Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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 14 patients with relapsing MS who are initiating treatment with ocrelizumab, and follow them for 30 months.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 again at 6 months, 12 months, and 30 months after first visit.

Participants will receive standard treatment (ocrelizumab) and have standard exams, MRIs, and tests while on the study.

Study participation is about 30 months, which includes about 9 study visits. Some study visits may be up to 5 hours long. 14 people will take part in this study.

Patients with relapsing MS

Patients with relapsing remitting MS who are intending to receive ocrelizumab.

All patients in the study will be treated with ocrelizumab

Intervention Type DRUG

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.

7. Patient does not have any clinically significant medical conditions based on medical history, physical examination, and laboratory screening, as defined by the investigator, which would interfere with the conduct of the study.
8. Patient is willing and able to comply with the protocol assessments and visits, in the opinion of the investigator.
9. For women of childbearing potential: agreement to use an effective birth control method and avoid breastfeeding during the study period, and for those patients who have received ocrelizumab, for at least 6 months after the last dose.

1. Able to understand the purpose and risk of the study and provide written informed consent.
2. Have participated in the core study and continue to receive ocrelizumab.
3. Have not passed week 120±14 days post initial ocrelizumab dose in the core study.
4. Diagnosis of relapsing MS at time of consent.
5. Patient is willing and able to comply with the protocol assessments and visits, in the opinion of the investigator.
