Percentage of Participants With CK >=10 x ULN With Muscle Symptoms
Participants had CK levels assessed during Period I (4 weeks ) throughout each 8 week treatment period (20 weeks total). Participants who had an assessment of CK that was 10 x ULN or greater and had associated muscle symptoms present within +/- 7 days were recorded. The ULNs for males and females were 207 U/L and 169 U/L, respectively.

Percentage of Participants With CK >=10 x ULN With Muscle Symptoms - Drug Related
Participants had CK levels assessed during Period I (4 weeks ) throughout each 8 week treatment period (20 weeks total). Participants who had an assessment of CK that was 10 x ULN or greater and had associated muscle symptoms present within +/- 7 days that were reported as at least possibly related to study drug were recorded. The ULNs for males and females were 207 U/L and 169 U/L, respectively.
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.
Time frame: up 20 weeks (12 weeks in Period I/II and 8 weeks in Period III)
Percentage of Participants With New Diagnosis of Diabetes
Participants who with newly diagnosed of diabetes were recorded. 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.
Time frame: up 20 weeks (12 weeks in Period I/II and 8 weeks in Period III)
Percentage of Participants With Worsening of the Pre-existing Conditions of Diabetes in Participants With Diabetes at Baseline
Participants with diabetes at baseline and who experienced a worsening of the diabetes identified through adverse event reports using a pre-defined set of terms and/or increasing dose/adding a new anti-diabetic medication.
Time frame: up 20 weeks (12 weeks in Period I/II and 8 weeks in Period III)
Percentage of Participants With a Confirmed Adjudicated Cardiovascular Event
Select serious adverse cardiovascular events and all-cause mortality that occurred during the treatment phase of the study were adjudicated by an expert committee external to the sponsor. Those events confirmed by the committee as cardiovascular events were recorded
Time frame: up 20 weeks (12 weeks in Period I/II and 8 weeks in Period III)
Percentage of Participants Who Experience at Least 1 Clinical Adverse Event (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. A clinical AE was an AE reported as a result of a clinical examination or reported by the participant.
Time frame: up 20 weeks (12 weeks in Period I/II and 8 weeks in Period III)
