Baxter Receives Marketing Authorization from the European Commission for KIOVIG to Treat Immunodeficiencies

Baxter Healthcare S.A. announced today that the European Medicines Agency (EMEA) has issued a Marketing Authorization for KIOVIG™ [Immune Globulin Intravenous (Human)], Baxter´s ready-to-use liquid 10% Intravenous Immunoglobulin (IVIG).

KIOVIG is indicated in the European Union for replacement therapy in Primary Immunodeficiency Disorders (PID), Myeloma or Chronic Lymphocytic Leukemia (CLL) with severe secondary hypogammaglobulinemia and recurrent infections, children with congenital AIDS and recurrent infections, Kawasaki Syndrome, allogeneic bone marrow transplantation, Guillain Barré Syndrome, and Idiopathic Thrombocytopenic Purpura (ITP) in children or adults at high risk of bleeding or prior to surgery to correct the platelet count.

The product offers fast and effective treatment and enhanced convenience. Its efficacy and tolerability have been demonstrated in multi-center clinical trials in Europe and the United States. The manufacturing process also incorporates three dedicated viral reduction steps. The ready-to-use preparation eliminates the need for reconstitution and its 10% concentration allows for reduced infusion volume when compared to 5% concentrations. In addition, it is the first and only 10% IVIG solution with the following combination of features: no added sugars, no added sodium, no added preservatives, latex-free packaging and an option to store the product at room temperature for up to nine months.

“The launch of KIOVIG is the latest step in Baxter's efforts toward advancing the science of IVIG," said Jim Utts, president of Baxter Europe. “We are excited to offer this new liquid IVIG to help meet the needs of physicians, healthcare professionals and patients.”

KIOVIG received a unanimous positive opinion recommendation from the Committee for Medicinal Products for Human Use (CHMP) in November of 2005, which served as the basis for approval by the European Commission. Approval from the European Commission will allow Baxter to market the therapy in all 25 European Union member states, as well as Norway and Iceland.

Baxter received regulatory approval from the U.S. FDA in May of 2005, and the therapy was launched in the United States in September. A submission for approval was also made to Health Canada in December of 2004.

About KIOVIG

The product is a ready-to-use, sterile 10% preparation of highly purified and concentrated immunoglobulin G (IgG) antibodies. It is processed from human plasma and contains a broad spectrum of IgG antibodies against infectious agents. Assuring state of the art quality standards for the manufacture begins with the donor selection process and continues throughout plasma collection, which only occurs at licensed plasma collection facilities. To further support the margin of safety, three validated, independent and effective virus inactivation/removal steps have been integrated into processing and formulation (solvent/detergent (S/D) treatment, nanometer filtration and low pH incubation at elevated temperature).

About Primary Immunodeficiency Disorders

Primary Immunodeficiency Disorders (PID) encompass more than 100 diseases caused by an immune system that does not function correctly. In Europe, PID affects approximately one in 500 people, and experts estimate that another one in 500 is yet undiagnosed. For the EU, this is equivalent to 1.5 million affected individuals, 50 percent of whom are undiagnosed. IVIG therapy can restore IgG levels to normal or near normal, helping the immune system function properly and prevent infections or combat them when they occur.

About Autoimmune Disorders

Autoimmune disorders encompass a broad spectrum of human illnesses. Autoimmune diseases are defined as diseases in which the progression from benign autoimmunity to pathogenic autoimmunity occurs. In such cases the immune system mistakenly identifies a person's own tissues (e.g. nerve cells) as foreign and attacks and destroys them. IVIG therapy can help neutralize auto-antibodies and also help modulate B-cell response, which may lead to stabilization of the patient.

Important Safety Information for the United States

KIOVIG is marketed as GAMMAGARD LIQUID™ [Immune Globulin Intravenous (Human)], in the United States.

GAMMAGARD LIQUID is contraindicated in patients with known anaphylactic or severe hypersensitivity responses to Immune Globulin (Human). Patients with severe selective IgA deficiency (IgA <>

IVIG products have been associated with renal dysfunction, acute renal failure, osmotic nephrosis, and death. While these reports of renal dysfunction and acute renal failure have been associated with the use of many of the licensed IVIG products, those containing sucrose as a stabilizer accounted for a disproportionate share of the total number. GAMMAGARD LIQUID does not contain sucrose.

GAMMAGARD LIQUID is made from human plasma. Products made from human plasma may carry a risk of transmitting infectious agents, such as viruses, that can cause disease.

The potential risks and benefits of IVIG should be weighed against those of alternative therapies for all patients for whom IVIG administration is being considered.
