Diabetes Mellitus, Type 1
Conditions
Brief summary
This study will look at how insulin 287 works, if it is safe and the side effects in people who are Japanese with type 1 diabetes. The study will test how insulin goes through your blood, how long it stays there and how the blood sugar is lowered. Insulin 287 is a new medicine. Insulin glargine is already approved to treat diabetes. The study doctors can prescribe insulin glargine. The participants will get both of the insulins in a random order. The participants will get 8 weekly doses of insulin 287 and 14 daily doses of insulin glargine. There will also be a run-in period of 2 days to 7 weeks when the participants inject insulin glargine every day before they start insulin 287 period or insulin glargine period. All doses will be injected under the skin. During the run-in period, the participants adjust the insulin glargine dose and make their blood sugar levels stable. From the run-in period, the participants will take insulin aspart as bolus insulin. The study will last for about 16 - 28 weeks. The participants will have 24 visits with the study doctor. There will be 3 glucose clamps where the participants' blood sugar is tested over time. The participants cannot be in the study if the study doctor thinks that there are risks for their health.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| AUCI287τ,SS - Area under the serum insulin 287 concentration-time curve during one dosing interval at steady state | From 0 to 168 hours after trial product administration (day 50) | Measured in pmol\*h/L |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of hypoglycaemic episodes | From first trial product administration (day 1) to end of last dosing interval (day 57 for insulin 287, day 15 for IGlar) excluding clamp days | Number of episodes |
| Change in antiinsulin 287 antibody level | From first insulin 287 administration (day 1) to follow-up visit (day 106) | Measured in % B/T (percentage of bound tracer measured after precipitation to total tracer) |
| Change in antiinsulin 287 antibody titres | From first insulin 287 administration (day 1) to follow-up visit (day 106) | Number of dilutions. The antibody titer is calculated by diluting the blood serum sample containing antibody in serial ratios (1:2, 1:4, 1:8, 1:16... and so on). Using an appropriate detection method (e.g., colorimetric, chromatographic, etc.), each dilution is tested for the presence of detectable levels of antibody. The assigned titer value is indicative of the last dilution in which the antibody was detected. |
| Positive cross-reactive anti-human insulin antibodies | At follow-up visit (day 106) | Yes/no. Number of participants who developed/not developed positive cross-reactive anti-human insulin antibodies. |
| AUCI287,0-168,FD - Area under the serum insulin 287 concentration-time curve after the first dose | From 0 to 168 hours after trial product administration (day 1) | Measured in pmol\*h/L |
| tmax,I287,FD - Time to maximum observed serum insulin 287 concentration after the first dose | From 0 to 168 hours after trial product administration (day 1) | Measured in hours |
| Cmax,I287,FD - Maximum observed serum insulin 287 concentration after the first dose | From 0 to 168 hours after trial product administration (day 1) | Measured in pmol/L |
| tmax,I287,SS - Time to maximum observed serum insulin 287 concentration after the last dose | From 0 to 168 hours after trial product administration (day 50) | Measured in hours |
