Sobi files for EU approval of Xiapex for Peyronies disease

STOCKHOLM and CHESTERBROOK, Pa., June 25, 2014 /PRNewswire/ -- Swedish Orphan Biovitrum AB (publ) (Sobi) and Auxilium Pharmaceuticals, Inc. today announced that Sobi has filed for an extension of the label for Xiapex® (collagenase clostridium histolyticum) with the European Medicines Agency (EMA) to include the indication of Peyronie's disease.

The filing is based on positive safety and efficacy outcome data from two double-blind placebo-controlled studies, IMPRESS I and II (The Investigation for Maximal Peyronie's Reduction Efficacy and Safety Studies) which evaluated Xiapex for the treatment of Peyronie's disease. The EMA filing follows the approval from the United States Food and Drug Administration (FDA) in December 2013 of XIAFLEX® (collagenase clostridium histolyticum) 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 is the tradename for Xiapex® used in the United States.

"We believe that Xiapex, if approved for this new indication, has the clinical profile to make a major contribution to the field in Peyronie's disease," says Anders Edvell, MD, PhD, Vice President Sobi Partner Products.

Xiapex is approved in Europe for the treatment of Dupuytren's contracture in adult patients with a palpable cord. Sobi is Marketing Authorisation Holder (MAH) for Xiapex in 28 EU member countries as well as Norway and Iceland. Sobi holds the exclusive rights to commercialise Xiapex for Dupuytren's contracture and Peyronie's disease indications in these countries subject to applicable regulatory approvals.

About Peyronie's disease
Peyronie's Disease (PD) is a condition that involves the development of collagen plaque, or scar tissue, on the shaft of the penis. The scar tissue, known as a Peyronie's plaque, may harden and reduce flexibility, which may cause bending or arching of the penis during erection. PD can result in varying degrees of penile curvature deformity and disease "bother" (encompassing concern about erection appearance, erection pain and the impact of PD on intercourse and on frequency of intercourse). PD is a disease with an initial inflammatory component. This inflammatory phase is poorly understood with a somewhat variable disease course and spontaneous resolution occurring in less than 13 percent of cases^[1]. After approximately 12 months of disease, the disease is reported to often develop into a more chronic, stable phaseⁱ. The incidence of PD is estimated between 3 and 9 percentⁱⁱ; however the disease is thought to be underdiagnosed and undertreatedⁱ. 

About Xiapex
Xiapex (collagenase clostridium histolyticum), is a pharmacological treatment for Dupuytren's contracture and may be an alternative to invasive and often complicated surgery for patients. Xiapex is a combination of two purified clostridial collagenases for injection that enzymatically disrupts the contracting cord and reduces the contraction. It is administered by local injection directly into the Dupuytren's cord – a procedure which can be carried out in an outpatient setting. Twenty-four hours after the injection, a finger extension procedure can be carried out as necessary to break the cord and allow extension of the finger.
