Effectiveness and Safety of Two Approaches to the Management of Type 2 Diabetes Mellitus in Australian Primary Care (RELIANCE)

A Randomised, Multicentre, Open-Label, Parallel-Group, 24-Week Phase IV Study Comparing the Effectiveness and Safety of Two Approaches to the Management of Type 2 Diabetes Mellitus in Australian Primary Care: General Practitioner Initiation of Insulin Glargine Versus the Usual Standard of Care

The primary objective is to demonstrate the improvement in glycosylated haemoglobin (HbA1c) levels after general practitioner (GP) initiation and management of type 2 diabetes mellitus (T2DM) with insulin glargine compared with their usual clinical practice.

The secondary objective is to demonstrate the importance of GP initiation of insulin glargine for the treatment of T2DM.

• History of stroke, myocardial infarction, angina pectoris, coronary artery bypass graft or percutaneous transluminal coronary angioplasty within the previous 12 months
• History of congestive heart failure
• Hypoglycaemia unawareness
• Have had more than one episode of hypoglycaemia (per protocol definition) within 24 weeks before screening

• Currently participating in another investigational study or recent study participation ending < 30 days before screening
• Female patients who are pregnant or breastfeeding
• Female patients of childbearing potential (i.e., ovulating, pre-menopausal, not surgically sterile) must be willing to agree to use a medically accepted contraceptive regimen for the duration of the study.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: General Practitioner initiation with insulin glargine; Patients will be prescribed insulin glargine by their Investigator and they will be taught how to administer insulin glargine according to Australian guidelines. Patients will be treated for 24 weeks.	Drug: INSULIN GLARGINE (HOE901); The dose of insulin glargine will be titrated toward a fasting plasma glucose (FPG) target of 5.5 mmol/L. Treatment with oral antidiabetic drugs (OADs) prescribed before study entry may continue (except Sitagliptin, Acarbose, Rosiglitazone)
Active Comparator: Usual standard of care; Patients will be treated by their Investigator with the usual standard of care for 24 weeks (e.g., OAD dose titration, addition of a second or third OAD, or referral to an endocrinologist)	Drug: Oral Anti Diabetics (OAD); Patients treated with the usual standard of care (OAD dose titration, addition of a second or third OAD or referral to an endocrinologist) until optimal doses are reached to maintain a FPG of 5.5 mmol/L

What is the study measuring?

Primary Outcome Measures

The percentage of patients achieving two consecutive on treatment HbA1c measurements of < or = 7.0%	From week 0 to week 24
Decrease in mean HbA1c level	At week 24
Decrease in mean Fasting Plasma Glucose (FPG)	At week 24
Mean change in body weight	At week 24
