Abstract
Background: Mirabegron, the first β-3 adrenergic receptor agonist, received approval from the Food and Drug Administration (FDA) in 2012 for the treatment of overactive bladder (OAB). This pharmacovigilance study investigated the safety profile of mirabegron treatment using the US FDA Adverse Event Reporting System (FAERS) database. Methods: This study employed disproportionality analyses, including the reporting odds ratio (ROR) and Bayesian Confidence Propagation Neural Network (BCPNN) algorithm, to quantify signals of adverse events associated with mirabegron. Results: From the first quarter of 2012 to the third quarter of 2023, a comprehensive total of 14,356,234 adverse event (AE) reports were submitted to the FDA Adverse Event Reporting System database. Within this dataset, encompassing 18,763 reports specifically associated with mirabegron, healthcare professionals notably contributed 2,902 of these reports. A total of 80 preferred terms (PTs) of interest were identified using both the ROR and information component algorithms. The most common AEs included blood pressure increased, urinary retention, atrial fibrillation, dry mouth, and tachycardia, which were consistent with the product instructions. Unexpected significant AEs, such as arrhythmia, palpitations, dementia, transient ischemic attack, Parkinson's disease, anti-neutrophil cytoplasmic antibody positive vasculitis, lip swelling, and swollen tongue, were also identified. The study findings indicated that the majority of onset time occurred within 30 days (n = 358, 55.68%). However, AEs were still possible after 1 year of mirabegron treatment. Conclusion: This study provided valuable evidence for the real-world safety of mirabegron, helping clinical professionals enhance their understanding of mirabegron's safety in clinical practice. It also contributed valuable evidence for further safety studies on mirabegron.

Abstract
INTRODUCTION Neurogenic lower urinary tract dysfunction (NLUTD) in children can cause renal failure and urinary incontinence if not treated sufficiently. Antimuscarinics (AM) and intradetrusor botulinum toxin injections (BoNT-A) with clean intermittent catheterization (CIC) are widely used treatment options for children with NLUTD. However, a considerable number will become refractory to these treatment options. This study aimed to evaluate the efficacy and long-term outcomes of mirabegron in children with NLUTD as an add-on and as a stand-alone treatment. MATERIAL AND METHODS Patients under 18 years of age with NLUTD who were refractory to AM and/or BoNT-A and were treated with mirabegron 50 mg were retrospectively studied. Mirabegron was either used as monotherapy or in addition to AM and/or BoNT-A. Video-urodynamic studies (VUDSs) were performed before and after treatment with mirabegron. Changes in video-urodynamic parameters, the need for other NLUTD therapy during follow-up, patient-reported side effects, and urinary incontinence were outcomes of interest. RESULTS A total of 34 patients with NLUTD were included. All patients were on CIC and the median age was 13.1 years (IQR 15.9-10.3). Median follow-up was 31.4 months (IQR 57.4-11.4). Bladder compliance improved by 89.9%, from 14.9 to 28.3 ml/cm H2O (p-value<0.001). Maximum cystometric capacity, end-filling detrusor pressure, volume at first detrusor overactivity, vesicoureteral reflux, and urinary incontinence significantly improved after mirabegron. The add-on therapy group showed more significant improvements in video-urodynamic outcomes compared to the monotherapy group. The median time of requiring other NLUTD therapy was 25.5 months (IQR 39.8-14.8). None of the included patients reported side effects. CONCLUSIONS Mirabegron is an effective treatment for children with therapy-refractory NLUTD with an average efficacy of 2 years after which additional therapy is required. Despite the retrospective character of this study, our results confirm the beneficial effect of mirabegron in children with therapy-refractory NLUTD, in particular when mirabegron is used as add-on therapy in those with low-compliance bladders.

Abstract
This study was to investigate urinary beta 3-adrenoceptor concentration as a biomarker for overactive bladder (OAB) and predictor of treatment outcomes in women receiving the beta 3-adrenoceptor agonist mirabegron. The study comprised 50 women identified with OAB and 35 women considered as healthy controls. All women with OAB received daily dosage of 50 mg of mirabegron for 12 weeks. Bladder diaries, OAB-related questionnaires, and global response assessment scale (GRAS) data were collected. Urinary beta 3-adrenoceptor concentration was measured through enzyme-linked immunosorbent assay. All OAB-related questionnaires and GRAS indicated improved posttreatment urinary health. After mirabegron treatment, the frequency of micturition and urgency episodes decreased, but the urinary beta 3-adrenoceptor/creatinine (Cr) ratio increased. The urinary beta 3-adrenoceptor/creatinine ratio was identified as a sensitive biomarker for OAB with a confidence interval of 0.656 to 0.856 (p < 0.001). A negative correlation (- 0.431, p = 0.040) between this biomarker and health-related quality of life (HRQL) scores. The Beta 3-adrenoceptor/Cr levels increased significantly in the treatment-responsive group, while they remained unchanged in the unsatisfactory outcome group. This study shows that 12 weeks of mirabegron treatment improves OAB symptoms and HRQL. Furthermore, urinary beta 3-adrenoceptor concentration may be a diagnostic biomarker for OAB.

Abstract
Overactive bladder (OAB) is characterized by urinary urgency and increased urinary frequency, substantially affecting quality of life. Tamsulosin and mirabegron combination therapy has been studied as a safe and effective treatment option for patients with OAB. This study evaluated the effects of combining these two drugs on their pharmacokinetics and safety profiles in healthy Korean males. In this open-label, fixed-sequence, three-period, drug-drug interaction phase 1 study, a total of 36 male participants were administered multiple doses of tamsulosin alone (0.2 mg once daily), mirabegron alone (50 mg once daily), or a combination of both drugs. The results showed that the combination of tamsulosin and mirabegron increased tamsulosin exposure in the plasma by approximately 40%. In contrast, the maximum plasma concentration of mirabegron was reduced by approximately 17% when administered with tamsulosin. No clinically significant changes in the safety profiles, vital signs, or clinical laboratory test results were observed in this study. In conclusion, there were no clinically relevant drug-drug interactions between tamsulosin and mirabegron in terms of pharmacokinetics, safety, and tolerability, suggesting that their combination could be a promising treatment option for patients with OAB.

Abstract
INTRODUCTION Overactive bladder (OAB) is a common syndrome in adults. Current pharmacologic treatment includes antimuscarinic agents and β-3 adrenoceptor agonists. For non-responders to oral medication, intravesical injection of botulinum toxin A (BoNT-A) is an effective option. However, these treatments have potential adverse events and should be cautiously selected for appropriate patients. This review presents the recently published results of clinical trials and studies for patients with OAB and the underlying pathophysiology of OAB. Appropriate medical therapy based on pathophysiology of OAB is also presented. AREAS COVERED Literature search from Pubmed from 2001 to 2023 including clinical background, pharmacology, and clinical studies for OAB medications. EXPERT OPINION Treatment of OAB syndrome with any antimuscarinic or β-3 adrenoceptor agonist is feasible as a first-line approach. For patients with suboptimal therapeutic effect to full-dose antimuscarinics or mirabegron, combination with both drugs can improve efficacy. Intravesical BoNT-A 100-U injection provides therapeutic effects for refractory OAB. Patients who are refractory to initial pharmacotherapies should be investigated for the underlying pathophysiology; then an appropriate medication can be added, such as an α1-blocker or anti-inflammatory agents. Patient education about behavioral modification and therapies should always be provided with oral medication or BoNT-A injection for OAB patients.

