Diabetes Mellitus, Type 1
Conditions
Brief summary
Placebo-controlled, double blind (triple-dummy technique), randomised parallel design comparison of three oral doses (2.5 mg, 10 mg, and 25 mg) of empagliflozin in patients with T1DM as adjunctive therapy to insulin over 28 days. Patients will undergo a 14-day open-label placebo run-in period before randomisation. Background insulin therapy will be kept stable during the first 7 days of the treatment period and will be freely adjusted thereafter.

Outcome results
Change From Baseline in 24 h UGE (g/24 h) After Seven Days of Treatment With Empagliflozin 2.5 mg, 10 mg, or 25 mg, or Placebo
Change of urinary glucose excretion (UGE) (g/24 h) from baseline (refers to the last measurement prior to the first intake of any randomised trial medication) after seven days of treatment with empagliflozin 2.5 mg, 10 mg, or 25 mg, or placebo. The treatment effect was estimated on the basis of the least square mean treatment difference at Day 7 extracted from the primary analysis model. The primary endpoint is exploratory.
Time frame: baseline (Day -1) and 7 days after first drug administration (Day 7)
Population: Full analysis set (FAS): all patients randomised, treated with at least one dose of study drug, had a baseline UGE (g/24 h) and a UGE (g/24 h) on Day 1 or Day 7.~The last observation carried forward (LOCF) approach was used as the primary method of imputation for missing data.
