Magnesium Chloride Versus Placebo in Patients Who Have Had a Stroke

May 23, 2012 updated by: Bert Spilker, Relox Medical, LLC

Comparison of Magnesium Chloride Infusions Versus Placebo Administered Concomitantly With 100% Oxygen Given to Patients Who Have Residual Muscle Weakness From a Stroke That Occurred Three Months to Four Years Ago

The purpose of this study is to evaluate the effect of six intravenous (IV) infusions of magnesium chloride versus placebo in patients who have residual muscle weakness from a stroke that occurred three months to four years ago.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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.

Detailed Description

The hypothesis being tested is that these six treatments will improve muscle weakness and lead to an improvement in functioning/activities of daily living as measured by the 100-point Barthel index, three months after their last treatment versus their baseline measure, and that the mean difference between the treatment and placebo groups of patients will be at least three points in this index.

Study Type

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 to 90 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Subjects of either sex above 18 years of age
  2. Documented history of stroke 3 months to four years ago
  3. Subjects may have had two or more strokes
  4. Must have residual muscle weakness with a 25% or greater difference in strength between the right and left sides of the body
  5. Must be assessed as a 2 or 3 on the Modified Rankin Scale
  6. Must have a Barthel score at or below 85

Exclusion Criteria:

  1. Any traumatic brain injury or other brain injury apart from stroke
  2. Renal insufficiency or renal failure
  3. Any medical or physical condition that would interfere with the measurements to be conducted
  4. Any physical therapy in a facility outside their home within three days of screening

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Magnesium infusion in patients breathing 100% oxygen
Patients will be given six infusions over three weeks. Each infusion will last between 4 and 10 minutes. They will then return to clinic in 1,2 and 3 months for the same tests (but no infusions will be given).
Drug: Magnesium Chloride
An infusion of magnesium chloride will be given over 4 to 10 minutes in patients breathing 100% oxygen
Placebo Comparator: Placebo infusion
The patients will receive six placebo infusions after which they will return to clinic at one, two and three months. At the conclusion of the trial those patients who received placebo may elect to receive the active treatment in another (open label) trial that will begin shortly after this one concludes.
Drug: Placebo
A saline placebo will be given as an infusion (six infusions over a three week period) in a double blind manner with the active test agent

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
Barthel Index
Time Frame: Infusions are given over 3 weeks and subjects are followed-up at 1, 2 and 3 month intervals after the infusions
Infusions are given over 3 weeks and subjects are followed-up at 1, 2 and 3 month intervals after the infusions

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
Improvement in muscle strength and function
Time Frame: Infusions are given over 3 weeks and subjects are followed-up at 1, 2 and 3 month intervals after the infusions
Infusions are given over 3 weeks and subjects are followed-up at 1, 2 and 3 month intervals after the infusions
