Hybrigenics Reports Increased Revenue From Its Proteomics Services For The First 6 Months Of 2010

Paris, 03 August 2010 – Hybrigenics (ALHYG), a bio-pharmaceutical company listed on Alternext (NYSE-Euronext) in Paris, with a focus on research and development of new cancer treatments and specialized in protein interactions, today announces its revenue and cash position for the first half of 2010.

EUR (thousands) H1 2010 H1 2009 Change % Hybrigenics Services SAS Revenue 1,710 1,645 +4.0% Other Revenues (incl. Pharma) 370 795 -53.5% Hybrigenics SA total revenue 2,080 2,440 -14.8% Net cash position 2,995 1,770 +69.2%

The first half-year revenue from Hybrigenics Services SAS has increased by 4 percent to EUR 1.71 million. Due to the slowdown of the pharma research activities for Servier, which peaked in value in the first half of 2009, Hybrigenics’ other revenue has decreased from EUR 0.8 million in H1 2009 to EUR 0.37 million in H1 2010. Hybrigenics’ pharma research is now totally focussed on its own drug discovery program to generate proprietary results. As a consequence, Hybrigenics SA total revenue has decreased by 15 percent to EUR 2.08 million.

The Hybrigenics Services SAS subsidiary has recently been established to integrate all Yeast Two-Hybrid (Y2H) and related activities in one dedicated entity. Its mission is to serve this highly specialized segment of the fee-for-service proteomics market in an optimal way, and thereby boost future revenues.

Hybrigenics’ net cash position on 30 June 2010 amounted to EUR 3 million as compared to EUR 3.6 million on 31 December 2009. During H1 2010 a total of EUR 0.75 million has been drawn from the equity line agreement with the American fund Yorkville Global Advisors; EUR 4.17 million are still available on this line.

“During this first half of 2010, a major milestone in the development program of inecalcitol has been reached with the determination of the maximal tolerated dose of 4 milligram per day in hormone-refractory prostate cancer patients. The current clinical Phase IIa study will now be completed in the next few months,” said Remi Delansorne, Hybrigenics SA’s CEO. “The intellectual property protecting inecalcitol has been reinforced and prolonged by two patent applications. We also received a positive official scientific advice from the European Medicines Agency earlier this year. All these important achievements were obtained with minimal cash expenditure,” added Remi Delansorne.