Abstract
This randomized clinical trial evaluates the success rate of neuro-adaptive therapy (NAT), applied with a specific neuro-adaptive regulator device, the Self-Controlled Electro Neuro-Adaptive Regulation (SCENAR), versus a sham for urge incontinence due to an overactive bladder (OAB). From February 2019 to May 2021, 66 patients were recruited. All subjects were randomized 1:1 at the first intervention visit to the NAT or sham procedure. Inclusion criteria were females between 18 and 80 years old with leakages due to an overactive bladder with unresponsiveness to medical therapy. Subjects were scheduled to receive up to eight weekly 20 min intervention sessions to obtain a complete (CR) or partial response (PR). Patients with no response after three sessions were considered as a failure. The primary end point of this trial was to assess the efficacy of NAT compared to an inactive sham intervention, evaluated 1 month after the last session. Analysis showed 23 (70%) patients responded (20 complete and 3 partial response) in the NAT group compared to 16 (48%) patients (all complete response) in the placebo arm (p = 0.014). Significant differences were maintained after the intervention, with persistent response at 3 months in 19 (58%) patients after active treatment and 14 (42%) after the placebo (p < 0.001), and at 6 months in 18 (55%) vs. 11 (33%) (p = 0.022), respectively. The number of sessions to achieve CR was similar in both arms, with 4.3 ± 1.9 in NAT and 3.9 ± 1.8 in the sham group (NS). Significant differences were observed between both groups for patients' satisfaction (p = 0.01). The binary model selected age as a predictor of response at the last follow-up. The odds ratio indicates that each year of increase in age, the probability of a positive response to treatment at 6 months decreases 0.95 (95% CI 0.9-0.99) times (p = 0.03). In conclusion, this pilot randomized trial gives evidence that neuro-adaptive electrostimulation is effective to treat refractory urge urinary incontinence due to OAB. The security and long-term efficacy of this treatment merits further evaluation. Moreover, its favorable profile and the economic advantages of the device make the evaluation of this promising technique mandatory in a primary therapeutic scenario.

Abstract
Lower urinary tract symptoms (LUTS), including urgency, frequency, and urgency incontinence, are highly prevalent in the general population and increase in prevalence with increasing age. All LUTS, but notable urgency and urgency incontinence, are associated with negative impact on quality-of-life (QoL), with multiple aspects of QoL affected. Urgency and urgency incontinence are most commonly caused by overactive bladder (OAB), the clinical syndrome of urinary urgency, usually accompanied by increased daytime frequency and/or nocturia in the absence of infection or other obvious etiology, which may be treated with conservative and lifestyle interventions, bladder antimuscarinic drugs, and, more recently, by mirabegron, a β3 agonist. This narrative review describes the impact of OAB on QoL, quantifies this impact, and outlines the evidence for the use of mirabegron in the treatment of, and improvement in QoL in, people with OAB.

Abstract
Objective We aimed to evaluate the efficacy and safety of mirabegron monotherapy in very older (>80 years) women with overactive bladder (OAB) who were discontinued anticholinergic drugs by the other departments. Material and methods The present retrospective study evaluated very older (>80 years) women with OAB who were discontinued anticholinergic drugs by the other departments between May 2018 and January 2021. Efficacy assessments were performed using Overactive Bladder-Validated Eight-Question (OAB-V8) scores before and after mirabegron monotherapy (12 weeks). Safety was evaluated based on adverse events (hypertension, nasopharyngitis, and urinary tract infection), electrocardiography, hypertension measure, uroflowmetry (UFM), and post-voiding. Patient data including demographic characteristics, diagnoses, values before and after mirabegron monotherapy, and adverse events were evaluated. Results A total of 42 very older (>80 years) women with OAB who used mirabegron monotherapy (50 mg per day) were included in this study. Frequency, nocturia, urgency, and total OAB-V8 scores were significantly lower after mirabegron monotherapy than before mirabegron monotherapy (p < 0.05, p < 0.05, p < 0.05, and p < 0.05, respectively). There was no significant difference between systolic-diastolic blood pressure and heart rate before and after mirabegron monotherapy treatment. Conclusion Mirabegron monotherapy is an effective and safe therapy in very older (>80 years) women with OAB.

Abstract
Objectives To evaluate the effects of mirabegron in the treatment of overactive bladder syndrome (OAB) after radical prostatectomy (RP). Patients and methods A total of 108 post-operative RP patients were randomly assigned to either the mirabegron (study) or the placebo (control) group. The Overactive Bladder Syndrome Self-Assessment Scale (OABSS) was selected as the primary endpoint, and the International Prostate Symptom Score (IPSS) and Quality of Life (QOL) score were selected as secondary endpoints. Statistical analysis was performed using IBM SPSS Statistics 26, and the treatment effects were compared between the two groups using independent samples t-test. Results In total, 55 patients were included in the study group and 53 patients in the control group. The mean age was(70.08 ± 7.54)years. There was no statistical difference in the baseline data between the two groups. OABSS scores decreased significantly in the study group compared to the control group during drug treatment (6.67 ± 1.06 vs. 9.14 ± 1.83, p < 0.01) and were better than the control group during the follow-up at week 8 and week 12. In addition, the decrease in IPSS scores (11.29 ± 3.89 and 15.34 ± 3.54, p<0.01) and the increase in QOL scores (2.40 ± 0.81 vs. 3.20 ± 1.00) were statistically significant in the study group. And the patients in the study group had better improvement in voiding symptoms and quality of life than the control group during the follow-up period. Conclusion Daily administration of 50 mg mirabegron after RP surgery significantly improved the symptoms of OAB after surgery with fewer side effects. Additional randomized controlled trials should be conducted in the future to further evaluate the efficacy and safety of mirabegron.

Abstract
Background Few randomized controlled trials evaluate the long-term efficacy and safety of pharmacotherapy for overactive bladder (OAB). This network meta- analysis compares the long-term (52-week) efficacy and safety of vibegron, mirabegron and anticholinergics for the treatment of OAB. Methods A systematic literature review and network meta-analysis were conducted following PRISMA guidelines using MEDLINE, Embase and Cochrane Central Register of Controlled Trials and terms related to OAB. Efficacy outcomes included change from baseline to week 48–52 in mean daily total urinary incontinence (UI) episodes, mean daily number of micturitions and volume voided/micturition. Efficacy outcomes were analysed using Bayesian models. Commonly reported adverse events (AEs) are described. Results Of 2098 hits retrieved, 5 publications and 1 study report describing 5 unique randomized controlled trials were included in the analyses. Mean (95% credible interval) change from baseline in total UI episodes for vibegron 75 mg (−2.2; −2.9 to −1.5) showed a significantly greater reduction than mirabegron 50 mg (−1.3; −1.9 to −0.8) and tolterodine 4 mg extended release (−1.6; −2.1 to −1.1). No significant differences were observed between vibegron and comparators for daily micturitions or volume voided/micturition. Within the manuscripts, the 4 most common AEs (range) for anticholinergics included dry mouth (5.2–90.0%), constipation (7.7–65.0%), blurred vision (3.8–35.0%) and hypertension (8.6–9.6%); the 4 most commonly reported AEs for β3-adrenergic agonists included hypertension (8.8–9.2%), urinary tract infection (5.9–6.6%), headache (5.5%) and nasopharyngitis (4.8–5.2%). Conclusion Vibegron was associated with significantly greater improvement in daily total UI episodes at 52 weeks than mirabegron and tolterodine. When reported, the most common AE for anticholinergics was dry mouth and for β3-adrenergic agonists was hypertension. Hypertension incidence was similar between drug classes.

