KING OF PRUSSIA, Pa., Sept. 3, 2013 /PRNewswire/ -- CSL Behring today
announced that the U.S. Food and Drug Administration (FDA) has approved a 10 g
(50 mL) vial size for Hizentra®,  Immune Globulin Subcutaneous (Human).
Hizentra, the first and only 20 percent subcutaneous immunoglobulin therapy,
keeps serum immunoglobulin G (IgG) levels consistent week to week to help
protect people with primary immunodeficiency (PI) against infections. The new
vial size, 10 g (50 mL), will be available in the U.S. in October.

PI is a group of rare and serious diseases of the immune system. Approximately
250,000 individuals (or one person per 1,200) in the U.S. are diagnosed with
PI. The 10 g vial size of Hizentra will reduce the number of vials that
patients must use when higher doses are required, thus increasing
administration efficiency and reducing complexity of care.

"CSL Behring remains dedicated to providing every patient with options that
will enhance his or her treatment experience," said Lynne Powell, Senior Vice
President, North America Commercial Operations, CSL Behring. "The availability
of Hizentra in a 10 g vial will reduce vial preparation for infusion,
therefore saving time for both patients and their caregivers."

In addition to the new 10 g (50 mL) vial, Hizentra is also available in 1 g (5
mL), 2 g (10 mL) and 4 g (20 mL) vials.

Important Safety Information
Immune Globulin Subcutaneous (Human), Hizentra^®, treats various forms of
primary immunodeficiency (PI) in patients age 2 and over.

Hizentra should not be used if you have had serious negative reactions to
immune globulin (Ig) preparations or a deficiency of an Ig known as IgA.
Because Hizentra contains the amino acid proline as stabilizer, patients with
hyperprolinemia (too much proline in the blood) should not take Hizentra.

Infuse Hizentra under your skin only; do not inject into a blood vessel.

Allergic reactions can occur with Hizentra. If your doctor suspects you are
having a bad allergic reaction or are going into shock, treatment will be
discontinued. Immediately tell your doctor or go to the emergency room if you
have signs of such a reaction, including hives, trouble breathing, wheezing,
dizziness, or fainting.

Tell your doctor about any side effects that concern you. Your doctor will
monitor for potentially serious reactions that have been seen with Ig
treatment, including thrombotic events (blood clotting); aseptic meningitis
syndrome (brain swelling); osmotic nephropathy (a kidney condition); hemolysis
(a blood problem) and transfusion-related acute lung injury.

The most common drug-related adverse reactions in the clinical trial for
Hizentra were injection-site reactions (swelling, pain, redness, heat or
itching); headache; back pain; diarrhea; tiredness; cough; rash; itching;
nausea and vomiting.

Hizentra is made from components of human blood. The risk of transmission of
infectious agents, including viruses and, theoretically, the Creutzfeldt-Jakob
disease (CJD) agent, cannot be completely eliminated.

Vaccines (such as measles, mumps and rubella) might not work as well if you
are using Hizentra. Before receiving a vaccination, tell the healthcare
professional that you are being treated with Hizentra. Also tell your doctor
if you are pregnant or nursing, or if you plan to become pregnant.
