Abstract:
This 24-week, double-blinded, phase 3 clinical trial (DEPICT-2; ClinicalTrials.gov, NCT02460978) evaluated efficacy and safety of dapagliflozin as adjunct therapy to adjustable insulin in patients with inadequately controlled type 1 diabetes (HbA1c 7.5–10.5%). RESEARCH DESIGN AND METHODS Patients were randomized 1:1:1 to dapagliflozin 5 mg (n = 271), dapagliflozin 10 mg (n = 270), or placebo (n = 272) plus insulin. Insulin dose was adjusted by investigators according to self-monitored glucose readings, local guidance, and individual circumstances. RESULTS Baseline characteristics were balanced between treatment groups. At week 24, dapagliflozin significantly decreased HbA1c (primary outcome; difference vs. placebo: dapagliflozin 5 mg −0.37% [95% CI −0.49, −0.26], dapagliflozin 10 mg –0.42% [−0.53, −0.30] ), total daily insulin dose (−10.78% [−13.73, −7.72] and −11.08% [−14.04, −8.02] , respectively), and body weight (−3.21% [−3.96, −2.45] and −3.74% [−4.49, −2.99] , respectively) (P & lt; 0.0001 for all). Mean interstitial glucose, amplitude of glucose excursion, and percent of readings within target glycemic range ( & gt;70 to ≤180 mg/dL) versus placebo were significantly improved. More patients receiving dapagliflozin achieved a reduction in HbA1c ≥0.5% without severe hypoglycemia compared with placebo. Adverse events were reported for 72.7%, 67.0%, and 63.2% of patients receiving dapagliflozin 5 mg, dapagliflozin 10 mg, and placebo, respectively. Hypoglycemia, including severe hypoglycemia, was balanced between groups. There were more adjudicated definite diabetic ketoacidosis (DKA) events with dapagliflozin: 2.6%, 2.2%, and 0% for dapagliflozin 5 mg, dapagliflozin 10 mg, and placebo, respectively. CONCLUSIONS Dapagliflozin as adjunct therapy to adjustable insulin in patients with type 1 diabetes was well tolerated and improved glycemic control with no increase in hypoglycemia versus placebo but with more DKA events.
