ADELAIDE, Australia, June 24, 2020 /PRNewswire/ -- Mayne Pharma Group Limited (ASX: MYX) is pleased to announce the New Drug Application (NDA) for E4/DRSP to prevent pregnancy has been accepted for review by the US Food and Drug Administration (FDA). The FDA is expected to complete its review in the first half of calendar 2021.
Developed by Mithra Pharmaceuticals SA (Mithra), E4/DRSP is a novel combined oral contraceptive pill containing 15 mg estetrol (E4) and 3 mg drospirenone (DRSP). E4 is a naturally occurring estrogen that is produced by the human foetal liver during pregnancy. Following more than 20 years of research and development, Mayne Pharma's development and manufacturing partner, Mithra, can synthesise E4 at scale through a complex plant-based production process.
The NDA submission includes results from two phase 3 clinical studies conducted in more than 3,725 women aged 16 to 50 years.
If approved, E4/DRSP would be the first contraceptive product containing E4 and the first new estrogen introduced in the US for contraceptive use in approximately 50 years. US sales of combined hormonal contraceptives are more than US$4 billion per annum, with 10 million US women using combination (estrogen + progestin) oral pills, patches or vaginal rings[1].
Mayne Pharma's CEO Scott Richards said, "This is another important milestone for E4/DRSP and brings us one step closer to providing women in the US with a new contraceptive that we believe will be effective, safe and well-tolerated. We look forward to working with the FDA and Mithra during the ongoing review of our application. In parallel, we continue to advance our US commercial strategy and infrastructure to ensure we are well positioned to support the potential launch of E4/DRSP in the first half of calendar 2021."
Mayne Pharma recently extended its strategic relationship with Mithra to also bring E4/DRSP to the Australian market and plans to file the product with the Therapeutic Goods Administration (TGA) this calendar year.
