Change in fasting proinsulin/insulin ratio from baseline (week 0) to week 30 is presented as ratio to baseline. Results are based on the 'on-treatment without rescue medication' observation period, which started at the date of first dose to either the day of last dose plus 7 days or first initiation of rescue medication, whichever came first.

Change in fasting HOMA-B (homeostasis model assessment beta-cell function) from baseline (week 0) to week 30 is presented as ratio to baseline. Results are based on the 'on-treatment without rescue medication' observation period, which started at the date of first dose to either the day of last dose plus 7 days or first initiation of rescue medication, whichever came first.

Change in fasting HOMA-IR (homeostasis model assessment insulin resistence) from baseline (week 0) to week 30 is presented as ratio to baseline. Results are based on the 'on-treatment without rescue medication' observation period, which started at the date of first dose to either the day of last dose plus 7 days or first initiation of rescue medication, whichever came first.

Short Form (SF)-36 is a 36-item patient-reported survey that measures patient's overall health-related quality of life (HRQoL). SF-36v2™ (acute version) questionnaire measured 8 domains of functional health \& well-being and 2 component summary scores (physical component summary-PCS and mental component summary-MCS). The 0-100 scale scores (where higher scores indicated a better HRQoL) from the SF-36 were converted to norm-based scores to enable a direct interpretation in relation to the distribution of the scores in the 2009 U.S. general population. In the metric of norm-based scores, 50 and 10 corresponds to the mean and standard deviation respectively of the 2009 U.S. general population. Change from baseline (week 0) in the domain scores and component summary (PCS and MCS) scores were evaluated at weeks 30. A positive change score indicates an improvement since baseline. Results are based on the data from the 'on-treatment without rescue medication' observation period.

Change from baseline (week 0) in Diabetes Treatment Satisfaction Questionnaire (DTSQs) was evaluated at week 30. The DTSQs items are scored on a 7-point graded response scale ranging from 6 to 0. Higher scores indicate higher levels of treatment satisfaction for DTSQs items 3 -8. For items 1 and 2 a higher score indicates a higher patient perceived experience of high blood sugars and low blood sugars, respectively. Thus, lower scores indicate a perception of blood glucose levels being "none of the time" unacceptably high (item 1) or low (item 2). The domain score of total treatment satisfaction (total treatment satisfaction score) was computed by adding the six items scores 3-8. The score ranges 0-36. A higher treatment satisfaction score indicates a higher level of treatment satisfaction. Results are based on the 'on-treatment without rescue medication' observation period.

Change in high-sensitivity C-reactive protein (CRP) from baseline (week 0) to week 30 is presented as ratio to baseline. High-sensitivity CRP was measured in mg/L. Results are based on the 'on-treatment without rescue medication' observation period, which started at the date of first dose to either the day of last dose plus 7 days or first initiation of rescue medication, whichever came first.

Change in waist circumference from baseline (week 0) to week 30 was measured. Results are based on the 'on-treatment without rescue medication' observation period, which started at the date of first dose to either the day of last dose plus 7 days or first initiation of rescue medication, whichever came first.

Change in body mass index (BMI) from baseline (week 0) to week 30 was measured. Results are based on the 'on-treatment without rescue medication' observation period, which started at the date of first dose to either the day of last dose plus 7 days or first initiation of rescue medication, whichever came first.

Change in fasting total cholesterol from baseline (week 0) to week 30 is presented as ratio to baseline. Fasting total cholesterol was measured in mmol/L. Results are based on the 'on-treatment without rescue medication' observation period, which started at the date of first dose to either the day of last dose plus 7 days or first initiation of rescue medication, whichever came first.

Change in fasting low density lipoprotein (LDL) from baseline (week 0) to week 30 is presented as ratio to baseline. Fasting LDL was measured in mmol/L.
