Deaths, Serious Adverse Events (SAEs), Adverse Events (AEs), and Discontinuations Due to AEs

An AE is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition in a patient or clinical investigation subject administered an investigational (medicinal) product and that does not necessarily have a causal relationship with this treatment. An SAE is any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or causes prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, or is an important medical event.

Time frame: AEs collected from Day 1/Period 1 through study discharge (study duration: approximately 45 days). SAEs collected from date of written consent until 30 days post discontinuation of dosing or subject's participation in the study.

AEs of Special Interest

See Outcome Measure 16 for a definition of AEs. AEs of clinical interest for saxagliptin were defined as those relating to the following:skin disorders, infection-related AEs (system organ class \[SOC\]: Infections and Infestations), thrombocytopenia, lymphopenia, hypoglycemia, cardiovascular AEs indicative of acute cardiovascular events, localized edema, fractures, pancreatitis, and AEs of hypersensitivity.

Time frame: AEs collected from Day 1/Period 1 through study discharge (study duration: approximately 45 days).

Glucose, Urine Abnormality: if value \>= 2+ (or if pretreatment value \>= 1+, then \>= 2 \* pretreatment). Blood, Urine Abnormality: if value \>= 2+ (or if pretreatment value \>= 1+, then \>= 2 \* pretreatment).
