Efficacy and Safety of Azilsartan Medoxomil Used in Combination With Metformin in Participants With Hypertension and Diabetes

20 апреля 2015 г. обновлено: Takeda

A Randomized, Double-Blind, Phase 3b Proof-of-Concept Study to Evaluate the Efficacy and Safety of TAK-491 Compared to Placebo When Used in Combination With Metformin in Subjects With Hypertension and Type 2 Diabetes

The purpose of this study was to evaluate the antihypertensive and antiglycemic effects, as well as the safety and tolerability of TAK-491 (azilsartan medoxomil), once daily (QD), in stage 1 hypertensive, type 2 diabetes mellitus (T2DM) participants whose glycemic control was inadequate on metformin alone.

Подробное описание

The study included a Screening Period of up to 4 weeks, which coincided with a 2-week single-blind, placebo Run-in Period, a 24 week Treatment Period, and a 2-week Follow-up Period. The duration of the study was approximately 30 weeks. The planned number of participants (n=450) was not reached; actual enrollment consisted of 105 particpants. Due to low enrollment this study was terminated early by Takeda.

  5. Had clinical laboratory evaluations (including clinical chemistry, hematology, and complete urinalysis) within the reference range for the testing laboratory or results that were deemed not clinically significant in this participant population for inclusion in this study, by the investigator.

Exclusion Criteria:

  1. Had a mean, trough, sitting clinic diastolic blood pressure (DBP) ≥ 100 mm Hg at Day -1.
  2. Had type 1 or poorly controlled type 2 diabetes mellitus (HbA1c >9.5%) at Screening.
  3. Was taking or expected to take an excluded medication.
  4. Had a history of myocardial infarction, heart failure, unstable angina, coronary artery bypass graft, percutaneous coronary intervention, hypertensive encephalopathy, cerebrovascular accident, or transient ischemic attack.
  5. Had clinically significant cardiac conduction defects (for example, 3rd degree atrioventricular block, left bundle branch block, sick sinus syndrome, atrial fibrillation).
  6. Had hemodynamically significant left ventricular outflow obstruction due to aortic valvular disease.
  7. Had secondary hypertension of any etiology (e.g., renovascular disease, pheochromocytoma, Cushing's syndrome).
  8. Had renal dysfunction defined as estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 at Screening.
  9. Had albuminuria defined as >200 mg/g at Screening.
  10. Had known or suspected unilateral or bilateral renal artery stenosis.
  11. Had unexplained microhematuria ≥3 RBCs/HPF or macrohematuria at Screening and confirmed on repeat testing.
  12. Treatment with antidiabetic agents (sulfonylureas, glucagon-like peptide-1 (GLP-1) analogues, dipeptidyl peptidase-4 (DPP-4) inhibitors, glinides, thiazolidinediones (TZDs), and/or insulin) other than metformin during the 3 months prior to Screening.
  13. Had hyperkalemia as defined by central laboratory normal reference range at Screening.
