The TANGO study is a 12-month study involving 120 children and adolescents with Type 1 Diabetes (T1D) across the Czech Republic, Israel, and Poland who use automated insulin delivery (AID) systems.
Currently, the global standard for diabetes management is "Time in Range" (TIR), which aims to keep blood sugar levels between 70-180 mg/dL. However, newer technologies like AID systems may now allow for a tighter, more physiological goal called "Time in Normal Glycemia" (TING), which targets a range of 70-140 mg/dL.
This study will randomly assign participants to follow either the standard TIR target or the tighter TING target to see if the narrower range improves overall blood sugar control and HbA1c without increasing the risk of hypoglycemia, family stress, or daily treatment burden.
By comparing these two approaches, researchers hope to determine if clinical guidelines should be updated to reflect a more precise glucose target for children and adolescents worldwide

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