Abstract
BACKGROUND Overactive bladder (OAB) is associated with considerable clinical and economic burden. Treatment of patients with OAB using anticholinergics is limited by tolerability issues and increased anticholinergic burden, which is associated with increased risk of dementia and falls/fractures. This analysis assessed the budget impact of introducing the β3-adrenergic agonist vibegron for the treatment of patients with OAB from US commercial payor and Medicare perspectives. METHODS A budget impact model (BIM) with a 5-year time horizon was developed using a top-down, prevalence-based approach and projected market shares for 1-million-member US commercial and Medicare plans. The BIM included vibegron, mirabegron, and anticholinergics, incorporating changes in clinical outcomes (efficacy, drug-drug interactions, anticholinergic burden (ACB), OAB-related comorbidities, and adverse events (AEs)). Costs per member per month (PMPM) and per treated member per month (PTMPM) were determined. One-way sensitivity analyses quantified the impact of changes in key variables. RESULTS The introduction of vibegron was associated with a modest increase in PMPM cost over 5 years of $0.12 (range for years 1‒5, $0.01‒$0.26) for commercial payors and $0.24 ($0.01‒$0.52) for Medicare (PTMPM cost: $2.70 ($0.17‒$4.85) and $3.15 ($0.19‒$5.82), respectively). Costs were partially offset by savings related to decreased third-line treatment use, yearly decreases in AE and comorbidity incidence, reduced drug-drug interactions, and reduced ACB associated with vibegron introduction. PMPM costs were most sensitive to vibegron market share assumptions, OAB prevalence, and vibegron persistence at 1 month for private payors and Medicare and additionally vibegron persistence at 12 months for Medicare. CONCLUSIONS Vibegron may address unmet needs in treating OAB and is a useful addition to health plans while minimizing risks of anticholinergic AEs, ACB, and drug-drug interactions, which may partially offset increased pharmacy costs.

Abstract
BACKGROUND Overactive bladder (OAB) is defined as urinary urgency, usually with urinary frequency and nocturia, with or without urgency urinary incontinence. OAB can interfere with health-related quality of life. The current treatment for OAB includes conservative management, surgery, and pharmacotherapy. Mirabegron is a new drug acting by the mechanism of ß3-adrenoceptor agonism. This study aimed to review the cost-effectiveness of mirabegron in the treatment of OAB. AREAS COVERED We searched published articles in electronic search databases. Ten studies were included in the qualitative analysis. Various antimuscarinics, including oxybutynin, fesoterodine, tolterodine, darifenacin, and trospium were compared with mirabegron. The results were evaluated and compared according to the quality-adjusted life-years (QALY), cost/year, and incremental cost-effectiveness ratio (ICER). Of the ten studies in only three, mirabegron was not a cost-effective strategy. In seven cases, mirabegron was cost-effective. EXPERT OPINION : Based on our findings, the cost-effectiveness of mirabegron was variable in different regions; however, most of the studies show the cost-effectiveness of mirabegron. Our study illustrates that mirabegron's incremental cost-effectiveness ratio in comparison with its comparators is below the willingness to pay threshold even in the countries with low GDP/Capita. The results also showed that despite the low price and no difference in the effectiveness of mirabegron compared to antimuscarinic drugs, the sensitivity of the study results to adverse effects and supportive therapeutic interventions for patients treated with antimuscarinic drugs. Our proposal for future economic studies for OAB pharmacotherapy is to compare different doses, formulations, and administration forms in a real-world context.

Abstract
The study aims to elucidate the impact of mirabegron versus solifenacin on autonomic function and peripheral arterial conditions in women with overactive bladder syndrome (OAB). All consecutive women with OAB were randomized to receive 12 weeks of mirabegron 25 mg or solifenacin 5 mg once per day. Heart rate variability, cardio-ankle vascular index, ankle-brachial pressure index, blood pressure, and heart rate were compared between the two groups. There were 87 women (mirabegron, n = 43; and solifenacin, n = 44) who completed 12-week treatment and underwent heart rate variability examination. Systolic blood pressure (median: − 4.5 to − 5.5 mmHg) and diastolic blood pressure (median: − 0.5 to − 3.5 mmHg) decreased after solifenacin treatment, and heart rate (median: + 2 bpm) increased after mirabegron treatment, despite of no between-group difference. In addition, posttreatment heart rate variability, cardio-ankle vascular index, and ankle-brachial pressure index did not differ compared with baseline; and there were no between-group differences. In conclusion, solifenacin might decrease blood pressure, and mirabegron might increase heart rate. Nonetheless, there were no significant impacts of 12-week mirabegron versus solifenacin treatment on autonomic function and arterial stiffness.

Abstract
Bladder dysfunction, which involves inadequacies of urine storage or emptying, increases with age. Conventional medications may have insufficient efficacy for patients with refractory lower urinary tract symptoms, and their concomitant adverse events (AEs) may be intolerable for the older adult population. For decades, the botulinum toxin type A (BoNT-A) injection has been an option for managing urine frequency, urge incontinence, and voiding dysfunction in the general population refractory to conventional management. This review focuses on studies of BoNT-A application in the management of bladder dysfunction in older adult patients aged ≥ 65 years. In this target population, intravesical BoNT-A injections provide similar efficacy in idiopathic overactive bladder to that in younger adults. Good clinical response has also been demonstrated in older adult patients presenting with storage dysfunction and with various concomitant underlying neurological diseases. However, caution must be taken for the AEs that occur after intravesical BoNT-A injection, including increased post-void residual urine, acute urine retention, and urinary tract infection. Most evidence shows that age is not a major determinant of AEs after adjusting for other factors. In contrast to its application in storage dysfunction, evidence for voiding dysfunction in older adults is scarce. In general, BoNT-A may be a reasonable option for older adult patients with refractory storage dysfunction because of its promising clinical response without significant systemic AEs. Overall, clinicians should be aware of the balance between the therapeutic efficacy of BoNT-A and local AEs in vulnerable members of this population.

Abstract
Background Real-world data from electronic health records (EHRs) represent a wealth of information for studying the benefits and risks of medical treatment. However, they are limited in scope and should be complemented by information from the patient perspective. Objective The aim of this study is to develop an innovative research infrastructure that combines information from EHRs with patient experiences reported in questionnaires to monitor the risks and benefits of medical treatment. Methods We focused on the treatment of overactive bladder (OAB) in general practice as a use case. To develop the Benefit, Risk, and Impact of Medication Monitor (BRIMM) infrastructure, we first performed a requirement analysis. BRIMM’s starting point is routinely recorded general practice EHR data that are sent to the Dutch Nivel Primary Care Database weekly. Patients with OAB were flagged weekly on the basis of diagnoses and prescriptions. They were invited subsequently for participation by their general practitioner (GP), via a trusted third party. Patients received a series of questionnaires on disease status, pharmacological and nonpharmacological treatments, adverse drug reactions, drug adherence, and quality of life. The questionnaires and a dedicated feedback portal were developed in collaboration with a patient association for pelvic-related diseases, Bekkenbodem4All. Participating patients and GPs received feedback. An expert meeting was organized to assess the strengths, weaknesses, opportunities, and threats of the new research infrastructure. Results The BRIMM infrastructure was developed and implemented. In the Nivel Primary Care Database, 2933 patients with OAB from 27 general practices were flagged. GPs selected 1636 (55.78%) patients who were eligible for the study, of whom 295 (18.0% of eligible patients) completed the first questionnaire. A total of 288 (97.6%) patients consented to the linkage of their questionnaire data with their EHR data. According to experts, the strengths of the infrastructure were the linkage of patient-reported outcomes with EHR data, comparison of pharmacological and nonpharmacological treatments, flexibility of the infrastructure, and low registration burden for GPs. Methodological weaknesses, such as susceptibility to bias, patient selection, and low participation rates among GPs and patients, were seen as weaknesses and threats. Opportunities represent usefulness for policy makers and health professionals, conditional approval of medication, data linkage to other data sources, and feedback to patients. Conclusions The BRIMM research infrastructure has the potential to assess the benefits and safety of (medical) treatment in real-life situations using a unique combination of EHRs and patient-reported outcomes. As patient involvement is an important aspect of the treatment process, generating knowledge from clinical and patient perspectives is valuable for health care providers, patients, and policy makers. The developed methodology can easily be applied to other treatments and health problems.

