A Systems Approach to Understanding Disease Processes in Multiple Sclerosis
Study Details
Study Description
Brief Summary
This pilot study will establish a proof of concept for using a systems biology approach to characterize the dynamics of MS disease processes. The primary objective of the study is to identify multi-omic (genetic, proteomic, biochemical and/or microbial) factors that correlate with clinical and subclinical MS disease activity. Identification of such biomarkers could have an immediate clinical utility in identification of MS patients prone to more aggressive disease earlier in their disease course, thus affording the opportunity to better individualize therapy.
In addition, insights from better understanding of the complex interplay of various systems biology factors should improve our understanding of MS in general. The study will recruit 50 patients with relapsing MS who are initiating treatment with ocrelizumab, and follow them for 15 months, with an optional extension phase up to 24 months, using a suite of clinical, para-clinical and biological assessments. After 75% of the patients have completed 12 months, analysis will be conducted and reported to Roche/Genentech, to determine whether to pursue the extension phase.

Detailed Description
The main purpose of the study is to improve the understanding of MS and to look at the genetic factors that may influence how MS progresses. This will involve collecting blood and stool samples, patient questionnaires, and MS-related assessments.
About 67 mL (13 tsp) of blood will be collected at the first visit, and then again 1 year later. An additional 13 mL (2.5 tsp) sample is collected at Visit 3 and Visit 5.
Participants will receive standard treatment (ocrelizumab) and have standard exams, MRIs, and tests while on the study.
Study participation is about 15 months, which includes about 9 study visits. Some study visits may be up to 5 hours long. There may be an optional 'extension phase' of the trial to 18-24 months.
50 people will take part in this study.

300 mg of OCR IV infusion will be given on Day 0 followed by a second dose of 300 mg OCR 14 days later ± 2 days, and then 600 mg of OCR as a single infusion will be given every 24 weeks thereafter per standard medical care.
