The rapporteur appointed was D. Murphy and the co-rapporteur was F. Hasslung Wikström.

In its letter notifying the Agency of the withdrawal of application, the applicant stated the reason for the withdrawal: CVMP considered that the data provided do not allow the Committee to conclude on a positive benefit-risk balance.
