A phase 3 clinical trial found ultra-high dose methylcobalamin slowed functional decline in patients with early-stage amyotrophic lateral sclerosis. ja.ma/3L1hd6C
Question
Does twice-weekly intramuscular injection of 50-mg ultrahigh-dose methylcobalamin slow clinical progression in early-stage amyotrophic lateral sclerosis?
Findings
In this randomized phase 3 clinical trial that included 130 participants who were enrolled within 1 year from symptom onset and presented with a 1- or 2-point decrease on the Revised Amyotrophic Lateral Sclerosis Functional Rating Scale total score during 12 weeks of observation, the changes in the score were −2.66 with methylcobalamin vs −4.63 with placebo during the 16-week treatment, which significantly differed.
Meaning
Ultrahigh-dose methylcobalamin may slow functional decline in early-stage amyotrophic lateral sclerosis with moderate progression rate.
