Discovery history and clinical development of mirabegron for the treatment of overactive bladder and urinary incontinence

Introduction: Overactive bladder (OAB) and urinary incontinence, although not life-threatening, are very bothersome chronic health conditions. The limitations of current pharmacological treatment urge the need for novel drugs with alternative mechanisms of action. Huge efforts in this area of research led to the synthesis of several selective and potent β3-adrenoceptor agonists that gained relevance through research during the late 80s and 90s. Mirabegron was the first compound of this new class of drugs that showed preclinical efficacy in several models of storage bladder dysfunction, together with a favorable human pharmacological profile. Having passed the proof-of-concept stage, an extensive clinical development and pharmacology program was performed during the last 10 years, involving > 10,000 individuals, before mirabegron was granted marketing approval. Areas covered: In this case history, the authors review the milestones in mirabegrons discovery based on a systematic literature review. Expert opinion: Thanks to its tolerability and safety/efficacy balance, mirabegron has potential to fill a need for new treatment options for OAB, and paves the way for further development of a completely new class of drugs aimed to treat this condition. However, the exact role of mirabegron in clinical practice has yet to be defined. Further studies are needed in order to clarify, together with post-launch information, critical safety issues and cost-effectiveness in head-to-head comparison with current standard treatments.

Social, economic, and health utility considerations in the treatment of overactive bladder.

Overactive bladder (OAB) is a highly prevalent urinary syndrome with a profound impact on quality of life (QoL) of affected patients and their family because of its adverse effects on social, sexual, interpersonal, and professional function. Cost-of-illness analyses showed the huge economic burden related to OAB for patients, public healthcare systems, and society, secondary to both direct and indirect costs; however, intangible costs related to QoL impact are usually omitted from these analyses. Recently many novel treatment modalities have been introduced and the need to apply the modern methodology of health technology assessment to these treatment strategies was immediately clear in order to evaluate objectively their value in term of both improvement in length/quality of life and costs. Health utilities are instruments that allow a measurement of QoL and its integration in the economic evaluation using the quality-adjusted life-years model and cost-utility analysis. The development of suitable instruments for quantifying utility in the specific group of OAB patients is vitally important to extend the application of cost-utility analysis in OAB and to guide healthcare resources allocation for this disorder. Studies are required to define the cost-effectiveness of available pharmacological and nonpharmacological therapy options for this disorder.
