A Research Study to Compare Insulin 287 Once a Week to Insulin Glargine (100 Units/mL) Once a Day in People With Type 2 Diabetes.

Novo Nordisk A/S247 enrolled

Overview

The study compares 2 medicines for people with type 2 diabetes: insulin 287 (a new medicine) and insulin glargine (a medicine doctors can already prescribe). The study doctors will test insulin 287 to see how well it works compared to insulin glargine. The study will also test if insulin 287 is safe. The study participants will either get insulin 287 or insulin glargine (100 units/mL) - which treatment the participants get is decided by chance. The participants will need to inject their selves every day about the same time. Once a week the participant will need to take 1 extra injection on the same day of the week. The participants will have 16 clinic visits and 14 phone calls with the study doctor. During the study, the doctors will ask you to: 1) measure your blood sugar every day with a blood glucose meter using a finger prick, 2) write down different information in a paper diary daily and return this to your doctor, 3) wear a medical device to measure your blood sugar all the time for 2 weeks 5 times during the study.

Interventions

Insulin 287 once weekly subcutaneous (s.c.) injections at the starting dose of 70 units. Dose adjustment was done for the individual patient based on the three pre-breakfast self-measured plasma glucose values measured on two days prior to titration and on the day of the contact. The insulin dose adjustment should aim to reach an SMPG of 3.9-6.0 mmol/L (70-108 mg/dL)

Insulin glargineDRUG

Insulin glargine (100 U/mL) once daily s.c. injections at the starting dose of 10 units. Dose adjustment will be done for the individual patient based on the three pre-breakfast self-measured plasma glucose values measured on two days prior to titration and on the day of the contact. The insulin dose adjustment should aim to reach an SMPG of 3.9-6.0 mmol/L (70-108 mg/dL).

Number of Treatment Emergent Adverse Events (TEAEs)

An adverse event (AE) is any untoward medical occurrence in a clinical trial subject administered or using a medicinal product, whether or not considered related to the medicinal product or usage. A TEAE was defined as an event that had onset date (or increase in severity) during the on-treatment observation period. The endpoint was evaluated based on the data from on-treatment period, starting at the date of first dose of trial product, and ending at follow-up visit, or the last date on trial product + 5 weeks for once daily insulin and + 6 weeks for once weekly insulin.

Time frame: From baseline (Visit 2) to week 31 (Visit 30)

Number of Hypoglycaemic Alert Episodes (Level 1) (≥3.0 and <3.9 mmol/L (≥54 and <70 mg/dL), Confirmed by BG Meter)

Hypoglycaemia alert value (level 1) was defined as episodes that were sufficiently low for treatment with fast-acting carbohydrate and dose adjustment of glucose-lowering therapy with plasma glucose value of equal to or above (\>=) 3.0 and less than (\<) 3.9 mmol/L (\>= 54 and \< 70 mg/dL) confirmed by BG meter. Number of hypoglycaemic alert episodes (level 1) that occurred from week 0 to week 26 are presented.

Time frame: From baseline (Visit 2) to week 26 (Visit 28)

Number of Clinically Significant Hypoglycaemic Episodes (Level 2) (<3.0 mmol/L (54 mg/dL), Confirmed by BG Meter) or Severe Hypoglycaemic Episodes (Level 3)

Clinically significant hypoglycaemic episodes (level 2) were defined as episodes that were sufficiently low to indicate serious, clinically important hypoglycaemia with plasma glucose value of less than (\<) 3.0 mmol/L (54 mg/dL). Severe hypoglycaemic episodes (level 3) were defined as episodes that were associated with severe cognitive impairment requiring external assistance for recovery. Number of clinically significant hypoglycaemic episodes (level 2), confirmed by blood glucose (BG) meter or severe hypoglycaemic episodes (level 3) that occurred from week 0 to week 26 are presented.

Time frame: From baseline (Visit 2) to week 26 (Visit 28)

Change in Anti-insulin 287 Antibody Titres

Samples from the insulin 287 arm of the study were analysed for anti-insulin 287 antibodies. Confirmed anti-insulin 287 antibody positive samples had an antibody titre value determined. The endpoint was evaluated based on the data from in-trial period, starting at randomisation, and ending at the last direct participant-site contact, or when participant withdrew their informed consent, or the last participant-investigator contact for participants lost to follow-up, or death.

Time frame: From baseline (Visit 2) to week 31 (Visit 30)

Change in Cross-reactive Anti-human Insulin Antibody Status (Positive/Negative)

Anti-insulin 287 or glargine antibodies were classified as negative if % B/T was below a certain cut point. Samples positive for anti-insulin 287 or glargine antibodies were further tested for cross-reactivity to endogenous insulin. Samples not further tested are categorised as not applicable (NA). Unknown refers to samples with insufficient volume to perform analysis. The endpoint was evaluated based on the data from in-trial period, starting at randomisation, and ending at the last direct participant-site contact, or when participant withdrew their informed consent, or the last participant-investigator contact for participants lost to follow-up, or death.

Time frame: From baseline (Visit 2) to week 31 (Visit 30)

Change in Anti-insulin 287 Antibody Level

Change in anti-insulin 287 antibodies level is not assessed because change in anti-insulin 287 antibody titres is a more meaningful way of describing the change in antibody levels. The results for change in anti-insulin 287 antibody titres are reported as a separate endpoint.
