The Safety and Efficacy of MK-1293 Versus Lantus™ in Participants With Type 2 Diabetes Mellitus (MK-1293-006)

This 24-week study is a safety and efficacy comparison of MK-1293 and Lantus™ in participants with type 2 diabetes mellitus (T2DM). The primary hypothesis is that after 24 weeks, the mean change in hemoglobin A1c (A1C) from baseline is non-inferior (with margin of 0.4%) in participants treated with MK-1293 compared with that in participants treated with Lantus™.


Eligibility Criteria:

Exclusion Criteria:

* History of type 1 diabetes mellitus or a history of ketoacidosis, or has type 1 diabetes confirmed with a C-peptide \<0.7 ng/mL (0.23 nmol/L)
* One or more severe hypoglycemic episodes associated with hypoglycemic seizures, comas or unconsciousness within the past 6 months
* History of intolerance or hypersensitivity to Lantus™ or contraindication to Lantus™ or one of its excipients based on the label of the country of the investigational site
