Mithra and Mayne Pharma’s Vaginal Contraceptive Ring Accepted for Filing by FDA


Mithra (Euronext Brussels: MITRA), a company dedicated to Women’s Health, is pleased to announce that the Abbreviated New Drug Application (ANDA) for its vaginal ring for contraception has been accepted for filing by the US Food and Drug Administration (FDA). The ANDA has been submitted by Mithra’s partner for the US commercialization of the vaginal ring, Mayne Pharma (ASX: MYX). The acceptance by the FDA is an important regulatory step, as it reconfirms the pathway towards launch of the product candidate in H1 2019.

The vaginal ring product candidate, Myring™1 , is an intra-vaginal hormonal contraceptive delivery device combining etonogestrel and ethinyl estradiol over a 3-week period, and is developed to be fully bioequivalent to Merck’s Nuvaring®. NuvaRing® had total US sales of approximately USD 830 million for the 12 months ending 31 January 20183
. The US market represents over 75% of the annual global sales of Nuvaring®, making this a key territory for the product. Nuvaring® will go off patent in April 2018, and no generic version has been approved in the US to date. 

The exclusive long-term license and supply agreement with Mayne Pharma was announced in 2017, and next to a EUR 2.4 million down payment received, Mithra is eligible for further milestones of at least EUR 7.6 million from approval by the US FDA through to commercial launch of the product. Following launch, Mithra is anticipating important financial contributions from the production of the vaginal ring at the Mithra CDMO.

In 2017 and early 2018, Mithra also closed European contracts for its vaginal contraception ring with Gynial, Adamed and Alvogen for the Austrian, Czech and Russian market, respectively. 

François Fornieri, CEO Mithra Women’s Health: “We are very pleased that our partner Mayne Pharma has received filing acceptance from the FDA for our vaginal ring. This important regulatory milestone underlines the dedication and know-how of the Mayne Pharma team to bring the ring to market. Mayne Pharma remains on track to launch the ring in H1 2019, and we expect the production of the ring to contribute significantly to our revenues at the level of the Mithra CDMO”.


About Myring™1
Myring™ is developed to be a generic of Nuvaring® vaginal ring, still under patent protection up to April 2018 both in the US and in the EU. Myring™ (etonogestrel/ethinyl estradiol vaginal ring) is a nonbiodegradable, flexible, transparent, combination contraceptive vaginal ring, with an outer diameter of 54 mm and a cross-sectional diameter of 4 mm. It is made of ethylene vinylacetate copolymers, and contains 11.7 mg etonogestrel and 2.7 mg ethinyl estradiol. When placed in the vagina, each ring releases, as originator product Nuvaring®, on average 0.120 mg/day of etonogestrel and 0.015 mg/day of ethinyl estradiol over a three-week period of use. The ring is to remain in place continuously for three weeks. It is removed for a one-week break, during which a withdrawal bleed usually occurs. A new ring is inserted one week after the last ring was removed.
