Cangene Announces Withdrawal of Marketing Authorization Application for Investigational Hemophilia Compound IB1001 in Europe
Intends to Re-File with Additional Clinical Data
WINNIPEG, June 13, 2013 /CNW/ - Cangene Corporation (Cangene) today announces its withdrawal of the Marketing Authorization Application (MAA) for hemophilia compound IB1001 in Europe and intention to re-file the MAA with the additional clinical data requested by the European Medicines Agency (EMA).
In February 2013, Cangene acquired all rights to the development of the investigational hemophilia compound IB1001 from Ipsen and Inspiration Biopharmaceuticals Inc. IB1001 is a recombinant Factor IX (rFIX) product being developed for the treatment and prevention of bleeding episodes with hemophilia B. At the time of the acquisition, the asset was under regulatory review by the U.S. Food and Drug Administration (FDA) and in the latter stages of review by the EMA.
In May 2013, Cangene presented an Oral Explanation of IB1001 at the Committee for Medicinal Products for Human Use (CHMP). The EMA subsequently requested additional clinical data for IB1001 as part of the Marketing Authorization Application's Centralised Procedure. Given the results of the clinical study producing the data requested will not be available within the timeframe allowed in the Centralised Procedure, Cangene has notified the EMA of its withdrawal of the application at this time. Cangene intends to re-file the MAA for European Union licensure of this important product for hemophilia B patients when the additional clinical data is available.
Cangene continues to address the FDA issued Complete Response Letter (CRL) with a clearly defined path to approval in connection with the Biologics License Application (BLA).
IB1001 is an intravenous recombinant FIX (rFIX) product being developed for the treatment and prevention of bleeding in individuals with hemophilia B. A Biologics License Application (BLA) was submitted to the United States Food and Drug Administration in April 2012, while in August 2011, a Marketing Authorization Application (MAA) was submitted to the European Medicines Agency. In July 2012, IB1001 was put on a clinical hold by the FDA due to a higher than expected rate of host cell antibody development in people treated with IB1001. Manufacturing process changes have been implemented for the drug substance leading to significant reduction in the levels of HCP. Comparability data on drug substance manufactured using the former and the modified processes confirm that the process changes have been successful. Work is ongoing to remove the clinical hold. The FDA issued a Complete Response Letter (CRL) in February 2013 in connection with the BLA for IB1001 and additional manufacturing and development information will be required for the BLA. No additional clinical data was requested under the CRL.
About Hemophilia B
Hemophilia B, previously known as "Christmas disease," is a rare, inherited disorder occurring in about one in 25,000 male births annually. Approximately 25,000 people worldwide, including more than 4,000 in the U.S., have been diagnosed with hemophilia B. Hemophilia B patients have an impaired ability of their blood to clot, which is caused by having substantially reduced or no FIX activity. People with hemophilia B need FIX injections to restore normal blood coagulation and prevent frequent bleeding that could otherwise result in pain, irreversible joint damage and life-threatening hemorrhages. Currently, prophylaxis in hemophilia B typically requires multiple injections of FIX to maintain adequate levels of clotting factor in the blood.
