(371) Comparison of Collagenase Clostridium Histolyticum to Surgery for the Management of Peyronie’s Disease: A Randomized Trial – 1 Year Outcomes
Abstract
Since the FDA approval of Collagenase Clostridium Histolyticum (CCH) for the treatment of Peyronie’s Disease (PD), there has been significant debate as to its role and comparable efficacy in relation to surgical therapies. We have previously published results comparing the two therapies at 3-months post-treatment.
To compare various objective and subjective outcome measures at 12-months post-treatment between men undergoing CCH or surgery for PD.
A randomized, controlled trial (NCT04786106) is ongoing. Participants were randomized 1:1 to receive either CCH + traction (RestoreX) + sildenafil or penile surgery (plication and/or incision and grafting) + traction + sildenafil for PD. Objective, standardized (International Index of Erectile Function [IIEF] and Peyronie’s Disease Questionnaire [PDQ]), and non-standardized assessments were obtained at baseline, and post-treatment at 3, 6, 12, 24, 36, 48, and 60 months. Key outcomes included differences in standardized questionnaires, penile curvature, penile length, subsequent interventions, and non-standardized questionnaire responses. Curvature was measured in two planes and summed to provide a composite curvature. Penile length was measured from pubic symphysis to corona. All adjunctive therapies were stopped at 3-months post treatment completion (i.e., traction and sildenafil).
A total of 40 men were randomized, with 38 completing treatment and 12-month data available on 28 men (CCH=12, surgery=16). Mean age at enrollment was…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 40 participants or records.
