Baxter International Inc. (NYSE:BAX) and Halozyme Therapeutics, Inc., (NASDAQ:HALO) today announced that the U.S. Food and Drug Administration (FDA) has extended the Prescription Drug User Fee Act (PDUFA) date for its review of the Biologics License Application (BLA) for HYQVIA [Immune Globulin Infusion 10% (Human) with Recombinant Human Hyaluronidase], the company’s investigational subcutaneous treatment for patients with primary immunodeficiency (PI).
The FDA is requiring additional time to review supplemental data that Baxter provided as part of the ongoing BLA process for HyQvia approval. The PDUFA date has been extended by three months, which is the standard extension period. As part of the FDA’s extended review of the HyQvia BLA amendment, Baxter now expects to participate in a Blood Products Advisory Committee (BPAC) meeting, which the agency has scheduled for July 31, 2014.
HyQvia was approved by the European Commission for EU member states in 2013 and is available in several European countries, including Germany, Netherlands, Sweden, Norway, Denmark, Ireland and Italy.
About HyQviaHyQvia is a product consisting of human normal immunoglobulin (IG 10%) and recombinant human hyaluronidase (licensed from Halozyme Therapeutics). The IG provides the therapeutic effect and the recombinant human hyaluronidase facilitates the dispersion and absorption of the IG administered subcutaneously, increasing its bioavailability. The IG is a 10% solution that is prepared from human plasma consisting of at least 98% IgG, which contains a broad spectrum of antibodies. HyQvia is indicated in Europe as replacement therapy in adults (≥18 years) with primary immunodeficiency syndromes and in myeloma or chronic lymphocytic leukaemia (CLL) with severe secondary hypogammaglobulinaemia and recurrent infections. Important Risk Information HyQvia should not be used by patients with a hypersensitivity to human immunoglobulins, especially in very rare cases of IgA deficiency when the patient has antibodies against IgA. HyQvia should not be used by patients with a systemic hypersensitivity to hyaluronidase or recombinant human hyaluronidase. HyQvia should not be used by patients with a hypersensitivity to any of the excipients, including glycine.
