OBJECTIVES To examine the effects of the antimuscarinic agent solifenacin on urinary urgency, using a range of novel and established outcome measures, as urgency is the principal symptom of the overactive bladder syndrome (OAB). PATIENTS AND METHODS The study (SUNRISE, solifenacin in the treatment of urgency symptoms of OAB in a rising dose, randomized, placebo‐controlled, double‐blind, efficacy trial) was a randomized, double‐blind, 16‐week, placebo‐controlled, multicentre study of solifenacin 5/10 mg in 863 patients with symptoms of OAB for ≥3 months. The primary efficacy variable was the change from baseline to endpoint in the number of episodes of severe urgency with or without urgency incontinence per 24 h, as measured using the Patient Perception of Intensity of Urgency Scale, grade 3 + 4. Secondary efficacy variables included patient‐reported outcomes for bladder condition, urgency bother and treatment satisfaction. A 3‐day voiding diary was used to record micturition frequency and episodes of urgency and incontinence. A 7‐day diary was used to assess speed of onset of effect. RESULTS Solifenacin 5/10 mg was significantly more effective than placebo in reducing the mean number of episodes of severe urgency with or without incontinence per 24 h from baseline to endpoint (−2.6 vs −1.8, P < 0.001). There were also statistically significant differences in favour of solifenacin 5/10 mg over placebo for all secondary variables measured at endpoint, including patient‐reported outcomes. There was a significant improvement in urgency as early as day 3 of treatment. Treatment‐emergent adverse events with solifenacin 5/10 mg were mainly mild or moderate in severity, and only led to discontinuation in 3.6% of patients. CONCLUSION Solifenacin significantly reduced the number of urgency episodes and the extent of urgency bother, and was well tolerated; it was effective as early as day 3 of treatment.

These results suggest that telomerase could be a good diagnostic marker for the early noninvasive identification of patients with bladder carcinoma by facilitating the detection of exfoliated immortal cancer cells in their urine.
