All told, things are not looking good for this MS drug from Merck KGaA. It was rejected outright by the EU in Sep 2010 (#msg-54812455). In the US, Cladribine received an RTF letter in 2009; Merck KGaA resubmitted the NDA in Jun 2010 (#msg-51012919) and surprisingly received a priority-review designation from the FDA. However, the FDA’s new 3-month extension for completing the review effectively nullifies the priory-review status.
