Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 25 years
  • All sexes
  • No healthy volunteers
  • Adult

Who may be able to join

  • The subject has documented T1D, as defined by the American Diabetes Association and World Health Organization (ADA/WHO) for at least 1 year prior to study enrolment
  • Documented evidence should exist within the patient history of T1D
  • The subject is between 18 and 25 years of age (inclusive) at the time of enrolment
  • The subject has been treated with an insulin pump for at least 3 months
  • The subject has an A1C value ≤ 9% based on analysis from the local laboratory at the time of enrolment
  • ● A1C testing must follow National Glycohemoglobin Standardization Program (NGSP) standards.

  • The subject is willing to follow all study instructions
  • Subject is available for the entire study duration and follow-up visits
  • Subject is willing to perform daily self-monitoring of blood glucose (SMBG) and required sensor calibrations
  • If subject has celiac/Hashimoto disease, the disease has to be adequately treated as determined by the investigator
  • Subject has a BMI above 5th centile and below 95th centile for age, respectively.

Who cannot join

  • Concomitant diseases that influence metabolic control (e.g. anemia, significantly impaired hepatic function, renal failure, history of adrenal insufficiency) or other medical conditions, which in the investigator's opinion, may compromise patient safety; Note: Adequately treated thyroid disease and celiac disease do not exclude subjects from enrollment.
  • Significant co-morbidity that, in the opinion of the investigators would preclude participation in the study (e.g. current treatment for cancer, mental disorder)

  • Subject is taking antidiabetic agents or other medications, which could be a contraindication to participation in the study by the judgment of the investigator.
  • Subject is participating in another study of a medical device or drug that could affect glucose measurements or glucose management or Receipt of any investigational medical product within 1 month prior to screening (Visit 1).

About this study

Official title: Day and Night Closed-Loop Glycemic Control With Faster-Acting Insulin Aspart in Young Adults With Type 1 Diabetes Using DreaMed Glucositter - The Fast PHYSI-DREAM Study

A randomized, double-blinded (for insulin type), single centre, crossover design young adult study, on 20 subjects with type 1 diabetes (T1D), aged 18 to 25 (inclusive) years, measuring time in glucose values within 3.9 - 10 mmol/l (70-180 mg/dl) under supervision of DreaMed Glucositter using either faster-acting insulin Aspart (Fiasp®, European Medicines Agency number EMEA/H/C/004046) or normal acting insulin Aspart.

Study duration will be about 3 weeks per subject, 5 month overall.

The objectives of this clinical investigation is:

  1. to evaluate the safety and efficacy of blood glucose control using the DreaMed Glucositter with Fiasp® in young adults with T1D during and after unannounced afternoon physical activity and unannounced meals, in a controlled in-hospital environment.

Primary endpoint is significant between-group difference (intervention Fast-CL versus control Regular-CL) in time within range of glucose values within 3.9 - 10 mmol/l (70-180 mg/dl) during the unannounced afternoon exercise and unannounced standardized meals from 15:00 till 18:00 next day based on sensor glucose readings.

Being tested
Fast-CL, Regular-CL
Medical subject headings
Diabetes Mellitus, Type 1

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Fast-CLDrug

    Also called Faster Acting Insulin Aspart and DreaMed Glucositter

    After the admission we will insert new insulin (blinded) into the insulin pump. At 13:00 they will have lunch (with manual bolus). At 15:00 we will start CL control, participants/investigators will not be allowed to deliver manual bolus till the end of the study period. All meals and afternoon exercise (in the time between 16:30 and 19:30) will be unannounced and managed with CL.

  • Regular-CLDrug

    Also called Insulin Aspart and DreaMed Glucositer

    After the admission we will insert new insulin (blinded) into the insulin pump. At 13:00 they will have lunch (with manual bolus). At 15:00 we will start CL control, participants/investigators will not be allowed to deliver manual bolus till the end of the study period. All meals and afternoon exercise (in the time between 16:30 and 19:30) will be unannounced and managed with CL.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time within range 3.9 - 10 mmol/l (70 - 180 mg/dl)

    Primary endpoint is significant between-group difference (intervention Fast-CL versus control Regular-CL) in time within range 3.9 - 10 mmol/l (70 - 180 mg/dl) during the unannounced afternoon exercise and the afternoon/night after (till 18:00 next day) based on sensor glucose readings.

    Measured: 28 hours

Questions about this trial

What is this clinical trial studying?

A study testing Fast-CL and Regular-CL in people with Type 1 Diabetes Mellitus, run by University of Ljubljana, Faculty of Medicine at 1 site in Slovenia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Nov 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Slovenia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Time within range 3.9 - 10 mmol/l (70 - 180 mg/dl) (time frame: 28 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03212950, which also lists 28 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2017.
