| Description | Aims: To investigate the effect on urodynamics of 4 weeks treatment with solifenacin succinate in patients with neurogenic detrusor overactivity ( NDO) due to multiple sclerosis ( MS) or spinal cord injury ( SCI). Methods: SONIC was a prospective, multicenter, double-blind, phase 3b/4 study investigating the efficacy and safety of solifenacin 10mg in patients with NDO due to MS or SCI. Patients ( n = 189) were randomized to placebo or active treatment ( solifenacin 5 mg, 10mg or oxybutynin hydrochloride 15 mg) for 4 weeks, after a 2-week, single-blind, placebo run-in period. The primary endpoint was change in maximum cystometric capacity ( MCC) from baseline to end of treatment. The primary analysis compared solifenacin 10mg versus placebo; all other comparisons were considered secondary. Secondary endpoints included changes in urodynamic parameters, patient-reported outcomes, and safety assessments. Results: In the primary analysis, solifenacin 10mg significantly improved mean change from baseline MCC versus placebo ( P<0.001) and was associated with improvements in bladder volume at first contraction and at first leak as well as detrusor pressure at first leak. Similar results were obtained for oxybutynin versus placebo. Patient perception of bladder condition significantly improved with solifenacin 10mg versus placebo ( P = 0.041). There was a clear improvement in quality of life ( QoL) in the solifenacin arms versus placebo. The overall incidence of adverse events was low. Conclusions: In patients with NDO due to MS and SCI, 4 weeks of treatment with solifenacin 10mg improved urodynamic variables and QoL versus placebo and was well tolerated.
