About this study

Single centre, double-blind, randomised, placebo-controlled study of three dosage regimens of Etamicastat (BIA 5-453) in 3 groups of 8 hypertensive patients.

In each group, the study consisted of a 10-day multiple-dose period. Progression to the next dose level only occurred if the previous dose level was considered to be safe and well tolerated. An appropriate interval separated the investigation of doses to permit a timely review and evaluation of safety data prior to proceeding to a higher dose level.

Inclusion criteria

  • Male patients aged between 18 and 65 years (inclusive)
  • Body mass index (BMI) between 18 and 35 kg/m2 (inclusive)
  • Patients with essential hypertension, without previous treatment (but in which treatment was justified), defined at the selection visit as blood pressure (BP) after 10 minutes of rest in supine position of
  • diastolic blood pressure (DBP) ≥ 90 mmHg and/or,
  • systolic blood pressure (SBP) ≥ 140 mmHg
  • Patients with essential hypertension, with previous treatment, defined at the end of the screening period (i.e. after 3 weeks wash-out of antihypertensive treatment(s) and before D-1) as blood pressure (BP) after 10 minutes of rest in supine position of
  • diastolic blood pressure (DBP) ≥ 90 mmHg and/or,
  • systolic blood pressure (SBP) ≥ 140 mmHg
  • Naive or patients taking any class of antihypertensive treatment including (but not limited to) one of the following authorised treatments: B-blockers, diuretics, angiotensin-converting enzyme inhibitor (ACEI), angiotensin receptor blocker (ARB), calcium channel blockers.
