Plain English Summary
Background and study aims
Type 2 diabetes (T2D) often requires the use of insulin to keep blood sugar levels under control. Basal insulin-supported oral therapy (BOT) is a clinically valid and useful approach for the management of T2D. BOT is started with active insulin dose titration, which involves self-monitoring of the fasting blood glucose (FBG) and adjusting the dose of the once-daily long-acting (basal) insulin accordingly until target glucose levels are reached. The titration is typically initiated and supervised by a healthcare professional (HCP) and follows the default scheme described by the insulin manufacturer. However, HCPs can deviate from the manufacturer recommendations based on the individual needs of the person with diabetes (PwD). The GetFit short messaging service is a new telemedical approach to basal insulin titration developed by Roche Diabetes Care. After initiation of the GetFit service by an HCP during a patient visit, the service can be used to titrate the user to his/her individual optimum basal insulin dose. The aim of this study is to test the effectiveness of the GetFit supported titration of once-daily long-acting (basal) insulin in patients with T2D.
Who can participate?
Patients with T2D with sub-optimal blood sugar control on non-insulin therapy who are planned to be treated with BOT
What does the study involve?
In the study, titration of once-daily, long-acting insulin will be supported by using the investigational device, the RocheDiabetes InsulinStart service for about 4.5 months (18 weeks). During the study, participants are supported by the GetFit service to titrate to their individual optimal insulin dose for reaching their target FBG level. After 16 weeks the effectiveness of the therapy is evaluated.
What are the possible benefits and risks of participating?
During participation in this study, participants may encounter the known potential risks of the BOT therapy (HbA1c determination, BG measurement, insulin administration). These risks are an integral part of diabetes therapy and applied in daily practice. The participants may experience the following potential benefits while participating in this study. The GetFit service, the BG meter and lancing device including the consumables needed for the study procedures will be provided at no charge to the subjects. Costs for SMS will be compensated. All obligatory study visits (as well as obligatory telephone calls) will be provided at no charge to subjects. Participants may reach their target FBG level more rapidly and/or with less effort. Participants may be more encouraged to perform BOT and to titrate their insulin dose. Participants may reduce their HbA1c, FBG, number of diabetic ketoacidosis (a serious complication of diabetes) or hypoglycemic (low blood sugar) events, and distress with diabetes. Participants may need less help from their physician or diabetes nurse. Participants may gain additional attention from their physician. Participants may be motivated to learn more about diabetes and to have better discussions of potential issues with their health care providers. Participants may gain personal satisfaction from participating in this study.

Condition
Type 2 diabetes mellitus
Intervention
Routine BOT therapy supported by a text messaging service: Patient needs to respond to SMS from the messaging service. In particular, the patient needs to enter Fasting Blood Glucose in the morning and the injected insulin amount in the evening (16 weeks)
Blood collection for determination of HbA1c: twice during the study (baseline and Visit 4 after 16 weeks)
Questionnaires: Patients are asked to complete electronic questionnaires (baseline and Visit 4 after 16 weeks)

Primary outcome measure
The percentage of subjects with FBG stable in their individual target range after completion of GetFit supported basal insulin titration at latest, measured using [method] calculated using system data at Visit 4 (week 16 [±14 days])
Secondary outcome measures
1. Number of days until the FBG target range was reached, calculated using system data, timepoint individual for each patient
2. Change in HbA1c measured using blood sample analysis at Visit 4 compared to baseline (pre-post)
3. HbA1c measured using blood sample analysis at visit 4
4. Change in FBG (blood glucose self-measurement) at Visit 4 compared to baseline (pre-post)
5. Daily basal insulin dose required after reaching the FBG target range, calculated using system data, timepoint individual for each patient
6. Number of hypoglycemic events, i.e., self-monitored BG < 70 mg/dl (3.9 mmol/l) from baseline to visit 4
7. Number of additional contacts (visits and telephone) between subject and HCP and other study staff concerning the use of GetFit and the insulin titration including FBG measurement and insulin administration, calculated from baseline to Visit 4
8. Adherence to the requests of the GetFit service:
8.1. Response rate to the GetFit service, specified by percent of SMS answered by the subject within the expected time between baseline and Visit 4
8.2. Response time from receiving the SMS from the GetFit service to the SMS sent by the subject between baseline and Visit 4
