XIAFLEX

COLLAGENASE CLOSTRIDIUM HISTOLYTICUM
Infectious Disease Approved 2010-02-02

XIAFLEX is a combination of bacterial collagenases indicated for the treatment of adult patients with Dupuytren’s contracture who have a palpable cord. It is also approved for the treatment of adult men with Peyronie’s disease who present with a palpable plaque and a curvature deformity of at least 30 degrees. The drug serves as a targeted enzymatic intervention to address physical deformities caused by collagen accumulation in the hand or penis.

How XIAFLEX Works

XIAFLEX contains collagenases that hydrolyze collagen in its native triple helical conformation, resulting in the lysis of collagen deposits. When injected directly into a Dupuytren’s cord or a Peyronie’s plaque, the enzymes enzymatically disrupt the Type I and Type III collagen that primarily compose these structures. This disruption breaks down the physical cord or plaque to reduce contractures and penile curvature. The treatment specifically targets collagen deposits while generally sparing the structural integrity of arteries, nerves, and large veins.

XIAFLEX Boxed Warning

CORPORAL RUPTURE (PENILE FRACTURE) OR OTHER SERIOUS PENILE INJURY IN THE TREATMENT OF PEYRONIE’S DISEASE Corporal rupture (penile fracture) was reported as an adverse reaction in 5 of 1044 (0.5%) XIAFLEX-treated patients in clinical studies. In other XIAFLEX-treated patients (9 of 1044; 0.9%), a combination of penile ecchymoses or hematoma, sudden penile detumescence, and/or a penile “popping” sound or sensation was reported, and in these cases, a diagnosis of corporal rupture cannot be excluded...
