Sequencing and Combination of Mirabegron and TTNS in Overactive Bladder Syndrome: a Multicenter, Randomized, Open-label, Crossover Trial

27 de dezembro de 2021 atualizado por: Taipei Veterans General Hospital, Taiwan

Sequencing and Combination of Mirabegron and Transcutaneous Tibial Nerve Stimulation (TTNS) in Overactive Bladder Syndrome: a Multicenter, Randomized, Open-label, Crossover Trial

Research question:

A wealth of existing research has established the independent effectiveness of mirabegron and neuromodulation in the treatment of overactive bladder syndrome. Optimizing the use of these effective and well-tolerated treatment modalities is an important clinical goal and warrants further research. The primary aim of this trial is to answer the questions: how does varying the treatment sequence involving mirabegron and transcutaneous tibial nerve stimulation (TTNS) affect efficacy and patient acceptance and what is the second-line efficacy of either treatment modality?

Primary objective:

To evaluate improvement in storage symptoms, as measured by changes in Overactive Bladder Symptom Score (OABSS), International Prostate Symptom Score (IPSS) and parameters of voiding diary, in overactive bladder (OAB) patients receiving mirabegron or TTNS as first-line therapy when crossed over to second-line therapy with the opposite treatment modality

Secondary objectives:

To evaluate improvement in symptoms, as measured by changes in OABSS, IPSS and parameters of voiding diary, on first-line therapy with mirabegron or TTNS followed by combination multi-modal therapy To evaluate the effect of multi-modal treatment approach on patient's perception of treatment satisfaction and symptom control To evaluate urodynamic profiles of patients treated with multi-modal approach
