NEOVACS STRENGTHENS NORTH AMERICAN PRESENCE WITH FORMATION OF U.S. SUBSIDIARY

Paris, March 23, 2015 – NEOVACS (Alternext Paris : ALNEV, FR0004032746), a leader in active immunotherapies for the treatment of autoimmune diseases, is proud to announce the establishment of its wholly-owned U.S. subsidiary, Neovacs, Inc. Neovacs, Inc. is headquartered in Boston and has been incorporated in Delaware. The creation of this U.S. subsidiary marks an important strategic step for Neovacs, as the Company extends its clinical initiatives for lead product candidate, IFNα-Kinoid, beyond the EU to the U.S. market. The establishment of this subsidiary follows the formation of a U.S. Scientific Advisory Board in October 2013.

Arlene Morris, Director of Neovacs and CEO of Syndax Pharmaceuticals, has been named Chairman of Neovacs, Inc. Miguel Sieler, current CEO of Neovacs will also hold the position of CEO of the subsidiary.

"We are thrilled to expand our U.S. operations through the formation of Neovacs, Inc., and believe that the subsidiary will be instrumental to our ongoing clinical and regulatory efforts in support of IFNα-Kinoid in systemic lupus erythematosus ("lupus") and dermatomyositis. The United States has the world's highest lupus prevalence, totaling over 1.5 million reported cases¹ , and the unsatisfactory treatment options create a substantive opportunity for Neovacs as we continue to advance IFNα-Kinoid for this indication. Based on our analysis of IFNα-Kinoid to date, we believe the compound has significant potential in the treatment of lupus, and look forward to the ongoing development of the product as we work to bring potential relief to this large patient population," commented Miguel Sieler, CEO of Neovacs.

Neovacs plans to launch a phase IIa clinical trial of IFNα-Kinoid in this indication in early 2016. The Company is also planning to launch further U.S. trials of IFNα-Kinoid in dermatomyositis, an orphan skin and muscular disease, in the short-to-mid term.

The role of Neovacs, Inc. will be to raise the profile of Neovacs with the medical and financial communities in the U.S.. Neovacs, Inc. will work directly with the U.S. Food and Drug Administration as the Company prepares to initiate its planned lupus and dermatomyositis trials, including securing all regulatory approvals and potential orphan drug status for IFNα-Kinoid in dermatomyositis. Additionally,
