How long before vesicare works




















A further study that includes more patients is needed to solve these problems. In conclusion, our study confirmed that the improved urgency and nocturia by solifenacin administration may also improve sleep quality. However, there were no significant differences by administration timing. Although there are various causes of nocturia, this antimuscarinic drug may not only improve storage symptoms by decreasing urgency and nocturia but also improve sleep disruption for OAB patients with sleep disruptions.

YM Study Group. Randomized, double-blind placebo- and tolterodine-controlled trial of the once-daily antimuscarinic agent solifenacin in patients with symptomatic overactive bladder. Reduction from baseline in the number of micturition and urgency episodes in 24 hours, and episodes of nocturia in patients receiving placebo, 5 mg, or 10 mg of solifenacin in a phase 3 trial drawn from data of Cardozo et al Half of the patients who were incontinent at baseline and received treatment with solifenacin 5 mg and 10 mg were dry at the end of the study period.

Rates of dry mouth were 7. Seven patients 2. A week phase 3a study assessing the efficacy of 5 mg and 10 mg solifenacin was conducted in a multicenter, double-blind, placebo-controlled trial, using 2 mg of immediate release tolterodine as an active comparator Chapple et al b. The primary aim was to assess the efficacy of solifenacin 5 and 10 mg whilst the secondary aims were to compare the safety and efficacy with that of 2 mg immediate release IR tolterodine.

After a 2-week placebo run-in period, subjects were randomized to either 2 mg IR tolterodine twice daily, placebo, solifenacin 5 mg or 10 mg. Baseline to end of study changes in the mean number of urgency, mixed incontinence and urgency incontinence episodes were used as study outcome measures. In addition, the mean number of voids per 24 hours and mean volume voided per void were also assessed. Results of the study showed a statistically significant reduction in the number of urgency and urgency incontinence episodes in the patients receiving solifenacin, when compared with placebo.

These changes were not statistically significant in the tolterodine-treated group when compared with placebo. There was a significant reduction in urinary frequency with all active treatments, this effect being greatest in the solifenacin 10 mg, and then the 5 mg group. There was a statistically significant improvement in volume of urine per void in the solifenacin- and tolterodine-treated groups, when compared with placebo.

The changes in study outcome measures are shown in Figure 3. The percentage change from baseline in the mean number of urgency, incontinence, and urge incontinence episodes and mean voids in a hour period Drawn from data of Chapple et al b. Five 1. Constipation was reported in a greater number of patients receiving solifenacin than tolterodine. The study found the 5 and 10 mg doses of solifenacin to be more effective than placebo, in the treatment of OAB.

These preliminary studies lead to the STAR study; a head to head clinical trial comparing the efficacy of the existing market leader tolterodine extended release with dose flexible solifenacin. This was a prospective, double blind, 2 arm, parallel group, week study Chapple et al The study design is described in Figure 4. In this type of study the initial analysis is one of non-inferiority of the test drug, and once established assessment of superiority may follow.

The results of the study showed that solifenacin was not inferior to tolterodine in reducing the number of voids per 24 hours; 2. Solifenacin treatment resulted in a significant improvement in urgency, nocturia, urge incontinence, and overall incontinence when compared with tolterodine.

Reduction in pad usage was significantly greater in the solifenacin-treated group than the tolterodine-treated group 1. The perception of bladder condition questionnaire PBC is a validated single-item questionnaire, which asks people to choose 1 of 6 responses describing the severity of their bladder condition.

Assessment of the PBC questionnaire scores showed a greater improvement in the solifenacin-treated group than the tolterodine-treated group 1. Adverse events were those associated with antimuscarinic therapy and were mild to moderate in severity.

The study concluded that the flexible dosing of solifenacin is more effective in treating OAB compared with the highest licensed dose of extended release tolterodine.

The duration of most clinical trials is 12 weeks, owing, among other factors, to cost constraints, intensity of surveillance, and the ethical considerations of long-term placebo treatment. Patients receive detailed follow up and incentives such as free study medication in order to complete the trial.

Long term real world efficacy and persistence with treatment cannot be easily extrapolated from short-clinical trials. Participants in a week study were offered a week open label extension of solifenacin at both 5 and 10 mg doses. The aim of the study was to assess the long-term efficacy and tolerability of solifenacin Haab et al Participants were followed up at 3 intervals.

Traditional outcome measures such as frequency, urgency, urgency incontinence, and nocturia episodes per hour period and volume voided per void were used. Figure 5 shows the changes in bladder diary variables over the 1-year extension period.

