ERYTECH Pharma (Paris:ERYP) (ADR:EYRYY), a clinical-stage biopharmaceutical company developing innovative therapies by encapsulating therapeutic drug substances inside red blood cells, today provided a business update and reported its financial results for the six-month period ended June 30, 2017.

“The positive results of eryaspase in second-line metastatic pancreatic cancer have been highly significant for ERYTECH,” commented Gil Beyen, ERYTECH’s Chief Executive Officer. “Not only do these results open the door for eryaspase to become a potentially important therapy in the treatment of second-line metastatic pancreatic cancer, an area of high unmet medical need with very limited treatment options, they are also the basis for exploration of additional clinical development opportunities in this disease and in other solid tumors. Our capital raise in April significantly strengthened our balance sheet and enables us to build on these opportunities. The next key steps are meetings with the U.S. FDA, scheduled for October, and the Committee for Medicinal Products for Human Use, or CHMP, to be scheduled later in 2017, to discuss the development path and design of a potential Phase 3 study for eryaspase in pancreatic cancer. Concurrently, our preclinical teams are exploring other possible solid tumor indications in areas of high unmet medical need. In the meantime, we are preparing our MAA resubmission, including the supplementary data requested by the CHMP, for the potential EU approval of eryaspase for the treatment of relapsed or refractory ALL. We believe we have made substantial preclinical program advancements in oncology and metabolic diseases as part of our strategy to further expand our ERYCAPS technology.”
