Regulatory News:

ERYTECH Pharma (Paris:ERYP) (ADR:EYRYY), the French biopharmaceutical company that develops innovative ‘tumor starvation’ treatments for acute leukemia and other oncology indications with unmet medical needs, reports cash balance and revenues for the third quarter of 2015.

ERYTECH ended the third quarter of 2015 with a total net cash position, including short term treasury investments, of € 28.2 million, compared to total net cash position of € 31.0 million at the end of the second quarter of 2015. The total net use of cash amounted to € 2.8 million for the third quarter of 2015, compared to € 3.4 million in the second quarter of 2015.

These results are in line with the expectations and strategy of the company for 2015, which remains focused on the clinical development of its innovative treatments for acute leukemia and other oncology indications in Europe and in the United States.

ERYTECH has five ongoing clinical programs for its lead product candidate, ERY-ASP, which is known under the trade name GRASPA® in Europe and Israel. The company has reported positive results from its completed Phase 2/3 pivotal clinical trial in Europe of GRASPA® in children and adults with relapsed or refractory acute lymphoblastic leukemia (ALL) based on which it submitted a Marketing Authorization Application dossier to the European Medicines Agency in September of this year, and currently expects that it could receive European marketing approval by the end of 2016. The four other trials are: a Phase 2b clinical trial in Europe in patients with acute myeloid leukemia (AML), a Phase 2 clinical trial in France in patients with pancreatic cancer, an Expanded Access Program in France to provide GRASPA to ALL patients and a Phase 1 clinical trial of ERY-ASP in the United States in adults with newly diagnosed ALL.

About ERYTECH and ERY-ASP (GRASPA®): www.erytech.com

Founded in Lyon, France in 2004, ERYTECH is a clinical-stage biopharmaceutical company developing innovative therapies for rare forms of cancer and orphan diseases. Leveraging its proprietary ERYCAPS platform, which uses a novel technology to encapsulate therapeutic drug substances inside red blood cells, ERYTECH has developed a pipeline of product candidates targeting markets with high unmet medical needs. ERYTECH’s initial focus is on the treatment of blood cancers, including acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML), by depriving tumors of nutrients necessary for their survival. ERYTECH has recently announced positive efficacy and safety results from its completed Phase 2/3 pivotal clinical trial in Europe with its lead product candidate, ERY-ASP, also known under the trade name GRASPA®, in children and adults with relapsed or refractory ALL. ERYTECH also has an ongoing Phase 1 clinical trial of ERY-ASP in the United States in adults with newly diagnosed ALL, and a Phase 2 clinical trial in Europe evaluating GRASPA as a first-line therapy for the treatment of elderly patients with AML, each in combination with chemotherapy.

ERY-ASP consists of an enzyme, L-asparaginase, encapsulated inside donor-derived red blood cells. L-asparaginase depletes asparagine, a naturally occurring amino acid essential for the survival and proliferation of cancer cells, from circulating blood plasma.

Every year over 50,000 patients in Europe and the United States are diagnosed with ALL or AML. For about 80% of these patients, mainly adults and relapsing patients, current forms of L-asparaginase cannot be used due to their toxicity or as a result of allergic reactions. ERYTECH believes that the safety and efficacy profile of ERY-ASP/GRASPA®, as observed in its Phase 2/3 pivotal clinical trial, offers an attractive alternative option for the treatment of leukemia patients.

ERYTECH believes that ERY-ASP has the potential as a treatment approach in solid tumors and is conducting a Phase 2 clinical trial in Europe in patients with metastatic pancreatic cancer. In addition to its current product candidates that focus on using encapsulated enzymes to induce tumor starvation, ERYTECH is exploring the use of its platform for developing cancer vaccines and enzyme replacement therapies.

The EMA and the U.S. Food and Drug Administration (FDA) have granted orphan drug designations for ERY-ASP/GRASPA for the treatment of ALL, AML and pancreatic cancer. ERYTECH produces ERY-ASP at its own GMP-approved and operational manufacturing site in Lyon (France), and at a site for clinical production in Philadelphia (USA). ERYTECH has entered into licensing and distribution partnership agreements for ERY-ASP for ALL and AML in Europe with Orphan Europe (Recordati Group), and for ALL in Israel with TEVA, which will market the product under the GRASPA® brand name.

ERYTECH is listed on Euronext regulated market in Paris (ISIN code: FR0011471135, ticker: ERYP) and is part of the CAC Healthcare, CAC Pharma & Bio, CAC Mid & Small, CAC All Tradable, EnterNext PEA-PME 150 and Next Biotech indexes. ERYTECH is also listed in the U.S. under an ADR level 1 program (OTC, ticker EYRYY).
