Clinical Trial 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.

Eligibility

Inclusion Criteria:

1. Be a male and be = 18 years of age

2. Be in a stable relationship with a female partner/spouse for at least 3 months before screening and be willing to have vaginal intercourse with that partner/spouse

3. Have symptom(s) of Peyronie's disease for at least 12 months before the first dose of study drug and have evidence of stable disease as determined by the investigator

4. Have penile curvature of at least 30° in the dorsal, lateral, or dorsal/lateral plane at screening. It must be possible to delineate the single plane of maximal curvature for evaluation during the study

5. Be judged to be in good health, based upon the results of a medical history, physical examination, and laboratory profile

6. Voluntarily sign and date an informed consent agreement approved by the Institutional Review Board/Independent Ethics Committee (IRB/IEC). The subject must also sign an authorization form to allow disclosure of his protected health information (PHI). The PHI authorization form and informed consent form may be an integrated form or may be separate forms depending on the institution

7. Be able to read, complete, and understand the various rating instruments in English

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

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

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 -

Intervention

Biological:
• AA4500
2 injections separated by at least 24 hours but not more than 72 hours. At least 24 hours but not more than 72 hours after the 2nd injection of the treatment cycle, the investigator will model the plaque (ie, gradual, gentle stretching of the flaccid penis in the direction opposite to the curvature). Treatment may be repeated after 42 days (± 5 days) for up to 4 treatment cycles.
• Placebo
2 injections separated by at least 24 hours but not more than 72 hours. At least 24 hours but not more than 72 hours after the 2nd injection of the treatment cycle, the investigator will model the plaque (ie, gradual, gentle stretching of the flaccid penis in the direction opposite to the curvature). Treatment may be repeated after 42 days (± 5 days) for up to 4 treatment cycles.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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.	Baseline and Week 52
Primary	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.	Baseline and Week 52
Secondary	A Responder Analysis Based on Subject Overall Global Assessment	Subject overall global assessment of Peyronie's disease score range -3 (much worse) to 3 (much improved). A score of 1 (improved in a small but important way), 2 (moderately improved), or 3 indicated a responder.	Week 52
Secondary	Change From Baseline in the Severity of Peyronie's Disease Symptoms Domain of the PDQ	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.	Baseline and Week 52
Secondary	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.	Baseline and Week 52
Secondary	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.	Baseline and Week 52
Secondary	Change From Baseline in Penile Length	A negative value represents a reduction in measurement from baseline.	Baseline and Week 52
Secondary	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.	Baseline and Week 52
Secondary	A Composite Responder Analysis Based on Change From Baseline in Penile Curvature and in the Peyronie's Disease Bother Score	A composite responder is indicated by; a percent reduction from baseline in penile curvature greater than or equal to the threshold, and; a reduction from baseline in Peyronie's disease bother score greater than or equal to the threshold, or change in the overall sexual activity within the last 3 months to having vaginal intercourse from no vaginal intercourse at screening.
