The study found that Japanese type 2 diabetes patients treated with basal-bolus insulin therapy showed low baseline hypoglycemia time and achieved improved glycemic control and treatment satisfaction through the use of the FreeStyle Libre device.
Aims/Introduction We investigated the effect of FreeStyle Libre(TM)on glycemic control in Japanese type 2 diabetes patients treated with basal-bolus insulin therapy. Materials and Methods This prospective, 90-day single-arm study enrolled 94 adults with type 2 diabetes treated with insulin. A 14-day masked baseline phase was followed by an 11-week treatment phase during which participants used the device to monitor glucose levels. The primary end-point was time spent in hypoglycemia (<70 mg/dL) for baseline versus study end (days 76-90). Secondary end-points included other measures of glycemic control, along with patient satisfaction using the Japanese Diabetes Treatment and Satisfaction Questionnaire. Results Time spent in hypoglycemia was low at baseline (0.51 +/- 0.93 h/day) and did not significantly decrease at study end (0.47 +/- 0.63 h/day,P = 0.6354). Time in range, time in hyperglycemia and estimated A1c all improved versus baseline (by +1.7 +/- 3.0 h/day, -1.6 +/- .4 h/day and -0.4 +/- 0.8%, respectively,P < 0.0001 in each). Finger stick tests fell from 2.9 +/- 1.3 to 1.9 +/- 1.4/day, and mean scanning frequency during the intervention phase was 11.3/day. The mean treatment satisfaction score increased by 11.8 +/- 5.3 (P < 0.0001). Two severe hypoglycemia-related adverse events were reported; one of which was possibly related to the device. Three participants reported mild device-related skin trauma, site discomfort or subcutaneous bleeding. Conclusions Use of FreeStyle Libre by Japanese type 2 patients diabetes treated with basal-bolus insulin therapy showed a low baseline of hypoglycemia, and enabled improved glycemic control and treatment satisfaction.
