Comparison of fesoterodine and tolterodine extended release for the treatment of overactive bladder: a head‐to‐head placebo‐controlled trial
Bibliographic record
Abstract
OBJECTIVE: To compare the efficacy and tolerability of fesoterodine 8 mg with tolterodine extended-release (ER) 4 mg and placebo in a randomized clinical trial of patients with an overactive bladder (OAB). PATIENTS AND METHODS: In this 12-week double-blind, double-dummy, placebo-controlled, randomized clinical trial, eligible patients reported OAB symptoms for > or = 3 months and recorded > or = 8 voids and > or = 1 urgency urinary incontinence (UUI) episode per 24 h in 3-day bladder diaries at baseline. Patients were randomized in a 2:2:1 ratio to fesoterodine (4 mg for 1 week then 8 mg for 11 weeks); tolterodine ER 4 mg; or placebo (with sham dose escalation for tolterodine ER and placebo). Endpoints were changes from baseline to week 12 in UUI episodes (primary endpoint), total and nocturnal voids, urgency episodes, severe urgency episodes, and frequency-urgency sum per 24 h; mean voided volume per void (MVV); and the OAB questionnaire (OAB-q), Patient Perception of Bladder Condition (PPBC), and Urgency Perception Scale (UPS). Safety and tolerability were assessed and summarized over the 12-week study period. RESULTS: Fesoterodine (636 patients) significantly improved UUI episodes at week 12 (primary endpoint) compared with tolterodine ER (641 patients; P = 0.017) and placebo (313 patients; P < 0.001). Fesoterodine also produced significantly greater improvements than tolterodine ER in MVV (P = 0.005). Fesoterodine significantly improved all diary endpoints compared with placebo (P < 0.001), except for nocturnal voids (P = 0.327). Tolterodine ER significantly improved all diary endpoints vs placebo (P < 0.001), except for nocturnal voids (P = 0.506) and MVV (P = 0.103). Diary dry rates (the proportion of patients reporting no UUI episodes at endpoint among those with one or more UUI episodes at baseline) were significantly higher with fesoterodine (64%) than with tolterodine ER (57%; P = 0.015) and placebo (45%; P < 0.001). Improvements in PPBC, UPS and OAB-q scale and domain scores at week 12 were all significantly better with fesoterodine than placebo (all P < 0.001) and tolterodine ER (all P < 0.05) except for the OAB-q Sleep domain vs tolterodine ER (P = 0.081). Dry mouth and constipation rates were 28% and 5% in the fesoterodine group, 16% and 4% in the tolterodine ER group, and 6% and 3% with placebo, respectively. Discontinuations due to treatment-emergent adverse events were 6%, 4% and 2% in the fesoterodine, tolterodine ER, and placebo groups, respectively. CONCLUSION: In patients with OAB, fesoterodine 8 mg showed superior efficacy over tolterodine ER 4 mg and placebo in reducing UUI episodes (primary endpoint) and in improving most patient-reported outcome measures. Both active treatments were well tolerated.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
