简要总结
The purpose of this study is to evaluate the efficacy and safety of vortioxetine, once daily (QD), in adults with Generalized Anxiety Disorders.
详细描述
The drug that was tested in this study is called Vortioxetine. Vortioxetine is being tested to treat anxiety in adults who have general anxiety disorder (GAD). This study looked at GAD relief in people who took vortioxetine.
The study enrolled 301 patients. Participants were randomly assigned (by chance, like flipping a coin) to one of the two treatment groups-which remained undisclosed to the patient and study doctor during the study (unless there was an urgent medical need):
- Vortioxetine 5 mg
- Placebo (dummy inactive pill) - this was a capsule that looked like the study drug but had no active ingredient.
All participants were asked to take one capsule at the same time each day throughout the study.
This multi-center trial was conducted in Europe. The overall time to participate in this study was up to 13 weeks. Participants made 7 visits to the clinic, and were contacted by telephone 4 weeks after the last dose of study drug for a follow-up assessment.

结局指标
主要结局
Change From Baseline in the Hamilton Anxiety Scale (HAM-A) Total Score at Week 8
时间窗: Baseline to Week 8
The HAM-A is an anxiety rating scale consisting of 14 items that assess anxious mood, tension, fear, insomnia, intellectual (cognitive) symptoms, depressed mood, behavior at interview, somatic (sensory), cardiovascular, respiratory, gastrointestinal, genitourinary, autonomic and somatic (muscular) symptoms. Each symptom is rated from 0 (absent) to 4 (maximum severity). Total scores range from 0 to 56 where \<17 indicates mild severity, 18-24 mild to moderate severity and 25-30 moderate to severe. Total scores above 30 are rare, but indicate very severe anxiety. Least Squares (LS) means were from a mixed model for repeated measurements (MMRM) with Baseline-by-week, center, week and week-by-treatment as factors in the analysis.
