The US Food and Drug Administration (FDA) has accepted for review the Genzyme's resubmission of supplemental Biologics License Application (sBLA) seeking approval of Lemtrada (alemtuzumab) for the treatment of relapsing forms of multiple sclerosis.  A six-month review period has been assigned for the Lemtrada sBLA. Genzyme expects FDA action on the sBLA in the fourth quarter.

This resubmission is based on data from the same clinical studies included in the original sBLA, and provides supplemental analyses and additional information to specifically address issues previously noted by the FDA in its December 27, 2013 Complete Response Letter. The company resubmitted the sBLA earlier this month following constructive discussions with the agency.

Genzyme has pioneered the development and delivery of transformative therapies for patients affected by rare and debilitating diseases for over 30 years.
