The purpose of the study is to investigate whether the combination of insulin pump therapy and continued glucose monitoring (CGM) is superior to multiple daily insulin injections to prevent progression of albuminuria in patients with type 1 diabetes

Condition Intervention Phase
Type 1 Diabetes Mellitus
Device: Insulin pump therapy (CSII) plus continuous glucose monitoring (CGM)
Other: Multiple daily insulin injections (MDI)
Phase 4

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: The Effect of Sensor-Augmented Continuous Subcutaneous Insulin Infusion Compared to Multiple Daily Insulin Injections in Prevention of Increasing Urinary Albumin Excretion Rate in Type 1 Diabetes Mellitus

Primary Outcome Measures:
  • difference in change in urine albumine excretion from baseline to end of study (12 months) [ Time Frame: 12 months ]
    Urine albumin excretion is evaluated at screening, at entry, after 1,3,6,9, and 12 months.

Secondary Outcome Measures:
  • difference in change of HbA1c from baseline to 12 months [ Time Frame: 12 months ]
  • difference in change in self-monitored blood glucose (SMBG) measurement 4-point glucose profiles [ Time Frame: 12 months ]
  • difference in change of 24-hour blood pressure [ Time Frame: 12 months ]
  • difference in change of glomerular filtration rate (GFR) [ Time Frame: 12 months ]
  • difference in the occurence or progression of retinopathy [ Time Frame: 12 months ]
  • difference in change of cardiovascular biomarkers of inflammation, lipid metabolism and NT-proBNP [ Time Frame: 12 months ]
  • difference in endothelial cell dysfunction [ Time Frame: 12 months ]
  • difference in carotid intima media thickness (CIMT) [ Time Frame: 12 months ]

Enrollment: 60
Study Start Date: December 2011
Study Completion Date: December 2014
Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: CSII plus CGM
Patients who has never been treated with insulin pump are randomized to 12 months with insulin pump therapy plus continuous glucose monitoring.
Device: Insulin pump therapy (CSII) plus continuous glucose monitoring (CGM)
Randomization to 12 months with CSII plus CGM
Other Names:
  • CSII
  • CGM
  • Medtronic MiniMed Paradigm REAL-Time System
  • Medtronic MiniMed Paradigm Veo
  • Sensor augmented insulin pump therapy
Active Comparator: Multiple daily insulin injections
randomized to 12 months standard/usual insulin regimen (multiple daily injections). (stays on insulin pen).
Other: Multiple daily insulin injections (MDI)
Randomization12 months therapy with MDI
Other Names:
  • Human insulin
  • Insulin analogues

Detailed Description:

80 type 1 diabetic patients with kidney function (GFR > 45 ml/min), but with urine albumin excretion of at least 30 mg/day and HbA1c 7.5-13.0% are randomised to either multiple daily insulin injections (control group) or insulin pump therapy plus continued glucose monitoring (CGM) (intervention group). Patients must be in stable RAAS blockade before entering the study.

Before the study is initiated all patients receive education in intensive diabetes treatment and self-care including carbohydrate counting.

Patients return to the clinic after 1,3,6,9, and 12 months for measurement of urine albumine excretion, clinical examination including blood pressure, CGM sensor readings, four-point self monitored blood glucose (SMBG) profiles, blood samples and fulfillment of questionnaire to assess quality of life. At entry and after 12 months, eye fundus foto, 24-hour blood pressure, GFR, and carotis intima media thickness (CIMT)are also evaluated.
