Evaluating collagenase treatment for Peyronie's disease after PRP therapy

Safety and Efficacy of Collagenase Clostridium Histolyticum After Prior Intralesional Platelet Rich Plasma for Peyronie's Disease

Phase 4 Interventional University of Miami · NCT05777031

This study is testing if collagenase injections can help men with Peyronie's disease who have already tried platelet-rich plasma treatment to see if it improves their condition.

What this trial studies

This study investigates the safety and efficacy of collagenase clostridium histolyticum (CCH) injections in patients with Peyronie's disease who have previously received intralesional platelet-rich plasma (PRP) treatment. Participants will be assessed for the presence of penile plaques and curvature deformities, with a focus on understanding the side effects and overall effectiveness of CCH as a secondary treatment. The study aims to provide insights into the potential benefits of combining these two treatment modalities for improved patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are men diagnosed with Peyronie's disease who have stable disease and have undergone prior PRP treatment within the last 18 months.

Not a fit: Patients with severe erectile dysfunction, previous penile surgeries, or specific plaque characteristics may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could offer a new effective option for patients suffering from Peyronie's disease, potentially improving their penile curvature and overall sexual function.

How similar studies have performed: While the combination of CCH and PRP is a novel approach, previous studies have shown success with CCH alone in treating Peyronie's disease.

Eligibility criteria

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.
