The primary efficacy endpoint was reduction in Hamilton Anxiety Scale (HAM‐A) total scores from baseline after 8 weeks of treatment. Key secondary outcomes were changes from baseline in HAM‐A total scores for the 2.5 and 10 mg dose, Hospital Anxiety and Depression anxiety subscore, 36‐Item Short‐Form Health Survey, Sheehan Disability Scale, and Clinical Global Impression‐Improvement Scale score, as well as HAM‐A response rate at week 8.</p> </sec> <sec id="hup2371-sec-0004" sec-type="section"> <title>Results</title> <p>Neither vortioxetine dose achieved a statistically significant improvement over placebo on the primary endpoint (least‐squares mean difference ± standard error from placebo: –0.87 ± 0.803 [<italic>p</italic> = 0.279] for 2.5 mg and −0.81 ± 0.791 [<italic>p</italic> = 0.306] for 10 mg vortioxetine) or on any secondary efficacy endpoints.
