Sponsored by Northwestern University · Observational
The primary outcome measure is PIRA (progression independent of relapse activity), based primarily on clinical assessment, dichotomized as present or not.
For Aim 1, the cohort, patient-derived disability status (PDDS) score, and ambulation score (self-reported) will be the primary endpoints of interest.
For Aim 2, the clinical trial, PIRA will be measured pre-GLP-1 start and at study end (week 72). A composite score of disability, similar to the ORATORIO13 trial will be constructed including EDSS score, 25-foot timed walk, 9-hole peg test, and SDMT score.
STUDY PROCEDURES:
Aim 1 will allow fully remote participation, drawing from geographically diverse settings throughout the USA. Participants in Aim 1 do not need to visit the study site in person or be independently mobile but must be continuously available during the study timeframe remotely for PROMS and study surveys and calls.
Participants will be enrolled for an estimated 72 weeks: Measurements will be requested every four weeks (i.e. q28 days) on a specifically designed survey instrument for MS participants. Participants will be asked to report medication dosing, adherence to medicine, tolerability, weight, height, and exercise activities. Self-reported scales will be administered to the participants as well (measuring disability, fatigue, mood, and quality of life).
Participants must be currently on Ocrelizumab (last dose within the past \<6 months) and currently taking a GLP-1 medication.
Participants will be contacted and interviewed via Zoom every 6 months to ensure study procedures are going as planned, verify data reported on medication and MS disease history, and ensure study procedures are operating smoothly. Participants who do not complete the surveys within 7 days of the scheduled timing will be contacted by a study coordinator by phone up to 3 times. Participants will also be asked to report any medication changes, dose changes, or discontinuations if they occur at any point between study visits.
Participants will be enrolled until a total of 40 individual participants are reached. Study procedures for each group are listed in Tables 1 and 2. All scheduled events will be part of the study and not part of routine clinical care.
Allocation and Blinding
All participants will be treated with the two drugs of interest: Ocrelizumab and the GLP-1 agonist. The participants will be blinded to the study outcome of interest, i.e. progression or PIRA. The investigators will not be blinded to the study outcome. The participants will not have access to their prior PDDS scores on file, earlier in the study. The EDSS raters will not have access to the prior EDSS scores on file, earlier in the study. The statisticians will not be blinded to the study outcome.
Criteria for Study Drug Discontinuation in a Single Participant
Reasons for GLP-1 agonist drug discontinuation will be at the discretion of the treating prescriber include: (1) laboratory test abnormalities (e.g. transaminitis) whether related to the drugs or not; (2) intercurrent illness; (3) severe intolerance to the GLP-1 agonist; (4) lack of access to the GLP-1 drug within an affordable range; (5) patient preference; (6) achieved weight target earlier than anticipated; or (7) any other reason as determined by the prescribing physician or study principal investigator.
Criteria for Study Withdrawal of a Participant
Participants who discontinue GLP-1 agonist drugs for any reason, including tolerability, cost, desired weight loss outcome, etc., will continue to be observed until the end of the study period. It is possible that participants will have periods of discontinuation and then resume GLP-1 agonist treatment. The participant will be observed until (a) week 72 visit (i.e. end of study period), (b) participant withdrawal with no consent to continue monitoring, or (c) investigator-decided withdrawal of a participant from the study (e.g. severe medical illness preventing study completion, departure far from study site, etc.).
There is no anticipated drug development or future product anticipated in this study. A study participant will not have any right to compensation or ownership interest related to such development.

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

The cohort will implement patient-reported outcome measures (PROMs) in 60 people with MS already treated with both Ocrelizumab and a GLP-1 agonist to assess progression and ambulation, while recording drug tolerability and potential adverse events, weight loss, disease-based outcomes focused on progression, and MS-focused quality of life.
Drug: GLP-1 · Drug: Ocrelizumab (US)
The cohort will include a single-arm, open-label trial of 40 Ocrelizumab-treated MS patients who are soon starting GLP-1 agonists, monitored prospectively for 2 years to measure MS progression (clinical disability worsening, stability or improvement) every 3 months, including (a) clinical assessments (e.g. EDSS, 25-foot timed walk, SDMT) as used in the ORATORIO trial of Ocrelizumab, (b) PROMs on progression in MS including fatigue, ambulation distance, mood; and (3) simple objective biomarkers of disease (e.g. plasma neurofilament light chain, glial fibrillary acidic protein).
Drug: GLP-1 · Drug: Ocrelizumab (US)
Glucagon-like peptide-1 agonist agent is the study agent of interest. This study will not supply the GLP-1 drug but depends on the patient's clinical prescription of this drug.
Also known as: Glucagon-like peptide-1, GLP-1 Agonist
All participants will be treated with Ocrelizumab for the indication of MS; however, the study will not provide Ocrelizumab as it will be part of the participant's routine clinical care.
Also known as: Ocrevus
This study also gives Semaglutide. No intervention listed here names it: that was found by reading the record.
PIRA
The primary outcome measure is PIRA (progression independent of relapse activity), based primarily on clinical assessment, dichotomized as present or not.
Time frame: From enrollment to the end of study at 72 weeks.
Neurofilament light chain
There will be blood draws in Aim 2's clinical trial population. Aim 1's observational, interactive cohort will have an optional blood draw component. In both cases, the blood tests will involve send out testing for neurofilament light chain and in Aim 2, glial fibrillary acidic protein.
Time frame: From the start of Aim 2 to the end of treatment at 72 weeks.
