24 Week Efficacy and Safety Study of Empagliflozin (BI 10773) in Hypertensive Black/African American Patients With Type 2 Diabetes Mellitus and Hypertension

Completed · Phase 3 · Has a placebo group

Conditions studied: Diabetes Mellitus, Type 2, Hypertension

In brief

This trial is designed to investigate the efficacy and safety of empagliflozin compared with placebo in hypertensive black/African Americans with type 2 Diabetes Mellitus. Since hyperglycaemia and hypertension are key risk factors for both micro- and macrovascular complications, assessment of both glucose and BP lowering effects of empagliflozin in hypertensive African American patients with type 2 Diabetes Mellitus could provide clinically highly relevant, new information for the use of empagliflozin. Essential hypertension is four times more common in African Americans than in Caucasians. One of the risk factors for hypertension is sodium sensitivity and approximately one third of the essential hypertensive population is responsive to sodium intake. There is a higher association of hypertension with sodium sensitivity in African American patients with type 2 Diabetes Mellitus. The treatment duration of this trial (24 weeks) will enable assessment of the clinically relevant endpoint of a decrease in HbA1c, a well accepted measurement of chronic glycaemic control and the key secondary endpoints of decreases in systolic BP (SBP) and diastolic BP (DBP) at 12 and 24 weeks.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Diagnosis of Type 2 Diabetes Mellitus (T2DM) prior to informed consent.
• Male and female black/African American patients on diet and exercise regimen who are EITHER drug-naïve (defined as absence of any oral antidiabetic therapy, glucagon like peptide-1 (GLP-1) analog or insulin for 12 weeks, 16 weeks for pioglitazone prior to randomisation) OR pre-treated with stable dose of
• Metformin only, or
• Sulfonylurea only, or
• Dipeptidyl peptidase-4 (DPP-4) inhibitor only, or
• metformin plus sulfonylurea, or
• metformin plus DPP-4 inhibitor. Treatment has to be unchanged for a minimum of 12 weeks prior to randomization. Dose for metformin: maximum tolerated dose The maximum daily dose of Sulfonylurea (SU) or DPP-4 inhibitor should not exceed that stated in the local label.
• HbA1c of >= 7.0% (53 mmol/mol) and ≤ 11.0% (97 mmol/mol) at Visit 1 (screening).
• Mean seated Systolic Blood Pressure (SBP) 140-180 mmHg at Visit 1 (screening).
• Successful completion of baseline Ambulatory Blood Pressure Monitor (ABPM) testing with a mean SBP 135-175 mmHg prior to randomisation.
• Treatment with stable doses of at least one but not more than 4 antihypertensive medication >= 4 weeks prior to randomisation.
• Age >= 18 years at Visit 1 (screening)
• Signed and dated written informed consent by date of Visit 1 in accordance with Good Clinical Practice (GCP) and local legislation

You may not qualify if…

• Uncontrolled hyperglycemia with a glucose level >270 mg/dl (>15.0 mmol/L) after an overnight fast during placebo run-in (includes Visit 2.1) and confirmed by a second measurement (not on the same day).
• Exposure to any other antidiabetic medication within 12 weeks prior to randomisation other than metformin, sulfonylurea, Dipeptidyl peptidase-4 (DPP-4) inhibitor, metformin plus sulfonylurea or metformin plus DPP-4 inhibitor.
• Current hypertension treatment with oral Minoxidil (topical minoxidil for hair growth is allowed).
• Mean seated Systolic Blood Pressure (SBP) ≥181 mmHg during placebo run-in visit and confirmed by a second measurement (not on the same day) preferably within one day.
• Upper arm circumference that exceeds the upper circumference level of the cuff size of either Ambulatory Blood Pressure Monitor (ABPM) and/or (BP) measurement device used in the study.
• Night shift workers who routinely sleep during the daytime and/or whose work hours include midnight.
• Diagnosis of autoimmune diabetes/Type I diabetes mellitus, monogenic (neonatal or maturity onset diabetes of the young (MODY)) diabetes or Type I diabetes in adults/latent autoimmune diabetes of adults (LADA) per investigator or patient medical history at the time of Visit 1 (screening).
• Known or suspected secondary hypertension (e.g. renal artery stenosis,phaeochromocytoma, Cushing's disease).
• History or evidence of hypertensive retinopathy (Keith-Wagener grade III or IV) and/or hypertensive encephalopathy.
• Clinically significant valvular heart disease or severe aortic stenosis in the opinion of the investigator.
• Acute coronary syndrome (non- ST wave elevated myocardial infarction (STEMI), STEMI and unstable angina pectoris), stroke or transient ischemic attack within 3 months prior to informed consent.
• Indication of liver disease, defined by serum levels of either Alanine Aminotransferase (ALT) (Serum Glutamic Pyruvate Transaminase(SGPT)), Aspartate Aminotransferase (AST) (Serum Glutamic Oxaloacetic Transaminase (SGOT)), or alkaline phosphatase above 3 x upper limit of normal (ULN) as determined during screening and/or run-in phase.
• Impaired renal function, defined as Estimated Glomerular Filtration Rate (eGFR)< 45 ml/min/1.73m2 (moderate renal impairment, chronic kidney disease epidemiology collaboration Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula) as determined during screening and/or run-in phase.
• Bariatric surgery within the past two years and other gastrointestinal surgeries that induce chronic malabsorption.
• Medical history of cancer (except for basal cell carcinoma) and/or treatment for cancer within the last 5 years.
• Blood dyscrasias or any disorders causing hemolysis or unstable Red Blood Cells (e.g. malaria, babesiosis, haemolytic anaemia, thalassemia, sickle cell anaemia (sickle cell trait is allowed)).
• Medical history and signs and symptoms of diabetic autonomic neuropathy.
• Treatment with anti-obesity drugs 3 months prior to randomisation (i.e. surgery, aggressive diet regimen, etc.) leading to unstable body weight.
