The investigators are measuring the effectiveness of Ocrevus™ in helping patients with hand or arm weakness, especially if posed by a more advanced MS patient than those included in the clinical trials.
Ocrevus™ is the first FDA approved disease-modifying treatment for primary progressive multiple sclerosis (PPMS) as well as relapsing MS. In the clinical trials considered by the FDA (OPERA I/II, ORATORIO), the highest Expanded Disability Status Scale (EDSS) included in the participants was 5.5 (OPERA I/II) and 6.5 (ORATORIO). The EDSS score is heavily weighted on walking ability and is not a useful measurement for UE function. The primary endpoint in the primary progressive MS trial with Ocrevus™ was EDSS and in the relapsing MS studies, EDSS was used as a secondary endpoint. The Multiple Sclerosis Functional Composite (MSFC) score (Z score), a composite of quantitative measure of walking speed, upper limb coordinated movement (9 Hole Peg Test/9HPT) and cognitive function, was obtained as a secondary clinical measure with scores being favorably higher in patients treated with Ocrevus™ (OPERA I/II).The z score, however, is not very useful in delineating which of the three clinical functions was maintained or showed less progression given that three domains are included in the score. Data presented recently from the Oratorio trial analyzed the intention to treat population of PPMS patients and the subgroups of patients with upper extremity functional impairment using the 9HPT; results demonstrated reduction in risk of clinical progression in upper extremity disability in patients treated with Ocrevus compared to placebo. There was improvement in the change from baseline to week 120 in 9HPT time in treated patients. Abnormal baseline 9HPT was defined as \>25 seconds and upper extremities were defined as "better hand" and "worse hand", each individually tested, with clinical progression determined at 12 and 24 weeks in 3 sub-categories of progression: lengthened time of 9HPT \>15%, \>20% and 25%. In this study, investigators aim to not only replicate the results in the Oratorio trial with upper extremity dysfunction, but also widen the spectrum of patients that may benefit (given an expanded MS population of patients, not exclusive to PPMS and widen the It is anticipated that by using a test that better emulates activities of daily life performed with the upper extremity, such as the TEMPA (Test d'Evaluation de la performance des membres Superieurs e Personnes Agees ) more real life application of the benefits of receiving treatment with Ocrevus will be obtained, and it is anticipated that patients can maintain the function they have or potentially improve function.

Ocrelizumab is a humanized anti-CD20 monoclonal antibody. It targets CD20 marker on B lymphocytes and hence is an immunosuppressive drug candidate. Ocrelizumab binds to an epitope that overlaps with the epitope to which rituximab binds

Stabilization of Scores Using the Test d'Evaluation de la Performance Des Membres Supérieurs Des Personnes Agées (TEMPA) -Translasted in English to Mean "Performance Evaluation Test for the Elderly"
The TEMPA is designed to assess the capabilities and limitations of upper limb function and consists of 9 tasks that mimic tasks of daily living that include picking up a jar, taking a spoonful of coffee from a jar, pouring water from a pitcher, handling coins, writing on an envelope and opening a pill container, tying a scarf around one's neck, shuffle and deal playing cards, and picking up and moving small objects. Each task is assessed by a rater by measuring speed of execution (seconds) and by functional rating of the subject's independence in performing them using an ordinal scale of 0 (completed without difficulty) to -3 (could not complete the task).
Time frame: 24 months
Stabilization of the Upper Extremity Functional Index (UEFI)
The Upper Extremity Functional Index (UEFI) is a self-administered questionnaire which measures disability in patients with upper extremity conditions on a 5-point Likert scale. Scores range from 0 to 60 with lower scores indicating more functional difficulty in performing activities of daily living using the upper extremities including household and work activities, hobbies, lifting a bag of groceries, washing their scalp, pushing up on their hands, driving etc.
Time frame: 24 months
Stabilization of 9-Hole Peg Test Scores
The 9HPT is an objective measure of finger dexterity and upper extremity function, which is a widely used measure across most clinical trials in multiple sclerosis populations. The test involves the participant picking up and placing pegs one at time in the 9 holes and removing the pegs from their respective holes as quickly as possible. The participant completes the tasks twice on using their dominant hand, then twice on their non-dominant hand. Higher scores indicate a worse outcome.
