MS Trial Alert: Investigators Recruiting for Trial Comparing Ocrevus® to Placebo for Slowing the Progression of Upper Limb Disability in People with Primary Progressive MS

August 16, 2021

SUMMARY: Investigators in the U.S. and abroad are recruiting 1000 people with primary progressive MS for a study comparing ocrelizumab (Ocrevus®) to placebo for slowing the progression of upper limb disability. The study – also called O’HAND – is sponsored by F. Hoffmann-La Roche.
Rationale: Ocrevus is approved for the treatment of primary progressive MS or relapsing MS, based on clinical trials showing significant benefits against MS relapses and progression. This study is specifically testing whether ocrelizumab can help to preserve arm and hand function. Having the use of the upper limbs can make the difference between remaining independent and requiring substantial daily help from others. Ocrelizumab is an investigational product for purposes of this research.
Eligibility and Details: Participants should be 18 to 65 years old, and diagnosed with primary progressive MS.
Participants will be randomly assigned to receive either ocrelizumab or an inactive placebo via intravenous (into the vein) infusion for 120 weeks. The first two doses are given 14 days apart, and then infusions are given every 24 weeks.
The primary outcome of the study will compare whether ocrelizumab may slow the progression of upper limb disability using a test of arm and hand function called the 9-hole peg test. Secondary outcomes include measures of disability progression using the EDSS scale, changes in MRI-detected brain tissue volume, and safety. The study involves visits to the study site every three months, and will involve MRI scans, blood draws, clinical exams, and questionnaires.
Please note: This study requires in-person visits to the study site. Precautions are being taken to reduce the on-site risks of exposure to COVID-19.

About Multiple Sclerosis

Multiple sclerosis is an unpredictable disease of the central nervous system. Currently there is no cure. Symptoms vary from person to person and may include disabling fatigue, mobility challenges, cognitive changes, and vision issues. An estimated 1 million people live with MS in the United States. Early diagnosis and treatment are critical to minimize disability. Significant progress is being made to achieve a world free of MS.
