About XIAFLEX XIAFLEX (collagenase clostridium histolyticum, or CCH) is a biologic approved in the U.S., EU, Canada and Australia for the treatment of adult Dupuytren's contracture (DC) patients with a palpable cord and for the treatment of adult men with PD with a palpable plaque and penile curvature deformity of at least 30 degrees at the start of therapy in the U.S. XIAFLEX consists of a combination of two subtypes of collagenase, derived from Clostridium histolyticum. Together, the collagenase sub-types are thought to work synergistically to break the bonds of the triple helix collagen structure. XIAFLEX has been granted Orphan status in the U.S. by the FDA for DC and PD.
