Glimepiride & metformin FDC along with metformin + dapagliflozin + sitagliptin FDC in T2DM patients with high-risk CKD -Indian real world evidence study: GRACE CKD
摘要
Achieving glycemic control while preserving renal function is critical in patients with type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD). Fixed-dose combinations (FDCs) may improve efficacy, tolerability, and adherence.
ObjectiveThis real-world study evaluated the effectiveness and safety of dual FDC (Glimepiride + Metformin) and triple FDC (Metformin + SGLT2i + DPP4i) in Indian adults with T2DM and CKD.
MethodsMulticentre, retrospective chart review with prospective follow-up and physician survey across 150 centres. Adults with T2DM and CKD (KDIGO G1–G3b with kidney damage or eGFR < 60 mL/min/1.73 m2 and/or UACR ≥ 30 mg/g) receiving either FDC were included. The primary endpoint was change in HbA1c; secondary endpoints were changes in renal biomarkers (creatinine, UACR), electrolytes, weight, adverse events, and physician-reported outcomes.
ResultsAmong 549 patients (mean age 58.6 years), mean HbA1c decreased from 9.39% to 7.45% (Δ –1.94%, 95% CI –2.07 to –1.81; p < 0.0001). The proportion achieving HbA1c < 7% rose from 0% to 38.4%. Mean fasting glucose decreased by 53.6 mg/dL and postprandial glucose by 99.2 mg/dL (p < 0.0001). Serum creatinine declined from 4.11 to 2.58 mg/dL (Δ –1.53 mg/dL; p < 0.0001), and mean UACR from 465 to 272 mg/g (Δ –193 mg/g; p < 0.001). Electrolyte abnormalities improved (hypernatremia 80% → 36%; hypercalcemia 76% → 25%; hyperkalemia 82% → 30%). Weight changes occurred in 49%. Dose titration was required in 31.9%, mainly for renal or lipid parameters. Adverse events (< 10%) included volume depletion (n = 23), nocturia/genitourinary infections (n = 12), ketonuria (n = 5), and pyuria (n = 2); none required hospitalization. Physicians reported improved efficacy and adherence in ~ 80–90% of patients, with 43% showing total compliance. Prescribing rationale included reducing CKD events (83.1%), glycemic control (66.3%), adherence (61.7%), and slowing renal decline (57%).
ConclusionDual and triple FDCs demonstrated effectiveness and tolerability in improving both glycemic and renal outcomes in T2DM patients with CKD, supported by real-world physician feedback.
