Trial Outcomes & Findings for A Study to Evaluate Tolerability and Participants Preference Between Mirabegron and Tolterodine Extended Release (ER) in Participants With Overactive Bladder (OAB) (NCT NCT02138747)

NCT ID: NCT02138747

Last Updated: 2020-02-26

Results Overview

The medication tolerability scale measured the level of bothersomeness related to the occurrence of a side effect that was known to be related to the approved OAB medication (i.e., constipation, dry mouth, drowsiness, headache, nausea and blurred vision). The OAB medication tolerability score was calculated as a sum of the responses and converted to a scale from 0 to 100, where higher score indicates better perceived OAB medication tolerability (less bother from side-effects).

Participant Flow

Recruited participants were male and female over 18 years of age with overactive bladder (OAB) symptoms and naïve to pharmacologic treatment. The study was conducted at 36 sites (8 sites in Canada and 28 sites in the US).

After screening, participants were randomized into 1 of 4 sequences in a 5:5:1:1 ratio (mirabegron/tolterodine extended release (ER), tolterodine ER/mirabegron, mirabegron/mirabegron or tolterodine ER/tolterodine ER. Each participant completed 2 double-blind treatment periods with a 2-week washout period between the two periods.

AB: Mirabegron/Tolterodine ER
In the treatment sequence AB participants received 25 mg of mirabegron (Myrbetriq) oral controlled absorption system (OCAS) modified-release tablets and 4 mg of placebo-to-match (PTM) tolterodine ER (Detrol LA) orally once a day during period 1. In the period 2, participants received 4 mg of tolterodine ER and 25 mg of PTM mirabegron orally once a day.

PRIMARY outcome

Timeframe: Week 8 (End of Period 1) and Week 18 (End of Period 2)

Population: The Full Analysis Set (FAS) comprised of all randomized participants who received at least 1 dose of double blind study drug and had filled out OAB-S tolerability scale at least once for a postbaseline visit. Last observation carried forward imputation (LOCF) was utilized.

The medication tolerability scale measured the level of bothersomeness related to the occurrence of a side effect that was known to be related to the approved OAB medication (i.e., constipation, dry mouth, drowsiness, headache, nausea and blurred vision). The OAB medication tolerability score was calculated as a sum of the responses and converted to a scale from 0 to 100, where higher score indicates better perceived OAB medication tolerability (less bother from side-effects).

Timeframe: Week 18 (End of Period 2)

Population: Full Analysis Set (FAS-PNP \[Preference/No Preference\]) consisted of all randomized participant who took at least 14 days of double-blind study drug in each treatment period and had filled out the patient preference form.

Participants were asked to choose which treatment period they preferred and the degree of preference. Preference was assessed on a 5-point scale assessed at the end of period 2 ("strong preference for period 1," "mild preference for period 1," "no preference," "mild preference for period 2," "strong preference for period 2"). Participants who selected either a "mild preference" or "strong preference" were considered as having a preference for a specific study drug and participants who selected "no preference" were considered as having no preference for one study drug over the other study drug."
