Mayne Pharma Submits New Drug Application for E4/DRSP to the FDA

ADELAIDE, Australia and LIEGE, Belgium, April 16, 2020 /PRNewswire/ -- Mayne Pharma Group Limited (ASX: MYX) and Mithra Pharmaceuticals, SA (Euronext Brussels: MITRA) today announced that Mayne Pharma has submitted a New Drug Application (NDA) to the US Food and Drug Administration (FDA), seeking marketing authorisation for E4/DRSP, a combined oral contraceptive indicated for the prevention of pregnancy. If approved by the FDA, E4/DRSP is expected to be made available to patients in the US market in the first half of calendar 2021.

E4/DRSP is a novel, next generation oral contraceptive containing Estetrol (E4) 15 mg and drospirenone (DRSP) 3 mg. E4 is a naturally occurring estrogen that is produced by the human fetal 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.

US sales of combined hormonal contraceptives are more than US$4 billion per annum, according to IQVIA with 10 million American women using combination (estrogen + progestin) oral pills, patches or vaginal rings each day[1]. 

Mitchell Creinin, Professor and Director of Family Planning at the University of California, Davis said, "I am excited to see the overall results for E4/DRSP from two phase 3 clinical studies including more than 4,400 women around the world that demonstrated very positive outcomes for efficacy and safety in a product that achieved a desirable bleeding profile and excellent tolerability."

Mayne Pharma's CEO Scott Richards said, "The NDA filing is a major milestone for Mayne Pharma and our development partner Mithra Pharmaceuticals. We are now one step closer to making this new oral contraceptive that we believe to be safe, effective and well-tolerated available to American women. We confirm our earlier stated goal of bringing this product to market in the first half of calendar 2021." 

Mithra's CEO Francois Fornieri said, "We are very proud of this key milestone for the commercialisation of our first blockbuster candidate in the world's largest pharmaceutical market. E4/DRSP is now filed in the US and Europe and we are actively working with our partners for the commercial launch of this product around the world. E4/DRSP promises to provide women with a new choice in oral contraception, in a space where there hasn't been any new innovative hormones introduced for many decades."
