserved today. Accordingly, launching FYLREVY® from the second half of 2026 will be a key priority project for Richter” – said Dr. Péter Turek, Head of Women’s Healthcare (WHC) Business Unit.
About FYLREVY®
The orally administered Estetrol-based oestrogen therapy FYLREVY® is designed to treat the broad spectrum of oestrogen deficiency symptoms in postmenopausal women, including VMS. Estetrol (E4) is a native oestrogen produced by the foetal liver during pregnancy and is synthesized from plant sources for pharmaceutical purposes. Preclinical and clinical data for E4 points to a tissue-specific activity and a more selective pharmacological profile compared to other estrogens, including a low impact on the liver, hemostasis balance and breast cell proliferation. The efficacy and safety of E4 in alleviating VMS was evaluated in two independent, confirmatory, pivotal phase 3 studies (E4COMFORT I and E4COMFORT II) having enrolled a total of 2576 postmenopausal women in Europe, Russia, United States of America (USA), Canada and Latin America. In addition to its authorization in over 50 countries worldwide as the oestrogen component of a combined oral contraceptive with drospirerone (marketed as DROVELIS® in EU), E4 is now further expanding its therapeutic reach in the menopause field.
About Menopause
Menopause is a natural biological process marking the end of a woman's reproductive years, typically occurring between 45 and 55 years old. It is characterized by the cessation of menstruation due to decreased production of oestrogens and progesterone by the ovaries.
The most frequently reported symptoms include vasomotor symptoms (VMS, which include hot flushes and night sweats), vulvo-vaginal atrophy (VVA), sleep disturbances, impaired bone health, physical changes (amongst which musculoskeletal symptoms, weight gain, thinning hair and dry skin), mood changes (including increased irritability, anxiety and depression), urinary incontinence, and cognitive changes.
VMS are among the most common and bothersome menopausal complaints, and one of the main reasons why women may seek medical care for the menopause. Hot flushes are characterized by sudden sensations of heat in the upper body, that last for 2 to 4 minutes and repeat multiple times each day. Up to 80% of menopausal women suffer from VMS, which have a mean duration of 7 to 9 years.
