Study summary

The transition from the Pediatric clinic to the adult care is a challenging period for young adults with type 1 diabetes, due to the high risk of poor glycemic control. Achieving the glycemic target without hypoglycemia and/or large glucose excursions is of paramount importance for type 1 diabetic patients, who have high variability of daily glucose levels . Both insulin pump therapy and multiple daily injections of insulin are recommended strategy to achieve glycemic control in type 1 diabetes; however, no studies investigated the effects of insulin pump vs insulin injections on glycol-metabolic outcomes in the transition phase. The aim of this study was to evaluate the effects of continuous subcutaneous insulin infusion (CSII) therapy, as compared with multiple daily injections of insulin (MDI), on glycemic and metabolic control, in young type 1 diabetic patients transitioned to the adult diabetes care.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • T1DM for at least 12 months
  • persistent levels ≥ 7.5% (58 mmol/mol) despite optimized education therapy,
  • recurrent severe hypoglycemic episodes or high glucose variability
  • willingness to wear the insulin pump

Exclusion criteria

Exclusion Criteria:

  • previous use of insulin pump
  • pregnancy or planning to become pregnant in the next 2 years,
  • lack of ability to use the study devices
  • history of severe chronic diseases
  • recent or concomitant use of
  • drug or alcohol abuse
  • psychiatric complaints that interfere with the correct use of the devices
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. HbA1c change

    Within and between groups difference in HbA1c levels

    Time frame: Baseline, 6 months, 12 months, 24 months

  2. Change in mean amplitude glucose excursions (MAGE

    Within and between groups difference in glucose variability measured as mean amplitude of glucose excursions (MAGE).

    Time frame: Baseline, 6 months, 12 months, 24 months

  3. Change in coefficient of variation (CV)

    Within and between groups difference in glucose variability measured as coefficient of variation (CV).

    Time frame: Baseline, 6 months, 12 months, 24 months

  4. Change in standard deviation (SD) of mean glucose levels

    Within and between groups difference in glucose variability measured as standard deviation (SD) of mean glucose levels

    Time frame: Baseline, 6 months, 12 months, 24 months

  5. Change in glucose variability

    Within and between groups difference in time in the euglycemic range, defined as the minutes per day spent in glucose levels ranging between 70-180 mg/dL

    Time frame: Baseline, 6 months, 12 months, 24 months

Secondary outcomes

  1. Occurrence of hypoglycemic events

    Number of events of mild hypoglycemia (glucose levels below 70 mg/dl), or severe hypoglycemia (below 54 mg/dl or each episode of low glucose levels requiring assistance)

    Time frame: Through study completion, an average of 1 year

  2. Change in weight

    Time frame: Baseline, 12 months, 24 months

  3. Change in lipid profile

    Difference between groups in total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides

    Time frame: Baseline, 12 months, 24 months

  4. Total daily insulin doses/Kg

    Time frame: Baseline, 12 months, 24 months

  5. Diabetes treatment satisfaction

    In order to measure satisfaction with diabetes treatment regimens, we used the self-reported Diabetes Treatment Satisfaction Questionnaire. This instrument aims to assess levels of satisfaction in subjects using different treatment strategies. The questionnaire consists of eight questions: six questions addresses general satisfaction with a score from 0 to 6 for each question (0 = worst), that has to be computed in a total score ranging from 0 (=worst) to 36 (=best); among the remaining two questions, which has to be computed separately as two subscales, one concerns the perception of hyperglycemic events and another the perception of hypoglycemic events, both with a score from 0 (none of the time) to 6 (most of the time).

    Time frame: Baseline, 12 months, 24 months

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 15, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
