The SILVER Study: Systolic Hypertension Interaction With Left Ventricular Remodeling

July 28, 2009 updated by: Synvista Therapeutics, Inc

Systolic and Pulse Pressure Hemodynamic Improvement By Restoring Elasticity: The SILVER Study

The purpose of this study is to evaluate the safety and efficacy of ALT-711 in the treatment of isolated systolic hypertension in a formal study in patients with left ventricular hypertrophy. Eligible patients will be randomized to double-blind treatment once daily for 6 months with oral ALT-711 (210 mg) or placebo.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

50 years and older (Adult, Older Adult)

Description

Inclusion Criteria

  • Men or women at least 50 years of age.
  • Screening diagnosis of isolated systolic hypertension, defined as systolic blood pressure >150 mm Hg and diastolic blood pressure <90 mm Hg (office blood pressure measurements) and systolic blood pressure >140 mm Hg (measured by 24-hour ambulatory blood pressure monitoring-mean daytime values).
  • Baseline systolic blood pressure >150 mm Hg and diastolic blood pressure <90 mm Hg (office blood pressure measurements).
  • Patients with left ventricular hypertrophy (LVH) as determined by limited echocardiography for LVH (i.e., wall thickness > 1.2 cm).
  • Patient can complete an informed consent.

Exclusion Criteria

  • Patient <50 years of age.
  • Patients on antihypertensive therapy with changes in dose in the last 1 month prior to the entry into the study.
  • Hb A1c > 9%.
  • Serum creatinine > 1.7mg/dL.
  • History of ketoacidosis or uncontrolled diabetes within the last 2 years.
  • History of congestive heart failure.
  • History of stroke, or any sequelae of a transient ischemic attack, reversible ischemic neurologic defect, or stroke, within the last 12 months.
  • History of acute myocardial infarction within 6 months prior to entry into the study.
  • Any significant ECG abnormalities, including second degree AV-block or complete AV-block. Any known significant arrhythmia including atrial flutter, ventricular tachycardia, WPW-syndrome. Any hemodynamically significant valvular heart disease.
  • Any significant systemic illnesses or medical condition that could lead to difficulty complying with the protocol.
  • Screening or Baseline liver function tests SGOT and/or SGPT > 2.0 times the upper limits of central laboratory normal range.
  • Use of systemic and/or inhaled corticosteroids (excluding topical corticosteroids).
  • Any additional condition(s), which in the investigator's opinion would prohibit the patient from completing the study, or not be in the best interest of the patient.
  • Use of any investigational drugs within 30 days prior to screening.
  • Previous exposure to ALT-711.
  • Known seropositivity for HIV or hepatitis C, or presence of hepatitis B surface antigen.
  • Pregnancy or active breast-feeding. Female patients of childbearing potential (not postmenopausal for at least 5 years or surgically sterilized) must agree not to become pregnant during the duration of the study. Specifically, they must agree to use an appropriate contraceptive regimen. Acceptable regimens include abstinence, systemic hormones, intrauterine devices and barrier methods, such as cervical caps, male or female condoms, or diaphragms with concomitant intravaginal spermicide. A barrier method must have been used without failure for at least 1 year immediately preceding entry into the study.
  • Positive drug screen.
  • Necessity to use tobacco or nicotine-containing products, or to consume caffeine- containing beverages and/or food, and/or alcohol after midnight prior to clinic visit days, until after any evaluations.

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

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.
August 1, 2001

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
