Hybrigenics total revenues for H1 2012 remained stable at about €2 million. A slight decrease of

5% in revenues from protein interactions services (turnover and grants of €1.40 million vs.

€1.48 million) was compensated by the increase of 25% in turnover from the research collaboration with Servier (€0.375 million vs. €0.3 million).

Hybrigenics' cash position on June 30th, 2012 amounted to €4.2 million compared to

€2.7 million on December 31st, 2011, and €1.9 million on June 30th, 2011. During H1 2012, a total of €3.8 million has been raised: €3.3 million from two consecutive PIPEs in March and €0.5

million earlier in the year from drawings on the equity line agreement with the American fund

Yorkville Global Advisors; €8.2 million are still available on this line.

"The revenues generated by our research and services activities showed a remarkable resistance to the tough economic environment for outsourcing or public funding of basic research," said Remi Delansorne, Hybrigenics' CEO. "Our cash position is at its highest level since the end of 2007, just after the IPO. These funds allow us to finance as planned the clinical trial of inecalcitol in chronic lymphocytic leukemia".

first-line treatment of metastastic castrate-resistant prostate cancer in combination with Taxotere®, which is the current gold-standard chemotherapeutic treatment for this indication.

Hybrigenics has a research collaboration with Servier on deubiquitinating enzymes and their inhibitors in oncology, neurology, psychiatry, rheumatology, ophthalmology, diabetes and cardiovascular diseases.
