Clinical Trial Summary

The purpose of this study is to evaluate the effect of vortioxetine (10 and 20 mg, once daily) versus paroxetine (20 mg, once daily) on sexual functioning in healthy participants after 5 weeks of double-blind treatment.

Description:

The drug being tested in this study is called vortioxetine. This study will look at the effect of treatment on sexual functioning in healthy participants.

The study will enroll approximately 352 participants. Participants will be randomly assigned (by chance, like flipping a coin) to one of the four treatment groups—which will remain undisclosed to the patient and study doctor during the study (unless there is an urgent medical need):

• Vortioxetine 10 mg

• Vortioxetine 20 mg

• Paroxetine 20 mg

• Placebo (dummy inactive pill) - this is a capsule that looks like the study drug but has no active ingredient

All participants will be asked to take one tablet/capsule, daily, orally for up to 5 weeks.

This multicenter trial will be conducted in United States. The overall time to participate in this study is approximately 7 weeks. Participants will be contacted by telephone 2 weeks after last dose of study drug for a follow-up assessment.

Type	Measure	Description	Time frame	Safety issue
Primary	Change From Baseline in the Changes in Sexual Functioning Questionnaire (CSFQ-14) Total Score Difference for Vortioxetine Versus Paroxetine at Week 5 in Full Analysis Set (FAS)	The CSFQ-14 is a structured, self-reported questionnaire designed to measure illness- and medication-related changes in sexual functioning consisting of 14 items that measure sexual functioning as a total score (14 items) and on the subscales of pleasure (1 item), desire/frequency (2 items), desire/interest (3 items), arousal (3 items), orgasm (3 items) and 2 additional items are included in the total score, but do not map to a specific phase of the sexual response cycle, rated on a 5-point scale from 1 to 5 with a total score range from 14 to 70. Higher scores reflect higher sexual functioning. A negative change from baseline indicates that symptoms have worsened.	Baseline and Week 5
Primary	Change From Baseline in the CSFQ-14 Total Score Difference for Vortioxetine Versus Paroxetine at Week 5 in Modified Full Analysis Set 1 (mFAS1)	The CSFQ-14 is a structured, self-reported questionnaire designed to measure illness- and medication-related changes in sexual functioning consisting of 14 items that measure sexual functioning as a total score (14 items) and on the subscales of pleasure (1 item), desire/frequency (2 items), desire/interest (3 items), arousal (3 items), orgasm (3 items) and 2 additional items are included in the total score, but do not map to a specific phase of the sexual response cycle, rated on a 5-point scale from 1 to 5 with a total score range from 14 to 70.
