ABSTRACT
PURPOSE:
Collagenase Clostridium histolyticum is an investigational nonsurgical treatment for Peyronie disease. In this phase 2b, double-blind, randomized, placebo controlled study we determined the safety and efficacy of collagenase C. histolyticum and assessed a patient reported outcome questionnaire. MATERIALS ANDMETHODS:
A total of 147 subjects were randomized into 4 groups to receive collagenase C. histolyticum or placebo (31) with or without penile plaque modeling (11). Per treatment cycle 2 injections of collagenase C. histolyticum (0.58 mg) were given 24 to 72 hours apart. Subjects received up to 3 cycles at 6-week intervals. When designated, investigator modeling was done 24 to 72 hours after the second injection of each cycle. We evaluated penile curvature by goniometer measurement, patient reported outcomes and adverse event profiles.RESULTS:
After collagenase C. histolyticum treatment significant improvements in penile curvature (29.7% vs 11.0%, p=0.001) and patient reported outcome symptom bother scores (p=0.05) were observed compared to placebo. In modeled subjects 32.4% improvement in penile curvature was observed in those on collagenase C. histolyticum compared to 2.5% worsening of curvature in those on placebo (p<0.001). Those treated with collagenase C. histolyticum who underwent modeling also showed improved Peyronie disease symptom bother scores (p=0.004). In subjects without modeling there were minimal differences between the active and placebo cohorts. Most adverse events in the collagenase C. histolyticum group occurred at the injection site and were mild or moderate in severity. No treatment related serious adverse events were reported.CONCLUSIONS:
Collagenase C. histolyticum treatment was well tolerated. We noted significant improvement in penile curvature and patient reported outcome symptom bother scores, suggesting that this may be a safe, nonsurgical alternative for Peyronie disease.
