Progesterone

Data Demonstrated Once-Weekly Milprosa™ Provides Similar Pregnancy Rates to Daily 8 Percent Progesterone Vaginal Gel

Mar 4, 2013 –

Teva Pharmaceutical Industries Ltd.  today announced the publication of results of the Phase III clinical trial of Milprosa™ (progesterone) vaginal ring in Fertility and Sterility. The study compared the efficacy and safety of once-weekly Milprosa™ to daily 8 percent progesterone vaginal gel for luteal phase support in in vitro fertilization (IVF) and found that clinical pregnancy rates per retrieval at eight and 12 weeks were comparable between patient groups. Adverse event (AE) profiles were similar between the two treatment groups and consistent with known AEs associated with progesterone.

“The study results demonstrate that Milprosa™ may be an effective and safe option for progesterone supplementation during the luteal phase among women undergoing IVF,” said Laurel Stadtmauer, M.D., Ph.D., professor of Obstetrics and Gynecology at Jones Institute for Reproductive Medicine at Eastern Virginia Medical School and study author. “Since normal luteal function may be compromised among women undergoing IVF, progesterone supplementation is essential and the more options patients have, the better. If approved, the once-weekly dosing of Milprosa™ may offer convenience for patients.”

The Phase III randomized, single-blinded, multicenter, noninferiority study was conducted at 22 clinical sites in the U.S. and included 1,297 patients between the ages of 18 and 42. Of enrolled patients, 646 were randomized to Milprosa™ and 651 to the 8 percent progesterone vaginal gel.

“The Fertility and Sterility publication of the Milprosa™ Phase III data is a significant milestone for Teva, especially because fertility is a meaningful new area of specialization for the company and one in which significant unmet need exists,” said Jill DeSimone, senior vice president & general manager, Global Teva Women’s Health. “We look forward to continuing to share important updates about Milprosa™ and demonstrating our investment in and commitment to women’s health.”

About the Study

The Phase III study randomized patients into two treatment groups: one group received once-weekly Milprosa™ and the other received daily 8 percent progesterone vaginal gel. Milprosa™ and the vaginal gel were initiated on the day following egg retrieval and continued through 12 weeks’ gestation. Efficacy was evaluated by comparing clinical pregnancy rates of patients at eight and 12 weeks gestation.

  • At week eight, clinical pregnancy rates per retrieval were 48.0 percent for the Milprosa™ group and 47.2 percent for the vaginal gel group (between-group difference, 0.8%; 95% CI, -4.6%, 6.3%).
  • At week 12, clinical pregnancy rates per retrieval for Milprosa™ and the vaginal gel were 46.4 percent and 45.2 percent respectively (between-group difference, 1.3%; 95% CI, -4.1%, 6.7%).

A secondary efficacy endpoint was the rate of live birth.

  • The overall live birth rate per retrieval for women using Milprosa™ was 45.2 percent; among women using the vaginal gel, the rate was 43.3 percent.
  • The majority of patients pregnant at week 12, when progesterone treatment ended, went on to have a live birth: 97.4 percent for the Milprosa™ group and 96.5 percent for the vaginal gel group.

The most commonly reported adverse events (those greater than or equal to 10% in the Milprosa™ treatment group) were nausea, headache, abdominal pain, post-procedural discomfort, abdominal distension, back pain, fatigue, vomiting and constipation. Serious adverse events (SAEs) occurred in approximately 12 percent of all patients, with no significant difference in the rate between treatment groups. The majority of SAEs that occurred were mild to moderate in severity and not related to treatment. Rates of discontinuation of treatment due to AEs were low and similar between both groups (approximately 6%).

About Milprosa™ (Progesterone) Vaginal Ring

Milprosa™ is an investigational, once-weekly progesterone ring inserted in the vagina. It is flexible and designed to continuously release a steady dose of micronized progesterone. Milprosa™ is in development to support embryo transplantation and early pregnancy (up to 10 weeks post-embryo transfer) by supplementation of corpus luteal function as part of an Assisted Reproductive Technology (ART) treatment program for infertile women.

About Supplementation of Corpus Luteal Function

The corpus luteum is a temporary endocrine gland that develops during the luteal phase of a woman’s menstrual cycle. It is an important contributor of progesterone and is critical for the maintenance of early pregnancy. During in vitro fertilization, progesterone supplementation is needed because natural levels of the hormone may be insufficient. This supplementation improves implantation rates and thus pregnancy rates. Additionally, progesterone supplementation supports early pregnancy.
