Sexual Function in Men Receiving Dutasteride for Androgenetic Alopecia

A Prospective Study of Sexual Function in Men Taking Dutasteride for the Treatment of Androgenetic Alopecia

Treatment of male pattern hair loss (MPHL) or androgenetic alopecia (AGA) with 5α-reductase inhibitor (5-ARIs) has been associated with sexual dysfunction including erectile dysfunction and loss of libido. This will be a multicenter, randomized, double-blind, placebo-controlled, parallel-group study to assess the impact of dutasteride treatment on sexual function as well as subject satisfaction with hair growth and quality of life in men with AGA. This study will consist of a Screening Visit, a 4-week Placebo Run-in Phase, a Treatment Phase of 48 weeks, and a subsequent Follow-up Visit after 4 weeks. The treatment phase will include 24 weeks of double-blind, placebo controlled treatment and 24 weeks of open-label treatment with dutasteride. An extended 6-month Follow-up Visit will be conducted for any individuals with a change in erectile function at the end of treatment.

Only those participants available at the specified time points were analyzed (represented by n=X, X in the category titles).	Baseline and up to Week 24
Change From Baseline in the Indicated Clinical Chemistry Parameters in the Open-label Treatment Period: Glucose, Potassium, Sodium and Urea/BUN.	Clinical chemistry parameters included: glucose, potassium, sodium, and urea/BUN at the indicated time points (Week 24 and final value). The Baseline assessment was defined as the latest assessment on or before the open-label treatment start. Change from Baseline is post-Baseline value minus Baseline value. A final value for each period is defined as the latest post-Baseline value available in the period.

Incidence of Premature Discontinuations in the Double-blind Treatment Period	Participants were referred as premature discontinuations if they do not complete the double-blind period. The reasons for premature withdrawal were protocol deviation, lost to follow-up and withdrawal of consent by participants.	Week 24
Incidence of Premature Discontinuations in the Open-label Treatment Period	Participants were referred as premature discontinuations if they do not complete the open-label treatment period.

Number of Participants With a Change in Sexual Function Defined as a Negative Change From Baseline in the International Index of Erectile Function (IIEF) Erectile Function Domain (IIEF-EF) Score of >=4 Units in the Double-blind Treatment Period	The IIEF is a validated 15-item questionnaire with individual items of the questionnaire assigned to five separate domains of sexual function (i.e., erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction). The IIEF was employed to assess treatment-related changes in men with erectile dysfunction. The erectile function domain of the IIEF (IIEF-EF) includes Questions 1 through 5 and Question 15 (maximum score of 30). A clinically meaningful gradient of severity of erectile dysfunction (ED) has been developed, indicating that a score of greater than 25 represents an individual without ED while men scoring <=25 may be classified as having ED. The values are presented for Week 4, Week 12 and Week 24. The Baseline assessment was defined as the latest assessment on or before the DB treatment start. Change from Baseline is post-Baseline value minus Baseline value.	Baseline, Week 4, Week 12 and Week 24

Change From Baseline in Total Score of the IIEF in the Double-blind Treatment Period	The IIEF is a validated 15-item questionnaire with individual items of the questionnaire assigned to five separate domains of sexual function (i.e., erectile function, orgasmic function, sexual desire, intercourse satisfaction, and overall satisfaction). The IIEF was employed to assess treatment-related changes in men with erectile dysfunction. Overall score range is 0-75. The erectile function score range is 0-30, intercourse satisfaction score range is 0-15, orgasmic function score range is 0-10, sexual desire score range is 0-10, overall satisfaction score range is 0-10. A decrease from Baseline indicates a worsening. The change from Baseline values are presented for Week 4, Week 12 and Week 24.

Change From Baseline in Participants Perception of Sexual Function Measured by Responses to the Global Assessment Questions in the Double-blind Treatment Period	The global assessment questions consist of 2 questions, recording how much the participant perceives his sexual life has changed and how he perceives his ability to achieve and maintain erections has changed, compared to how it was before he began receiving treatment in this study. The wording of these questions were based on the Patient Global Impression of Improvement questionnaire, which was validated for use in the assessment of improvement in stress urinary incontinence. The questions were scored on a 7-point scale.The Baseline assessment was defined as the latest assessment on or before the DB treatment start.	Baseline and up to Week 24
