A Study to Test How Well Empagliflozin Works in Chinese Patients With Type 2 Diabetes Who Already Take Insulin
- Registration Number
- NCT04233801
- Lead Sponsor
- Boehringer Ingelheim
- Brief Summary
This is a study in Chinese adults with type 2 diabetes. The study is open to people who take insulin but still have too high blood sugar levels. Participants may additionally be taking up to 2 other medicines for their diabetes. The purpose of this study is to find out whether empagliflozin taken together with insulin helps people with type 2 diabetes to better control their blood sugar.
The participants are in the study for about 7 months. During this time, they visit the study site about 8 times, 1 additional visit may be either a visit to the study site or a phone call. At the start of the study, participants are put into 3 groups by chance. Participants get either 10 mg empagliflozin tablets, or 25 mg empagliflozin tablets, or placebo tablets once a day. Placebo tablets look like empagliflozin tablets but do not contain any medicine.
The doctors regularly take blood samples from the participants. The changes in blood sugar levels are compared between the groups. The doctors also check the general health of the participants.

Acceptable basal insulins should have duration of action up to 24 h such as insulin Degludec, insulin glargin, insulin detemir or NPH (neutral protamine hagedorn) insulin; Acceptable pre-mixed insulins could be once or twice daily posology only. The total insulin dose should not be changed by more than 20% of the baseline value within the 12 weeks prior to randomisation (Visit 3). Both human insulin & insulin analogue are acceptable;
- If the patient is taking OADs, regimen has to be unchanged for at least 12 weeks prior to randomization (Visit 3);
- If the patient is taking metformin, stable dose (at least 1500 mg daily or maximum tolerated dose) must be maintained for at least 12 weeks without dose adjustments prior to randomization (Visit 3);

Women of childbearing potential (WOCBP) must be ready and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. A list of contraception methods meeting these criteria is provided in the patient information.

Group Intervention Description Placebo Placebo Matching placebo was administered orally once daily for a treatment period of 24 weeks. Before the first dose of randomised drug, all participants went through a 2-week open label placebo run-in period, taking Placebo tablets orally once daily. Empagliflozin 10 mg Empagliflozin 1 table of 10 milligrams (mg) of Empagliflozin was administered orally once daily for a treatment period of 24 weeks. Before the first dose of randomised drug, all participants went through a 2-week open label placebo run-in period, taking Placebo tablets orally once daily. Empagliflozin 25 mg Empagliflozin 1 table of 25 milligrams (mg) of Empagliflozin was administered orally once daily for a treatment period of 24 weeks. Before the first dose of randomised drug, all participants went through a 2-week open label placebo run-in period, taking Placebo tablets orally once daily.
- Primary Outcome Measures
Name Time Method Change From Baseline in Glycosylated Haemoglobin A1c (HbA1c) at Week 24 At baseline (Week 0) and at Week 24 A restricted maximum likelihood (REML) based mixed model repeated measures (MMRM) approach was applied including treatment, background therapy, and visit as fixed classification effects, baseline HbA1c and baseline estimated glomerular filtration rate (eGFR) as the linear covariates, treatment by visit interaction, and baseline HbA1c by visit interaction.
- Secondary Outcome Measures
Name Time Method Percentage of Participants With HbA1c<7.0% at Week 24 At Week 24 Percentage of participants with glycosylated haemoglobin A1c (HbA1c) \<7.0% at Week 24 is reported.
Change in Body Weight From Baseline to Week 24 At baseline (Week 0) and at Week 24 Change in body weight from baseline to Week 24 is reported. A restricted maximum likelihood (REML) based mixed model repeated measures (MMRM) approach was applied including baseline body weight, and its interaction with visit.
Change From Baseline in Systolic Blood Pressure (SBP) at Week 24 At baseline (Week 0) and at Week 24 A restricted maximum likelihood (REML) based mixed model repeated measures (MMRM) approach was applied including baseline SBP and its interaction with visit.
Change From Baseline in Diastolic Blood Pressure (DBP) at Week 24 At baseline (Week 0) and at Week 24 A restricted maximum likelihood (REML) based mixed model repeated measures (MMRM) approach was applied including baseline DBP and its interaction with visit.
Number of Participants With Confirmed Hypoglycaemic Events From first administration of the initial randomised study medication to last intake of study medication + 7 days (inclusive), up to 176 days. Confirmed hypoglycemic events refer to the hypoglycaemic events with a plasma glucose value of ≤70 milligrams per deciliter (mg/dL) or where assistance was required.
Number of Participants With Adjudicated Diabetic Ketoacidosis (DKA) Events From first administration of the initial randomised study medication to last intake of study medication + 7 days (inclusive), up to 176 days. The risk of DKA had to be considered in the event of non-specific symptoms such as nausea, vomiting, anorexia, abdominal pain, excessive thirst, difficulty in breathing, confusion, unusual fatigue or sleepiness. In case of a suspected DKA, the investigator was to ensure that appropriate tests were performed at the earliest opportunity according to 2017 China Type 2 diabetes mellitus (T2DM) guidelines.
An independent external Clinical event committee (CEC) was established to adjudicate centrally and in a blinded fashion events suspected of DKA and certain hepatic events.
DKA was investigated using both broad and narrow Boehringer Ingelheim customised MedDRA query (BIcMQs).Change From Baseline in Fasting Plasma Glucose (FPG) at Week 24 At baseline (Week 0) and at Week 24 A restricted maximum likelihood (REML) based mixed model repeated measures (MMRM) approach was applied including baseline FPG and its interaction with visit.
Change From Baseline in 2-hour Post-prandial Glucose (PPG) at Week 24 At baseline (Week 0) and at Week 24 The Analysis of covariance (ANCOVA) model included treatment and background therapy as classification effects, baseline PPG and baseline Estimated glomerular filtration rate (eGFR) as the linear covariates.
