Study summary

This study aims to analyse if intensive systematic treatment via internet and telephone during 4 months improved HbA1c for persons with type 1 diabetes which are already treated with CGM or FGM, and if the effect continuous for 1-2 years after the intervention stops. Time in Hypoglycaemia, treatment satisfaction, Diabetes distress and hypoglycaemia fear will even be analysed.

A randomised, non-blinded, multi-centre, clinical study for persons with type 1 diabetes and hbA1c ≥ 58mmol/mol and treated with CGM or FGM.

The control group continuous its normal diabetes care with study visits at randomisation, 10, 18, 32, and 52 weeks for HbA1c and to fill in questionnaires.

The intervention group will have contact with the study team on a weekly basis, when mean blood glucose levels the previous week are elevated. They will receive help with analysing data and advice on how to improve their glucose values. They will even meet the study team at randomisation, 10, 18, 32, and 52 weeks for HbA1c and to fill in questionnaires.

Inclusion criteria

  • obtained before trial-related activities (i.e., any activity that would not have been performed during routine patient management)
  • Clinical diagnosis of Type 1 diabetes
  • Adult patients over 18 years of age
  • ≥ 58 mmol/mol
  • Currently using CGM or FGM
  • To have a possibility to download and share FGM/CGM data

Exclusion criteria

Exclusion Criteria:

  • Type 2 diabetes
  • Diabetes duration \<1 year
  • Long-term Systemic treatment during the last 3 months
  • Planned or changed treatment the last 3 months regarding MDI vs. Insulin pump or added or stopped CGM or FGM therapy
  • Current or planned pregnancy or breastfeeding during the next 12 months
  • Planned move during the next 12 months making it not possible to participate in study activities
  • Other reason determined by the investigator not being appropriate for participation
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.

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.

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.

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 Nov 2018 to primary completion in Dec 2023, 61 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 61 months is above 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 Apr 18, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
