Participant flow
Recruitment details
After screening, patients who were pre-treated with insulin and 1 oral antidiabetic drug (OAD) underwent a 10-week wash-out period. Then patients proceeded to a 2-week open-label placebo run-in period. Patients who were pre-treated with insulin alone skipped the wash-out period and proceeded to an open-label placebo run-in period.
Pre-assignment details
Patients who successfully completed the periods and who still satisfied the inclusion/exclusion criteria were randomised to the 52-week double- blind treatment period of the study in which they received either 1 of the 2 doses of empagliflozin or placebo in addition to insulin.

Outcome results
Change From Baseline in Glycosylated Haemoglobin A1c (HbA1c) After 16 Weeks of Treatment.
The primary endpoint was the change from baseline in HbA1c after 16 weeks of treatment. The term baseline refers to the last observation prior to the administration of any randomised study drug. Means presented are the adjusted means.
Time frame: Baseline and 16 weeks
Population: Full analysis set (FAS) with last observation carried forward at 16 weeks (LOCF)-16; The FAS consisted of all patients in the TS who had a baseline measurement of the primary endpoint.

Percentage of Patients With Investigator Defined Drug-Related Adverse Events (AEs)
Percentage of patients with investigator defined drug-related Adverse Events (AEs) are presented
Time frame: From 1st intake of study drug to last intake of study drug + 7 days; up to 53 weeks
Population: Treated set (TS): TS consisted of all randomised patients who were treated with at least 1 dose of the study drug during the 52-week double blind treatment period. The TS was the basis for safety analyses.
