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.
설명
Inclusion Criteria:
- Ability to understand the purpose and risks of the study and provide signed and dated informed consent and authorization to use protected health information (PHI) in accordance with national and local subject privacy regulations.
- Aged 18 to 80 years old, inclusive, at the time of informed consent.
- Must be a patient with a relapsing form of Multiple Sclerosis enrolled in the TOUCH Prescribing Program who is not expected to discontinue Tysabri® therapy prior to completion of the requirements of this study.
- Must have participated in IIT I (Foley, IIT 1 001-001-TY) in March, April, or May of 2010.
- Must have a magnetic resonance imaging (MRI) brain scan, performed prior to the initiation of treatment with natalizumab, on file.
- Must weigh between 38 and 180 kg, inclusive.
- Up to 40 patients will be asked to also participate in Part B, the PK/PD subset,
- Approximately fifty patients will be asked to also participate in the sub-study Part C. These patients will have been in the bottom 20th percentile for iATP in Foley IIT 1 001-001-TY.
Exclusion Criteria:
