Baxalta Receives Positive CHMP Opinion for Use of ONCASPAR (pegaspargase) in European Union as a Component of Combination Therapy in Acute Lymphoblastic Leukaemia

Baxalta Incorporated BXLT, a global biopharmaceutical leader dedicated to delivering transformative therapies to patients with orphan diseases and underserved conditions, today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion recommending marketing authorization for use of ONCASPAR as a component of antineoplastic combination therapy in acute lymphoblastic leukaemia (ALL) in paediatric patients from birth to 18 years, and adult patients. The CHMP's positive opinion will now be referred to the European Commission (EC), which grants marketing authorization for medicines in the European Union. Pending EC approval, Baxalta will be authorized to market ONCASPAR in the 28 member countries of the European Union (EU), as well as Iceland, Liechtenstein and Norway. Pending EC approval, ONCASPAR will provide an important treatment option for more European patients with this rapidly progressing cancer of the white blood cells responsible for more than 80 percent of childhood leukaemia cases2 - the most common type of childhood cancer. "We are pleased to receive a positive CHMP opinion for ONCASPAR as part of a multi-agent chemotherapy regimen in paediatric and adult populations; this is a significant milestone in increasing patient access to this important biologic treatment for patients impacted by ALL," said John Orloff, M.D., head of Research & Development and chief scientific officer, Baxalta. "At Baxalta, we are committed to expanding the availability of ONCASPAR globally, and this decision makes a curative treatment available to more patients across the world." Today, children in the U.S. diagnosed with ALL have a survival rate of more than 90 percent – a direct result of multi-agent chemotherapy treatments. ONCASPAR is a key component of these curative therapies. Currently, there have been national licenses granted to market ONCASPAR in Argentina, Belarus, Germany, Kazakhstan, Poland, Russia, Ukraine and the United States.
