    General information about the trial
    Main objective of the trial
    To evaluate the efficacy and safety of solifenacin succinate once daily (o.d.) in children and adolescents with Overactive Bladder (OAB).
    Protection of trial subjects
    This clinical study was written, conducted and reported in accordance with the protocol, ICH GCP Guidelines, and applicable local regulations, including the European Directive 2001/20/EC, on the protection of human rights, and with the ethical principles that have their origin in the Declaration of Helsinki. Astellas ensures that the use and disclosure of protected health information (PHI) obtained during a research study complies with the federal and/or regional legislation related to the privacy and protection of personal information.
    Background therapy
    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.

    Recruitment
    Recruitment details
    The study population consisted of male and female children (5 to 11 years old) and adolescents (12 to 17 years old) with overactive bladder (OAB).

    Pre-assignment
    Screening details
    Subjects received 4 weeks of urotherapy (standard first line therapy for pediatric OAB patients). Two weeks after start of urotherapy a single-blind 2-week placebo run-in period began. After run-in period eligible subjects were randomized to 12 weeks of double-blind treatment (solifenacin succinate suspension or placebo) and continued urotherapy.

    Children aged 5 to 11 years received matching placebo 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.

    Notes
    [1] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left.
    Justification: The SAF consisted of all participants who received at least 1 dose of double-blind study medication and for whom any safety data were reported after first dose of study drug. The subject non-completion reasons listed explain and add up to the not completed milestone number. If the not completed number is added to the completed number this equals the number of subjects in the started milestone.

The not completed number includes the subjects not included in the SAF and are listed as subject noncompletion reasons. If the not completed number is added to the completed number this equals the number started.

    Mean Volume Voided (MVV) per Micturition
    Values for this baseline characteristic are based on the Full Analysis Set (FAS). The FAS consisted of all randomized patients that took at least 1 dose of double-blind study medication after randomization and provided a valid baseline and post baseline value for the primary efficacy endpoint. A micturition is any voluntary urination, excluding episodes of incontinence only. Micturitions voided volumes were recorded in a patient diary for any 2 days in the 7 day period prior to the baseline visit (referred to as "measuring days"). The number of participants was 70; 73; 19; 21 per arm.

    Daytime Maximum Volume Voided (DMaxVV)
    FAS population. The mean DMaxVV was determined using the patient diary data recorded during two measuring days (i.e., days when the patient recorded the volume of each micturition) in the 7 days prior to the baseline visit. The DMaxVV is the largest (non-zero) volume recorded over both of the 2 measuring days in the diary. 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 only. The number of participants was 70; 73; 19; 21 per treatment arm.

    Change From Baseline to End of Treatment (EoT) in Mean Volume Voided (MVV) Per Micturition
    End point description
    The mean voided volume was calculated from the patient diary data recorded during two measuring days (i.e., those days when the patient 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. Study analysis population for this endpoint consisted of the Full Analysis Set (FAS). The FAS consists of all randomized patients that took at least one dose of double-blind study medication after randomization and provided both valid baseline and post-baseline values for the primary efficacy endpoint. Missing values at End of Treatment (EoT) were imputed using the last observation carried forward (LOCF) method.

    Change From Baseline to End of Treatment in Daytime Maximum Volume Voided (DMaxVV) Per Micturition
    End point description
    The mean daytime maximum volume voided (DMaxVV) was determined using the patient diary data recorded during two measuring days (i.e., those days when the patient 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. 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. The study analysis population for this endpoint consisted of the FAS population. Missing values at EoT were imputed using the LOCF method.

    Change From Baseline to End of Treatment in Mean Number of Daytime Micturitions Per 24 Hours
    End point description
    The mean number of micturitions was determined using the patient diary data recorded by the participant in the 7 days prior to baseline visit and end of treatment visit. A micturition is any voluntary urination, excluding episodes of incontinence. The study analysis population for this endpoint consisted of the FAS population. Missing values at EoT were imputed using the LOCF method. Daytime is defined as the time between waking up in the morning and going to bed later the same day.

    Change From Baseline to End of Treatment in Mean Number of Grade 3 or 4 Urgency Episodes Per 24 Hours in Adolescents [27]
    End point description
    Adolescent participants were asked to record the degree of urgency associated with each micturition and incontinence episode according to the Patient Perception of Intensity of Urgency Scale (PPIUS) scale (0 - no urgency, 1 - mild urgency, 2 - moderate urgency, 3 - severe urgency, 4 - urge incontinence). The mean number of grade 3 or 4 urgency episodes was determined using diary data recorded by the participant in the 7 days prior to baseline visit and end of treatment visit. The study analysis population for this endpoint consisted of the FAS population (adolescents only). Missing values at EoT were imputed using the LOCF method.
