Other Information:

Purpose: To examine the clinical efficacy and safety of ultra-high dose (50mg, im, twice a week) methylcobalamin in retarding the progression of symptoms in amyotrophic lateral sclerosis (ALS) patients, we enroll ALS patients diagnosed by revised-Awaji-El Escorial criteria within 12 months after the clinical onset. First they are followed for 12 weeks with Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised(ALSFRS-R) scores, and only those who exhibit drops of 1-2 points are allowed to enter into the test period. A total of 128 patients are randomized and the half having placebo. They are blindly evaluated for drops of ALSFRS-R in 16 weeks, as the primary outcome. After this, all subjects receive methylcobalamin.
Eligibility: 20 Years and older, all genders, not accepting healthy volunteers
