STOCKHOLM and BRIDGEWATER, N.J., Feb. 19, 2013 /PRNewswire/ --Sobi (STO:
SOBI) and Savient Pharmaceuticals, Inc. (NASDAQ: SVNT) announced today that
they have entered into an agreement for the co-promotion of Kineret^®
(anakinra) in the U.S. 

Kineret, a recombinant IL-1 receptor antagonist, is a treatment for rheumatoid
arthritis (RA) and indicated for the reduction in signs and symptoms and
slowing the progression of structural damage in moderately to severely active
RA in patients 18 years of age or older who have failed one or more disease
modifying antirheumatic drugs (DMARDs). Kineret is also indicated in the U.S.
for the treatment of children and adults with the severe form of
Cryopyrin-Associated Periodic Syndromes (CAPS) called Neonatal-Onset
Multisystem Inflammatory Disease (NOMID).

"Savient's organization will enhance our support for Kineret in the United
States," said Alan Raffensperger, Chief Operating Officer of Sobi. "The
collaboration will expand our reach to U.S. physicians who treat patients
suffering from rheumatoid arthritis and augment our own ability to directly
support the pediatric community. Kineret is an important treatment for these
patient groups."

Savientis a specialty biopharmaceutical company that has developed and
commercialized KRYSTEXXA^®(pegloticase) for the treatment of refractory
chronic gout in the U.S. Savient's specialized sales force has strong,
established relationships with rheumatologists in the U.S., making Savient an
excellent partner for Sobi.

"We are pleased to announce the collaboration with Sobi," said Lou Ferrari,
President and Chief Executive Officer of Savient. "Kineret complements the
strategic direction and focus of Savient, as we continue to build upon our
existing relationships with rheumatologists and patients while marketing our
own product, KRYSTEXXA. We look forward to working with Sobi to make Kineret
more widely available to patients with rheumatoid arthritis."

Under the terms of the agreement, Sobi has granted to Savient the exclusive
right to co-promote the sale of Kineret with Sobi in the U.S. Savient will
market and promote Kineret beginning April 1, 2013. Sobi will remain
responsible for all Kineret commercial drug manufacturing, supply, safety, and
regulatory activities.

About Rheumatoid Arthritis
Rheumatoid arthritis is a common systemic disease that affects connective
tissue. Arthritis is the dominant clinical manifestation, involving many
joints, especially those of the hands and feet. The course is variable, but
often chronic and progressive, leading to deformity and disability.Patients
with rheumatoid arthritis produce excess amounts of inflammatory cytokines,
among them Interleukin-1. This leads to harmful effects such as swelling and
tissue damage.

About CAPS and NOMID
Cryopyrin associated periodic syndromes (CAPS) are a group of rare inherited
autoinflammatory diseases caused by autosomal dominant mutations in a gene
called NLRP3. CAPS is characterized by uncontrolled overproduction of
IL-1beta. IL-1 induces a number of inflammatory responses such as fever, pain
sensitization, bone and cartilage destruction and acute plasma protein
responses. In the most severe form NOMID, also called chronic infantile
neurologic cutaneous and arthritis syndrome (CINCA) in Europe, it is
associated with increased mortality and fever, rash, chronic aseptic
meningitis, sensorineural hearing loss, craniofacial abnormalities, and bone
lesions. When of intermediate severity, the disease is typically associated
with episodic, intense and enduring flares and morbidity, including
progressive hearing loss and kidney failure secondary to amyloidosis (a
condition where amyloid proteins are deposited in organs and/or tissues). The
mildest form presents with cold-induced episodes of fever, rash and malaise.
The incidence of CAPS is estimated to be 1:1,000,000 worldwide.

About Kineret (anakinra)
Kineret^® is a recombinant protein drug approved for the treatment of children
and adults with NOMID, and the reduction in signs and symptoms and slowing the
progression of structural damage in moderately to severely active rheumatoid
arthritis (RA), in patients 18 years of age or older who have failed one or
more disease modifying antirheumatic drugs (DMARDs). Kineret blocks the
biological activity of IL-1 by binding to the interleukin-1 type 1 receptor,
expressed in a wide variety of tissues and organs. IL-1 is a key mediator of
inflammation and driver of autoinflammatory diseases in both adults and
children. For more information on Kineret see the Prescribing Information.

    chills, or have any open sores on your body.
  olow white blood cell count (neutropenia). Kineret may cause you to have a
    lower number of certain white cells (neutrophils). Neutrophils are
    important in fighting infections. You should have blood tests before
    starting treatment with Kineret, then monthly for 3 months. After the
    first 3 months you should have your blood tested every 3 months for up to
    1 year.

    outside of the injection site area; dizziness or fainting; fast heartbeat
    or pounding in your chest (tachycardia); or sweating.

The most common side effects of Kineret include:

  oinjection site skin reactions, including redness, swelling, bruising,
    itching, and stinging. Most injection site reactions are mild, occur early
    during treatment, and last about 2-4 weeks. Injection site reactions have
    been observed less frequently in people with NOMID.
  onausea and vomiting
  ojoint pain
  ofeeling like you have the flu
  osore throat or runny nose
