Official title

Xiaflex® Plus Testosterone Treatment Pilot Study Protocol A Six-month, Pilot Project of Testosterone Treatment in Subjects Who Are Undergoing Xiaflex® Therapy for the Treatment of Peyronie's Disease

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

In this open-label, six-month, pilot study of men with Peyronie's disease there will be one subject group consisting of 20 subjects. All subjects will receive Xiaflex® plus testosterone (T) treatment (Aveed®). Males included in the study must be 18-70 years old; have a history of PD for more than six months; and have at two serum total testosterone level less than 350 ng/dL within 30 days prior to enrollment. The primary objective of this pilot study is to determine whether testosterone therapy offers increased efficacy of Xiaflex® (collagenase clostridium histolyticum) in subjects undergoing treatment for Peyronie's disease. Endpoints will include reduction in degree of curvature and response to the PDQ questionnaire. Secondary objectives will be to assess men for change in plaque size, quality of life parameters, and sexual function. Data collected from this pilot study will be analyzed and compared to historical data regarding treatment for PD using Xiaflex® only. This pilot study will establish preliminary evidence needed to continue more in-depth research regarding Xiaflex® with T therapy and serve as a means to evaluate feasibility of a full-scale study.
