Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trial of another drug and may not reflect the rates observed in practice.

The safety of ANTUROL was evaluated in 626 patients (210 randomized to ANTUROL 56 mg/day, 214 randomized to ANTUROL 84 mg/day and 202 randomized to placebo) during a randomized, placebo-controlled, double-blind, 12-week clinical efficacy and safety study. A subset of these 626 patients (N = 77) participated in the 24-week open-label safety extension that followed the placebo-controlled study. Of the 77 patients in the safety extension, 24 were randomized to placebo gel during the double-blind, placebo-controlled 12-week study. In the combined double-blind, placebo-controlled study and the open-label safety extension, a total of 441 patients were exposed to at least one dose of ANTUROL. 364 patients received at least 12 weeks of ANTUROL treatment and 66 patients received an additional 24 weeks of ANTUROL treatment during the open-label safety extension. The study population primarily consisted of women (87%) of Caucasian descent (87%) with an average age of 59 years who had overactive bladder with urge urinary incontinence.

Table 1 lists adverse reactions (ARs), regardless of causality, that were reported in the randomized, double-blind, placebo-controlled 12-week study at an incidence greater than placebo and in greater than 3% of patients treated with ANTUROL.

Overall, 672 ARs were experienced by 51.9% of patients. Majority of the ARs were mild to moderate in intensity. The AR most commonly reported was dry mouth which was experienced by a greater proportion of patients in the oxybutynin group than the placebo group (26 patients [12.1%] in the oxybutynin 84 mg group, 10 patients [5.0%] in the placebo group). Application site erythema was the next most commonly reported AR (8 patients [3.7%] in the oxybutynin 84 mg group and 2 patients [1.0%] in the placebo group). Other commonly reported ARs experienced by more patients in the oxybutynin groups compared with placebo were application site rash (7 patients [3.3%] in the oxybutynin 84 mg group and 1 patient [0.5%] in the placebo group); application site pruritus (6 patients [2.8%] in the oxybutynin 84 mg group and 1 patient [0.5%] in the placebo group). The overall rate of application site adverse reactions of any kind was 14.2% in patients receiving ANTUROL as compared to 3.7% in patients receiving placebo. Other cholinergic AEs < 2% in occurrence include dry eyes and blurred vision.

There were no deaths during the study. There were no clinically meaningful changes in vital signs, laboratory values, or ECG examinations over the course of the study.

Table 1: Commonly Reported Adverse Reactions that were reported In greater than 3% of patients treated with ANTUROL and at an incidence greater than placebo.

Preferred Term1 Treatment Group
84 mg/day
n (%) n (%)
Dry mouth 26 (12.1) 10 (5.0)
Application site erythema 8 (3.7) 2 (1.0)
Application site rash 7 (3.3) 1 (0.5)
1 Each patient is counted only once within each treatment, body system and preferred term. All percentages are based on number of patients in the ITT population within each treatment group as denominator.

During the 24-week open-label safety extension, the most commonly reported ARs were urinary tract infection and nasopharyngitis reported in 4 patients each (5.2%), followed by conjunctivitis and application site erythema (both occurred in 3 patients [3.9%]). One patient prematurely discontinued due to the application site erythema and pruritus (both considered to be of mild severity).
