Study summary

This was a multicenter, randomized, double-blind, parallel-group, multiple-dose study to evaluate the efficacy and safety of BOTOX in adolescents with urinary incontinence due to overactive bladder (OAB) with inadequate management with anticholinergic therapy. Participants were randomized in a 1:1:1 ratio to receive a single Tx of 25 U, 50 U, or 100 U BOTOX (not to exceed 6 U/kg) on Day 1, were seen after each treatment at Weeks 2, 6, and 12 post-treatment, and thereafter at alternating telephone and clinic visits every 6 weeks until they qualified for further retreatment/exited the study. Participants could receive multiple treatments dependent upon the number and timing of patient requests/qualification for retreatment. At each retreatment the investigator could keep the dose the same or increase it one dose level in a blinded fashion. Participants exited the study once 96 weeks have elapsed since entry on Day 1 and at least 12 weeks follow-up since their last study treatment had occurred.

  • Experimental
    Botox 25 U

    Participants randomized to receive 25 Units (U) BOTOX (not to exceed 6 U/kg), administered via cystoscopy as 20 intradetrusor injections of 0.5 mL each, sparing the trigone.

Interventions

  • BiologicalBOTOX®

    Each vial of BOTOX (Botulinum Toxin Type A) purified neurotoxin complex, formulation No. 9060X contains 100 U of Clostridium botulinum toxin Type A, 0.5 mg albumin (human), and 0.9 mg sodium chloride in a sterile, vacuum-dried form without a preservative. The study medication was to be reconstituted with 0.9% sodium chloride (preservative-free). The 10 mL of study drug was to be administered as 20 injections each of 0.5 mL. Under direct cystoscopic visualization, injections were to be distributed evenly across the detrusor wall and spaced approximately 1 cm apart. To avoid injecting the trigone, the injections were to be at least 1 cm above the trigone. The injection needle was to be inserted approximately 2 mm into the detrusor for each injection.

    Also known as: Botulinum Toxin Type A

What researchers measure

Primary outcomes

  1. Change From Study Baseline in the Daily Normalized Daytime Average Number of Urinary Incontinence Episodes in Treatment Cycle 1

    Urinary incontinence was defined as involuntary loss of urine as recorded by the participant in a bladder diary during 2 consecutive days in the week prior to the study visit (normalized to a 12 hour daytime period). Daytime is defined as the time between waking up to start the day and going to bed to sleep for the night. The number of daily daytime incontinence episodes were averaged during the 2-day period.

Other outcomes

  1. Number of Participants With Treatment Emergent Adverse Events

    An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study drug. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent adverse events/treatment-emergent serious adverse events (TEAEs/TESAEs) are defined as any event that began or worsened in severity on or after the first dose of study drug.

    Time frame: From the first dose of study drug until the last dose, up to 147 weeks

The Modified Treatment Benefit Scale (Modified TBS) is a single-item scale designed to assess the change in the participant's overactive bladder (OAB) condition following treatment. The participant's current condition (urinary problems, urinary incontinence) is compared to their condition prior to receipt of any study treatment by selection of "greatly improved", "improved", "not changed" or "worsened". Participants who selected "greatly improved" or "improved" were considered to have a positive treatment response.

Other pre-specifiedNumber of Participants With Treatment Emergent Adverse Events

An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study drug. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent adverse events/treatment-emergent serious adverse events (TEAEs/TESAEs) are defined as any event that began or worsened in severity on or after the first dose of study drug.

Time frame:
From the first dose of study drug until the last dose, up to 147 weeks
