About this study
Official title: A Placebo-Controlled, Double-Blind, Randomized, Parallel Study Of The Efficacy And Safety Of Dapoxetine HCl In The Treatment Of Rapid Ejaculation
The primary purpose of the study is to demonstrate that dapoxetine can prolong intravaginal ejaculatory latency time (IELT) compared with placebo in men with premature ejaculation (PE).
Read the detailed description
One form of male sexual dysfunction is premature ejaculation (PE), which is also referred to as rapid ejaculation (RE). An objective measurement of PE in clinical studies is the intravaginal ejaculatory latency time (IELT). This is a randomized, double-blind study in men with PE. The study consists of 2 phases: pre-randomization phase (a screening visit and a 2-week baseline period); 12-week double-blind treatment phase during which patients will receive dapoxetine at one of two dosages, or placebo, for use on an "as-needed" basis. The total duration of the study is approximately 14 weeks. Patients and their partners are expected to attempt sexual intercourse at least 4 times during the baseline period and at least 6 times each month during the treatment phase. Assessments of effectiveness include the average Intravaginal Ejaculatory Latency time (IELT), as measured by stopwatch, during sexual intercourse for the treatment period (12 weeks); control over ejaculation, satisfaction with sexual intercourse, and severity of symptoms, based on questions asked at monthly intervals through the treatment phase. Safety assessments include the incidence, severity, and type of adverse events throughout treatment (12 weeks), vital sign measurements (pulse and blood pressure) and laboratory tests (hematology, chemistry, urinalysis) at monthly intervals. The study hypothesis is that treatment for 12 weeks with dapoxetine prolongs intravaginal ejaculatory latency time, compared with placebo, in men with PE. Oral tablets of dapoxetine (30 milligrams[mg] or 60mg) taken as needed during 12 weeks of treatment. No more than one dose within a 24-hour period.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Dapoxetine in people with Ejaculation, run by Alza Corporation, DE, USA.
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 6 inclusion and 5 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 19 May 2011. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Average intravaginal ejaculatory latency time (IELT), as measured by stopwatch during sexual intercourse, between last 2 visits during the treatment period. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00211107, which also lists 2 linked publications.
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 19 May 2011.
