A Study to Investigate How Effective and Safe Solifenacin Succinate Suspension is in Treating Children/Adolescents Aged 5 to Less Than 18 Years With Symptoms of Overactive Bladder (OAB) Compared to a Non-active Drug

Solifenacin succinate as a tablet formulation is already on the market for the treatment of symptoms of overactive bladder in adults. For the use in children and adolescent patients a new formulation of solifenacin has been developed.

This study investigated the effect and safety of solifenacin succinate liquid suspension compared to a non-active drug (placebo) over a 12-week period. The 2 weeks prior to the double blind period was a single-blind placebo run-in period in combination with behavioral urotherapy (Non-interventional diary assisted urotherapy consisting of overactive bladder (OAB) information, awareness, instruction, life-style advice and documentation of voiding habits and symptoms for OAB), followed by a 12 week daily treatment period. The study also investigated how well solifenacin succinate suspension is taken-up by the body and how long it stays in the body during this time.

Treatment and study plan

solifenacin succinate suspension

Drug

Children aged 5 to 11 years and adolescents aged 12 to 17 years received solifenacin succinate liquid suspension once a day orally via syringe for 12 weeks along with non interventional diary assisted urotherapy consisting of overactive bladder (OAB) information, awareness, instruction, life-style advice and documentation of voiding habits and symptoms for OAB. The initial dose started with the equivalent of 5 mg in adults, referred to as pediatric equivalent dose (PED) of 5 mg (PED5), based on body weight for three weeks and was titrated up or down in up to three titration steps of three weeks each to reach the optimal dose. Titration up or down could lead to weight-based doses equivalent to doses in adults of 2.5 mg, 5 mg, 7.5 mg or 10 mg once daily and were referred to as PED2.5, PED5, PED7.5 and PED10. The minimum dose was PED2.5, and the maximum dose was PED10. The decision to titrate up or down was made by the investigator using information from the 7 day patient diary.

Primary outcomes

  1. Change From Baseline to End of Treatment (EoT) in Mean Volume Voided (MVV) Per Micturition

    Time frame: Baseline and Week 12

    The mean voided volume was calculated from the participant diary data recorded during two measuring days (i.e., those days when the participant recorded the volume of each micturition) in the 7 days prior to the baseline and end of treatment visits. The MVV is equal to the mean of the non-zero volumes recorded over the 2 measuring days. A micturition is any voluntary urination, excluding episodes of incontinence.

Secondary outcomes

  1. Change From Baseline to End of Treatment in Daytime Maximum Volume Voided (DMaxVV) Per Micturition

    Time frame: Baseline and Week 12

    The mean daytime maximum volume voided (DMaxVV) was determined using the participant diary data recorded during two measuring days (i.e., those days when the participant recorded the volume of each micturition) in the 7 days prior to the Baseline and end of treatment visits. The daytime maximum volume voided (DMaxVV) is the largest (non-zero) volume recorded over both of the 2 measuring days in the diary. The first morning void is excluded from the calculation. Daytime is defined as the time between waking up in the morning and going to bed later the same day. A micturition is any voluntary urination, excluding episodes of incontinence.
