Role of Mobile Technology to Improve Diabetes Care in Adults With Type 1 Diabetes: the REMOTE-T1D Study, a Pilot Study

This is a single-center, prospective, randomized, 'open-label,' investigator initiated pilot study evaluating the role of mobile technology to improve diabetes care in adults with type 1 diabetes (REMOTE-T1D). We hypothesize that the use of mobile technology (iBGStar® technology [iPhone® plus the BGStar®]) will result in improvement in Patient Reported Outcomes (PRO), and Treatment Satisfactions with a possible reductions of glucose excursions, A1c, and severe hypoglycemia as compared to routine clinical care using traditional glucose meter SMBG-Accu-chek®. This study aims to demonstrate the efficacy of these technologies in a clinical setting with a hope to improve outcomes and health care cost savings.

The study will enroll 100 patients from the Barbara Davis Center Adult clinic over the age of 18 years who will be randomized in a 1:1 fashion to intervention group using mobile technology (iBG Star) vs. continued routine clinical care (control) using SMBG-Accu-chek meter. All subjects will be followed for study visits with similar frequency at baseline, 1-week, 1-month, 3-months, and 6-months and wear a continuous glucose monitor (CGM) using a DexCom SEVEN Plus® system in a blinded mode for 7 days at baseline (wk0), 1mo, 3mo, and 6mo.

Laboratory analysis for A1c will be performed at baseline, 1-month 3-months, and 6-months. Routine blood tests will be performed in all subjects at baseline, 3months, and 6-months. Blinded CGM data will be analyzed for mean blood glucose values, time spent in hyperglycemic (>240, >300mg/dl) and hypoglycemic (<50, <70, <80 mg/dl) ranges and various indices of glycemic variability.

Inclusion criteria

• Subjects that meet the following criteria will be considered for admission to the study:

• Signed informed consent before any study-related activities
• Male or female aged 18 years and older T1D duration >1 year
• A1c <10%
• Willingness to routinely practice at least 3-7 blood glucose measurements per day
• Ability and willingness to adhere to the protocol including scheduled study visits and blinded CGM wear intermittently) for 6 months. During the weeks of blinded CGM wear, subjects will not be able to use their own real-time CGMs (if they own it)
• Able to speak, read and write English

Exclusion criteria

• Subjects will be excluded from the study if any of the following apply:

• Pregnant or intention to become pregnant during the course of the study
• Severe unexplained hypoglycemia requiring emergency treatment in the previous 6 months
• Use of systemic or inhaled corticosteroids
• History of hemoglobinopathies
• Diagnosis of anemia
• History of pancreatitis
• Extensive skin changes/diseases that inhibit wearing a sensor on normal skin
• Known allergy to adhesives
• Current participation in another investigational study protocol. Must have completed a previous study at least 30 days prior to enrollment.
• Any other condition, as determined by the investigator, which could make the subject unsuitable for the trial, impairs the subject's suitability for the trial, or impairs the validity of the informed consent
• Subjects will not be allowed to use real-time CGM during the blinded CGM wear week.
