Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
A
Methyl-B12
methylcobalamin
Methylcobalamin (25,000μg/ml), at a dosage of 64.5μg/kg, or saline placebo administered subcutaneously, once every three days for six weeks. At six weeks, subjects cross over to the other treatment given every three days for another six weeks. Post 12 weeks, treatment with open label methylcobalamin will continue once every three days, for six months.
B
Saline placebo
saline placebo
Methylcobalamin (25,000μg/ml), at a dosage of 64.5μg/kg, or saline placebo administered subcutaneously, once every three days for six weeks. At six weeks, subjects cross over to the other treatment given every three days for another six weeks. Post 12 weeks, treatment with open label methylcobalamin will continue once every three days, for six months.
