Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study was to assess the efficacy of Hibero (Mirabegron) versus active control (Ditropan: Oxybutynin Chloride) in the treatment of pediatric subjects (5 to \< 18 years of age) with overactive bladder. This study will further evaluate the safety of mirabegron in pediatric subjects with OAB after multiple dose adminstration.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The trial consists of four periods (Screening/ Washout (2 weeks); Baseline; 4 weeks from baseline; 8 weeks from baseline) excluding the safety monitoring period. It is a randomized, open label, parallel group, and active control comparator trial. The subject will be assigned either to Hibero (Mirabegron) 50 mg or Ditropan (Oxybutynin Chloride) 10 mg at baseline (randomization). The subject will be asked to take the IP or active comparator by mouth without crushing the pill for 8 weeks, and the frequency of oral administration depends on the prescribed method.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Hibero SR (Mirabegron) 50 mg

Subjects aged between 5 and 18 years will receive a daily dose of IP orally starting from baseline to week 8.

Group Type EXPERIMENTAL

Mirabegron 50 MG

Intervention Type DRUG

Mirabegron (IP: Hibero) is a beta-3 adrenergic agonist used to treat overactive bladder (OAB) and neurogenic detrusor overactivity (NDO). It is used to relax the smooth muscle of the bladder in the treatment of urinary frequency and incontinence. Through a 8 weeks clinical trial, it aims to evaluate the efficacy and safety of Hibero (Mirabegron), especially in maximum voided volume.

Ditropan (Oxybutynin Chloride) 10 mg

Subjects aged between 5 and 18 years will receive a daily dose of active comparator orally starting from baseline to week 8.

Group Type ACTIVE_COMPARATOR

Oxybutynin Chloride 5 MG

Intervention Type DRUG

Oxybutynin has been used to treat overactive bladder (OAB). The subject will take 5 mg of Ditropan (Oxybutynin Chloride) twice a day, in total of 10 mg for 8 weeks.
