Study summary

This single-dose study will investigate how well solifenacin suspension is taken up, how long it stays in the body and how well it will be tolerated in children and adolescents aged 5-17 years with symptoms of overactive bladder.

Read the detailed description

This is a multicenter, open-label, sequential, single ascending dose study. The study will consist of three treatment groups in children and three treatment groups in adolescents, targeting equivalent exposure to the 2.5, 5 and 10 mg doses o.d. in adults at steady state. The study will be conducted in pediatric OAB patients to establish the single-dose PK and the acute safety profile of solifenacin aqueous suspension. Each of the six groups will consist of at least six patients.

The study will start with the lowest dose group in adolescent patients (12 to 17 years). When this group has completed the study, their safety and concentration data will be reviewed by a Safety Review Committee. If no safety concerns are evident according to pre-specified criteria, enrollment of children (5 to 11 years) in the lowest dose group and adolescents in the intermediate dose group will be started simultaneously. When these groups have completed the study, their safety data and drug concentration data will also be reviewed. If no safety concerns occurred, enrollment of children in the intermediate dose group and of adolescents in the highest dose group will be started simultaneously. Finally, after these groups completed the study and no safety concerns occurred during associated data review, enrollment of children in the highest dose group will start. Interim review of plasma exposure at lower doses will be used to adjust the next higher doses administered, if necessary.

Interventions

  • DrugSolifenacin succinate suspension 2.5 mg

    Adolescents and children are given a single dose of solifenacin succinate liquid suspension orally via syringe in the morning of day 1 followed by a glass of water. Doses are calculated per weight of the participant, targeting to have equivalent doses of 2.5 mg of solifenacin once daily in adults.

    Time frame: Day 1 predose up to Day 7 postdose

  3. Apparent Terminal Elimination Half-life (t1/2)

    Time frame: Day 1 predose up to Day 7 postdose

  4. Time to Attain Cmax (tmax)

    Time frame: Day 1 predose up to Day 7 postdose

    Time frame: Day 1 predose up to Day 7 postdose

  7. Apparent Volume of Distribution During the Terminal Phase (Vz/F)

    Time frame: Day 1 predose up to Day 7 postdose

Secondary outcomes

  1. Number of Participants with Adverse Events (AEs)

    Safety is monitored by collecting AEs, which includes abnormal laboratory tests, vital signs or ECG data that are defined as an AE if the abnormality induces clinical signs or symptoms, requires active intervention, interruption or discontinuation of study medication or is clinically significant in the investigator's opinion. A treatment-emergent adverse event (TEAE) is defined as an AE that occurs or worsens after study drug administration. A serious AE (SAE) is any untoward medical occurrence that, at any dose: Results in death, is life-threatening, results in persistent or significant disability/incapacity, results in congenital anomaly, or birth defect, requires inpatient hospitalization or leads to prolongation of hospitalization or other medically important events.

    Time frame: From the first dose of study drug up to 7 days postdose

  2. Change from baseline in postvoid residual (PVR) volume

    PVR volume is assessed by ultrasonography or bladder scan.

    Time frame: Baseline (screening) and 4 hours postdose
