|Actual Primary Completion Date :||November 2010|
|Actual Study Completion Date :||December 2010|
Active Comparator: 20 mg/0.5 mL Glatiramer Acetate
Participants received once daily subcutaneous administration of 20 mg glatiramer acetate as 20 mg/1.0 mL utilizing autoject 2 for glass syringe for two weeks (Period 1), followed by 20 mg/0.5 mL utilizing the autoject 2 device for four weeks (Period 2).
Drug: Glatiramer Acetate 20 mg/0.5 mL
20 mg/1.0 mL formulation of glatiramer acetate utilizing the autoject 2 for glass syringe.
Other Name: Copaxone®
Drug: Glatiramer acetate 20 mg/0.5 mL
20 mg/0.5 mL formulation of glatiramer acetate utilizing the autoject 2 20 mg/0.5 mL device.
- 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.
- 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).