Abstract
PURPOSE OF REVIEW This review explores the subject of lower urinary tract symptoms (LUTS) in young men. RECENT FINDINGS Young men (aged 39 or younger) can be affected by a variety of conditions that can cause LUTS. Approximately half of young men report LUTS. Storage or "irritative" voiding symptoms are nearly twice as common as "obstructive" symptoms in young men. Infectious or inflammatory causes such as prostatitis are the most common cause of LUTS in this age group, while other etiologies include urethral strictures, primary bladder neck obstruction, as well as neurogenic and non-neurogenic bladder dysfunction. A thorough clinical evaluation is critical for determining the correct diagnosis and directing the appropriate treatment plan. Young men experience lower urinary tract symptoms at relatively high rates. Clinical treatments range from behavioral therapy to medications and/or surgical interventions. Ambulatory urodynamics and wearable sensors may provide more accurate and real-world diagnostic assessment of bladder dysfunction in this relatively under-studied group. More study is needed to characterize the disease burden and impact in this specific group of patients.

Abstract
INTRODUCTION Reductions in bothersome symptoms of overactive bladder (OAB) demonstrate improvement in clinical trials, but patient perception of meaningfulness of such improvement is lacking. In the 12-week phase 3 EMPOWUR trial, vibegron significantly reduced average daily number of micturitions, urgency episodes, and urge urinary incontinence (UUI) episodes vs placebo (P < 0.01 each). This analysis assessed meaningfulness of reductions in clinical endpoints observed in EMPOWUR using patient perception of improvement. METHODS An anchor-based approach using Patient Global Impression of Change (PGI-C) applied to phase 2 data allowed predefining phase 3 responder definitions. To confirm in phase 3, median change from baseline at week 12 in average daily number of micturitions, urgency episodes, and UUI episodes was generated for each PGI-C category and pooled across treatments. Based on predefined meaningful responder definitions, percentages of patients achieving ≥ 15% reduction in micturitions (post hoc), ≥ 50% reduction in urgency episodes (predefined), and ≥ 75% (predefined) and ≥ 90% (post hoc) reduction in UUI episodes were determined for patients receiving vibegron or placebo. RESULTS Across treatments, for micturitions, urgency episodes, and UUI episodes, median change from baseline to week 12 increased with greater subjective improvement based on PGI-C scores, and median reductions pooled across treatment groups were higher than the responder definitions that patients perceived as improved. Significantly more patients receiving vibegron vs placebo achieved ≥ 15% reduction in micturitions (56.3% vs 44.6%, respectively), ≥ 50% reduction in urgency episodes (39.5% vs 32.8%), ≥ 75% reduction in UUI episodes (49.3% vs 32.8%), and ≥ 90% reduction in UUI episodes (35.2% vs 23.5%) at week 12 (P < 0.05 each). CONCLUSION Significantly more patients treated with vibegron vs placebo in EMPOWUR achieved meaningful reductions in micturitions, urgency episodes, and UUI episodes that were associated with patient-perceived improvement. Results of these analyses support the meaningfulness of reductions in clinical endpoints observed in the 12-week EMPOWUR trial.

Abstract
Medical treatment of overactive bladder (OAB) includes antimuscarinic agents, beta-3 adrenoceptor agonist (mirabegron), or combination with both drugs. Recently, a meta-analysis reported the integrated clinical trial data from 10 phase 2–4, double-blind, 12-week mirabegron monotherapy studies. The results confirmed that mirabegron is as effective as the previously used antimuscarinic agent to treat OAB. The treatment-emergent adverse events were similar across subgroups. This article comments on this largest integrated clinical trial data analysis, and reviews the recently published literature and tries to reveal how to choose the appropriate medication for OAB. For OAB patients, starting from antimuscarinic agent is feasible. However, if the patients have risk of cognitive dysfunction, a history of constipation, dry mouth, and urinary retention, starting with mirabegron 50 mg might be more safe and appropriate. In the elderly patients with low detrusor contractility, with central nervous system lesion, and men with benign prostatic hyperplasia, starting from 25 mg mirabegron is recommended. If the treatment result is not satisfactory to the 25 mg mirabegron, increase dose to 50 mg mirabegron is appropriate. In patients who have failed from the first OAB medication either with antimuscarinics or mirabegron 50 mg, the exchange of the OAB medication to each other should be tried first. If the treatment result is still not satisfactory, a combination of antimuscarinics and mirabegron is recommended.

Abstract
OBJECTIVE To evaluate the additional effects of mirabegron to alpha-1 adrenergic antagonist on lower urinary tract symptoms of patients who underwent 125I-brachytherapy for prostate cancer. PATIENTS AND METHODS Patients who underwent 125I-brachytherapy for prostate cancer (cT1-cT3aN0M0) in a single institute between September 2016 and October 2018 were enrolled in the randomized, non-placebo, open-labeled, paralleled study. Patients were randomly distributed (1:1) to combination group (tamsulosin (0.2 mg/day) plus mirabegron (50 mg/day)) or tamsulosin-alone group after 125I -brachytherapy by envelope method. The primary endpoint was the change from baseline in mean voided volume per micturition 3 months after 125I brachytherapy. The secondary endpoints included the changes from baseline of International Prostate Symptom Score, Overactive Bladder Symptom Score, and Expanded Prostate Cancer Index Composite scores and 24 hours urinary frequency after 3 months after 125I brachytherapy. RESULTS The mean changes in volume voided per micturition in the combination (n = 108) and tamsulosin-alone (n = 110) groups were -62.5 (standard deviation, ±53.8) and -68.0 (standard deviation, ±52.7), respectively (P = .17). The change in Overactive Bladder Symptom Score in combination group (P = .02) was more moderate than in tamsulosin-alone group; and 24 hour urinary frequency in combination group was lower (P = .03) than in tamsulosin-alone group. Retention rates within 3 months after 125I-brachytherapy in the mirabegron and tamsulosin-alone groups were 7.3% (9/122) and 6.0% (7/118), respectively (P = .80). CONCLUSION Tamsulosin and mirabegron combination therapy after 125I-brachytherapy did not improve voided volume per micturition compared to tamsulosin-only treatment. However, it could improve frequent urination and overactive bladder symptoms.

