Mirabegron: Pediatric First Approval
Additional information about this Adis Drug Review can be found here
Mirabegron (MYRBETRIQ®), a beta-3 adrenergic agonist developed by Astellas Pharma Inc., is well established as a treatment for overactive bladder in adults and is available as extended-release (ER) tablets administered once daily. More recently, mirabegron has been investigated in pediatric patients with neurogenic detrusor overactivity (NDO) and received its first approval in this indication in pediatric patients aged ≥ 3 years on 25 March 2021. In addition to mirabegron ER tablets (which can be used in pediatric patients weighing ≥ 35 kg), mirabegron is available as an ER oral suspension (MYRBETRIQ® Granules) for pediatric patients; in those weighing < 35 kg, only the ER oral suspension formulation should be used. The ER tablet and ER oral suspension formulations are not substitutable on a mg-by-mg basis. This article summarizes the milestones in the development of mirabegron for NDO leading to this pediatric first approval.
