What researchers measure

Primary outcomes

  1. Change in HbA1c (Glycosylated Haemoglobin)

    Change from baseline (week 0) in HbA1c was evaluated at week 26. The endpoint was evaluated based on the data from the on-treatment without rescue medication observation period, which was the time period when a participant was on treatment with trial product, excluding any period after initiation of rescue medication and/or premature trial product discontinuation.

    Time frame: Week 0, week 26

Secondary outcomes

  1. Subjects Who Achieve (Yes/no) HbA1c Below 7 Percent (53 mmol/Mol)

    Participants who achieved HbA1c \<7.0%, was evaluated at week 26. The endpoint was evaluated based on the data from the on-treatment without rescue medication observation period, which was the time period when a participant was on treatment with trial product, excluding any period after initiation of rescue medication and/or premature trial product discontinuation.

    Time frame: After 26 weeks of treatment

  2. Change in Body Weight

    Change from baseline (week 0) in body weight was evaluated at week 26. The endpoint was evaluated based on the data from the on-treatment without rescue medication observation period, which was the time period when a participant was on treatment with trial product, excluding any period after initiation of rescue medication and/or premature trial product discontinuation.

    Time frame: Week 0, Week 26

  3. Change in Waist Circumference

    Change from baseline (week 0) in waist circumference was evaluated at week 26. The endpoint was evaluated based on the data from the on-treatment without rescue medication observation period, which was the time period when a participant was on treatment with trial product, excluding any period after initiation of rescue medication and/or premature trial product discontinuation.

    Time frame: Week 0, week 26

  4. Change in Body Mass Index (BMI)

    Change from baseline (week 0) in body mass index (BMI) was evaluated at week 26. The endpoint was evaluated based on the data from the on-treatment without rescue medication observation period, which was the time period when a participant was on treatment with trial product, excluding any period after initiation of rescue medication and/or premature trial product discontinuation.

    Time frame: Week 0, week 26

  5. Number of Treatment Emergent Adverse Events (TEAEs) Recorded

    TEAEs were recorded during weeks 0-31 (26 weeks treatment period+5 weeks follow-up period). Adverse events (AEs) with onset during the on-treatment observation period were considered treatment-emergent. On-treatment observation period: Time period when a participant was on treatment with trial product, including any period after initiation of rescue medication.

    Time frame: Weeks 0-31

  6. Number of Confirmed Hypoglycaemic Episodes Recorded

    Treatment-emergent confirmed hypoglycaemic episodes were recorded during weeks 0-31 (26 weeks treatment period + 5 weeks follow-up period). Hypoglycaemic episodes with onset during the on-treatment observation period were considered treatment-emergent. On-treatment observation period was defined as the time period when a subject was on treatment with trial product, including any period after initiation of rescue medication. Confirmed hypoglycaemic episode is an episode that is severe according to the American Diabetes Association (ADA) classification or plasma glucose value \<3.1 mmol/L with or without symptoms consistent with hypoglycaemia.

    Time frame: Weeks 0-31
