Adapting Diabetes Treatment Expert Systems to Patient in Type 1 Diabetes

Adapting Diabetes Treatment Expert Systems to Patient's Expectations and Psychobehavioral Characteristics in Type 1 Diabetes

Source: ClinicalTrials.gov · Last updated 28 Oct 2025

Brief summary (registry, in English)

This study is evaluate the superior efficacy of a Continuous Glucose Monitor (CGM)-based advisory system in Type 1 Diabetes Mellitus (T1DM), as compared to Sensor Augmented Mode (SAM) therapy, and with characterizing the impact of psycho-behavioral factors on system performance, which will enable system individualization and lead to automated adaptation of advice delivery to optimize glycemic control and reduce the system's psychological impact.

    • Inpatient psychiatric treatment in the past 6 months
    • Presence of a known adrenal disorder
    • Abnormal liver function test results (Transaminase \>3 times the upper limit of normal)
    • Abnormal renal function test results (calculated GFR \<60 mL/min/1.73m2).
    • Active gastroparesis requiring medical therapy
    • Uncontrolled thyroid disease (TSH undetectable or \>10 mlU/L).
    • Abuse of alcohol or recreational drugs
    • Infectious process not anticipated to be resolved prior to study procedures (e.g. meningitis, pneumonia, osteomyelitis, deep tissue infection).
    • Uncontrolled arterial hypertension (Resting diastolic blood pressure \>100 mmHg and/or systolic blood pressure \>180 mmHg).
    • Uncontrolled microvascular complications such as current active proliferative diabetic retinopathy defined as proliferative retinopathy requiring treatment (e.g. laser therapy or VEGF inhibitor injections) in the past 12 months.

Other

  • NPH (neutral protamine hagedorn) insulin
  • Not familiar with smart phone technology
  • Participation in another pharmaceutical or device trial at the time of enrollment or during the study.
