Mithra Announces Positive Outcome of Myring™ Commercial Batch Bioequivalence Study

 

Mithra (Euronext Brussels: MITRA), a company specialized in Women’s Health, announces the successful outcome of a confirmatory bioequivalence study performed on a commercial batch of Myring™ produced at the Mithra CDMO. The study results reconfirm that Myring™ is bioequivalent to Nuvaring®, a combined hormonal contraceptive vaginal ring made of ethylene vinyl acetate copolymers (EVA).

The study was performed following the tech transfer of Myring™ to Mithra’s CDMO facility in early 2017. Mayne Pharma, Mithra’s US partner, is progressing regulatory preparations to ensure a timely submission to FDA in the next few months, and correspondingly efficient approval and commercial launch timelines for Myring™. As a reminder, in February 2017, Mithra closed a 10-year exclusive LSA with Mayne Pharma for an upfront of EUR 2.4 million, milestones of at least EUR 10 million following FDA approval and important revenues based on the minimal annual quantities and manufacturing forecasts at the Mithra CDMO. The global market for Nuvaring® amounts to approximately USD 970 million (CAGR: 7.1%), with nearly 80% of sales in the US2, making this a key territory for Myring™.


These latest bioequivalence data will also be used to supplement the Myring™ European marketing approval application (MAA), which was already submitted to the European authorities in July 2017. In May 2017, Mithra received Good Manufacturing Practice (GMP) approval for the production line of Myring™ at the Mithra CDMO.

François Fornieri, CEO of Mithra, commented:

“We are very pleased with the results of the commercial production bioequivalence study, which confirms the previously generated bioequivalence data and demonstratesthe expertise of our R&D and CDMO team. With today’s results, our US partner Mayne Pharma can prepare for FDA submission based on a very extensive file, which may allow for a swift approval and market launch in this important territory.”

About Myring™
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 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, in line with the originator (Nuvaring®), on average 0.120 mg/day of etonogestrel and 0.015mg/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.
