971-P: Targeting Personalized Glycemic Response Led to Reduction in Glycemic Variability in Fitterfly CGM Diabetes Digital Therapeutics Program

Background and Aim: Glycemic variability (GV) has shown association with higher risk of diabetes-related complications and increased cardiovascular events in people with T2DM. Personalized glycemic response (PGR) refers to differences in postprandial glycemic response between two people after consumption of the same food. Understanding of PGR after meals can help in improving glycemic control. The study aims at assessing the real-world effectiveness of the PGR based Fitterfly Diabetes CGM program to reduce GV among people with T2DM.

Methods: De-identified data of 220 participants (mean age: 48.8 ± 12.8 years, female: 35.9 % (79/220)), enrolled in the Fitterfly Diabetes CGM program was analyzed. CGM access was provided in the first 14 days of the program. In week-1, the users followed their usual lifestyle where blood sugar readings were correlated with meals and other lifestyle data to understand the PGR of each user. A modified lifestyle plan was introduced in week-2 and was followed till the end of the program. Mean blood glucose (mg/dL), TIR, TAR, TBR, glucose management indicator (GMI), and the percentage coefficient of variation for glucose (CV) were analyzed in week-1 and week-2. All data has been represented as median (IQR).

Results: After 7 days, the median mean blood glucose and TAR significantly reduced by -4.3 (-14.8, 3.3) mg/dL (P<.001) and -2.5 (-11.6, 5.2) % (P<.001) from week-1 baseline of 130.4 (104.4, 169.7) mg/dl and 15.1 (2.8, 36.8) % respectively. The median TIR significantly increased by 1.7 (-2.8, 7.0) % from a baseline of 77.7 (57.2, 89.9) % (P=.001). The median GMI and CV was significantly reduced by -0.1 (-0.3, 0.1) % (P<.001) and -0.7 (-3.4, 1.8) % (P=.005) from baseline of 6.4 (5.8, 7.4) % and 26.9 (22.9, 31.9) % respectively. No significant change was observed in median TBR (P=.40).

Conclusion: The study showed significant improvement in glycemic control and GV after 7 days of PGR-based guidance on the Fitterfly Diabetes CGM program.
