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

A 4 week study with active or placebo medication at randomization and switch treatment at 2-week crossover visit (2 weeks on each arm). There will be a total of 3 visits to the clinic. Subjects will receive instruction on how to apply the DSTG/placebo at the injection site and keep a daily injection site reaction diary.

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

No

Genders Eligible for Study

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
Measure Description
Time Frame
Local Injection Site Reaction (0-6) Scale at Baseline, 2 Weeks
Time Frame: 2 weeks
patients will complete a daily diary rating their reaction for elements including pain and inflammation or no reaction to all 6 elements listed on the local injection site reaction scale. Range of scores is 0-6 with zero best and 6 worst.
2 weeks
Pain Scale at 2 Weeks
Time Frame: 2 weeks
0-10 subjective Likert scale for severity of injection site reaction associated pain. Zero is best and 10 is worst
2 weeks

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
Measure Description
Time Frame
Subject Global Impression at 2 Weeks
Time Frame: 2 weeks
This is a single question: "How would you rate your level of comfort with Copaxone injection during the past two weeks?" Responses include Extremely good, Quite good, Better than average, Average, Below Average, Quite bad, Extremely bad.
