Can a 15-Day wearable sensor keep blood sugar on target?

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patient age is between 18 and 75 years old. * Patient is clinically diagnosed with diabetes (T1D or T2D), with more than 50% on a stable insulin regimen, defined as no change in the prescribed number of basal insulin administrations per day and less than 10% change in basal total daily insulin dose within 3 months prior to enrollment. Patients not using insulin are considered having a stable treatment regimen if their diabetes management (lifestyle measures and/or non-insulin glucose-lowering medications) has remained unchanged within 3 months prior to enrollment and no treatment intensification is anticipated during the blinded phase. * Patient has a HbA1c of \>7.5%. * Patient and investigator signed and dated the informed consent form prior to first sensor placement. Exclusion Criteria: * Use of any type of rtCGM within 3 months prior to study entry. * Severe hypoglycemia requiring assistance from another individual within the last 12 months, or seizure or loss of consciousness within the last 3 years. * Severe hyperglycemia, that required hospitalization within the last 6 months. * More than one diabetic ketoacidosis (DKA) event in the past year. * History of seizures other than due to hypoglycemia. * Myocardial infarction or stroke within the past 6 month. * Estimated glomerular filtration rate (eGFR) \< 30 mL/min obtained within the prior 12 months as part of usual care, or kidney transplant. * Requirement to undergo magnetic resonance imaging (MRI) during the study period. * Most recent thyroid function test results abnormal, obtained as part of usual care within the prior 2 years. * Presence of a significant medical or psychiatric disorder, or use of a medication that, in the judgment of the investigator, will affect the wearing of sensors, completion of any aspect of the protocol, or increase risk. * Cognitive difficulties that, in the judgment of the investigator, could impair the individual's ability to follow the protocol or increase risk. * Inpatient psychiatric treatment within the past 6 months. * Currently pregnant, lactating, or planning to become pregnant during the study period (within the past 1 month). * Deemed unsuitable by investigators due to any condition that impacts the reliability of HbA1c measurement. * Patient is unable / unwilling to provide informed consent. * Patient is unable to comply with the protocol or proposed follow-up visits. * Patient who is currently enrolled in another clinical study, or has recently participated in a clinical study, that could potentially interfere with the outcomes or introduce bias into the results of the current study (as determined by the investigator). This includes studies involving investigational drugs, medical devices, or other interventions that could impact the safety, efficacy, or scientific integrity of this study.
