FDA Accepts BLA for CSL Behring’s Hizentra
FDA has accepted a CSL Behring BLA for Hizentra [immune globulin subcutaneous (human) 20% liquid] for treating chronic inflammatory demyelinating polyneuropathy (CIDP) as maintenance therapy to prevent relapse of neuromuscular disability and impairment. CIDP is a rare immune-mediated disorder involving peripheral nerves and the effects can worsen over time. The submission is based on data from the PATH (Polyneuropathy And Treatment with Hizentra) clinical trial that was designed to demonstrate the efficacy, safety and tolerability of two different doses. A long-term open label extension study is ongoing and is expected to be completed later this year. Currently, Hizentra is approved for treating patients with primary immunodeficiency.
