Studienpopulation
Patients with relapsing forms of MS. Conducted at one site in the US. Subjects currently enrolled in TOUCH Prescribing Program, and participated in Foley 001-001-TY eligible.
Subset of approx. 40 patients to participate in Part B. 11 high risk bivalent patients 11 low risk monovalent patients 9 patients who participated in 2009 PK/PD study (Biogen Idec, 101MS406) 9 patients with infusion cycle of 38 days plus or minus 2 days
Part C "Intracellular energetic in Tysabri therapy":
Patients whose iATP fell into the bottom 20th percentile will be asked to participate in a sub-study that includes Part A with the addition of collecting iATP. This number is approximately 50 participants.
Part D patients from 001-001-TY with low or normal IgG4 levels will be asked to participate in sub-study for an additional IgG4 assay collected at 3-5 days post-infusion. This number is approximately 30 participants.
