    Frequently Asked Questions

    This section is not a comprehensive source of safety information on ocrelizumab. Due to the nature of post-marketing adverse event reports, information may be duplicated and/or incomplete. Some investigations remain ongoing, and therefore, information is subject to change. Additionally, the existence of an adverse event report does not establish causation. We evaluate these reports through our drug safety department, and attempt to verify the information to the extent possible. The Prescribing Information remains the primary source of information on the known and potential risks of ocrelizumab for RMS and PPMS.

    An adverse event is an untoward medical occurrence in a patient or participant in a clinical investigation, but does not necessarily have a causal relationship with an administered treatment. A post-marketing adverse event report is a report received by Genentech regarding an adverse event in a patient taking one of our marketed products.

    Robust global systems are in place to continuously monitor the safety of a drug, from the time it is first evaluated in clinical studies through commercialization. All adverse event reports are received by Genentech/Roche and due diligence is performed. The reports are then submitted to the FDA as per regulatory requirements.

    Yes; this website includes post-marketing adverse event reports received by Genentech/Roche. As part of our robust global pharmacovigilance process, these adverse event reports are reviewed, assessed, and due diligence is performed.

    The FAERS database generally includes post-marketing cases reported by the Market Authorization Holder. However, FAERS may also include reports from clinical trials based on the specific requirements set in FDA regulations along with reports that are submitted voluntarily to the FDA by other resources. As the FDA acknowledges, unverified information, as well as incomplete or duplicate cases, can be reported in the FAERS dashboard.
