Ottawa, ON – October 10, 2018
Global biotherapeutics leader CSL Behring announced that Hizentra® (Subcutaneous Immunoglobulin [Human] 20% Liquid) has been approved for the treatment of chronic inflammatory demyelinating polyneuropathy (CIDP) as maintenance therapy to prevent relapse of neuromuscular disability and impairment in Canada. The approval was based on data from the Phase III PATH (Polyneuropathy And Treatment with Hizentra®) study, which is the largest controlled clinical trial in CIDP patients to date. CIDP is a rare autoimmune disorder that affects the peripheral nerves and may cause permanent nerve damage. The recommended subcutaneous dose range for the treatment of CIDP is 0.2 to 0.4 g/kg (1 mL to 2 mL/kg) body weight per week.
In CIDP, the myelin sheath, or the protective covering of the nerves, is damaged, which may result in numbness or tingling, muscle weakness, fatigue, and other symptoms. The effects of CIDP can worsen over time, leading to significant activity limitations and a decreased quality of life. Approximately 30 percent of CIDP patients will progress to wheelchair dependence if not treated.  It is estimated that approximately 8.9 people per 100,000 are affected by the disease with a yearly incidence of 1.6/100,000.
“The approval of Hizentra® in Canada marks an important milestone for patients struggling with the disabling neurological effects of CIDP,” said Dr. Vera Bril, investigator in the PATH trial and Professor of Medicine (Neurology) at the University of Toronto.
“Continued research and innovation is critical for people living with debilitating neuromuscular diseases like CIDP, so we must encourage companies to keep investing in Canadian research” said Donna Hartlen, executive director of the GBS|CIDP Foundation Canada. “The approval of Hizentra for CIDP now offers patients an option that will allow them to administer their treatment at home.”
Hizentra® is currently approved in 51 countries for the treatment of certain immune deficiencies.
