LYON, France--(BUSINESS WIRE)--Mar. 2, 2017-- Regulatory News:

ERYTECH Pharma (Paris:ERYP) (ADR:EYRYY) (Euronext Paris: ERYP), the clinical-stage biopharmaceutical company developing innovative therapies for rare forms of cancer and orphan diseases based on its proprietary ERYCAPS platform, encapsulating therapeutic drug substances inside red blood cells, today provided a business update and reported its financial results for the year ended December 31, 2016.

“In 2016, we made important progress moving our pipeline forward despite our decision to withdraw and resubmit our European Marketing Authorization Application for GRASPA. We are committed to bringing GRASPA to the market and continue to make significant strides in pursuing its first regulatory approval,” said Gil Beyen, Chairman and CEO of ERYTECH. “Our team is working diligently to provide the requested additional data to the CHMP and we plan to resubmit our MAA this summer. In addition, we presented important new findings related to the mechanism of action of GRASPA, as well as new preclinical data further supporting the anti-tumor activity of our new product candidate erymethionase (ERY-MET) in preclinical models. Looking ahead to 2017 we expect to reach several important milestones, most notably the results of our Phase 2 studies in pancreatic cancer and AML, the resubmission of the MAA for ALL, and the initiation of new trials. We strengthened our balance sheet with a successful private placement in the fourth quarter of 2016 and have the capacity to execute on our key strategic objectives for 2017. We strongly believe 2017 will be another transformative year in support of our mission of advancing novel anti-cancer therapies using our ERYCAPS technology for the benefit of patients in need.”

Full Year and Recent Business Highlights

• In November 2016, ERYTECH withdrew its Marketing Authorization Application (MAA) for eryaspase (GRASPA) for the treatment of relapsed and refractory ALL. The Company recognized that the time allowed in the CHMP procedure was not adequate to provide the additional data needed to answer the remaining questions in the CHMP’s Day 180 List of Outstanding Issues (LOI). The company is working toward collecting the data regarding comparability between the old and new forms of asparaginase encapsulated in GRASPA and the development of a new immunogenicity assay, as well as the pharmacodynamics effects of eryaspase. ERYTECH expects to resubmit the MAA this summer. The re-submission process has been initiated and interactions with the EMA and CHMP are being organized.
• The US Phase 1 dose-escalating study of eryaspase in first line adult ALL is progressing and is now expected to reach its recommended Phase 2 dose in mid-2017, after which the company intends to discuss further development plans with the FDA.
• The company is continuing to provide access to eryaspase under its expanded access program (EAP) in France, treating patients who cannot tolerate any of the available asparaginase products. Some patients have also been treated on a compassionate use basis, both in Europe and the US. The Company is also discussing with several investigators the potential for conducting investigator-initiated studies as a means to provide eryaspase to patients suffering from ALL.
• During the third quarter of 2016, complete enrollment was reached in the Phase 2b study with eryaspase in first line AML patients and in the Phase 2 study of eryaspase in second line metastatic pancreatic cancer. Respectively 123 and 141 patients have been treated. Reporting of the primary results of the pancreatic cancer study is expected by the end of Q1 2017. Results of the AML study are expected by the end of the year.
• In January 2017, ERYTECH presented findings from preclinical studies demonstrating strong tumor inhibiting activity of its new product candidate erymethionase (or ERY-MET) in a murine model of human gastric adenocarcinoma. Previous studies had also demonstrated erymethionase as a tumor starvation agent in glioblastoma mouse models.
• Preclinical development programs leveraging the use of the ERYCAPS encapsulation technology in immuno-oncology (ERYMMUNE) and enzyme therapies for certain metabolic diseases (ERYZYME) are progressing. Further proof of concept data is expected in the second half of this year.
• During 2016, the Company strengthened its board of directors and its executive management through the appointments of Allene Diaz as an independent board member, Alexander Scheer as Chief Scientific Officer (CSO) and Jean-Sébastien Cleiftie as Chief Business Officer (CBO). All three bring tremendous experience in the biopharmaceuticals field. Allene Diaz currently serves as Senior Vice President, Global Commercial Development at TESARO Inc. after having served for more than 20 years in senior executive functions at Merck Serono, EMD Serono, Amylin Pharmaceuticals, Cancervax Corporation, Biogen Idec, Pfizer and Parke-Davis Pharmaceuticals. Alexander was the Head of Research at Pierre Fabre, and Jean-Sébastien Cleiftie was Associate Vice-President, Global Business Development & Licensing at Sanofi before joining ERYTECH.

Full Year 2016 Financial Results

• ERYTECH’s key financial figures for the full year of 2016 compared with the same period of the previous year are summarized below:

Net loss for the full year 2016 was €22.0 million, compared to €15.0 million in 2015. The €7.0 million increase was primarily due to the €8.2 million increase in operating expenses, primarily due to the increase in clinical and regulatory development expenses, related to ongoing clinical programs in ALL, AML and Pancreatic cancer, the continuation of regulatory developments in Europe and the preparation of further clinical programs. R&D expenses also include pre-clinical developments on additional product candidates and the expansion of the ERYCAPS platform to other modes of action for immune therapies and enzyme-related therapies. The increase in operating expenses was partially offset by an increase in operating income.

• R&D expenses increased by €9.0 million. The increase was primarily the result of a €8.0 million increase in consumables and third-party services related to pre-clinical programs and clinical trials conducted in 2016 and a €1.4 million increase in personnel expenses due to increasing headcount, including staffing of the company’s new U.S. office in Boston.
• G&A expenses decreased by €0.9 million. The decrease was mainly related to a €1.6 million decrease in share-based payments, while personnel expenses increased by €1.1 million and travel-related expenses increased by €0.4 million, a reflection of the broader international base of the company’s operations.
• The increase in expenses was partially offset by the €1.2 million increase in operating income, related to higher French research tax credits of €1.1 million, which reflected the increased effort in R&D activities, as well as a €0.1 million increase in non-refundable grants from Bpifrance for the TEDAC program.
• Financial income decreased by €0.1 million, mostly as a result of lower average interest rates on interest-bearing investments.
• In December 2016, ERYTECH completed a €10.0 million private placement with a group of qualified investors in the Unites States and Europe. 793,877 ordinary shares were issued in the private placement. The proceeds from the private placement will enable ERYTECH to further advance several key strategic initiatives related to the development of its lead product candidate, eryaspase (GRASPA®), as well as for working capital and general corporate purposes.
• As of December 31, 2016, ERYTECH had cash and cash equivalents totaling €37.7 million, compared with €45.6 million on December 31, 2015. Net cash utilization for the 12-month period ended December 31, 2016 was €8.0 million and included the €9.2 million net proceeds from the Company’s December 2016 private placement of ordinary shares. Excluding the December 2016 capital raise, total cash utilization in 2016 was €17.2 million, comprised of a €19.3 million net cash utilization in operating activities and capital expenditures, as a result of ERYTECH’s continued efforts to advance its research and development programs, as well as increased general and administrative expenses, and a €2.1 million increase in borrowings, including a €1.5 million bank loan to support the design of the next generation ERYCAPS platform and a €0.6 million net increase in conditional advances from Bpifrance.
• As of December 31, 2016, ERYTECH’s cash position of €37.7 million represented approximately a two-year cash runway with the current company’s structure and ongoing studies.

The consolidated financial accounts for the full year 2016, approved by the board of directors on March 1^st, 2017, are available on ERYTECH’s website (www.erytech.com).

About ERYTECH: 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 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).
