The primary objective of this study is to obtain efficacy and safety descriptive data on 2 different titration algorithms: the INSIGHT titration algorithm (self-titration of 1 unit/day) and the EDITION trial algorithm with insulin glargine 300 units/mL when given as basal insulin in uncontrolled type 2 diabetes mellitus (T2DM) patients on basal insulin with or without non-insulin anti-hyperglycemic agent (NIAHA) or in insulin naïve patients.
