Clinical Trial Summary

The purpose of this study was to characterise the plasma and urine pharmacokinetic profile of Etamicastat (BIA 5-453) and its metabolites after three multiple rising dose regimens of Etamicastat (BIA 5-453).

Description:

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.

2. Male patients aged between 18 and 65 years (inclusive)

3. Body mass index (BMI) between 18 and 35 kg/m2 (inclusive)

4. 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

5. 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

6. 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.

10. Presence or history of clinically relevant cardiovascular, pulmonary, gastrointestinal, hepatic, renal, metabolic, haematological, neurological or psychiatric disease.

15. Participation in a drug trial within 3 months preceding the selection visit.

16. Positive result from the hepatitis serology for hepatitis B (HBs Ag) and/or hepatitis C (HCV Ab).

17. Positive result for HIV1+2 serology.

18. Positive Urine Drug Screen (UDS) (amphetamines, benzodiazepines, ecstasy, cocaine, opiates).

19. Loss of greater than 400 mL or blood donation within the last 3 months.

Criteria associated with concomitant diseases:

20. Patients taking one of the following treatments: aldosterone antagonists, nitrite derivatives.

21. Presence or history of any allergic or unusual reaction to drugs.

22. Excessive consumption of beverages containing xanthine bases (more than six cups or glasses per day) or inability to stop consumption during the hospitalization.
