Tokyo, March 9, 2018 - Astellas Pharma Inc. (President and CEO: Yoshihiko Hatanaka, “Astellas”) today announced that solifenacin succinate (generic name, “solifenacin”) oral suspension received approval in Europe for the treatment of neurogenic detrusor overactivity (NDO) in pediatric patients aged 2 to 18 years. This approval was received in European 31 countries including the Netherlands which was the Reference Member State by Decentralized Procedure which is a type of Mutual Recognition.

NDO, in which a neurologic defect can impair the signaling between the bladder and the central nervous system and cause uncontrolled urination, is associated with certain neurological conditions, such as multiple sclerosis or a spinal injury. In children, a congenital neural tube defect1, such as spina bifida2, is the most common cause of NDO.3

The dosage form of solifenacin oral suspension was approved in 2015 for the use in adults with overactive bladder with symptoms of urgency, frequency, and urge incontinence based on bioequivalence with solifenacin tablets which was approved in Europe in 2004. Current approval is addition of a pediatric indication. The solifenacin oral suspension will be available for pediatric patients with NDO aged 2 to 18 years in a 1 mg/1 mL dose oral suspension. Solifenacin are being sold in more than 80 countries worldwide4.

Astellas is pleased to deliver Solifenacin oral suspension to pediatric patients to further enhance its contributions to the treatment of NDO in the future.

The approval will have no impact on the consolidated financial forecasts for the fiscal year 2017 ending March 2018.