Abstract
Purpose To determine the effect of the new β3-agonist (mirabegron), which is used for overactive bladder (OAB) treatment, on central retinal thickness (CRT) and choroidal vascularity. Material and Methods The 26 eyes of 26 cases using 50 mg tablet mirabegron once per day for OAB were included in this prospective case control study. The CRT, choroidal thickness (ChT), and choroidal vascularity were measured at baseline, week 1 (W1), month 1 (M1), month 2 (M2), and month 3 (M3). Subfoveal ChT measurement included the total subfoveal choroidal thickness (SFCT), and the small and large choroidal vessel layer (SCVL and LCVL) thickness. The total choroidal area (TCA), lumen area (LA), stromal area (SA), stroma/lumen ratio, and choroidal vascularity index (CVI) were measured with the Image-J software. Results The largest SFCT increase compared to baseline was at M1 (26.8 ± 40.8 µm, P = 0.001). The subfoveal SCVL thickness showed a significant decrease at M2 and M3 (−6.0 ± 8.9 µm, P = 0.002; −7.8 ± 13.4 µm, P = 0.046, respectively). LCVL thickness showed a significant increase at W1, M1, and M2, with the largest at M1. CVI showed a significant increase at M1, M2, and M3 (P < 0.05 for all). The TCA, LA, and SA showed a significant increasing trend at all follow-up periods. LA/SA decreased at W1 because of stromal expansion but increased at M3 with more prominent vascular dilatation. CRT values showed no significant change. Conclusions Mirabegron had a significant effect on choroidal thickness. Choroidal vascular response is in the form of narrowing in the choriocapillaris and enlargement in the Haller's layer.

Abstract
Introduction: Bladder and urinary sphincter malfunctioning that results from some change in the central and/or peripheral nervous system is defined as neurogenic bladder. The urinary tract symptoms that can be related to its filling, emptying, or both have a significant impact on the quality of life of individuals. The present review was based on the document prepared for the public health system in Brazil as a treatment guidelines proposal. Material and Methods: Survey questions were structured as per PICO (Population, Intervention, Control, and Outcome). Search strategies were defined and performed in the MEDLINE/Pubmed, Embase, Epistemonikos and Google Scholar databases. The selection of articles followed the evidence hierarchy concept; evidence body was identified, and the quantitative study data were extracted. The quality of evidence and grade of recommendation were qualitatively assessed according to GRADE (Grading of Recommendations, Assessment, Development and Evaluations). Results: A total of 2.707 articles were identified, with 49 of them being selected to compose the basis for this review. Neurogenic bladder treatments were classified according to their focus on filling or emptying symptoms and sub- classified in pharmacological and surgical treatments. Conclusion: Treatment guidelines are important tools for the public health system to promote the best practice when treating neurogenic bladder patients.

Abstract
PURPOSE The purpose of this study is to investigate the efficacy and safety of mirabegron versus solifenacin in the treatment of newly diagnosed overactive bladder (OAB) in children. METHODS We conducted a prospective randomized controlled study on pediatric patients with newly diagnosed OAB. Patients were randomized into 3 groups: mirabegron (50 mg once daily) in group I, solifenacin (5 mg) in group II, and placebo in group III. Before starting our treatment and at the end of the 3 months course, we obtained a 3-day voiding diary. This diary included incontinence episode per day, mean voided volume per micturition, mean number of micturition per day, and post-void residual urine. Moreover, the parents/patients were asked to rate symptom relief, and the adverse events were recorded throughout the study period. RESULTS A total of 190 patients aged from 5 to 14 years completed this study. At the end of this trial, both groups I and II showed significant improvement versus placebo regarding our efficacy parameters with no significant difference between group I and II. The overall success rate based on assessment of symptom relief was significantly higher in the treated groups (87.5% in I and 90.2% in II) versus placebo (55.8%). Dry mouth was reported in 2.8, 10, and 0% and constipation in 2.8, 11.4, and 1.4% in group I, II, and III, respectively, without statistically significant difference between group I and placebo. However, there was a significant difference between group II and placebo regarding these side effects. CONCLUSION Both mirabegron and solifenacin have comparable efficacy regarding the control of OAB symptoms in the newly diagnosed children, but mirabegrone seems to have less side effects.

Abstract
Objectives This analysis from the PERSPECTIVE (a Prospective, Non‐interventional Registry Study of Patients Initiating a Course of Drug Therapy for Overactive Bladder) study evaluated treatment persistence with mirabegron or antimuscarinics over a 12‐month period. Methods Participants were adults diagnosed with overactive bladder (OAB) by their health care provider (HCP), who were initiating mirabegron or antimuscarinic treatment. The HCP made all treatment decisions, and patients were followed for 12 months with no mandatory scheduled visits. Information requests were sent to patients at baseline and months 1, 3, 6, and 12. Patients were nonpersistent if they switched, discontinued, or added OAB medications/therapies to their initial treatment. Reasons for discontinuation and switching patterns were investigated. Results Overall, 1514 patients were included (613 mirabegron and 901 antimuscarinic initiators). Persistence rates decreased steadily over time in both groups. A low proportion of patients added or switched medication at each time point. Unadjusted Kaplan‐Meier analysis showed similar persistence rates for both groups. When the data were adjusted for patient characteristics (age, sex, and OAB treatment status), mirabegron initiators had higher persistence rates. No significant differences were noted in unadjusted median time to end of persistence. However, end of treatment persistence by any cause was longer with mirabegron (median: 9.5 vs 6.7 months for antimuscarinics). HCPs stated that the most common reasons for nonpersistence were no symptomatic improvement and side effect aversion. Conclusions Treatment persistence was longer for mirabegron compared with antimuscarinic initiators after controlling for patient characteristics. End of treatment persistence by any cause was also longer with mirabegron.

Abstract
AIM Overactive bladder (OAB) is a common and troublesome condition that can significantly impair quality of life. This review aims to educate providers of obstetrics and gynecology services about available therapies for OAB and what to expect following treatment. METHODS Here, we review published data from studies that have evaluated available treatments for OAB. Relevant articles published over the past 2 decades, including large multicenter trials, were identified through a literature search using PubMed.gov, and the references in those articles were also manually searched to find additional articles. Treatment guidelines and product labels were also reviewed. RESULTS Behavioral therapy is recommended as a first choice for OAB management; pharmacologic treatment (anticholinergics, β3 -adrenoceptor agonists) as second-line treatment; and onabotulinumtoxinA, peripheral tibial nerve stimulation, and sacral nerve stimulation as third-line therapy for patients refractory or intolerant to first- and second-line treatments. A stepwise approach to treatment through first-, second-, and third-line therapies is recommended, recognizing this may not be appropriate for all patients. CONCLUSIONS To optimize symptom control and set realistic expectations, patients should be carefully monitored and counseled appropriately on available treatment options.

Abstract
Objective This study retrospectively investigated the influence of urodynamic parameters and patient characteristics on success rates among patients with overactive bladder (OAB) and urodynamic detrusor overactivity (DO). Materials and Methods Consecutive patients with OAB and urodynamic DO initially received solifenacin, mirabegron, or combination of both for 1-3 months. If failed, patients were switched to another OAB medication subtype or provided additional OAB medication for a total of 6 months. A successful treatment was defined as an improvement in urgency severity and a global response assessment of ≥1. Success rates after initial or modulated OAB medication were analyzed based on patient and urodynamic characteristics. Results A total of 453 patients were enrolled, among whom 144, 255, and 54 received solifenacin, mirabegron, and combined medications, respectively. Among the patients, 259 (57.2%) had OAB dry and 194 (42.8%) had OAB wet. Patients receiving mirabegron alone had a significantly higher initial medication success rate compared to that of others. Patients with a phasic DO (50.7%), bladder outlet obstruction (BOO, 52.5%), and no central nervous system (CNS) lesions (47.5%) exhibited higher success rates than those with a terminal DO (42.0%), no BOO (42.7%), and CNS lesions (31.6%), respectively. After switching or modulating the initial OAB medication following treatment failure, 115 (62.2%) of 185 patients still showed improvement in OAB symptoms, with an overall success rate of 70.2% after 6 months of treatment. Conclusion Initial solifenacin or mirabegron treatment had a success rate of around 50%. In general, patients with a phasic DO, urodynamic BOO, and no CNS lesions have higher success rates than those with a terminal DO, no BOO, and CNS lesions, respectively. Success rates can further be improved by switching or modulating OAB medication.

