On September 25, Harriette Scarpero, MD, Vanderbilt University Medical Center, Nashville, Tennessee, presented the results of a post hoc analysis of pooled data from subjects enrolled in two 12-week randomised, double-blind, placebo-controlled, phase 3 trials. This report presents the post hoc analysis from two 3-year, open-label, extension studies that followed the 12-week trials. The researchers enrolled 890 subjects, of which 705 (79%) were women in the 2 open-label studies. The mean age was 57.7 years, with 32% of subjects over the age of 65 years. Subjects were started on fesoterodine 8 mg and could reduce the dosage to 4 mg, or re-escalate to a higher dosage. All dose reductions or increases occurred at a scheduled site visit and after discussion with the investigator. Efficacy and health outcomes were prespecified to be captured for the first 2 years. The majority of the women opted for the 8-mg dose. During the trials, 12.2% of the women discontinued the medication due to adverse side effects, including 1.8% with dry mouth and 1.3% with constipation. The King’s Health Questionnaire assessed health-related quality of life, and was based on the proportion of subjects reporting in each of 4 categories (“inadequate,” “moderate,” “good,” and “excellent”). Treatment satisfaction was measured at open-label baseline, 4 months, 1 year, and 2 years on a 4-point scale ranging from 1 (“extremely satisfied”) to 4 (“not satisfied”). At 2 years, 94% of women rated their treatment tolerance as predominantly “good” or “excellent,” and 97% of women reported being at least “satisfied” with treatment. “Excellent tolerability was reported by 95% of the subjects,” Dr. Scarpero said. “All groups improved in urgency episodes and 97% of [those] reported they were at least satisfied. The study showed the medication was well tolerated in the long term. The quality-of-life data looks better as time goes on.” Dr. Scarpero added that 49% of subjects opted to continue into the third year of the study. Funding for the original trial was provided by Pfizer Inc.
