Brief summary: This open-label study aims to evaluate the impact of BI 10773 treatment on glomerular filtration rate under controlled conditions of euglycaemia and hyperglycaemia in subjects with type 1 diabetes mellitus with or without renal hyperfiltration and to characterize the safety and efficacy of BI 10773 25 mg QD as add-on therapy to insulin in these subjects.


Eligibility criteria: Inclusion criteria:

1. Male or female subjects 18 years of age or older diagnosed with type 1 diabetes mellitus
2. Glycated hemoglobin (HbA1C) of 6.5% to 11.0% and an estimated glomerular filtration rate (eGFR) greater or equal to 60 ml/min/1.73m² at screening
3. Subjects must be either experienced insulin pump users or be on multiple daily injections of any type of insulin

Exclusion criteria:

1. Evidence of macroalbuminuria or leukocyte positive urinalysis at screening
2. Any concomitant medication known to interfere with renin-angiotensin-aldosterone system (RAAS) activity or treatment with any other drugs to reduce blood glucose other than insulin
3. History of macrovascular disease or any other disease which would interfere with trial participation or any ongoing clinical condition that would jeopardize subject safety or study compliance based on investigator judgement
