Population Council and Duchesnay Announce New International License Agreement for ANNOVERA®

NEW YORK, NY and BLAINVILLE, CANADA – November 30, 2020. Today the Population Council and Duchesnay announce an exclusive license agreement to make ANNOVERA® (segesterone acetate and ethinyl estradiol vaginal system), the first and only contraceptive fully under a woman’s control to protect against unintended pregnancy for up to a year, available in Canada, Europe, Latin America, Asia and other territories. This agreement is another step toward bringing contraceptive choice, convenience and control to women around the world.

ANNOVERA is the first in a new class of contraceptives. It is a soft reusable flexible silicone ring that combines a novel progestin Nestorone® (segesterone acetate) with a widely used estrogen (ethinyl estradiol), that can be inserted and removed by a woman herself. ANNOVERA was approved by the U.S. Food and Drug Administration (FDA) in August 2018 and is now available to women in the United States. 

“A lack of longer-lasting, women-controlled contraceptives means too many women who want to avoid pregnancy either don’t use, or stop using, contraception, leading to more unintended pregnancies and worse health outcomes,” said Jim Sailer, vice president and executive director of the Center for Biomedical Research at the Population Council. “This agreement will now open up opportunities to bring ANNOVERA to women on four continents—it’s another step forward in ensuring that women around the world have the contraceptive choices they deserve.”

ANNOVERA was developed by the Population Council and supported by important public and private donors from around the world, including the United States Agency for International Development (USAID), The Contraceptive Clinical Trials Network of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), the Bill & Melinda Gates Foundation, the Avis and Clifford Barrus Medical Foundation and the World Health Organization (WHO).

As part of the agreement, Duchesnay will explore opportunities to register ANNOVERA with local regulatory agencies in these regions and will invest in the Population Council’s research activities to develop new innovative contraceptive products.

“We are very excited to be a part of the Population Council’s efforts to bring important new contraceptive options to women around the world. As a company committed to improving women’s health, we believe that women deserve access to a wide variety of innovative contraceptive options such as ANNOVERA giving them full control of their lives,” said Eric Gervais, executive vice president at Duchesnay.
