The Committee for Medicinal Products for Human Use gave a positive opinion on the drug, sarilumab (Kevzara), citing its ability to reduce the signs and symptoms of RA.
Sarilumab, the active substance of Kevzara, a treatment for adult patients with moderate to severe RA, works by blocking a protein called IL-6, which is associated with inflammation.
The panel’s opinion will now be reviewed by the EMA.
In October, U.S. regulators declined to approve sarilumab because of manufacturing deficiencies at a Sanofi plant in France.
Regeneron said in February that it was planning to resubmit a marketing application to the U.S. Food and Drug Administration for sarilumab.
The drug has already been approved by Canadian health regulators to treat RA.
More than 23 million people worldwide suffer from RA. Current treatments include the widely used methotrexate, as well as non-steroidal anti-inflammatory drugs.
Other IL-6 inhibitors for RA include Roche Holding AG’s approved Actemra and Johnson & Johnson’s experimental sirukumab.
Last Friday, the FDA declined to approve a new RA drug, baricitinib, made by Eli Lilly and Co and partner Incyte Corp.
