Evaluation of Two Glatiramer Acetate (GA) Formulations in Relapsing-Remitting Multiple Sclerosis (RRMS) Patients (ENCORE)

August 8, 2013 updated by: Teva Neuroscience, Inc.

An Open-Label, Multicenter Study Evaluating Patient Injection Satisfaction With Two Formulations of Glatiramer Acetate (GA) Using Autoject 2 as the Subcutaneous Injection Delivery Method.

This is an open-label, multicenter study conducted at approximately 20 sites. Each patient will inject GA daily for 6 weeks utilizing an autoject 2 device to determine overall injection satisfaction.

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 study will consist of a 2 week treatment period with participants injecting their current therapy of Copaxone 20 mg/1.0 mL glatiramer acetate utilizing an autoject 2. All participants will then roll over to the new formulation of 20 mg/0.5 mL glatiramer acetate with an autoject 2 device for a 4 week treatment period. Patient satisfaction will be evaluated using an Experience Questionnaire throughout 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

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
Change From Week 2 to Week 6 in Composite Score of Patient Satisfaction With Injection Experience
Time Frame: Week 2 (prior to first injection with 20 mg/0.5 mL formulation), Week 6 (after 4 weeks of treatment with 20 mg/0.5 mL formulation).
The Satisfaction with Injection Experience questionnaire consists of 5 questions where participants are asked to rate their injection experience over the past 2 weeks on ease of use, bother, acceptability, confidence to inject and satisfaction. The response options range from "strongly disagree" (score = 1) to "strongly agree" (score = 5). The composite score of Satisfaction with Injection Experience is defined as the mean of the five Likert questions. The composite score ranges from 1.0 to 5.0, with a score of 5.0 representing the most satisfaction with injection experience and a score of 1.0 representing the least satisfaction with injection experience.
Week 2 (prior to first injection with 20 mg/0.5 mL formulation), Week 6 (after 4 weeks of treatment with 20 mg/0.5 mL formulation).

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
Patient Injection Experience Preference
Time Frame: Week 4
The Injection Experience Preference Questionnaire utilizes a 5-level preference scale where participants were asked to compare their injection experience during the first 2 weeks (glatiramer acetate 20 mg/1 mL) with the past 2 weeks (glatiramer acetate 20 mg/0.5 mL). Response options were: 1. "strongly prefer first experience (first 2 weeks)"; 2. "somewhat prefer first experience (first 2 weeks)"; 3. "no preference"; 4. "somewhat prefer second experience (past 2 weeks)"; 5. "strongly prefer second experience (past 2 weeks)." Responses 1 and 2 were combined into a single category (prefers first experience) and responses 4 and 5 were combined into a single category (prefers second experience).
