Mithra (Euronext Brussels: MITRA), a company dedicated to Women’s Health today announces that it has received an additional patent for Estelle® in Japan in the dysmenorrhea(1) indication. Estelle® is Mithra’s combined oral contraceptive (COC) candidate, composed of 15 mg Estetrol (E4) and 3 mg drospirenone (DRSP).
Mithra considers Japan as one of its priority target territories for Estelle®, mainly due to the attractively priced and quite large market profile. This additional patent opens the door for the dysmenorrhea market, which is four times larger than the contraceptive market, particularly thanks to the attractive reimbursement rate. Together, the contraception and dysmenorrhea markets in Japan account for at least EUR 270 million a year(2).
Mithra has already a business partner for the commercialization of Estelle® in Japan, but also in ASEAN where the contraception market represents about EUR 130 million a year. In August 2016, the Company has signed a 20-year exclusive license and supply agreement with Fuji Pharma, the Japanese leader in Women’s Health. The terms of the agreement include a down payment, milestone payments, recurring revenues based on minimum annual quantities (MAQ) and further sales-related royalties. This agreement represents a potential deal value of EUR 450 million over the period.
Consolidation of the IP Strategy
The issuance of this patent covering the management of dysmenorrhea extends Estelle's IP protection in Japan until 2037. In addition, Mithra will apply for a patent term extension based on its marketing authorization for Estelle® in Japan, which should extend the patent lifetime for a maximum of 5 years. This patent application covering dysmenorrhea has also been filed in about 20 countries, mainly in Asia and Latin America where the dysmenorrhea market is particularly attractive in terms of sales volume and pricing.
Mithra is continuously expanding and consolidating its Intellectual Property portfolio to further strengthen and extend the E4 intellectual property estate. This now contains 31 patent families filed across the world, ranging from the synthesis of Estetrol to its use in a wide range of indications, including among others, menopause, cancer treatment and neuroprotection.
François Fornieri, CEO Mithra Women’s Health, comments: "This new patent in Japan is crucial for the Estelle's commercialization strategy in this high potential market in volume and value, especially when considering the contraception and dysmenorrhea indications together. With our 31 patent families, we have built a very strong Intellectual Property protection around Estelle® and more broadly our portfolio of Estetrol-based products, securing our innovations from potential competitors in a large majority of countries around the world."
