Patient engagement impacts glycemic management with vildagliptin and vildagliptin/metformin (single pill) regimens in type 2 diabetes mellitus (the GLORIOUS study).

AIMS: To evaluate the real-world effectiveness of vildagliptin and vildagliptin/metformin, combined with patient engagement, on glycemic outcomes. Patient engagement included both clinicians' engaging patients through education and counseling; and patients' self-engagement through disease awareness, lifestyle changes, and medication adherence.

METHODS

Prospective, observational, open-label, multi-center, pharmacoepidemiologic study of type 2 diabetes mellitus (T2DM) patients treated de novo with vildagliptin or vildagliptin/metformin. Data were collected at baseline (treatment initiation), 105±15d, and ≥145d.

RESULTS

The evaluable sample included 896 mainly male (58%), overweight (mean±SD BMI=30.3±5.4kg/m2), in later middle age (mean±SD age=64±11years) patients. Over the three visits, mean(±SD) HbA1c levels declined from 8.1%(±1.0) to 7.3%(±1.0) to 7.2%(±0.9); HbA1c control rates rose from 7% to 36% to 43%. Mean±SD FPG levels decreased from 170(±49) to 141(±41) to 139(±42)mg/dL; control rates increased from 12% to 39% to 43% (all p<0.0001). Weight decreased nominally by 2kg (p=0.0290) and BMI by 0.8kg/m2 (p<0.0001). Modeling showed patient engagement activities by clinicians and by patients to be major determinants of glycemic outcomes. No unknown safety signals were detected.

CONCLUSIONS

Vildagliptin and vildagliptin/metformin are effective and safe oral agents in the management of T2DM, especially if part of a treatment program with active patient engagement by clinicians and empowered patients.