Median percentage reductions in frequency, urgency, and nocturia in long-term solifenacin treated patients. Long term open-label solifenacin treatment associated with persistence with therapy in patients with overactive bladder syndrome. Eur Urol , — More than half of episodes of dry mouth, constipation and blurred vision were mild in severity. The Kings health questionnaire KHQ Kelleher et al b , a domain quality of life instrument designed for the assessment of quality of life among patients with lower urinary tract dysfunction, was used in 2 of the phase 3 studies Chapple et al b ; Cardozo et al and the open label extension study.

Quality of life data analysis of a week trial conducted by Chapple et al b showed a significant improvement in 5 of the domains of the KHQ in patients taking 5 and 10 mg doses of solifenacin compared with placebo role limitations, physical limitations, emotions, severity measures, and symptom severity. Patients taking 10 mg of solifenacin also reported a significantly greater score in the incontinence impact domain. Patients taking the 10 mg dose of solifenacin also reported an improvement in the physical limitations and severity measures domains Figure 6.

Pooled changes from baseline in the KHQ domains for 2 of the phase 3 trials for solifenacin. Quality of life data from the long term extension study showed a significant improvement in 9 of the 10 domains of the KHQ with the exception of the personal relationships domain.

Almost two thirds of this improvement occurred in the first 3 months of treatment and was sustained for the duration of the study. Quality of life improvements continued throughout the week extension period Figure 7. Changes from baseline in the KHQ domains for the open label solifenacin extension study. Previous studies of solifenacin have used changes in micturition frequency as the primary outcome measure of treatment effectiveness.

Two recent trials have used urgency as the primary outcome variable. The Venus trial Vesicare efficacy and safety in patients with urgency study investigated the efficacy and safety of 5 and 10 mg doses of solifenacin using a novel outcome measure of urgency called warning time. Warning time was measured using a stopwatch for a 1-day period prior to study-related visits. The results of the study showed a significant increase in warning time in patients receiving solifenacin, Qualitative measures of urgency were evaluated using the urgency perception scale UPS ; a validated three point scale and the Indevus urgency severity scale IUSS ; a single item patient reported measure of urgency severity Toglia et al a.

Full data from this trial had not been published at the time of preparing of this manuscript. Previous clinical trials evaluating tolterodine and darifenacin have used warning time as an endpoint measure; however have failed to show a significant increase in warning time Toglia b ; Zinner et al Cardozo et al have previously shown a significant improvement in warning time for darifenacin compared to placebo in a randomized, double blind, placebo controlled study.

The dose of darifenacin used was 30 mg, namely twice the maximal licensed dose for the treatment of OAB. The week Sunrise study solifenacin in the treatment of urgency symptoms of OAB in a rising dose, randomized, placebo controlled, double blind, efficacy trial assessed the effects of 5 and 10 mg solifenacin on urgency severity and bother.

The majority of clinical trials of OAB treatments use frequency and incontinence episodes as primary outcome variables as they are easy to objectively measure. Urgency is difficult to measure but remains the defining and most bothersome symptom of OAB and as such of greatest importance to patients and prescribers Cardozo et al a. Urgency severity and bother were chosen as the primary end points for the study.

The perception of bladder condition PBC which is a validated, single item questionnaire, and a treatment satisfaction visual analogue scale were also used.

Traditional bladder diary measurements namely, frequency, urgency and incontinence episodes per 24 hours were used as secondary outcome variables.

Patients receiving solifenacin achieved a significantly greater reduction in urgency, frequency, and urge incontinence episodes when compared with placebo. These trends were also reflected in the qualitative measures. There was a Treatment satisfaction was significantly increased. The incidences of dry mouth and constipation were higher in patients receiving solifenacin The rate of blurred vision was equivocal.

Discontinuation rates for solifenacin and placebo were similar Full data from this trial had not been published at the time of preparing this manuscript. Solifenacin was launched in as the first once-daily, flexible-dose, M3-receptor-selective antimuscarinic for the treatment of OAB. Long-term safety, efficacy, tolerability, and persistence with treatment have been established in an open label week continuation study.

Higher doses of solifenacin are not associated with higher rates of discontinuation. In addition, recent studies utilizing an array of measures of urgency have shown that irrespective of the measure used urgency is improved by solifenacin.

A large post-marketing head-to-head study comparing solifenacin flexible dose and extended release tolterodine fixed dose showed a significant benefit of solifenacin treatment. In clinical practice, patients are commenced on 5 mg of solifenacin and offered dose titration at 4—6 weeks of treatment. This may enhance treatment efficacy, and allow optimum control of OAB. Whether optimal dose titration in clinical practice mirrors that seen in clinical trials is yet to be established.
