A Study of the Safety and Efficacy of MK-1293 Compared to Lantus™ in Participants With Type 1 Diabetes Mellitus (T1DM) (MK-1293-003)

Phase 3CompletedNCT02059161

Merck Sharp & Dohme LLC508 enrolled

Overview

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-1293DRUG

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™DRUG

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.

Outcomes

Primary Outcomes

Primary: Change From Baseline in Hemoglobin A1c (A1C) at Week 24

A1C is blood marker used to report average blood glucose levels over prolonged periods of time and is reported as a percentage (%). This change from baseline reflects the Week 24 A1C minus the Week 0 A1C.

Time frame: Baseline and Week 24

Percentage of Participants With Any Confirmed Positive Anti-insulin Antibody (AIA) at Any Time Up Through Week 24

Percentage of participants with confirmed positive AIA at any time up through Week 24 including baseline.

Time frame: Up to Week 24

Percentage of Participants With Negative AIA at Baseline Who Develop Confirmed Positive AIA at Any Time Up Through Week 24

Percentage of participants who became positive to AIA at or before Week 24, among participants who were AIA negative at baseline.

Time frame: Up to Week 24

Change From Baseline in AIA Titer After 24 Weeks of Treatment

This immunogenicity analysis will assess the effect of treatment with MK-1293 compared with Lantus on anti-insulin antibody development after 24 weeks of treatment. This change from baseline reflects the Week 24 AIA titer minus the Week 0 AIA titer.

Time frame: Baseline and Week 24

Percentage of Participants Who Develop Insulin Neutralizing Antibodies Up Through Week 24

Percentage of Participants Who Develop Insulin Neutralizing Antibodies Up Through Week 24. This immunogenicity analysis assessed the effect of treatment with MK-1293 and with Lantus on insulin-neutralizing antibody (INab) development up through 24 weeks of treatment.

Time frame: Up to Week 24

Participants will continue their prandial insulin during the study.

A1C is blood marker used to report average blood glucose levels over prolonged periods of time and is reported as a percentage (%). This change from baseline reflects the Week 52 A1C minus the Week 0 A1C.
