"The development of DAVANAT^® for approval in the U.S. for metastatic colorectal cancer adds to our overall approach to commercialization of DAVANAT^® which includes expected approval in Colombia, South America in 2011, and the expanded application of DAVANAT^® in administration with cancer vaccines, being developed in collaboration with the Ludwig Institute in Brussels. In addition, we will advance our program using Galectin blockers to treat liver fibrosis which is currently in the pre-clinical phase.”

About DAVANAT^®

DAVANAT^®, the Company's lead product candidate, is a polysaccharide polymer that targets Galectin receptors on cancer cells and interferes with their activity. Peer-reviewed studies have demonstrated that Galectins affect cell development and play important roles in cancer, including tumor cell survival, angiogenesis, tumor metastasis and give the tumor the ability to evade the immune system. To date, DAVANAT^® has been administered to approximately 100 cancer patients. Data from a Phase II trial for end-stage colorectal cancer patients showed that DAVANAT^® in combination with 5-FU extended median survival by 46% compared with the best standard of care as determined by the patients’ physicians. Clinical trial results also showed that patients experienced fewer serious adverse side effects of the chemotherapy.

About GM and GR Series of Anti-Fibrosis Compounds

The GM and GR series of compounds are first-in-class, novel carbohydrate compounds that significantly reduced collagen expression and reversed fibrosis in animal models. Uncontrolled collagen expression is a pathological process that occurs during the fibrotic process, affecting various organs leading to scar tissue. Chemical toxicity, microbial infection or physical injury cause hepatic, renal and other types of fibrosis. Carbohydrate polymers were created and screened to inhibit collagen production in in-vivo and in-vitro fibrosis models.
