Paris, March 12, 2014 – NEOVACS (Alternext Paris : ALNEV), a leader in active immunotherapies for the treatment of autoimmune diseases, announces that an independent Data and Safety Monitoring Board (iDSMB) reviewing the safety data of the phase IIb clinical trial of TNF-Kinoid in Rheumatoid Arthritis (RA) issued a positive assessement of the study.

The iDSMB is an independent committee of 4 international auto-immune disease experts. Following its evaluation of the safety data on nearly half of the patients forseen in the study, the committee issued a final report on March 11, 2014 with unrestricted approval based on :

• the good safety profile of the Kinoid at the actual stage of the study,

"There are two positive impacts about this recommendation by the iDSMB" comments Miguel Sieler, CEO of Neovacs. "It confirms the excellent safety profile of TNF-Kinoid, as shown in previous studies of the product accross indications. It also sends a positive signal regarding our ongoing clinical trial in RA" .

All study centers (about 40) are operational. Recruitment is on track with study results expected Q4 2014.
