Can healthy volunteers participate?
No
Key exclusion criteria
1. Has a penile curvature of less than 30° or greater than 90° at the screening visit
2. Has any of the following conditions:

* Chordee in the presence or absence of hypospadias
* Thrombosis of the dorsal penile artery and/or vein
* Infiltration by a benign or malignant mass resulting in penile curvature
* Infiltration by an infectious agent, such as lymphogranuloma venereum
* Ventral curvature from any cause
* Presence of an active sexually transmitted disease
* Known active hepatitis B or C
* Known immune deficiency disease or be positive for human immunodeficiency virus (HIV)
3. Has previously undergone surgery for Peyronie's disease
4. Fails to have an erection which in the opinion of the investigator is sufficient to accurately measure the subject's penile deformity after administration of prostaglandin E1 (PGE1) or trimix
5. Has a calcified plaque as evident by appropriate radiographic evaluation, penile x-ray or penile ultrasound that would prevent proper injection of study medication. Non-contiguous stippling of calcium is acceptable for inclusion provided the calcium deposit does not interfere with the injection of AA4500 into the plaque
6. Has an isolated hourglass deformity of the penis
7. Has the plaque causing curvature of the penis located proximal to the base of the penis, so that the injection of the local anesthetic would interfere with the injection of AA4500 into the plaque
8. Has previously received alternative medical therapies for Peyronie's disease administered by the intralesional route (including, but not limited to, steroids, verapamil, and the naturally occurring low molecular weight protein, interferon-a2b) within 3 months before the first dose of study drug or plans to use any of these medical therapies at any time during the study
9. Has received alternative medical therapies for Peyronie's disease administered by the oral (including, but not limited to, vitamin E [> 500 U], potassium aminobenzoate [Potaba], tamoxifen, colchicine, pentoxifylline, over-the-counter erectile dysfunction medications, or steroidal anti-inflammatory drugs) or topical routes (including, but not limited to, verapamil applied as a cream) within 3 months before the first dose of study drug or plans to use any of these medical therapies at any time during the study
10. Has had extracorporeal shock wave therapy (ESWT) for correction of Peyronie's disease within the 6-month period before screening or plans to have ESWT at any time during the study
11. Has used any mechanical type device for correction of Peyronie's disease within the 2-week period before screening or plans to use any these devices at any time during the study
12. Has used a mechanical device to induce a passive erection within the 2-week period before screening or plans to use any of these devices at any time during the study
13. Has significant erectile dysfunction that has failed to respond to oral treatment with phosphodiesterase type 5 (PDE5) inhibitors
14. Has a penile Duplex Doppler ultrasound evaluation at screening that shows compromised penile hemodynamics that in the opinion of the investigator is clinically significant
15. Has uncontrolled hypertension, as determined by the investigator
16. Has a known recent history of stroke, bleeding, or other significant medical condition, which in the investigator's opinion would make the subject unsuitable for enrollment in the study
17. Is unwilling or unable to cooperate with the requirements of the study including completion of all scheduled study visits
18. Has received an investigational drug or treatment within 30 days before the first dose of study drug
19. Has a known systemic allergy to collagenase or any other excipient of AA4500
20. Has a known allergy to any concomitant medication required as per the protocol
21. Has received anticoagulant medication (except for = 165 mg aspirin daily or = 800 mg of over-the-counter NSAIDS daily) during the 7 days before each dose of study drug
22. Has received any collagenase treatments within 30 days of the first dose of study drug
23. Has, at any time, received AA4500 for the treatment of Peyronie's disease -

Summary
Brief summary
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 300 (200 AA4500 and 100 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 (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.

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 the investigator determines further treatment is not clinically indicated (eg, adverse events; allergic reaction), 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.
