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.

AUCI287τ,SS - Area under the serum insulin 287 concentration-time curve during one dosing interval at steady state
Measured in pmol\*h/L
Time frame: From 0 to 168 hours after trial product administration (day 50)
Number of adverse events (AEs)
Number of events
Time frame: From first trial product administration (day 1) to end of last dosing interval (day 57 for insulin 287, day 15 for IGlar)
Number of hypoglycaemic episodes
Number of episodes
Time frame: 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
Change in antiinsulin 287 antibody level
Measured in % B/T (percentage of bound tracer measured after precipitation to total tracer)
Time frame: From first insulin 287 administration (day 1) to follow-up visit (day 106)
Change in antiinsulin 287 antibody titres
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.
Time frame: From first insulin 287 administration (day 1) to follow-up visit (day 106)
Positive cross-reactive anti-human insulin antibodies
Yes/no. Number of participants who developed/not developed positive cross-reactive anti-human insulin antibodies.
Time frame: At follow-up visit (day 106)
