Brief summary
The purpose of this study is to compare key clinical outcomes of collagenase clostridium histolyticum injections versus surgery for the management of Peyronie's Disease.
Detailed description
After eligible patients have been informed about the study protocol and risks and consent have been given, men will be randomly assigned into either the collagenase clostridium histolyticum + penile traction therapy (CCH + PTT) group or to the surgery + penile traction therapy (surgery + PTT) group. Those in the CCH + PTT group will receive the full 4 series of 8 Xiaflex injections with 1-3 days between each set of 2 injections and 6 weeks prior to the next series. Patients would then use the RestoreX traction device throughout the series to 3 months post-treatment. Those that were assigned the surgery + PTT treatment protocol would undergo surgery using either penile plication or incision and grafting, depending on the degree of curvature and erectile function. Traction using RestoreX will also be prescribed to these men 2-4 weeks post-operatively until 3 months post-treatment. Key clinical outcomes of both treatment protocols will be compared.
Interventions
Men in this cohort would receive the full series of 8 Xiaflex injections: 2 injections separated by 1-3 days, repeated 3 additional times with 6 week breaks between treatments.
Men in this cohort would undergo surgery using either penile plication or incision and grafting. The specific surgery would be selected based on commonly used criteria: plication for curvatures \<70 degrees; I\&G used for ≥70 degrees or severe hourglass / hinge deformities. However, the specific surgery (plication vs I\&G) will ultimately be decided based on the primary investigator's clinical judgment.

RestoreX is a Class I PTT device developed by PathRight Medical, is registered with the FDA, and has randomized controlled data demonstrating efficacy when used for the treatment of PD.
