Study summary

This is a staggered randomised controlled trial that aims to assess the impact of an automated insulin delivery (AID) system on glucose, gastrointestinal and patient-reported outcomes.

Read the detailed description

Following a run-in period of 2 weeks, participants will be randomised to control or hybrid automated insulin delivery (AID) using the 780G system and will remain in the intervention phase of the study for 12 weeks (4-week control, then 4-week AID or Control and finally 4-week AID). The total duration for each participant will be 14 weeks. There are 5 study visits (combination of face to face or/and remote) and two telephone visits in total.

What researchers measure

Primary outcomes

  1. Percentage time spent in glucose target (3.9-10mmol/L)

    The change in percentage time in glucose target between baseline and intervention/control

    Time frame: 4 - 8 weeks

Secondary outcomes

  1. Percentage time spent in hypoglycaemia (<3.0mmol/L)

    The change in percentage time in hypoglycaemia(\<3.0mmol/L) between baseline and intervention/control

    Time frame: 4 - 8 weeks

  2. Percentage time spent in hypoglycaemia (<3.9mmol/L)

    The change in percentage time in hypoglycaemia (\<3.9mmol/L) between baseline and intervention/control

    Time frame: 4 - 8 weeks

  3. Percentage time spent in hyperglycaemia (>10mmol/L)

    The change in percentage time in hyperglycaemia (\>10mmol/L) between baseline and intervention/control

    Time frame: 4 - 8 weeks

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

Started Aug 2023 (actual). Primary completion is estimated for Jun 2024, 10 months after the start.

Of 49 non-industry interventional studies with no phase under Gastroparesis, half reached primary completion within 36 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 59. This study's planned 10 months is below that.

Counting every sponsor, half of 58 studies reached it within 25 months; a quarter within 11 and three quarters within 58.

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 Sep 13, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