Abstract
CONTEXT The role of overactive bladder (OAB) treatment in women beyond antimuscarinics has been evaluated extensively. Beta-3 agonists, botulinum toxin-A (BTX-A), and nerve stimulation are indicated in these patients. However, data on male patients in this clinical scenario are scarce. OBJECTIVE The aim of this systematic review was to evaluate the evidence on treatment options beyond antimuscarinics in men with OAB. EVIDENCE ACQUISITION A search of PubMed, EMBASE, Scopus, Web of science, Cochrane Central Register of Controlled Trials, and Cochrane Central Database of Systematic Reviews databases was performed for relevant articles published between January 2000 and October 2020, using the following Medical Subject Headings: "male/man," "LUTS," "overactive bladder," "storage symptoms," "urgency," "nocturia," "incontinence," "beta-3 agonist," "PDE-5 inhibitors," "botulinum toxin," "sacral nerve stimulation/neurostimulation," "percutaneous/transcutaneous tibial nerve stimulation," "PTENS," and "combination therapy." Evidence acquisition was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. PROSPERO registration number is CRD42020201223. EVIDENCE SYNTHESIS Overall, 24 studies were retrieved. In male OAB, mirabegron (MIRA) is the most intensively investigated pharmacological option. A pooled analysis of five randomized clinical trials (RCTs), including 1187 patients, concluded that MIRA 50 mg was associated with a greater reduction in frequency versus placebo (-0.37, 95% confidence interval [CI]: -0.74, -0.01, p < 0.05). A pooled analysis of three RCTs, including 1317 male patients, has also shown that the addition of MIRA 50 mg in men receiving the α1-blocker tamsulosin improved the mean number of micturitions per day (-0.27, 95% CI: -0.46 to -0.09, p < 0.05), urgency episodes (-0.50, 95% CI: -0.77 to -0.22, p < 0.05), total OAB symptom score (-0.66, 95% CI: -1.00 to -0.38, p < 0.05), and mean volume voided (+10.76 ml, 95% CI: 4.87-16.64, p < 0.05). MIRA treatment is well tolerated in men. Other pharmacological treatment options, such as phosphodiesterase-5 (PDE-5) inhibitors, should be considered investigational. BTX-A seems to be effective as third-line treatment in male OAB patients. A higher rate of intermittent self-catheterization (5-42%) is observed in male than in female patients. Data on nerve stimulation are scarce. CONCLUSIONS MIRA has the most robust data in terms of safety and efficacy in this patient population. Preliminary data in men suggest that BTX-A is indicated as an interventional treatment. Evidence for PDE-5 inhibitors and nerve stimulation is too limited to provide recommendations. Future studies in this population should aim to better define the best treatment sequence and to identify predictors for treatment response and failure, to determine a therapeutic approach tailored to patients' characteristics. PATIENT SUMMARY Overactive bladder is highly prevalent in men. Mirabegron 50 mg is the treatment option supported by the highest level of evidence when antimuscarinics failed. Botulinum toxin A injections seems to be an effective treatment as interventional option. Roles of nerve stimulation and phosphodiesterase inhibitors in male OAB patients are still to be defined.

Abstract
This review discusses the available evidence in the current evaluation and treatment of nocturia in frail older adults. No evidence specifically evaluates the use of behavioral interventions in the treatment of the frail older adult with nocturia, but their use is supported in other cohorts. Behavioral modifications and optimal management of comorbidities remain the first-line treatment for all age groups and should be emphasized in the frail due to their favorable safety profile. No studies specific to the frail older adult support the use of pharmacotherapy. Some evidence exists for the efficacy of several agents in the older adult; however, this is difficult to extrapolate to the frail, and safety concerns abound. Desmopressin may be effective in the older adult, but a high risk of hyponatremia raises concerns for its safety, and therefore it is not recommended in the frail. α-Antagonists may have limited efficacy in men with known benign prostatic hyperplasia (BPH); they are relatively well tolerated, although the risk of orthostatic hypotension in the frail should be considered. β3-agonist trials suggest limited clinical utility. Antimuscarinics are not found to be useful in this cohort and are contraindicated in the frail older adult given the ability of antimuscarinics to cause cognitive impairment, delirium, and falls. No data examine the use of nonsteroidal anti-inflammatory drugs (NSAIDs) in the frail older adult. Additionally, the American Geriatrics Society Beers Criteria recommends against the use of muscarinics in those over the age of 75 years and therefore their use is not supported.

Abstract
Background In older patients with overactive bladder (OAB), mirabegron, a β3-adrenoreceptor agonist, represents an alternative treatment that may have a favorable risk–benefit profile. Objectives Our objective was to further examine the safety and tolerability of mirabegron versus placebo treatment in patients aged ≥ 65 years with OAB-wet. Methods We conducted a 12-week, double-blind, randomized, placebo-controlled phase IV study to compare mirabegron with placebo. Community-dwelling patients aged ≥ 65 years with OAB-wet (one or more incontinence episode and three or more urgency episodes, and an average of eight or more micturitions/24 h over a 3-day diary) were randomized to receive placebo or mirabegron 25 mg/day (optional dose escalation to 50 mg/day at week 4 or 8). Safety analyses were performed for adverse events (AEs) and vital signs on all randomized patients who received one or more dose of study drug. Results Treatment-emergent AEs (TEAEs), the majority mild or moderate in severity, were reported in 39.4% of placebo patients and 44.2 and 49.8% of those who received mirabegron 25 mg or 50 mg, respectively. The most common TEAEs in mirabegron-treated patients were urinary tract infection, headache, and diarrhea. The incidence of TEAEs was slightly higher in mirabegron patients aged ≥ 75 years than in those aged < 75 years. There were no clinically meaningful differences in changes in vital signs from baseline to end of treatment for any treatment group, and no differences were observed between mirabegron and placebo treatment groups. TEAEs tended to occur early post exposure and were not dose related. Conclusions Mirabegron treatment was well-tolerated in older adults with OAB-wet. Safety and tolerability were consistent with the known mirabegron safety profile. Trial Registration This study is registered at ClinicalTrials.gov: NCT02216214.

Abstract
PURPOSE OF THE REVIEW This paper discusses the recent evidence supporting beta 3 adrenergic agonists as the preferred pharmacological management of overactive bladder syndrome. RECENT FINDINGS Mirabegron has a similar efficacy profile to first-line antimuscarinics with favorable adverse effects profile. Treatment of OAB with beta-3 adrenergic agonist should be favored in patients at higher risk of anticholinergic adverse events. The efficacy and tolerability of beta-3 adrenergic agonists are consistently reported in older OAB patients, whether used alone or with other antimuscarinics. Mirabegron is cost-effective in treating OAB unless the symptoms were severe or refractory. Combination therapy of mirabegron and other pharmacotherapy has proven to be efficient in controlling OAB symptoms without inducing serious add-on adverse effects. While beta-3 adrenergic agonists bear favorable advantages in OAB treatment, physicians should perform a thorough and careful pre-treatment planning to optimize treatment benefits and adherence.

