Participant has a serum creatinine greater than 150 µmol/L, or aspartate aminotransferase (AST) or alanine aminotransferase (ALT) greater than 2x upper limit of normal (ULN), or γ-GT greater than 3x ULN and considered clinically significant.
Participant has a hypersensitivity to any components of Myrbetriq (mirabegron), other β-AR agonists, tolterodine or other antimuscarinic agents, or any of the inactive ingredients.
Participant has been treated with an experimental device within 30 days or received an investigational agent within 30 days prior to Screening.
