Safety and tolerability was assessed
by collating data on adverse events (AEs)
using the Medical Dictionary for Regulatory
Activities (MedDRA version 12.1),
hypoglycemic events, laboratory tests, calculated
creatinine clearance, urinary glucose/
creatinine ratio, electrocardiographic and
physical examinations, and vital signs.
In addition, patients were actively questioned
at each study visit to assess signs,
symptoms, and reports suggestive of genital
infections and urinary tract infections
(UTIs). These responses, and those obtained
spontaneously, were categorized
in the database using a predefined list of
MedDRA terms suggestive of genital infections
and UTIs.
