What was done

The authors conducted a review synthesizing clinical trial evidence and regulatory data regarding the efficacy and safety of injectable collagenase clostridium histolyticum (Xiaflex) for the nonsurgical management of Peyronie's disease in men with palpable plaque and penile curvature of 30° or greater.

What was found

Clinical trials of collagenase clostridium histolyticum demonstrated mean improvements in penile curvature ranging from 29% to 34%, along with improvements in disease-related bother scores. Adverse events were predominantly mild or moderate in severity, and 79% resolved spontaneously without requiring clinical intervention.

Why it matters

This review contextualizes the clinical trial data that supported FDA approval of the first nonsurgical injectable enzymatic treatment for Peyronie's disease.

Limits

The abstract describes a narrative review without detailing search methodology, study inclusion criteria, or total participant numbers. Long-term durability and safety beyond initial trial periods were not established and require larger extended follow-up studies.
