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.
Relapses were monitored throughout the study. During the PC Period, two neurologists/physicians assessed subjects' general medical and neurological evaluations separately. A relapse was defined as the appearance of 1+ new neurological abnormalities or the reappearance of 1+ previously observed neurological abnormalities lasting \>= 48 hours and immediately preceded by an improving neurological state of at \>=30 days from onset of previous relapse. An event was counted as a relapse only when the subject's symptoms were accompanied by observed objective neurological changes, consistent with \>= one of the following: - An increase of \>= 0.5 in the Expanded Disability Status Scale (EDSS) score as compared to previous evaluation. - An increase of one grade in the actual score of \>=2 of the 7 functional systems (FS), as compared to previous evaluation. - An increase of 2 grades in the actual score of one FS as compared to the previous evaluation. Adjusted mean values are displayed.
The annualized relapse rate (ARR) was calculated for the study by dividing the cumulative number of confirmed relapses by the number of person-years of exposure to treatment. The analysis of the annualized relapse rate is based on estimating a contrast (early start vs delayed start) derived from a baseline-adjusted, Negative Binomial Regression model to the number of confirmed relapses observed during study (post randomization) with an "offset" based on the log of exposure to treatment.
A visual analog scale (VAS) was used for subjective characteristics that cannot be directly measured. Respondents specified their level of agreement to a statement by indicating a position along a continuous line between two end-points. The VAS scale used 0 mm to represent "no pain" and up to 100 mm to represent "worst possible pain;" subjects drew a continuous line to represent their level of pain.
Axonal loss in the optic nerve (due to optic neuritis) was assessed by measuring retinal nerve fiber thickness of the affected eye using optical coherence tomography (OCT) at Baseline and Month 6.
A confirmed relapse is defined as the appearance of one or more new neurological abnormalities or the reappearance of one or more previously observed neurological abnormalities. This change in clinical state must last at least 48 hours and be immediately preceded by an improving neurological state of at least thirty (30) days from onset of previous relapse.
Data from interim analysis with database lock on October 14, 2007. The time from randomization to conversion to CDMS as determined by the occurrence of a second clinical attack during the double-blind period. Poser criteria are: Two relapses and clinical evidence of two separate lesions; clinical evidence of one lesion and paraclinical evidence of another separate lesion. The two relapses must involve different parts of Central Nervous System and must be separated by a period of at least one month. Lesions are determined by Magnetic Resonance Imaging (MRI).
Data from interim analysis with database lock on October 14, 2007. Due to the number of participants in the glatiramer acetate group that converted to CDMS (see outcome #6), the 25th percentile was considered when running the Kaplan-Meier estimate for time to conversion to CDMS. Conversion to CDMS is determined by the occurrence of the second clinical attack.
The ALSFRS-R is a questionnaire-based scale for monitoring the progression of disability in patients with ALS. It is composed of 12 items, each scored between 0 and 4.The total score, calculated as the sum of these 12 items, ranges from 0 to 48. The higher the score, the less disabled the participant. Timepoints after baseline were included in calculation of slope of change in ALSFRS-R. Slope is derived from the time by treatment interaction term from the Repeated Measures Analysis of Covariance model. Descriptive statistics of the slope are reported.
