Summary description of the study

This extension study includes participants with relapsing Multiple Sclerosis and primary progressive Multiple Sclerosis from the main studies WA21092 (OPERA I), WA21093 (OPERA II), and WA25046 (ORATORIO) to ensure continuity of Ocrelizumab treatment or safety monitoring without interruption and to continue the collection of valuable long-term data on the safety and efficacy of treatment with Ocrelizumab. The investigational product Ocrelizumab is approved in Switzerland. Approximately 1300 study participants from the main studies will participate in this study. In Switzerland, about 7 patients will participate.

Intervention under investigation

This study consists of three parts:

1. Screening (to see if participants are eligible for the study). This can occur at a scheduled visit as part of the main study, but in some cases, a separate visit may take place.

2. Treatment (not applicable if participants are already in the safety monitoring phase of the main study)

3. Safety monitoring (for further observation of participants after treatment completion)

 

Participants will continue to receive Ocrelizumab at the same dose and frequency as during their participation in the main studies, i.e., an intravenous infusion of 600 mg every 24 weeks. This also aligns with the current instructions on the Ocrelizumab label and thus represents the current standard of care.

 

During this study, participants will have a total of about 6-8 visits. After screening, visits will occur every 24 weeks and may last approximately between 4.5 and 7 hours, depending on the duration of the Ocrelizumab infusion.

 

The study duration from screening to the end of safety monitoring is approximately 3.5 years.

 

When participants are enrolled in this study to complete the 48-week safety monitoring phase of the main study, they will have 1-3 visits, depending on how many safety monitoring visits they have already completed in the main study. A total of 48 weeks of safety monitoring is required.
