The purpose of this study will be to demonstrate the safety, tolerability, and efficacy of arimoclomol in subjects with SOD1 positive familial Amyotrophic Lateral Sclerosis (ALS). This type of ALS is HEREDITARY (runs in families), and at least one other person in the family must have had ALS. Study hypotheses: Arimoclomol, taken at a dose of 200 mg three times daily will improve survival as defined by time to death, tracheostomy or permanent assisted ventilation. In addition, it will be safe and well tolerated in subjects with SOD1 positive familial ALS. Funding Source - FDA-OOPD
