BOCA RATON, Fla. and DREIEICH, Germany, Jan. 31, 2013 /PRNewswire/ --Biotest
Pharmaceuticals Corporation (BPC), a wholly owned U.S. subsidiary of Biotest
AG, recently announced the U.S. Food and Drug Administration's (FDA) approval
of BIVIGAM™, its new intravenous immune globulin, for the treatment of
patients with Primary Humoral Immunodeficiency (PI). BIVIGAM is the first new
intravenous immune globulin (IVIG) to be approved by the FDA with a validated
assay for measuring potential thrombogenic activity. Thrombin generation tests
are utilized to detect procoagulant activity. BPC plans to begin shipments of
the product shortly.

To reduce the risk of thromboembolic events that PI patients have experienced
in the past with alternative products, BPC initiated the development and
validation of a TGA test in close cooperation with the FDA. Every lot of BPC's
BIVIGAM will be screened before release to assure the product fulfills the
stringent release criteria pertaining to the threshold levels of Factor XIa.
Increased Factor XIa has been identified as one of the risk factors associated
with thromboembolic events following immune globulin intravenous therapy.

BIVIGAM is a sugar-free, glycine stabilized intravenous immune globulin that
was approved by the FDA on December 19, 2012 and is available in 50 mL (5
gram) and 100 mL (10 gram) tamper-evident vials. The product uses a label with
an integrated hanger and the packaging material is latex free. It is
manufactured in a state-of-the-art US facility and will be available
exclusively for patients and healthcare professionals in the USA. For Full
