Fesoterodine (Toviaz™) extended-release (ER) tablets are currently manufactured by Aesica Pharmaceuticals, Zwickau, Germany (Zwickau). An additional manufacturing location at Pfizer Freiburg, Germany (Freiburg) has been identified. This pivotal bioequivalence (BE) study is being conducted to satisfy the United States (US) Food and Drug Administration (FDA) regulatory requirements for the qualification of the Freiburg manufacturing site. Overall Study Design This is an open-label, randomized, single-dose, 4-period, 4-treatment, 2-sequence, two 2-way crossover study in healthy participants. This study will assess the BE of Fesoterodine (Toviaz™) 4 mg and 8 mg ER tablets manufactured at Zwickau (Reference) versus Freiburg (Test). Study participants will include healthy male and/or female individuals between the ages of 18 and 55 years, inclusive. Approximately 18 participants who fulfill entry criteria will be randomized to 1 of the 2 treatment sequences as shown in the table below.
