Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Genders Eligible for Study

Description

Inclusion Criteria:

  • Age 18 or over
  • Hypertensive at screening: Diastolic blood pressure (DBP) 95 - 115 mm Hg and / or systolic blood pressure (SBP) >= 160 mm Hg on no therapy or on monotherapy. If currently on monotherapy, DBP could have been < 95 mm Hg and SBP < 160 mm Hg, but the patient must have been experiencing unacceptable side effects from their current treatment. Patient must then be able to stop treatment for the placebo run in phase of four weeks without endangering their health (at investigator's discretion)
  • Hypertensive at randomisation: DBP 95-115 mm Hg and or SBP >=160
  • Able to give written informed consent

Exclusion Criteria:

  • Grad III or grad IV hypertensive retinopathy
  • Renal impairment; serum creatinine > 150 µmol/L
  • Heart failure. (New York Heart Association (NYHA) Class III or IV)
  • Liver impairment (abnormal Liver function test (LFT) with aspartate-amino transferase (AST) / alanine-amino transferase (ALT) > 2x upper normal limit or bilirubin > 2x upper normal limit)
  • Recent (< 2 months) history of unstable angina
  • Recent (< 2 months) history of myocardial infarction
  • Recent (< 2 months) history of stroke
  • History of diabetes mellitus or impaired glucose tolerance or random blood glucose >= 9 mMol/L
  • Any acute systemic illness or infection
  • Any severe disease which could interfere with survival or well-being during the study (e.g. malignancy)
  • Patients of child bearing potential
  • Current or previous drug and / or alcohol abuse
  • Severely limited venous access
  • Haemoglobin < 10g/dL (male patients), haemoglobin < 9g/dL (female patients)
  • Requirement for anticoagulant therapy
  • Severe valvular heart disease (investigator's discretion)
  • Atrial fibrillation or other serious cardiac dysrhythmia
  • History of thyroid disease or abnormal thyroid function test (thyroid stimulating hormone (TSH) < 0.4 mU/L or > 5.4 mU/L)
  • History of connective tissue disorder
  • Concurrent participation in any other clinical trial or participation within two months enrolment
  • Requirement for restricted drugs
  • Patients currently on treatment with lacidipine or bendrofluazide (BNFZ)
  • Patients unable to attend clinics
  • Any clinical condition which in the opinion of the investigator, would preclude the safe fulfillment of the protocol and the safe administration of trial medication
  • Seated blood pressure (BP) exceeding either 210 mm Hg (systolic) or 115 mm Hg (diastolic) at screening or randomization
  • Standing BP < 140 mm Hg (systolic) and < 95 mm Hg (diastolic) at randomization

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Changes in ß-TG (thromboglobulin)
Time Frame: Up to week 12 after drug administration
Up to week 12 after drug administration

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Changes in soluble p-selectin
Time Frame: Up to week 12 after drug administration
Up to week 12 after drug administration
Changes in rheological factors

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
December 1, 1997

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