Abstract
Objectives To investigate the cardiovascular safety of mirabegron add‐on treatment to tamsulosin in male patients with residual overactive bladder symptoms. Methods This was a post hoc analysis of MATCH, the first double‐blind, placebo‐controlled study comparing mirabegron and placebo as add‐on therapy to tamsulosin for treatment of overactive bladder in men with lower urinary tract symptoms. The analysis focused on treatment‐emergent adverse events relating to the cardiovascular system or blood pressure, and changes in vital signs during 12 weeks of follow‐up. Results Cardiovascular‐related treatment‐emergent adverse events were reported by 6/566 patients, although only one serious treatment‐emergent adverse event was related to treatment (unstable angina in the tamsulosin + placebo group). Hypertension (two patients) and increased blood pressure (one patient) were reported in the tamsulosin + placebo group, but there were no blood pressure‐related treatment‐emergent adverse events among tamsulosin + mirabegron patients. There were no clinically meaningful changes from baseline in blood pressure, and changes in pulse rate were small (+1.2 bpm in the tamsulosin + mirabegron group). Increased pulse rate was more frequent with tamsulosin + mirabegron than with tamsulosin + placebo in older patients, although within the normal range. Conclusions Cardiovascular‐related adverse events were uncommon in both treatment groups. Mirabegron is a well‐tolerated add‐on therapy to tamsulosin in Japanese and Korean males with residual overactive bladder symptoms.

Abstract
Lower urinary tract symptoms, including urgency, urgency incontinence, frequency, and nocturia, are highly prevalent in older adults and are associated with significant morbidity and impairment in quality of life. When conservative measures such as bladder training fail to improve symptoms, pharmacological management is recommended by national and international guidelines. Mirabegron, an agonist of the β3 adrenergic receptor, demonstrates similar efficacy to the anticholinergic drugs without the risk of anticholinergic effects, but experience and evidence in the very elderly population are limited. This narrative review examines the current evidence base for mirabegron in very elderly adults.

Abstract
Objective: The objective of this study was to evaluate the efficacy of mirabegron 25 mg daily in patients with nocturia-predominant hypersensitive bladder (HSB). Materials and Methods: This study prospectively investigated 219 consecutive patients with nocturia-predominant HSB and treated with mirabegron 25 mg daily from July 2015 to 2016. Patient with nocturia episode decreased by ≥1/night after treatment was considered successful. The subjective symptom score, such as International Prostate Symptom Score (IPSS), Quality of life index, Overactive Bladder Symptom Score (OABSS), Urgency Severity Scale, patient perception of bladder condition (PPBC), and nocturia episodes per night, was assessed before and 1 month after mirabegron treatment and between successful and failed groups. Results: A total of 219 patients, including 51 women and 168 men, were enrolled. The mean age of the population was 72.3 ± 11.0 years. Totally, 58 (26.5%) of the patients had improvement in nocturia at 1 month after treatment. Among them, 14 (27.5%) women and 44 (26.2%) men had improvement in nocturia episodes after treatment (P = 0.858). Compared the clinical data between successful and failed group, the baseline symptom scores were more severe in successful group, including IPSS-storage subscore (4.84 ± 2.09 vs. 4.11 ± 2.19, P = 0.031), OABSS (3.21 ± 0.67 vs. 2.91 ± 1.00, P = 0.037), and nocturia episodes (3.81 ± 0.95 vs. 3.095 ± 1.32, P = 0.000). Multivariate analysis revealed only a higher nocturia episodes (P = 0.046) predict a successful treatment result. Mirabegron 25 mg daily significantly improved PPBC score along the 3 months' follow-up (P < 0.05), and postvoid residual volume did not increase after mirabegron treatment in overall patients. Conclusions: Mirabegron 25 mg daily treatment showed a limited therapeutic effect on nocturia-predominant HSB patients. The patients with higher OAB symptoms predict a successful result.

Abstract
Objective This analysis was conducted to investigate the cardiovascular (CV) safety outcomes from the MILAI II study. MILAI II was conducted to evaluate the long‐term safety and efficacy of antimuscarinic add‐on therapy to mirabegron over 52 weeks in patients with overactive bladder (OAB) symptoms. Methods MILAI II consisted of a 2‐week screening period (patients received mirabegron 50 mg once daily) plus a 52‐week treatment period (patients were randomized to receive a combination of mirabegron 50 mg/d plus solifenacin 5 mg/d, propiverine 20 mg/d, imidafenacin 0.2 mg/d, or tolterodine 4 mg/d). CV safety was assessed using treatment‐emergent adverse events (TEAEs), vital signs, and 12‐lead electrocardiograms (ECGs). Vital signs and ECG data were evaluated for each patient using worst post‐baseline values reported. Results Of 647 patients, 570 (88.1%) were female with a mean age of 65 years. CV history at baseline and CV‐related concomitant medication use throughout the study were balanced between groups. The incidences of overall and drug‐related CV TEAEs were ≤8.1% and ≤6.2%, respectively, for all groups. The most common TEAEs were ECG T wave amplitude decreased, ECG QT prolonged, and ventricular extrasystoles. Overall, 36 TEAEs of interest related to the CV system that were possibly/probably related to treatment were reported with similar incidences for each group. For the worst post‐baseline vital signs and ECGs, no relationships were noted in terms of either timing or treatment group. Conclusion A favorable CV safety profile was observed following long‐term combination treatment with mirabegron and an antimuscarinic in patients with OAB symptoms.

Abstract
Overactive bladder syndrome (OAB) negatively affects the quality of life of patients and their interactions with society. Treatment of OAB starts with behavioral modification and then pharmacotherapy using monotherapy with either antimuscarinics or β3 agonists. The third-line more invasive approaches are the next treatment option currently recommended. Both antimuscarinic agents and β3 agonists work through a different molecular pathway. This brings up the potential of having an additive effect when using a combination treatment for patients with OAB. Currently, the potential for using combination therapy to treat OAB in patients who had no improvement with a monotherapy approach before we attempt a more invasive approach is being explored. Several studies have shown the benefits of combination therapy which will be an additional option to the tools to treat OAB.

Abstract
Purpose: The persistence of treatment with mirabegron and the reasons for withdrawal from the treatment among treatment-naïve Japanese female patients with overactive bladder (OAB) were prospectively investigated for 3 years in the real-world clinical setting. Materials and Methods: A total of 62 treatment-native Japanese female patients clinically diagnosed with OAB were treated with mirabegron and prospectively followed for 3 years. The persistence rate was estimated using the Kaplan-Meier method. If mirabegron had to be terminated or a patient did not come to the hospital to receive a prescription, the reasons for withdrawal from treatment were determined. Results: The 6-month, 1-year, 2-year, and 3-year persistence rates were 51.6%, 38.7%, 32.3%, and 25.8%, respectively. The most frequent reasons for withdrawal from treatment with mirabegron were symptom resolution (38.7%), deterioration of comorbidity unrelated to OAB (12.9%), lack of efficacy (8.1%), and adverse events (4.8%). Conclusions: The persistence rate of treatment with mirabegron among treatment-naïve Japanese female patients with OAB is low for 3 years in the real-world clinical setting. Many patients discontinue the treatment for various reasons, the most frequent of which is symptom resolution. These findings provide important considerations for clinicians whose patients are continuing medication for OAB.

