Efficacy and Safety of Valsartan/Hydrochlorothiazide Combination Compared to Valsartan Monotherapy or Hydrochlorothiazide Monotherapy in Elderly (>70) With Mild-moderate Hypertension.

April 15, 2011 updated by: Novartis Pharmaceuticals

A 16 Week Multi-center, Randomized, Double-blind Study to Evaluate Efficacy and Safety of Valsartan/Hydrochlorothiazide (HCTZ) Combination Therapy Compared to Patients Initiated With Valsartan Monotherapy or Hydrochlorothiazide (HCTZ) Monotherapy in Very Elderly Patients With Essential Hypertension

The purpose of the study is to evaluate the safety and efficacy of initial treatment therapy with valsartan/hydrochlorothiazide (HCTZ) versus the initial treatment therapy with monotherapies (valsartan or HCTZ) in the very elderly patients (greater than or equal to 70 years) with stage 1 or 2 hypertension

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.

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

70 years and older (Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  • Age 70 years or older.
  • Patients with hypertension prior to being randomized into study.
  • Patients must have an office cuff MSSBP ≥ 140 and ≤ 200 mmHg systolic.
  • Have the ability to communicate and comply with all study requirements.
  • Provide written informed consent to participate in the study prior to any screening or study procedures.

Exclusion Criteria:

  • Use of other investigational drugs within 30 days of enrollment.
  • History of hypersensitivity to any of the study drugs or to drugs of similar chemical classes.

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.
