Brief Summary:
Evaluate the efficacy of riluzole 50-mg bid defined by comparing the percentage of riluzole-treated subjects who experienced death, permanently assisted ventilation (PAV) or tracheostomy, to a group of recent historical controls for the treatment of amyotrophic lateral sclerosis (ALS).

Condition or disease Intervention/treatment Phase
Amyotrophic Lateral Sclerosis Drug: Riluzole Phase 4

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 414 participants
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Care (Canadian ALS Riluzole Evaluation) Multicentre Phase IV Comparative Study of the Effects of Riluzole 50mg Bid on the Survival of ALS Subjects Compared to Historical Controls
Study Start Date : January 2001
Study Completion Date : December 2004

Primary Outcome Measures :
  1. The primary efficacy endpoint was the time to the occurrence of an ALS-related event (PAV, tracheostomy or ALS-related death)

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Diagnosis of ALS confirmed by the following definition:

    (a)"Probable" or "Definite" Amyotrophic Lateral Sclerosis (ALS) according to the El Escorial criteria(b)"Peripheral" onset form (limb involvement) or a "Bulbar" form of ALS with a duration of five years, based on inquiry for the earliest symptoms of the disease

  • A subject who simultaneously presents with bulbar and peripheral signs at onset of ALS disease should be stratified to the bulbar onset group. The neurologic progression of such subjects matches that of the bulbar onset ALS subjects.
  • Pulmonary Function: forced vital capacity (FVC) must be 3 60% at study entry.
  • Females of childbearing potential must be documented to be using acceptable birth control methods such as an IUD or oral contraceptives.

Exclusion Criteria:

  • Previous treatment with riluzole
  • Tracheostomy, or expected to undergo a tracheostomy within two months after study inclusion
  • Signs of clinical dementia and/or major psychiatric disorders
  • Serious concomitant disease or handicap likely to interfere with the subject's assessments or impact on the subject's survival
  • A multiple conduction block has been shown on nerve conduction studies by electromyogram
