Brief Summary:
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.

Primary Outcome Measures :
  1. ALSFRS-R [ Time Frame: during 16 weks of test period ]
    Drop of Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (maximum or normal 48 and minimum 0; higher values represent better condition)


Secondary Outcome Measures :

    time period from drug assignment to death or becoming bound to respirator

  2. %Functional Vital Capacity (FVC) [ Time Frame: during 16 weeks of test period ]
    changes of per cent Functional Vital Capacity

  3. homocystein [ Time Frame: during 16 weeks of test period ]
    changes of serum levels of homocystein

  4. Manual Muscle Testing (MMT) [ Time Frame: during 16 weeks of test period ]
    changes of sum of Medical Research Council scales of manual muscle testing, ranging 5 (normal), 4, 4+, 3, 2, 1, 0 (minimal) ( for analysis each is converted to 6, 5, 4, 3, 2, 1, 0) of the 11 muscles in the limbs (5x2) and neck(1)

  5. Norris scale [ Time Frame: during 16 weeks of test period ]
    changes of Norris scale (39 normal - 0 worst)

  6. Grip Power [ Time Frame: during 16 weeks of test period ]
    changes of sum of grip power in kilograms on both sides

  7. 40-item Amyotrophic Lateral Sclerosis Assessment Questionnaire (ALSAQ-40) [ Time Frame: during 16 weks of test period ]
    changes of sum of ALSAQ-40 (40-item Amyotrophic Lateral Sclerosis Assessment Questionnaire) score (40 normal - 200 worst)


Other Outcome Measures:
  1. safety [ Time Frame: during 16 weks of test period ]
    any adverse events during the study period
