Xiaflex® Plus Testosterone Treatment Pilot Study Protocol

medication indicated for the treatment of adult men with Peyronie's disease with a palpable plaque and curvature deformity of at least 30 degrees at the start of therapy. Xiaflex belongs to a family of enzymes called collagenases. Collagenases are proteinases that hydrolyze collagen in its native triple helical conformation under physiological conditions, resulting in lysis of collagen deposits. The signs and symptoms of Peyronie's disease are caused by a collagen plaque. Injection of XIAFLEX into a Peyronie's plaque, which is comprised mostly of collagen, may result in enzymatic disruption of the plaque. Following this disruption of the plaque, penile curvature deformity and patient bother caused by Peyronie's disease are reduced
