European Commission indication extension on 15 October 2026; OPERETTA 2 Phase 3 evidence is separate

EU authorises intravenous Ocrevus for active relapsing MS from age 10

What happened

On 15 October 2026 the European Commission extended the EU indication for intravenous ocrelizumab (Ocrevus) to patients aged 10 and older with active relapsing multiple sclerosis (MS), defined by clinical or imaging features. EMA updated its product information on 16 October. The September CHMP opinion was an earlier step. Phase 3 OPERETTA 2 evidence, its registry status and its posted results are separate from this regulatory event.

What this means for people with MS

The decision adds an EU-authorised option for eligible children under specialist care. It does not establish individual eligibility, superiority, myelin repair, Greek availability or reimbursement. A separate EMA safety communication disseminated on 8 October warns of drug-induced liver injury and recommends liver-function monitoring; the communication says its frequency is unknown. That safety event is not the 15 October decision.

What kind of evidence exists?
EMA EPAR procedure VR/0000309389 and updated product information
How reliable is this source?
European Medicines Agency (EMA) EPAR and product information; EMA is regulator and Roche Registration GmbH is authorisation holder.

Frexalimab: Greece authorises the long-term Phase 3 extension study

Organisation: Sanofi · France

The EU Clinical Trials Information System (CTIS) shows that Greece authorised Sanofi's Phase 3 extension study LTS18002 (2026-525688-41-00) on 2 November 2026. Denmark, Portugal and Poland authorised it on the same day, after Belgium (30 October 2026) and Austria (1 November 2026); all six countries are listed as authorised with recruitment pending. The record plans 17 participants in Greece and lists four Greek hospitals: AHEPA University General Hospital of Thessaloniki, the University General Hospital of Ioannina, the General University Hospital of Larissa and the 401 General Military Hospital of Athens. The study will look at the long-term safety and tolerability of frexalimab, an experimental antibody, in people with multiple sclerosis (MS). It is open only to people who complete earlier frexalimab studies on the study drug, such as the Phase 3 studies FREXALT and FREVIVA. The estimated EU recruitment start is 15 February 2027.

What this means for people with MS

Authorisation means the study may proceed in Greece; it does not mean that it has started at any Greek hospital, that anyone has received treatment in it, or that frexalimab works. No Phase 3 results are available yet. People who are not already in a frexalimab study cannot join this extension, so it is not a way for other people with MS in Greece to receive frexalimab. Frexalimab is not an available treatment in Greece.

Frexalimab: long-term Phase 3 extension study authorised in Belgium and Austria

Organisation: Sanofi · France

The EU Clinical Trials Information System (CTIS) shows that Belgium authorised Sanofi's Phase 3 extension study LTS18002 (2026-525688-41-00) on 30 October 2026 and Austria on 1 November 2026. The study will look at the long-term safety and tolerability of frexalimab, an experimental antibody given into a vein or under the skin, in people with multiple sclerosis (MS). It is open only to people with relapsing MS or non-relapsing secondary progressive MS who complete earlier frexalimab studies on the study drug, including the Phase 3 studies FREXALT and FREVIVA. It plans 1,710 participants in total. Both countries are listed as authorised with recruitment pending; the estimated EU recruitment start is 15 February 2027.

Post hoc analysis of two completed Phase 3 trials in relapsing MS

OPERA trials: post hoc look at disability worsening in Black and Hispanic or Latino participants

Organisation: Keck School of Medicine, University of Southern California, with Genentech and Roche · United States

Researchers led by the University of Southern California, with authors from Genentech, Roche and other US centres, re-analysed the OPERA I and II trials, which compared ocrelizumab with interferon beta-1a for two years in relapsing multiple sclerosis (MS). In the interferon group, non-Hispanic Black and Hispanic or Latino participants had a higher risk of disability worsening confirmed after 24 weeks, measured with a combined (composite) disability measure, than non-Hispanic White participants (hazard ratio 3.0 and 2.3). Non-Hispanic Black and Hispanic or Latino participants also had more CD19-positive B cells at the start. In 1,138 participants who consented to genetic analysis, higher African or Americas genetic ancestry was also linked to higher risk. Ocrelizumab lowered B cells in all groups. Compared with interferon, it lowered the risk of this composite disability worsening in Hispanic or Latino participants (hazard ratio 0.38; 95% confidence interval 0.20–0.72). In the 65 Black participants the estimate also pointed to lower risk (hazard ratio 0.41), but the 95% confidence interval of 0.13–1.29 includes no difference, so the result is not statistically significant.

What this means for people with MS

This is not a new treatment or a new approval: ocrelizumab is already an approved MS treatment. The analysis was done after the trials ended, in small subgroups (only 65 Black participants), using self-reported race and ethnicity; it cannot show why risk differed and does not change treatment guidance. The authors conclude that ocrelizumab reduced risk regardless of race or ethnicity, but for Black participants the study alone does not establish this. It does not establish availability or reimbursement in Greece or support changing an individual treatment without a neurologist.
