ERYTECH Announces Withdrawal of Its European Marketing Authorization Application for GRASPA for Acute Lymphoblastic Leukemia and Prepares for Resubmission

Regulatory News:

ERYTECH Pharma (Paris:ERYP) (ADR:EYRYY) (Euronext Paris: ERYP), the French biopharmaceutical company developing ‘tumor starvation’ treatments for acute leukemia and other oncology indications with unmet medical needs, today announced its decision to withdraw the current MAA for GRASPA for the treatment of acute lymphoblastic leukemia (ALL). The Company determined that the time allowed in the CHMP procedure was not sufficient to provide the additional data requested in the CHMP’s Day 180 List of Outstanding Issues (LOI). The Company intends to resubmit an MAA around mid-2017.

Following positive efficacy and safety results from the completed European Phase 2/3 pivotal study in patients with relapsed and refractory ALL, ERYTECH submitted an MAA for GRASPA in September 2015. The Company received the Day 180 LOI in September 2016 and has been in discussion with the Rapporteur/Co-rapporteur and the CHMP to provide the requested additional data regarding the comparability between the old and new form of asparaginase encapsulated in GRASPA and the development of a new immunogenicity assay, as well as the pharmacodynamics effects of eryaspase. Given the fact that the generation of these additional data will require more time than allowed in the CHMP’s approval procedures, the Company has notified the CHMP of the withdrawal of the application at this time. The Company intends to resubmit the MAA mid-2017, as soon as the newly generated data are available.

“It is disappointing that assembling the data necessary to properly address the remaining questions is requiring longer time than we were actually granted at this stage. Our pivotal trial demonstrated improved clinical outcome and an excellent safety profile with eryaspase compared to native asparaginase. We are committed to pursuing regulatory approval for GRASPA and intend to work closely with our investigators and advisors to generate the additional information requested and to resubmit an MAA next year” said Iman El-Hariry, Chief Medical Officer of ERYTECH.

“The decision to withdraw at this stage was not an easy one, but does not change our commitment to bringing eryaspase to the market.” comments Gil Beyen, ERYTECH’s Chairman and Chief Executive Officer. “We believe we have generated strong clinical data in our different programs of eryaspase, and we continue to execute our plans towards making the product available to patients with aggressive forms of cancer, such as acute lymphoblastic leukemia, acute myeloid leukemia and pancreatic cancer. We are not aware of any safety issues and our other clinical trials are not affected. We will continue to pursue our planned clinical strategy in ALL and AML in close collaboration with our European partner Orphan Europe (Recordati Group)”.

About ERYTECH and eryaspase (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 plans to pursue regulatory approvals for its lead product candidate, eryaspase, also known as ERY-ASP or under the trade name GRASPA®, having achieved positive efficacy and safety results from its completed Phase 2/3 pivotal clinical trial in Europe in children and adults with relapsed or refractory ALL. ERYTECH also has an ongoing Phase 1 clinical trial of eryaspase in the United States in adults with newly diagnosed ALL, and a Phase 2b clinical trial in Europe in elderly patients with newly diagnosed AML, each in combination with chemotherapy. ERYTECH believes that eryaspase also 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.

Eryaspase 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. ERYTECH produces eryaspase 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 eryaspase 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. The European Medicines Agency (EMA) and the U.S. Food and Drug Administration (FDA) have granted orphan drug designations for eryaspase for the treatment of ALL, AML and pancreatic cancer.

In addition to eryaspase, ERYTECH is developing two other product candidates that focus on using encapsulated enzymes to induce tumor starvation. The company is also exploring the use of its ERYCAPS platform for developing cancer immunotherapies and enzyme replacement therapies.

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).
