Brief Summary

The purpose of this study is to evaluate the comparative efficacy of insulin pump therapy versus multiple daily injections in insulin-taking type 2 diabetes mellitus who are sub-optimally controlled with premixed insulin regimen. This research is necessary because many patients with type 2 diabetes mellitus do not meet their glucose targets.

In advanced Type 2 diabetes mellitus, many patients develop worsening diabetes control and unable to reach the glucose targets despite intensive insulin regimens.This is further complicated by the risks of low blood sugar and weight gain. These limitations of multiple daily injection treatment show the need for new treatments for this group of patients.

Detailed Description

This study evaluates between group change in glycemic control (HbA1c) after 6 months of insulin pump therapy in patients with type 2 Diabetes Mellitus, as compared to patients on multiple daily injections (MDI) therapy over the same time period. It also evaluates between group changes in diabetes clinical outcomes after 6 months in patients with type 2 DM. Patient related outcomes will be measured after 6 months of therapy. The primary endpoint will be between group difference in average HbA1c changes from baseline to 6 months, when comparing Continuous Subcutaneous Insulin Infusion (CSII) to MDI.

The secondary end point concerns the safety issues such as severe hypoglycemia incidence: defined as an episode absolutely requiring assistance from another person and preferably accompanied by a confirmatory blood glucose by finger stick of less than 50mg/dL (2.8 mmol/L), (i.e., subject is unable to treat self and requires carbohydrate, glucagon or other resuscitative actions to prevent further clinical deterioration), hospitalizations, Diabetic Ketoacidosis (DKA), an acute metabolic complication of diabetes, characterized by hyperglycemia, hyperketonemia, and metabolic acidosis, within group difference in HbA1c from 6 months to 12 months, change in weight or BMI, change in Lipids : total cholesterol, high density lipoprotein(HDL),low density lipoprotein(LDL),triglyceride, change in blood pressure, Insulin Dosage Changes (Total Daily Dose), Number of self monitoring blood glucose (SMBG)/day, treatment satisfaction: Diabetes Treatment Satisfaction Questionnaire status and change version (DTSQs and DTSQc).

The hypotheses underlying the secondary outcomes : the pump therapy improves glycaemic control whilst utilizing less total daily dose of insulin in comparison to multiple daily injections of insulin. This is associated with parallel improvement in metabolic profiles such as blood pressure and lipids. As for the glucose monitoring, investigators want to evaluate whether there is any difference in the frequency of SMBG/day between the 2 treatment groups. More frequent SMBG monitoring denotes better compliance, motivation and empowerment by the participants to control their diabetes.

7. Patients must be willing to undergo all study procedures

8. Female patients of child-bearing potential must be using adequate contraception means as assessed by Investigator

CRITERIA FOR INCLUSION AT RANDOMISATION

1. Diagnosed with type 2 DM, as per Investigator diagnosis

2. HbA1c (DCCT-standard) must be ≥ 9.0% and ≤12%

3. Insulin resistance defined as required daily dose up to 1.5 U/Kg or a maximum of 200 units per day

4. On premixed regimen (human or analogue insulin) defined as ≥ 2 injections per day for at least 3 months prior signing the informed consent

5. Ability to comply with technology, according to Investigator's judgment

6. ≥ 2.5 SMBG per day on average

7. Patients must be willing to undergo all study procedures

8. Female patients of child-bearing potential must be using adequate contraception means as assessed by Investigator

Exclusion Criteria

CRITERIA FOR EXCLUSION (AT SCREENING AND RANDOMISATION)

1. Subject has a history (≥ 2 events) of hypoglycemic seizure or hypoglycemic coma within the last 6 months

2. Subject is pregnant as assessed by a pregnancy test with central laboratory, or plans to become pregnant during the course of the study

3. Participation in another interventional clinical study, on-going or completed less than 3 months prior to signature of Patient Informed Consent.

4. Subject has proliferative retinopathy or sight threatening maculopathy

5. Subject has

• an acute coronary syndrome (myocardial infarction or unstable angina) within 12 months OR
• coronary artery revascularization by bypass surgery or stenting within 3 months OR
• a transient ischemic attack (TIA) or cerebrovascular accident (CVA) within 3 months OR
• hospitalization for heart failure within 3 months or current New York Functional Class III or IV OR
• current 2nd or 3rd degree heart block OR
• symptomatic ventricular rhythm disturbances OR
• thromboembolic disease within the last 3 months OR

6. Subject with renal impairment expressed as estimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease (MDRD) formula < 30 ml/min as demonstrated by the screening central laboratory value at the time of enrollment

7. Subject has taken oral or injectable steroids within the last 30 days.

8. Systolic blood pressure on screening visit is > 180 mmHg

9. Diastolic blood pressure on screening visit is > 110 mmHg

10. Any other disease (eg active cancer under treatment) or condition including abnormalities found on the screening tests, that in the opinion of the Investigator, may preclude the patient from participating in the study

11. Taking any medication prescribed for weight loss

12. Alcohol or drug abuse, other than nicotine, at the Investigator's discretion Use of a Glucagon Like Peptide-1 agonist or pramlintide (Symlin®). Glucagon Like Peptide-1 slows gastric emptying, thereby decreasing the rate of glucose absorption. Pramlintide (Symlin®) is a commercially available analogue of amylin, a synergistic partner to insulin.
