Participant Flow

Subjects were recruited for the study across 20 recruiting centers US between 09 April 2008 and 26 January 2009 in medical centers located the USA.

Study conducted in 2 parts: When the first 12 weeks (Part 1) was completed, eligible continuing subjects entered a 4 week placebo washout before being re-randomized to receive either 50 mg/day dexpramipexole or 300 mg/day dexpramipexole for up to 72 additional weeks.

SECONDARY outcome

Timeframe: 12 weeks

Population: Randomized subjects who had at least 1 post-baseline clinical status evaluation within 7 days of discontinuing study drug

The ALSFRS-R (ALS functional rating scale with respiratory component) is a validated scale which measures 4 functional domains, comprising respiratory function, bulbar function, gross motor skills, and fine motor skills. There are a total of 12 questions, each scored from 0 to 4 for a total possible score of 48, with higher scores representing better function. Slope is calculated using a linear mixed effects model with x-axis time in months and y-axis ALSFRS-R score. Units for slope are change per month in units on the ALSFRS-R scale.

Slope of change in Upright Vital Capacity (percent predicted upright vital capacity) from Baseline to Week 12. A negative change/slope indicates clinical worsening. Slope is calculated using a linear mixed effects model with x-axis time in months and y-axis as percent predicted upright vital capacity. Units for slope are change per month in percent predicted upright vital capacity.
