Abstract

Purpose: Utilization patterns of third-line onabotulinumtoxinA for overactive bladder (OAB) symptoms-including discontinuation and use of other therapeutic options during or after treatment-are not well understood. This retrospective analysis of administrative claims was designed to characterize the unmet need for OAB treatment.

Materials and methods: A retrospective claims analysis of Optum's deidentified Clinformatics® Data Mart Database (2009-2021) was performed among patients with diagnosis of OAB newly starting onabotulinumtoxinA injection (2015-2017). Study measures were evaluated during an 18-month pretreatment baseline and over a minimum of 36 months of follow-up. These included number of injections, days between injections, other measures of onabotulinumtoxinA utilization, use of second-line pharmacologic treatments, use of device and surgical treatment options, and complications.

Results: Of 2505 eligible patients, 535 (21.4%; 66.8 ± 13.3 y, 87.3% females) continued onabotulinumtoxinA throughout the study. The remaining 1970 (78.6%; 71.4 ± 11.6 y, 79.1% females) were considered discontinuers. Of continuers, 57% received ≥5 treatments. Of discontinuers, 84% received ≤2 treatments. Anticholinergics and β3-adrenoceptor agonist medication use declined in all patients from baseline to follow-up; however, the absolute reduction in the proportion with any medication fill was similar across continuers versus discontinuers (21% vs. 18%, p < 0.0001). Sacral neuromodulation was initiated by 15/535 (3%) of continuers and 137/1970 (7%) of discontinuers (p < 0.0001). No patients initiated percutaneous tibial neuromodulation.

Conclusions: Early discontinuation of onabotulinumtoxinA therapy for OAB is common and most discontinuers do not receive alternative treatments. Providers have the opportunity to educate OAB patients with un- or undertreated symptoms regarding alternative options.

Keywords: anticholinergic drugs; discontinuation; onabotulinumtoxinA; overactive bladder; percutaneous tibial neuromodulation; sacral neuromodulation; treatment.
