Noven Pharmaceuticals Inc. Announces Publication Of Exploratory Analyses From Pooled Phase 3 Results Of The Effects Of Brisdelle® (Paroxetine) Capsules On Weight And Sexual Function During Treatment Of Vasomotor Symptoms Associated With Menopause
MIAMI and NEW YORK, Oct. 14, 2014 /PRNewswire/ -- Noven Pharmaceuticals, Inc., today announced the publication of data on the effects of low-dose mesylate salt of paroxetine (LDMP), marketed as Brisdelle® (paroxetine) capsules, 7.5 mg, in the October 2014 issue of Menopause, the peer-reviewed, scientific journal of The North American Menopause Society (NAMS). The article, "Effects of low-dose paroxetine 7.5 mg on weight and sexual function during treatment of vasomotor symptoms associated with menopause," presents exploratory analyses from pooled results that measured the impact of Brisdelle on weight and sexual function within two, double-blind, randomized, placebo-controlled Phase 3 trials of women with moderate to severe vasomotor symptoms (VMS), commonly referred to as hot flashes.
The article describes the exploratory analyses of pooled data from the two Phase 3 Brisdelle trials. The analyses showed that the frequency of treatment-emergent sexual dysfunction and weight change from baseline were similar between Brisdelle and placebo. As noted in the article, there are limitations to these analyses and it is unknown whether either might appear as an adverse event with longer term therapy.

"Many physicians and patients are aware of reports of sexual dysfunction and changes in body weight in patients taking selective serotonin reuptake inhibitors, and specifically paroxetine, at the higher doses used for depression and other psychiatric disorders," said Joel Lippman, M.D., FACOG, Noven's Executive Vice President Product Development and Chief Medical Officer. "Noven understands this may be an important factor when considering treatment for moderate to severe hot flashes and that these analyses, with their limitations, may help provide physicians with a better understanding of Brisdelle."
Brisdelle was specifically studied and FDA-approved to treat moderate to severe VMS associated with menopause. Brisdelle, at 7.5 mg, is a lower dose of paroxetine than that used to treat a number of psychiatric disorders. Brisdelle has not been studied in or approved for any psychiatric use.
Data collected in the 12 week and 24 week Phase 3 studies and analyzed in the article included changes in body mass index (BMI) and weight, Arizona Sexual Experiences Scale (ASEX), Hot Flash-Related Daily Interference Scale (HFRDIS) sexuality subscore, and adverse events (AEs) related to weight or sexual dysfunction. The article includes results for each of these assessments at week 4, 12 (pooled data) and 24 (24-week study).
Percentage change in median body weight from baseline to Week 4 was 0% in the Brisdelle arm and +0.21% in the placebo arm. The change from baseline in mean body weight at week 12 was +0.17% with Brisdelle and +0.52% with placebo and at week 24 was +0.48% with Brisdelle and +0.09% with placebo. Median change from baseline in BMI and proportion of subjects with weight gain of 7% compared to baseline were also analyzed, and the difference between Brisdelle and placebo trended similarly.
As noted in the article, at the onset of these studies almost 60% of participants reported sexual dysfunction based on the ASEX. The proportion of participants reporting sexual dysfunction in the Brisdelle group compared to placebo at 4 weeks was 56% in both arms, 55% vs 52% at week 12, and 56% vs 57% at week 24, respectively. HFRDIS subscore results were also analyzed and the difference between Brisdelle and placebo trended similarly.
Data regarding weight gain and sexual function (as measured by ASEX) were prospectively collected in both Phase 3 clinical trials. They were not, however, primary endpoints nor pre-specified in the statistical analysis plan and the article presents exploratory analyses of pooled data. The ASEX scale has only been validated in psychiatric patients taking antidepressants. HFRDIS was a pre-specified secondary endpoint in these studies, but the sexuality subscore was evaluated separately in the analyses in this article. The HFRDIS sexuality subscore is not validated for standalone use. The article notes other limitations of the study, including that the study was not specifically designed to evaluate sexual dysfunction in VMS and that the study had a relatively short 24-week duration of treatment and follow-up.
The results of these analyses were also selected for oral presentation at the 2013 Annual Meeting of The North American Menopause Society and are publicly available on clinicaltrials.gov.

Kaunitz, M.D., University of Florida College of Medicine, Jacksonville, FL; Kazem Kazempour, Ph.D. and Hana Mekonnen, M.A., Amarex Clinical Research, Germantown, M.D.; and Sailaja Bhaskar, Ph.D. and Joel Lippman, M.D., Noven Pharmaceuticals, Inc., New York, NY.

Brisdelle (paroxetine) capsules, 7.5 mg, was approved by the FDA in June 2013 for the treatment of moderate to severe VMS associated with menopause, commonly referred to as hot flashes.
Brisdelle, as a treatment for moderate to severe VMS associated with menopause, was studied in one Phase 2 and two, double-blind, randomized, placebo-controlled Phase 3 trials in 1,276 women. 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 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 (paroxetine) capsules is a prescription medicine used to reduce moderate to severe hot flashes associated with menopause.
BRISDELLE is not approved to treat depression or any other psychiatric conditions.

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 are the most common symptom 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.
