Study summary

This study evaluates the use of the FD2 automated closed loop insulin administration in Adolescents with a poor metabolic control . All youth will be treated in a random order by their usual pump treatment or an Automated system and we will evaluate whether this has an impact on metabolic control and sleep

Read the detailed description

Achievement of a good metabolic control is very important for all persons with diabetes . In adolescence many changes occur , physically , socially and psychologically .This may influence the metabolic control . This study will evaluate whether the automated closed-loop will facilitate and improve the management of diabetes in youth with a poor metabolic control.

It is a single-centre, randomised, two-period crossover study to assess the efficacy /safety and acceptability of the automated closed-loop glucose control (CL) day and night, over 28 days in comparison with continuous subcutaneous insulin infusion (CSII) in the home setting in poorly controlled type 1 diabetes adolescents.

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

12- 18 years Type 1 diabetes according to WHO/ISPAD , for at least 1 year CSII treatment for at least 6 month ≥ 8,0%, for more than 6 months of the patient and parents

Exclusion criteria

Exclusion Criteria:

Non-type 1 diabetes mellitus including those secondary to chronic disease Any other physical or psychological disease or condition likely to interfere with the normal conduct of the study and interpretation of the study results as judged by the investigator.

Current treatment with drugs known to have significant interference with glucose metabolism, such as systemic , as judged by the investigator Known or suspected allergy against insulin Recurrent incidents of severe hypoglycaemia as defined by ISPAD guidelines during the previous 12 months.

More than one episode of diabetic ketoacidosis (DKA) as defined by ISPAD in preceding 12 months

-

Terms in these criteria, in plain language(3)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jul 2017 to primary completion in Jul 2018, 12 months.

Of 845 non-industry interventional studies with no phase under Diabetes Mellitus, Type 1, half reached primary completion within 19 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 38. This study's 12 months is below that.

Counting every sponsor, half of 950 studies reached it within 18 months; a quarter within 9 and three quarters within 35.

How these figures are worked out, and which studies are left out of them.

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 Jul 31, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
