A participant was classified as having new onset diabetes if they experienced an adverse Event (AE) related to a diagnosis of diabetes (based on a pre-defined set of Medical Dictionary for Regulatory Activities \[MedDRA\] terms), or if they started taking an anti-diabetic medication during the course of the study. The MedDRA terms were as follows: diabetes mellitus, diabetes mellitus insulin-dependent, diabetes mellitus non-insulin dependent, insulin-requiring type II diabetes mellitus, insulin resistant diabetes, diabetes with hyperosmolarity, latent autoimmune diabetes in adults.

Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which was temporally associated with the use of the product, was also an AE. A clinical AE was an AE reported as a result of a clinical examination or reported by the participant. Participants who were discontinued from the study due to a clinical AE were recorded.

Time frame: up 20 weeks (12 weeks in Period I/II and 8 weeks in Period III)

Population: All participants who received at least 1 dose of study drug. Safety analysis was based on the experiences accumulated during Periods I/II combined, where the study follows a parallel design. A separate safety analysis was performed for Period III (post-crossover). Excludes 6 participants who had an AE that began during the placebo run-in.

Percentage of Participants Who Were Discontinued From the Study Due to a Laboratory AE

An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition which was temporally associated with the use of the product, was also an AE.

Participants who with newly diagnosed of diabetes were recorded.

The MedDRA terms were as follows: diabetes mellitus, diabetes mellitus insulin-dependent, diabetes mellitus non-insulin dependent, insulin-requiring type II diabetes mellitus, insulin resistant diabetes, diabetes with hyperosmolarity, latent autoimmune diabetes in adults.

Time frame: up 20 weeks (12 weeks in Period I/II and 8 weeks in Period III)

Percentage of Participants With New Diagnosis of Impaired Fasting Blood Glucose

Participants had fasting glucose levels assessed during Period I (4 weeks ) throughout each 8 week treatment period (20 weeks total). Participants who had the new diagnosis of impaired fasting blood glucose were recorded. A pre-defined set of MedDRA terms was used to identify participants whose glycemic status became 'impaired' during the course of treatment (from clinical adverse experience reports). The MedDRA terms were as follows: blood glucose increased, blood glucose abnormal, glucose tolerance decreased, glucose tolerance test abnormal, carbohydrate tolerance decreased, glucose tolerance impaired, hyperglycaemia, impaired fasting glucose, impaired insulin secretion, metabolic syndrome, insulin resistance, insulin resistance syndrome.
