Results of the Adequacy of glycemiC Control in pAtients with type 2 Diabetes mEllitus treated with Metformin monotherapY at the maximal-tolerated dose (ACCADEMY) study
Abstract
The treatment objective in diabetes is prevention of the onset or progression of complications. Intensive treatment reduces the risk of complications. The aim of the study was to evaluate glycemic control in patients with type 2 diabetes mellitus treated with metformin monotherapy at the maximal-tolerated dose. This retrospective, multicenter, observational study, enrolled patients ≥45-year old receiving metformin as monotherapy for at least 36 months. Data were collected on demographic and disease characteristics, clinical status, lifestyle, comorbidities, and diabetes complications at baseline, 9, 18, and 24 months. Primary study variables were percentage of patients achieving HbA1c <7 % and mean HbA1c reduction after 9 months. Eligible patients (n = 524, mean age 65.9 ± 7.9 years) had a mean age at diagnosis of 57.5 ± 7.9 years. A second antidiabetic drug was added in 24 % of patients (126/524); time to treatment escalation was 44.7 ± 25.1 months. Regarding primary study variables, 61.7 % of patients (322/522) achieved HbA1c of 7.0 % at 9 months, compared to 37.0 % of patients (194/524) at baseline; mean HbA1c was reduced from 7.30 ± 0.95 to 6.84 ± 0.86 % after 9 months. The estimated mean time of exposure above 7 % was 19 months, 15 months for patients ≥65-year old, and 21 months for younger patients. Regression analysis revealed that patients with longer disease duration, and patients <65-year old responded less well to metformin. A substantial number of patients…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 524 participants or records.
