Sobi files for EU approval of Xiapex for Peyronies disease

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[i]. After
approximately 12 months of disease, the disease is reported to often develop
into a more chronic, stable phase(i). The incidence of PD is estimated between
3 and 9 percent(ii); however the disease is thought to be underdiagnosed and
undertreated(i).

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.
