Clinical Trial Summary

The purpose of this study is to learn about the safety and side effects of intralesional collagenase clostridium histolyticum (CCH) injected into the Peyronies Disease (PD) plaque after receiving prior treatment with intralesional Platelet Rich Plasma (PRP) injections.

Eligibility

Inclusion Criteria:

1. Be able to provide written informed consent

2. Have a diagnosis of PD with evidence of stable disease as determined by the investigator

3. Patient must have palpable penile plaque

4. Penile curvature deformity of >30° to <90°

5. Agree to comply with all study related tests/procedures.

6. Prior intralesional platelet rich plasma treatment within the past 18 months and desire secondary treatment of penile curvature

Exclusion Criteria:

1. Previous penile surgery of any kind (except circumcision and condyloma removal), such as penile lengthening, penile cancer surgery, penile plication, grafting, penile prosthesis.

2. Previous intralesional injection therapy with CCH for PD within six months. Patients with failed therapy greater than six months ago may be included.

3. Previous history of priapism or penile fracture

4. PD characterized by a ventral plaque

5. Severe erectile dysfunction as characterized with an IIEF score = 12

6. Hour-glass deformity

7. Unwilling to participate

8. Medically unfit for sexual intercourse as deemed by the principal investigator

9. Patients scheduled to undergo an elective medical procedure during the investigation timeframe that will interfere with autologous PRP injection therapy.

10. Have a serious comorbid illness/condition/behavior that, in the opinion of the investigator, may compromise the safety or compliance of the subject or preclude successful completion of the study.

Intervention

Drug:

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Treatment Related Adverse Events	To determine number of treatment related adverse events. Safety will be evaluated via the incidence of adverse events as assessed by treating physician	up to 6 months (post-intervention)
Primary	Percent change of penile curvature in degrees.	Treatment efficacy of CCH will be assessed via the percentage of participants achieving degree change in penile curvature from baseline. Degree of curvature will be measured using a goniometer with the aid of injection of vasoactive substance into the penis.	Baseline up to 6 months
Secondary	Change in Peyronie's Disease Questionnaire (PDQ) sub-domain scores (Psychological and Physical Symptoms, Symptom Bother).	Treatment efficacy will be assessed via the change of participants achieving any decrease in Peyronie's disease Questionnaire (PDQ) sub-domain scoring from baseline. The sub-domains that will be assessed in primary outcome is Psychological and Physical Symptoms and Symptom Bother. PDQ is a validated 15-item questionnaire that assess Psychological and Physical Symptoms, Symptom Bother, and Penile Pain subdomains. The Psychological and Physical Symptoms subdomain is measured from 0 to 24 (most severe symptoms). Symptom Bother subdomain is measured from 0 to 30 (most severe pain).	Baseline, 6 months.
Secondary	Changes in International Index of Erectile Function - Erectile Function (IIEF-EF) scores	IIEF-EF is a 5-item subdomain self-evaluation questionnaire of erectile function. Each item is scored from 0-5 with the total score ranging from 0-25 with the higher score indicating better erectile function.	Baseline, 6 months
