Menopause Publishes Pivotal Trial Results for Brisdelle™ (Paroxetine) Capsules, an FDA-Approved Non-Hormonal Therapy for Vasomotor Symptoms Associated with Menopause
MIAMI, FL and NEW YORK, NY, Sept. 18, 2013 /PRNewswire/ -- Noven Pharmaceuticals, Inc., today announced the publication of results from its two Phase 3 clinical studies in Menopause, the peer-reviewed, scientific journal of The North American Menopause Society. Brisdelle™, paroxetine capsules, 7.5 mg/day, was approved by the United States Food and Drug Administration in June 2013, for the treatment of moderate to severe vasomotor symptoms (VMS) associated with menopause, commonly referred to as hot flashes and night sweats. Brisdelle™ was specifically developed for and studied in women who experience moderate to severe VMS and is the first and only FDA-approved non-hormonal therapy clinically proven to treat moderate to severe VMS. Brisdelle™ will be available in pharmacies beginning November 2013.
"The publication of these data is timely and important because approximately 24 million women in the U.S. are affected by moderate to severe hot flashes and night sweats, yet two-thirds are not currently being treated," said Joel Lippman, M.D., FACOG, Noven's Executive Vice President – Product Development and Chief Medical Officer. "Prior to the approval of Brisdelle, physicians did not have a clinically proven and FDA-approved, non-hormonal treatment option to offer women."
Menopause published the 12-week and the 24-week multicenter, double-blind, randomized, placebo-controlled Phase 3 clinical studies evaluating Brisdelle™ for the treatment of moderate to severe vasomotor symptoms (VMS) associated with menopause. The co-primary endpoints of the studies evaluated weekly reductions in the frequency and severity of VMS associated with menopause in patients taking Brisdelle™ versus placebo at Week 4 and Week 12. Persistence of treatment benefit was also evaluated at 24 weeks in the 24-week study.
Brisdelle™ was studied in one Phase 2 and two Phase 3 randomized, placebo-controlled trials in 1,276 women with moderate to severe VMS associated with menopause and clinically proven to reduce the frequency and severity of hot flashes and night sweats. The most common adverse reactions, defined as those experienced by at least 2 percent of patients taking Brisdelle™ compared to placebo were headache (6.3 vs. 4.8 percent), fatigue/malaise/lethargy (4.9 vs. 2.8 percent) and nausea/vomiting (4.3 vs. 2.3 percent). Brisdelle™ has similar warnings and precautions to the higher doses of paroxetine used to treat a number of psychiatric disorders, including a Boxed Warning about Suicidal Thoughts or Behaviors. The lower dose of paroxetine in Brisdelle™ has not been studied in any psychiatric conditions and Brisdelle™ is not approved for any psychiatric uses.
About the Studies
Effect of Treatment on VMS Frequency and Severity
In the 12-week study, mean weekly reductions in VMS frequency were significantly greater for Brisdelle™ than for placebo at Week 4 (–33.0 and –23.5, respectively; p < 0.0001) and at Week 12 (–43.5 and –37.3, respectively; p = 0.0090). In the 24-week study, mean weekly reductions in VMS frequency were significantly greater for Brisdelle™ than for placebo at Week 4 (–28.9 and –19.0, respectively; p < 0.0001) and at Week 12 (–37.2 and –27.6, respectively; p = 0.0001).
In the 12-week study, mean weekly reductions in VMS severity from baseline were significantly greater for Brisdelle™ than for placebo at Week 4 (–0.09 and –0.05, respectively; p = 0.0048) but not at Week 12 (–0.10 and –0.09, respectively; p = 0.2893). In the 24-week study, mean weekly reductions in VMS severity were significantly greater for Brisdelle™ than for placebo at Week 4 (–0.09 and –0.06, respectively; p = 0.0452) and at Week 12 (–0.12 and –0.07, respectively; p = 0.0114).

Brisdelle™ (paroxetine capsules, 7.5 mg/day) was approved by the FDA in June 2013 for the treatment of moderate to severe VMS associated with menopause. In clinical development, Brisdelle™ was referred to as low-dose mesylate salt of paroxetine (LDMP). Prior to the approval of Brisdelle™, hormone therapy was the only FDA-approved treatment for VMS. Many women are unable or unwilling to take hormone therapy to treat their VMS associated with menopause, often leaving symptoms untreated.

During perimenopause, the transition period before a woman reaches menopause, estrogen levels gradually decline and periods may become irregular. Natural menopause is typically confirmed when a woman has missed her menstrual periods for 12 consecutive months. The average age of a woman entering natural menopause is 51 years old. Some women may undergo surgical menopause, which can take place at any age. Surgical menopause occurs when both ovaries are surgically removed (called an oophorectomy), often along with the uterus (called a hysterectomy). Because ovaries are the body's main source of estrogen production, a woman enters menopause when they are removed. The severity of symptoms associated with menopause varies from woman to woman. Hot flashes and night sweats are the most common symptoms of menopause. Because the journey is unique for each woman, it is important for women going through menopause to have a thorough discussion about the transition with their doctors and determine if treatment is appropriate.
