title: Efficacy of flibanserin in women with hypoactive sexual desire disorder: results from the BEGONIA trial.
abstract: BACKGROUND
  Hypoactive Sexual Desire Disorder (HSDD) is characterized by low sexual desire that causes marked distress or interpersonal difficulty.
  
  
  OBJECTIVE
  The aim of this study was to assess the efficacy and safety of the 5-HT1A agonist/5-HT2A antagonist flibanserin in premenopausal women with HSDD.
  
  
  METHODS
  This was a randomized, placebo-controlled trial in which premenopausal women with HSDD (mean age: 36.6 years) were treated with flibanserin 100 mg once daily at bedtime (qhs) (n = 542) or placebo (n = 545) for 24 weeks.
  
  
  METHODS
  Coprimary end points were the change from baseline to study end in Female Sexual Function Index (FSFI) desire domain score and in number of satisfying sexual events (SSE) over 28 days. Secondary end points included the change from baseline in FSFI total score, Female Sexual Distress Scale-Revised (FSDS-R) total score, and FSDS-R Item 13 score.
  
  
  RESULTS
  Compared with placebo, flibanserin led to increases in mean (standard deviation) SSE of 2.5 (4.6) vs. 1.5 (4.5), mean (standard error [SE]) FSFI desire domain score of 1.0 (0.1) vs. 0.7 (0.1), and mean (SE) FSFI total score of 5.3 (0.3) vs. 3.5 (0.3); and decreases in mean (SE) FSDS-R Item 13 score of -1.0 (0.1) vs. -0.7 (0.1) and mean (SE) FSDS-R total score of -9.4 (0.6) vs. -6.1 (0.6); all P ≤ 0.0001. The most frequently reported adverse events in the flibanserin group were somnolence, dizziness, and nausea, with adverse events leading to discontinuation in 9.6% of women receiving flibanserin vs. 3.7% on placebo.
  
  
  CONCLUSIONS
  In premenopausal women with HSDD, flibanserin 100 mg qhs resulted in significant improvements in the number of SSE and sexual desire (FSFI desire domain score) vs. placebo. Flibanserin was associated with significant reductions in distress associated with sexual dysfunction (FSDS-R total score) and distress associated with low sexual desire (FSDS-R Item 13) vs. placebo. There were no significant safety concerns associated with the use of flibanserin for 24 weeks.
