About this study
Official title: A Phase 3, Double-blind, Randomized, Placebo-controlled Study of the Safety and Effectiveness of AA4500 Administered Twice Per Treatment Cycle for up to Four Treatment Cycles (2 x 4) in Men With Peyronie's Disease
This study is a Phase 3, double-blind, randomized, placebo-controlled study of the safety and efficacy of AA4500 0.58 mg in subjects with Peyronie's disease. Approximately 400 (267 AA4500 and 133 placebo) men will be randomized. Subjects will be screened for study eligibility within 21 days before the initial injection of study drug in the first treatment cycle.
Before dosing, subjects will be stratified by degree of penile curvature deformity (ie, 30º to 60º or 61º to 90º) and then randomized into two treatment groups to receive in a 2:1 ratio either AA4500 0.58 mg or placebo.
Read more
In this study, qualified subjects may receive up to four treatment cycles; each cycle will be separated by a period of 42 days (± 5 days). During each treatment cycle, subjects will receive two injections of study drug with at least 24 hours but not more than 72 hours between injections. After the final injection of each treatment cycle, the investigator or qualified designee will model the penile plaque in an attempt to stretch or elongate the plaque. If the subject's penile curvature is reduced to <15 degrees after the first, second, or third cycle of injections or if further treatment is not clinically indicated, subsequent treatment cycles will not be administered.
Following the maximum of four treatment cycles, each subject will be followed for additional safety and efficacy assessments on Days 169 (± 7 days), 232 (± 7 days), 295 (± 7 days), 365 (± 7 days) (nominal weeks 24, 33, 42 and 52). Subjects randomized to placebo may receive open-label AA4500 treatment after completing this study as part of another protocol.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage Change From Baseline in Penile Curvature
A negative value in the percentage change from baseline in penile curvature deformity (angle measured in degrees) indicates less curvature.
Measured: Baseline and Week 52
Change From Baseline in the Peyronie's Disease Bother Domain of the Peyronie's Disease Questionnaire (PDQ)
Peyronie's disease bother score range 0 (no issue or not at all bothered) to 4 (extremely bothered) on 4 questions; total score range 0 to 16. A decrease in the change from baseline total score in the Peyronie's disease bother domain of the PDQ is indicated by a negative number.
Measured: Baseline and Week 52
Secondary outcomes (7)
A Responder Analysis Based on Subject Overall Global Assessment of Peyronie's Disease
A responder was defined as a subject who recorded his Peyronie's disease had either improved in a small but important way, moderately improved, or much improved in overall global assessment question.
Measured: Week 52
Change From Baseline in the Severity of Peyronie's Disease Physical and Psychological Symptoms
Peyronie's disease symptoms (physical and psychological) severity score range 0 (none) to 4 (very severe) on 6 questions; total score range 0 to 24. A decrease in the change from baseline total score in the Peyronie's disease symptoms domain of the PDQ is indicated by a negative number.
Measured: Baseline and Week 52
Change in the Overall Satisfaction Domain of the International Index of Erectile Function (IIEF)
Overall satisfaction domain of the IIEF score range 0 to 5 on 2 questions where higher scores indicate improved function or satisfaction; total score range 0 to 10.
Measured: Baseline and Week 52
Change From Baseline in Penile Plaque Consistency
Penile plaque consistency score range 1 (non-palpable) to 5 (hard). A decrease in the change from baseline score in penile plaque consistency is indicated by a negative number.
Measured: Baseline and Week 52
Change From Baseline in Penile Length
A negative value represents a reduction in measurement from baseline.
Measured: Baseline and Week 52
Change From Baseline in the Penile Pain Domain of the PDQ in Subjects With Baseline Penile Pain Score ≥4
Penile pain scale range 0 (no pain) to 10 (extreme pain) on 3 questions; total score range 0 to 30. A decrease in the change from baseline total score in the penile pain domain of the PDQ is indicated by a negative number. Subjects were required to have a penile pain score of 4 or greater at baseline.
Measured: Baseline and Week 52
Composite Responder Based on Change in Curvature Deformity and Change in Peyronie's Disease Bother Score
A responder was defined as a subject who satisfied the following 2 criteria at that visit: a) percent reduction from baseline in curvature deformity was ≥20% and b) reduction from baseline in PDQ Peyronie's disease bother score was ≥1, or had a change from reporting no sexual activity at screening to reporting sexual activity.
Measured: Week 52

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing AA4500 in people with Peyronie's Disease, run by Endo USA Inc., a Keenova Therapeutics Company at 34 sites in 2 countries.
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 7 inclusion and 32 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 5 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 34 sites in United States, Australia. 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 7 Apr 2015). 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?
Percentage Change From Baseline in Penile Curvature (time frame: Baseline and Week 52). The study lists 2 primary outcomes in all. 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 NCT01221597, which also lists 1 linked publication.
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 5 Oct 2017.
