Effect of beta3-adrenoceptor Agonist on Patients With Overactive Bladder and as a Urinary Biomarker

Conditions
Detrusor Overactivity
Overactive Bladder Syndrome
Interventions
Registration Number
NCT04693897
Lead Sponsor
Chang Gung Memorial Hospital
Brief Summary

About one to two million women in Taiwan suffers from overactive bladder (OAB). The most commonly used anti-muscarinic drugs have a high rate of side effects. While beta-3 adrenoceptor agonist, Mirabegron, has far fewer side effects, there are no consensus on whether it can be used as first-line treatment. The investigator's preliminary study showed that the concentration of beta-3 adrenoceptor in the urine of OAB patients is higher than that in the normal control group, so comparing urinary beta-3 adrenoceptor concentration of OAB patients before and after treatment may be used as a biomarker of therapeutic effectiveness. The results of this study will be of great help in understanding the effectiveness of Mirabegron and formulating OAB treatment plans.

GroupInterventionDescription
Overactive bladder with MirabegronMirabegron 50 MG100 patients with overactive bladder syndrome, diagnosed according to 2002 ICS diagnosis will undergo 12 weeks of Mirabegron 50mg once daily use. Evaluation include questionnaire survey and urine beta-3 adrenoceptor concentration.
Overactive bladder with SolifenacinSolifenacin Succinate 5 MG100 patients with overactive bladder syndrome, diagnosed according to 2002 ICS diagnosis will undergo 12 weeks of Solifenacin 5mg once daily use. Evaluation include questionnaire survey and urine beta-3 adrenoceptor concentration.
Primary Outcome Measures
NameTimeMethod
Change in participant's urinary beta-3 adrenoreceptor from baseline to 12 weeks after treatment12 weeks

Concentrations of urinary beta-3 adrenoceptor levels will be analyzed for 1)before and after treatment of patients with overactive bladder syndrome treated with Mirabegron; 2)before and after treatment patients with overactive bladder syndrome treated with Solifenacin; 3)patients with urinary tract infection, and 4)control (subjects without lower urinary tract symptoms).

Secondary Outcome Measures
NameTimeMethod
Effect on the participant's life after treatment with Mirabegron and Solifenacin 6 months after treatment.6 months

Individual participant's change score on Short Form Health Survey (SF-12) will be compared between participants treated with Mirabegron and Solifenacin 6 months after treatment. SF-12 is a self-reported outcome measure assessing the impact of health on an individual's everyday life. The score is converted to a range of 0 to 100, with high the score indicating a better quality of life.

Effect of treatment with Mirabegron in patients with overactive bladder with or without detrusor overactivity after 12 weeks of treatment12 weeks

Individual participant's change score on Overactive Bladder Symptom Score (OABSS) will be compared between participants treated with Mirabegron with and without detrusor overactivity after 12 weeks of treatment. The OABSS is a validated symptom questionnaire that sums the score of four symptoms (daytime frequency, nighttime frequency, urgency, and urgency incontinence). The total score ranges from 0 to 15, with higher the number, the greater the symptoms are.

Change in impact on the participant's life after treatment with Mirabegron with overactive bladder with or without detrusor overactivity after 12 weeks of treatment.12 weeks

Individual participant's change score on the Overactive Bladder Questionnaire short-form (OAB-q SF) will be compared between participants treated with Mirabegron with and without detrusor overactivity after 12 weeks of treatment. The OAB-q SF assess the impact of OAB symptoms on the patient's life, and consists of symptom-bother and health-related quality of life. The subscales are summed and transformed into scores ranging from 0 to 100; a high symptom-bother score indicates greater symptom severity and a high health-related quality of life scale score indicates higher quality of life.

The participant's subjective measurement of treatment outcome with Mirabegron with overactive bladder with or without detrusor overactivity after 12 weeks of treatment.12 weeks

Individual participant's change score on Global Response Assessment Scale (GRAS) will be compared between participants treated with Mirabegron with and without detrusor overactivity after 12 weeks of treatment. GRAS is a subjective outcome measurement to asses the participant's perception of treatment success. The score is scaled from 0 to 100%, with greater the percentage, the greater improvement of symptoms after treatment is perceived.
