Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 2 to less than 6 years who have been prescribed the Control-IQ 1.5 system and have self-reported type 1 diabetes.

Probably not a fit

Patients who do not have type 1 diabetes or are older than 6 years will not benefit from this study.

What this trial studies

This observational study aims to collect safety data on Control-IQ technology version 1.5 in children aged 2 to less than 6 years with type 1 diabetes. Participants will use the Control-IQ system for 12 months in a real-world setting, with a target of at least 120 participants completing the study. The primary focus is on monitoring the risk of diabetic ketoacidosis (DKA) and severe hypoglycemia (SH), while secondary outcomes include continuous glucose monitoring (CGM) time in range and patient-reported outcomes. The study is decentralized, allowing for a broad recruitment of participants across the United States.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the safety and effectiveness of Control-IQ technology for managing type 1 diabetes in young children.

How similar studies have gone: While this study is focused on a specific age group and technology, similar studies on diabetes management technologies have shown promising results in improving patient outcomes.