Abstract
OBJECTIVE To review the literature regarding the efficacy and safety of mirabegron for the treatment of overactive bladder (OAB). DATA SOURCES A literature search was performed using MEDLINE (PubMed) prior to December 31, 2013, using the terms "mirabegron" and "randomized-controlled trial." STUDY SELECTION/DATA EXTRACTION All published, double-blind, randomized-controlled trials assessing mirabegron were included. Articles were reviewed and included if mirabegron was used as monotherapy and if the primary outcome analyzed drug efficacy. DATA SYNTHESIS The efficacy of mirabegron for the treatment of OAB has been demonstrated in the selected five randomized, placebo-controlled trials. The majority of these trials lasted 12 weeks and compared various doses of mirabegron with placebo and/or tolterodine extended-release (ER). Primary efficacy outcomes for the trials included mean number of micturitions per 24 hours and mean number of incontinence episodes per 24 hours. Included trials showed statistically significant reductions in both efficacy outcomes for various doses of mirabegron when compared with placebo. CONCLUSION Based on the trials reviewed, mirabegron has been efficacious in reducing mean number of micturitions and incontinence episodes per 24 hours, as well as in improving other secondary outcomes such as OAB symptoms and quality-of-life measures. Common adverse drug events seen with mirabegron include: hypertension, nasopharyngitis, urinary tract infections, headache, constipation, upper respiratory tract infection, arthralgia, diarrhea, tachycardia, abdominal pain, and fatigue. Given the efficacy and safety data currently available, mirabegron represents a reasonable alternative to antimuscarinics for patients with OAB. Future studies are needed to determine the utility of mirabegron for OAB in a variety of demographics.

Abstract
OBJECTIVE To compare the efficacy and safety of mirabegron and onabotulinumtoxinA in the management of treatment-experienced patients with overactive bladder. METHODS The network meta-analysis was based on evidence from a systematic literature review of randomized controlled trials and a post-hoc analysis of treatment-experienced subpopulations from mirabegron studies. RESULTS Nineteen trials described in 21 publications were included. CONCLUSION Overall, compared to mirabegron, there was some evidence that onabotulinumtoxinA was associated with improved outcomes, including reductions in the number of micturitions in a 24-hour period, and the number of incontinence episodes. However, mirabegron was associated with a lower risk of urinary tract infections compared with onabotulinumtoxinA.

Abstract
This was the first study to construct a physiologically-based pharmacokinetic (PBPK) model for mirabegron which incorporates the overall elimination pathways of metabolism by cytochrome P450 (CYP) 3A4, uridine 5'-diphosphate-glucuronosyltransferase (UGT) 2B7, and butyrylcholinesterase (BChE) and renal excretion. The objective was to assess the risk of drug-drug interactions (DDIs) by estimating the contribution of each elimination pathway and simulating the magnitude of the DDIs with UGT2B7 inhibitors. A PBPK model for mirabegron was constructed to reproduce the plasma concentration-time curves from a phase 1 study and the magnitude of the DDI with ketoconazole taking into account the overall elimination pathways. The PBPK model was subsequently verified using data from other DDI studies. The constructed PBPK model estimated the contribution for each elimination pathway: 44% and 29% for CYP3A4 and UGT2B7 in the liver, 1.6% for UGT2B7 in the kidney, 3.2% for BChE in plasma, and 22% for renal excretion. Co-administration of probenecid (an UGT2B7 inhibitor) or fluconazole (an UGT2B7 and CYP3A4 inhibitor) was predicted to increase area under the curve for mirabegron to 115% or 174%, respectively. In conclusion, PBPK modeling and simulation revealed a low DDI risk for mirabegron following co-administration with BChE or UGT2B7 inhibitors.

Abstract
Overactive bladder (OAB), the syndrome characterized by urgency, with or without urgency incontinence, usually with frequency and nocturia, in the absence of infection or other pathology, is a common, distressing and often debilitating condition with a high prevalence in the general population. For many years, the only available pharmacological treatment for OAB were the antimuscarinic agents. More recently, mirabegron, a selective agonist of the β3 adrenergic receptor, has become available. In this article we review the current evidence and experience of its use.

Abstract
Background Persistence on-treatment with antimuscarinics in patients with overactive bladder (OAB) is reported to be sub-optimal. This retrospective, longitudinal, observational cohort study assessed treatment persistence with β3-adrenoceptor agonists (i.e. mirabegron) and antimuscarinics, both classes of OAB pharmacotherapy, in patients with OAB in Spain. Methods Adults who received mirabegron or an antimuscarinic in routine clinical practice (1 June–31 October 2014), were identified from anonymised prescription data within the Spanish Cegedim Electronic Medical Records database. The primary endpoint, treatment persistence (time to treatment discontinuation [TTD] and the proportion of patients remaining on-treatment after 12 months), was unadjusted for potential confounders. Multivariate Cox regression models of persistence, adjusted for baseline characteristics, were used to compare differences in treatment groups. Adjusted subgroup analyses (target OAB drug, age, treatment status and sex) and sensitivity analyses (extending the time used to define treatment discontinuation from 30 days [base-case] to 45, 60 or 90 days without prescription renewal) were also performed. Results Overall, 1798 patients received mirabegron (N = 1169) or an antimuscarinic (N = 629); the mean age was 66.42 years. Median TTD was longer for mirabegron versus antimuscarinics (90 vs 56 days) and a higher proportion of patients who received mirabegron were persistent after 12 months (20.2% vs 10.2%); multivariate analyses indicated significantly greater persistence with mirabegron versus antimuscarinics (hazard ratio [HR]: 1.52; 95% confidence interval [CI]: 1.37–1.70; p < 0.001). Significant differences were also observed in subgroup analyses of mirabegron versus individual antimuscarinics (median TTD: 90 vs [range] 28–60 days; HR range: 1.21–2.17; p ≤ 0.013) and in all other subgroups assessed (p < 0.001). Sensitivity analysis showed that the median TTD for mirabegron increased by up to 31 days, and was significantly longer versus antimuscarinics across all adjusted periods (HR range: 1.43–1.53; all p < 0.001). Conclusions Patients with OAB in Spain who received mirabegron experienced longer persistence on-treatment than those who received antimuscarinics and the proportion of patients persistent on-treatment at 12 months with mirabegron was two-times higher versus antimuscarinics. These data may provide strategic insights for clinicians and policy makers involved in the management of OAB.

Abstract
Urgency is the prevalent and most bothersome symptom of overactive bladder (OAB) and the treatment of urgency is the primary objective in the management of OAB. Urgency has a major impact on other symptoms of OAB and culminates in an increased frequency of micturition and reduced volume voided, which may contribute to shorter intervals between the need to void. Antimuscarinic agents and mirabegron, a β3-adrenoceptor agonist, constitute the main oral pharmacotherapeutic options for the treatment of urgency and other OAB symptoms. The reduction of urgency and other OAB symptoms significantly improve health-related quality of life. This review will explore the distinct mechanisms of action and effects of antimuscarinic agents and mirabegron, in relation to their effect on the pathophysiology of urgency. The review will also provide an overview of the various validated measurements of urgency and the numerous clinical trials regarding antimuscarinic agent monotherapy, mirabegron monotherapy, or combination treatment with mirabegron added on to the antimuscarinic agent solifenacin. A narrative review of the literature relating to pathophysiology of urgency, the validated measurements of urgency, and clinical trials relating to the pharmacological treatment of urgency. Antimuscarinic agent monotherapy, mirabegron monotherapy, or combination treatment with mirabegron added on to the antimuscarinic agent solifenacin statistically significantly reduce the symptoms of urgency compared with placebo. Combination therapy with mirabegron added on to solifenacin also statistically significantly reduces the symptoms of severe urgency compared with antimuscarinic agent monotherapy. A critique of the clinical benefits of combination therapy is also provided. Combination therapy provides an alternative treatment in patients with OAB that includes urgency who respond poorly to first-line monotherapy and who may otherwise often move on to more invasive treatments.
