About this study
Official title: 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.

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.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 9 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 Oct 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 18 sites in South Korea, Hong Kong, Taiwan, Chile, Singapore. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 8 Mar 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of Participants With Adverse Events (AE) Related to Sexual Function in the Double-blind Treatment Period (time frame: 24 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Oct 2018.
