Safety and Tolerability of Glatiramer Acetate

Injection-related (IR) adverse events refers to all local injection site reactions and/or symptoms or events related to immediate post injection reaction (flushing, chest pain, palpitations, anxiety, dyspnea, throat constriction, and/or urticaria). Rate was calculated as # IR events/the total exposure to study drug in years.

For cases in which more than 1 IR adverse event started on the same date for the same patient, these were counted as 1 IR adverse event for that patient.

Parameter statistics were generated from a Poisson regression model with natural log of treatment duration (years) as an offset variable, and adjusted for baseline EDSS score, treatment group, age, sex, number of relapses in the 2 years prior to screening, in which a contrast comparing treatment groups were constructed. Adjusted mean estimates were adjusted estimates of event rates within treatment group.

This outcome includes injection-related adverse events referring to all local injection site reactions (ISR). Rate was calculated as # ISR events/the total exposure to study drug in years.

For cases in which more than 1 ISR adverse event started on the same date for the same patient, these were counted as 1 ISR adverse event for that patient.

The physical wellbeing assessment portion of the MSIS-29 is comprised of 20 questions in which participants rate the impact of MS on their day-to-day life during the past two weeks from 1=no impact to 5=extreme impact for a total score of 20-100. Negative change from baseline scores indicate improvement in physical wellbeing over time.

The estimated change from baseline to month 4 adjusted for months 1 and 2 was generated using a mixed model repeated measures analysis adjusted for baseline MSIS-29 physical score, treatment group, month, treatment by month interaction.

The psychological wellbeing assessment portion of the MSIS-29 is comprised of 9 questions in which participants rate the impact of MS on their day-to-day life during the past two weeks from 1=no impact to 5=extreme impact for a total score of 9-45. Negative change from baseline scores indicate improvement in psychological wellbeing over time.

The estimated change from baseline to month 4 adjusted for months 1 and 2 was generated using a mixed model repeated measures analysis adjusted for baseline MSIS-29 psychological score, treatment group, month, treatment by month interaction.

The Treatment Satisfaction Questionnaire for Medication (TSQM-9) is a psychometric measure of a patient's satisfaction with medication. It consists of 3 subscales: effectiveness, convenience and global satisfaction. The scores were computed by adding items for each domain, i.e. 1 to 3 for effectiveness, 4 - 6 for convenience and 7 to 9 for global satisfaction. This outcome focuses on convenience items 4-6, with each question graded on a scale of 1 (extreme dissatisfaction) to 7 (extreme satisfaction). TSQM-9 participant perception of convenience score was calculated as: ([sum (Item 4 to Item 6) - 3] divided by 18) * 100. The full range was -100 to 100, with positive change from baseline indicating improvement.

The estimated change from baseline to month 4 adjusted for months 1 and 2 was generated using a mixed model repeated measures analysis adjusted for baseline TSQM convenience score, treatment group, month, treatment by month interaction.

The scores were computed by adding items for each domain, i.e. 1 to 3 for effectiveness, 4 - 6 for convenience and 7 to 9 for global satisfaction. This outcome focuses on global satisfaction, items 7-9. TSQM-9 participant perception of satisfaction score was calculated as: ([sum(Item 7 to Item 9) - 3] divided by 14) * 100. The full range was -100 to 100, with positive change from baseline indicating improvement satisfaction with medication.

The estimated change from baseline to month 4 adjusted for months 1 and 2 was generated using a mixed model repeated measures analysis adjusted for baseline TSQM convenience score, treatment group, month, treatment by month interaction.

An adverse event was defined in the protocol as any untoward medical occurrence in a patient that developed or worsened in severity during the conduct of the clinical study of a pharmaceutical product and did not necessarily have a causal relationship to the study drug. This outcome summarizes the % of participants who had AEs other than injection related reactions. Injection-related (IR) adverse events referring to all local injection site reactions and/or symptoms or events related to immediate post injection reaction (flushing, chest pain, palpitations, anxiety, dyspnea, throat constriction, and/or urticaria).
