Lotus Pharmaceutical Co., Ltd. (TWSE: 1795, “Lotus”) and Mithra Pharmaceuticals, SA (Euronext Brussels: MITRA, “Mithra”) today are pleased to announce that Estelle® , the first-of-its-kind oral contraceptive with a novel estrogen developed by Mithra, has been approved by both Taiwan Food and Drug Administration (TFDA) and Hong Kong Drug Office, Department of Health, under the trademark ALYSSA®. Through this partnership with Mithra, Lotus will be exclusively marketing the product in Taiwan and Hong Kong.

Already commercialized globally, including major markets such as the US, Canada, Australia and several European countries, ALYSSA® is the first ever oral contraceptive pill to combine the native and selective estrogen, estetrol (E4) with drospirenone (DRSP). E4 is a naturally occurring estrogen produced by the human body during pregnancy, and, in ALYSSA® , E4 is derived from a plant source. Thanks to E4’s unique pharmacologic profile and mechanism of action, ALYSSA® has been specifically designed to help overcome the issues associated with synthetic or modified estrogen-based COCs.

Upon launch, ALYSSA® will compete in the Taiwanese oral contraceptive market which was valued at US$14million (1) in 2021 and currently mainly dominated in Taiwan by ethinyl estradiolbased estrogen solutions. Lotus will also market the product in Hong Kong to capture the market potential of approximately US$11 (2) million as of 2021.

Petar Vazharov, Chief Executive Officer of Lotus, commented: “We are very excited about our partnership with Mithra to introduce a novel oral contraceptive in Taiwan and Hong Kong markets. Within our existing women healthcare portfolio, the approval of ALYSSA® represents an important milestone in providing women with new generation options for their reproductive health. ALYSSA® offers an effective, safe, and well-tolerated contraceptive pill with predictable cycle control and has demonstrated low impact on certain parts of the body.”

Leon Van Rompay, CEO Mithra Women’s Health, commented: “We are pleased to share the approval received by our partner Lotus for our Estelle® contraceptive in both Taiwan and Hong Kong, which marks our first authorization on the Asian continent. After successfully launching Estelle® in the United States, Canada, Australia and in Europe, these upcoming launches in these two markets further demonstrate Mithra’s ability to pursue Estelle® 's business development with best-in-class partners in core territories. Therefore, we are proud to, jointly with Lotus, continue revolutionizing the contraceptive landscape by offering Taiwanese and Hong Kongese women an alternative solution with an optimal benefit/risk.”
