tranScrip is thrilled to be working with Mithra Pharmaceuticals (Mithra), who has announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion for Estelle®, Mithra’s novel combined oral contraceptive (COC), containing 15 mg Estetrol (E4), a unique native oestrogen and 3 mg drospirenone (DRSP). This announcement follows the positive response from Health Canada who last week gave the first in the world regulatory approval of Estelle®.
The E4 containing COC approval represents a significant milestone in women’s health. E4 is a naturally occurring oestrogen produced in the human body, with a unique mechanism of action that displays oestrogen receptor selective activity. E4 shows agonist activity on the vagina, the uterus and the endometrium, the bones and the brain, and antagonistic activity in breast tissue. It has neutral impact on lipids and its distinct metabolic and haemostatic profile provide further differentiation based on its unique mechanism of action. The first regulatory approval granted worldwide for Estelle® is a significant milestone in the E4 development programme and in treatments for women’s health.
tranScrip is supporting Mithra’s E4 COVID-19 research programme, now in Phase 2. Oestrogen has been proposed as a potential broad-spectrum treatment against respiratory viral disease following pharmacological studies (Mauvais-Jarvis, Klein, and Levin 2020) and epidemiological studies showed reduced COVID-19 mortality in women taking hormone replacement therapy (Seeland et al. 2020; Dambha-Miller et al. 2021). As a unique selective oestrogen, E4 is a potential candidate for managing respiratory viral disease, including COVID-19.
