OpT2mise Glucose Control in Type 2 Diabetes Mellitus (DM) With Insulin Pump Therapy

OpT2mise Glucose Control in Type 2 DM With Insulin Pump Therapy

The purpose of this study is to evaluate the comparative effectiveness of insulin pump therapy versus multiple daily injections in insulin-taking type 2 Diabetes Mellitus who are sub optimally controlled with multiple daily injections (MDI).

The type of study is interventional post-market release. All the devices under investigation have CE mark, and are used within intended use.

This study has been designed to be prospective randomized controlled with a single-arm cross-over in the continuation phase.

Four hundred type 2 Multiple Daily Injections (MDI) treated patients will undergo a screening (run-in) phase of 8 weeks. The aim of the screening phase is to eliminate the study effect that might result in a decrease of HbA1c and to make sure that patients, who are failing current MDI therapy, are selected.

After this screening phase, eligible patients will be randomised to receive either Continuous Subcutaneous Insulin Infusion (CSII) treatment or continue MDI treatment. The study phase is a 6-months phase with 2-arms parallel design.

Inclusion Criteria at screening:

1. Diagnosed with type 2 DM, as per Investigator discretion
2. HbA1c (DCCT-standard) must be ≥ 8.0% and ≤12% as evidenced by central lab value taken at screening
3. Insulin resistance defined as required daily dose between 0.5-1.8 U/Kg or a maximum of 220 units of insulin per day
4. Aged 30 to 75 years old (inclusive)
5. On MDI regimen (basal/bolus regimen with long-acting insulin and rapid acting analogs) defined as ≥ 3 injections per day for at least 3 months prior signing the informed consent
6. Ability to comply with technology, according to Investigator's judgment
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

at randomisation:

1. Diagnosed with type 2 DM, as per Investigator discretion
2. HbA1c (DCCT-standard) must be ≥ 8.0% and ≤12% as evidenced by central lab value
3. Insulin resistance defined as required daily dose between 0.7-1.8 U/Kg or a maximum of 220 units of insulin per day
4. On MDI (basal/bolus regimen with long-acting insulin and rapid acting analogs) defined as ≥ 3 injections per day
5. Ability to comply with technology, according to Investigator's judgment
6. ≥ 2.5 SMBG per day on average, as reported in Carelink clinical during the run-in phase.
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

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 him/her 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

13. Use of a GLP-1 agonist or pramlintide (Symlin)
