Non-inferiority Study to Compare the Efficacy and Safety of Mylan's Insulin Glargine With Lantus® in Type 2 Diabetes Mellitus Patients (INSTRIDE 2)

To test whether Mylan's insulin glargine once daily is non-inferior to Lantus® once daily (both administered in combination with other anti-diabetic drugs) based on the change in HbA1c from baseline to 24 weeks

This trial is a multi-center, open-label, randomized, parallel group trial in patients with T2DM comparing the efficacy and safety of Mylan's insulin glargine with that of Lantus®. Patients with an established diagnosis of T2DM per ADA 2014 criteria and who satisfy the selection criteria will be included in the trial. This will be followed by a 24-week randomized, comparative, parallel-assignment treatment period with Mylan's insulin glargine or Lantus® (in addition to other anti-diabetic drugs). After the treatment period, there will be a follow-up visit; 4 weeks after the patient has been put back on approved medications.

Eligibility Criteria:
Inclusion Criteria:

* Patients with an established diagnosis of T2DM per ADA 2014 criteria who also fulfill the following:

  * Diagnosis established 1 year prior to screening
  * Insulin-naïve OR
  * On Lantus® once daily at stable dose (±15% variation in dose) for at least 3 months prior to screening
* Body mass index (BMI) of 18.50 to 40.00 kg/m2 at screening (both values inclusive).
* Stable weight, with no more than 5 kg gain or loss, in the 3 months prior to screening; this information will be collected by patient interview during medical history.
* Hemoglobin ≥9.0 g/dL at screening
* Glycosylated hemoglobin (HbA1c) of \<10.5% or between 7.5 to 10.5% for insulin naïve patients at screening.

Exclusion Criteria:

* History of hypersensitivity to any of the active or inactive ingredients of the insulin/insulin analog preparations used in the trial, OR history of significant allergic drug reactions.
* History of use of animal insulin within the last 3 years, any insulin other than Lantus® within the last 3 months prior to screening, or use of biosimilar insulin glargine at any time prior to screening.
* Patients requiring basal-bolus insulin therapy or who in the opinion of the investigator require mealtime insulin in order to achieve glycemic control.
* Regular use of immune-modulator therapy in the 1 year prior to screening.
* History of ≥2 episodes of severe hypoglycemia within the 6 months before screening or history of hypoglycemia unawareness (a sample questionnaire is provided in Appendix I) as judged by the investigator.
* History of ≥1 episode of hyperglycemic hyperosmolar coma or emergency room visits for uncontrolled diabetes leading to hospitalization within the 6 months prior to screening.
* Serological evidence of human immunodeficiency virus (HIV), hepatitis B (HbSAg) or hepatitis C (HCVAb) antibodies at screening.
* History of drug or alcohol dependence or abuse during the 1 year prior to screening.
* Receipt of another investigational drug in the 3 months prior to screening (or as per local regulations), or if the screening visit is within 5 half-lives of another investigational drug (whichever is longer), or scheduled to receive another investigational drug during the current trial period.
