AimTo evaluate the safety and tolerability of dapagliflozin, a highly selective sodium-glucose co-transporter-2 inhibitor, in patients with type 2 diabetes mellitus (T2DM).
MethodsData were pooled from 13 placebo-controlled trials of up to 24weeks' duration (dapagliflozin, n=2360; placebo, n=2295). Larger placebo-/comparator-controlled pools of 21 (208weeks; dapagliflozin, n=5936; control, n=3403) and 30 trials (12weeks; dapagliflozin, n=9195; control, n=4629) assessed the rare adverse events (AEs) of diabetic ketoacidosis (DKA) and lower limb amputation, respectively.
ResultsOver 24weeks, the overall incidence of AEs and serious AEs (SAEs) was similar for dapagliflozin and placebo: 60.0% vs 55.7% and 5.1% vs 5.4%, respectively. Rates of hypoglycaemia, volume depletion AEs, urinary tract infections (UTIs) and fractures were balanced between the groups. Genital infections were more frequent with dapagliflozin (5.5%) vs placebo (0.6%) and renal function AEs occurred in 3.2% vs 1.8% of patients (the most common renal AE was decreased creatinine clearance: 1.1% vs 0.7%). In the 21-study pool, 1 SAE of DKA and 3 AEs of ketonuria/metabolic acidosis occurred with dapagliflozin vs none with control; estimated combined incidence for these events was 0.03% (95% confidence interval 0.010-0.089). In the 30-study pool, lower limb amputation occurred in 8 (0.1%) and 7 (0.2%) patients receiving dapagliflozin and control, respectively.
ConclusionThe overall incidence rates of AEs and SAEs were similar in the dapagliflozin and placebo/control groups, including the incidence of hypoglycaemia, volume depletion, fractures, UTIs, amputations and DKA. Genital infections were more frequent with dapagliflozin than placebo.
