Type 1 Diabetes Mellitus

Brief summary

The purpose of this study is to compare the safety and efficacy of MK-1293 to Lantus™ in participants with T1DM. The primary hypothesis is that after 24 weeks, the mean change in hemoglobin A1c (A1C) from baseline is non-inferior in participants treated with MK-1293 compared with participants treated with Lantus™.

Interventions

MK-1293 dosed subcutaneously once daily at bedtime for 52 weeks. Initial dose will be determined based on the participant's previous insulin therapy. Thereafter, the dose will be titrated to the suggested target for fasting fingerstick glucose levels. MK-1293 dosing once daily at times other than bedtime will be permitted for participants with a previously established dosing time.

Lantus™ dosed subcutaneously once daily at bedtime for 52 weeks. Initial dose will be determined based on the participant's previous insulin therapy. Thereafter, the dose will be titrated to the suggested target for fasting fingerstick glucose levels. Lantus™ dosing once daily at times other than bedtime will be permitted for participants with a previously established dosing time.

Participants will continue their prandial insulin during the study.
