The study reported that “men treated with collagenase C. histolyticum showed a mean 34% improvement in penile curvature, representing a mean ± SD -17.0 ± 14.8 degree change per subject, compared with a mean 18.2% improvement in placebo treated men, representing a mean -9.3 ± 13.6 degree change per subject (p <0.0001).

The mean change in Peyronie disease symptom bother score was significantly improved in treated men vs men on placebo (-2.8 ± 3.8 vs -1.8 ± 3.5, p = 0.0037). Three serious adverse events (corporeal rupture) were surgically repaired.”  Xiaflex did not affect penile pain and discomfort compare to placebo.
