Trial Outcomes & Findings for Phase 3 Study of Dexpramipexole in ALS (NCT NCT01281189)

NCT ID: NCT01281189

Last Updated: 2021-06-07

Results Overview

The Composite Assessment of Function and Survival (CAFS) is a between-group comparison of a single ranked clinical outcome based on (1) the change from baseline in ALS Functional Rating Scale-Revised (ALSFRS-R) score and (2) time to death. Each subject is ranked according to time-to-death (earlier deaths ranked lower than later deaths). Subjects who survive are ranked more favorably than subjects who died. Among the survivors, subjects are ranked according to change in ALSFRS-R (greater worsening of ALSFRS-R is ranked lower than less worsening or an improvement in ALSFRS-R). The ranked scores range from 001 to 941 (the number of subjects in the Efficacy Population) with larger rank score numbers associated with a better outcome. The ranks were analyzed using an ANCOVA model, which includes treatment as a fixed effect and adjusts for baseline ALSFRS-R score, duration of symptoms, site of onset, and use of riluzole. The least square mean rank score is presented for each treatment group.

Participant Flow

There were 942 participants (468 received placebo and 474 received dexpramipexole) recruited from 81 investigational sites in 11 countries worldwide. One additional participant was randomized in error and was not dosed. This subject was assigned to the placebo arm, but was removed from the intent-to-treat population as a result of the unintentional randomization performed in error by the site.

PRIMARY outcome

Timeframe: 12 months

Population: The efficacy population is defined as subjects who were randomized and received at least 1 dose of study treatment and who either had at least 1 available post-dosing efficacy evaluation (ALSFRS-R) or died during the study period. Subjects were analyzed in the treatment group to which they are randomized.

The Composite Assessment of Function and Survival (CAFS) is a between-group comparison of a single ranked clinical outcome based on (1) the change from baseline in ALS Functional Rating Scale-Revised (ALSFRS-R) score and (2) time to death.

Subjects were analyzed in the treatment group to which they are randomized.

The longest duration of follow-up for this time to the death analysis was 12 months. In the study, subjects were followed for 12-18 months.

Population: The efficacy population is defined as subjects who were randomized and received at least 1 dose of study treatment and who either had at least 1 available post-dosing efficacy evaluation (ALSFRS-R) or died during the study period. Subjects will be analyzed in the treatment group to which they are randomized.

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.

Timeframe: 18 months

Population: The efficacy population is defined as subjects who were randomized and received at least 1 dose of study treatment and who either had at least 1 available post-dosing efficacy evaluation (ALSFRS-R) or died during the study period. Subjects were analyzed in the treatment group to which they are randomized.

Time to Death or Respiratory Insufficiency (DRI) is defined as receipt of a tracheostomy or the use of non-invasive ventilation (NIV) for ≥22 hours per day for at least 10 consecutive days. If NIV is used to meet the criteria for respiratory insufficiency, no measured slow vital capacity (SVC) at any subsequent assessment may be \>50%. Time to DRI is calculated from the date of the first dose to the first date of one of the following events: death, tracheostomy, or the 10th day of consecutive NIV with no measured SVC \>50% at any subsequent assessment.

Population: Subjects who were randomized, received at least 1 dose of study treatment, had at least 1 available post-dosing efficacy evaluation (ALSFRS-R) or died during the study period. Subjects were analyzed in the treatment group to which they are randomized. An attempt was made to collect living status for each subject 18 months after randomization, regardless of the subject's disposition in the study (active or discontinued) or primary reasons for discontinuation.

Estimated time to death up to 18 months. This includes deaths reported greater than 30 days following discontinuation from the study (the time period for reporting all-cause mortality), regardless of subject disposition, up to 18 months from first dose.

SECONDARY outcome

Timeframe: 18 months

Population: The intent-to-treat (ITT) population is defined as subjects who were randomized and received at least 1 dose of study treatment.

The date of reaching ≤50% of predicted upright slow vital capacity (SVC) is defined as the date of the first visit at which a predicted upright SVC is ≤50% and continues to remain ≤50% at the subsequent visit except for the last available observation. The time to reach ≤50% of predicted upright SVC is defined as the duration between the date of reaching ≤50% of predicted upright SVC and the date of the first dose of study medication. If the subject is alive and does not reach ≤50% of predicted upright SVC, the time to reach ≤50% of predicted upright SVC will be censored and equal to the number of days from the first dose of study medication until the visit date when the subject's last available SVC assessment is performed. The earliest time (Reaching ≤50% Predicted Upright SVC or death) is used in analysis.
