Patients with T2D inadequately controlled by metformin require additional oral antidiabetes agent(s), injected GLP-1 or basal insulin. Although insulin has greater effect on A1C than a DPP-4 or SGLT2 inhibitor, its higher rates of hypoglycemia, weight gain and regimen burden might decrease satisfaction and quality of life. We analyzed patient-reported outcomes (PRO) from patients with T2D inadequately controlled by metformin ± sulfonylurea during an international, randomized, 24-week, open-label, non-inferiority trial (NCT02551874) of dapagliflozin plus saxagliptin add-on (DAPA + SAXA, n = 324) compared to titrated insulin glargine add-on (INS, n = 319). A1C and PRO questionnaires were obtained at baseline and weeks 12 and 24. Baseline data were: 54.0% male; 80.4% white; 60.7% working ≥3 days/week; age 55.5 ± 9.6 years; A1C 9.0 ± 1.0%; BMI 32.2 ± 5.3 kg/m2; diabetes duration 9.4 ± 6.3 years. Overall Satisfaction, Regimen Acceptance and its eight subscales, Net Benefit and Preference subscale, and Weight Concern all favored DAPA + SAXA at week 24 (Table). Quality of life scales favored DAPA + SAXA at week 12, but were not different at week 24. Compared to INS, DAPA + SAXA had greater treatment satisfaction and acceptance, better short-term quality of life, and less burden and concern about weight gain, hypoglycemia and pain despite comparable A1C.
