Official title
Validation of a Laboratory Test Measuring Natalizumab (Tysabri®) Serum Levels in a Multiple Sclerosis Patient Cohort
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Validating a peptide-based laboratory test enabling the measurement of Tysabri® serum levels (pharmacokinetics, PK) in multiple sclerosis patients undergoing therapy. The results of this newly developed test will be compared to Tysabri® serum levels measured in parallel using an independent test. We will also simultaneously measure a pharmacodynamic marker of Tysabri®, receptor saturation levels on blood immune cells, which is thought to correlate with Tysabri® serum levels.
