Brief Summary

The main objective of the REACTIVATE study is to investigate whether a period of intensive insulin therapy using closed-loop technology, when combined with diet and lifestyle education, can restore beta-cell function and achieve remission of recent-onset type 2 diabetes. This is a single-centre, open-label, randomised, parallel design study comparing up to 12 weeks of fully closed-loop insulin delivery to standard care with a glucose sensor in adults with recent-onset type 2 diabetes. The primary outcome is the number of participants achieving remission of diabetes at 52 weeks, defined as HbA1c below 48mmol/mol after 12 or more weeks off all diabetes medications. Other key outcomes include area under the curve for C-peptide and glucose during mixed meal tolerance test, the proportion of time spent with glucose levels within and above the target glucose range and mean sensor glucose as recorded by glucose sensor at 52 weeks. Safety evaluation comprises severe hypoglycaemic episodes, and other adverse and serious adverse events. Utility and human factors outcomes include glucose sensor and closed-loop usage, questionnaires and semi-structured interviews.
