Cambridge, MA (U.S.) and Lyon (France), April 25, 2022– ERYTECH Pharma (Euronext Paris: ERYP - Nasdaq: ERYP), a clinical-stage biopharmaceutical company developing innovative therapies by encapsulating therapeutic drug substances inside red blood cells, today announced the sale of its U.S. manufacturing facility toCatalent, a leading contract development and manufacturing organization (CDMO) in advanced therapies.

Under the terms of an asset purchase agreement between ERYTECH and Catalent (the “APA”), Catalent agreed to acquire ERYTECH’s state-of-the-art commercial-scale cell therapy manufacturing facility in Princeton, New Jersey, for a total consideration of $44.5 million. ERYTECH’s current staff at the site of approximately 40 people will be offered Catalent’s employment.

The parties will also enter into a long-term supply agreement, under which Catalent will manufacture ERYTECH’s lead product candidate eryaspase (GRASPA®) for clinical and commercial supply in the United States. ERYTECH has a Phase 1 trial in first-line pancreatic cancer ongoing in the United States and is in a continued dialogue with the U.S. FDA regarding a potential BLA submission for GRASPA® in hypersensititve ALL, now targeted in the third quarter of 2022, subject to FDA agreement on remaining outstanding information requests.

Catalent will also offer their expertise in late-stage and commercial manufacturing of advanced therapy medicinal products with respect to product characterization, commercial production, regulatory inspections, and approvals.

ERYTECH’s Princeton facility is a 30,900 sqft cutting edge manufacturing facility, designed with the flexibility to expand to support various cell therapy production requirements and capacities. Catalent intends to expand the Princeton site and leverage ERYTECH’s experienced staff to manufacture a broader portfolio of cell therapies. ERYTECH will retain its manufacturing site in Lyon, France and its expertise and capabilities in manufacturing process science to continue innovating in cell therapy manufacturing.

“In Catalent we have found a great partner for the manufacturing of our innovative red blood cell derived products, and we believe that this strategic partnership will meet our long-term manufacturing needs in the United States,” commented Gil Beyen, Chief Executive Officer of ERYTECH, “As we are turning this important page for ERYTECH, I wish to thank our entire Princeton team very much for their talent and dedication in building and developing our flagship facility since its inception in 2018.ERYTECH will now further focus capital resources on the development of potentially transformative therapeutics for serious diseases.We are also continuing to evaluate further strategic options for the company, including additional partnerships and addition of complementary assets, through which we can leverage our ERYCAPS® platform and our development and manufacturing capabilities.”

“This acquisition is strategically important to Catalent’s commitment to support the development, clinical, and commercial supply of cell therapies to meet rapidly growing demand,” said ManjaBoerman, Ph.D., President, Catalent Cell & Gene Therapy. “The talented and experienced staff already employed at the facility, the capabilities it has in place, and the opportunity to quickly add further capacity on the same site, allows Catalent to expand rapidly to create a U.S. campus and center of excellence for cell therapy development and manufacturing that will serve customers around the world.”

ERYTECH reported cash and cash equivalents of €33.7 million ($38.1 million) as of December 31, 2021. Upon closing of the transaction, ERYTECH’s cash and cash equivalents are expected to be approximately €55 million ($60 million) with the addition of the $44.5 million (€40.8 million) purchase price payment. With a reduction in yearly cash disbursements of approximately $7.5 million related to running costs of the Princeton facility, this cash position is expected to fund ERYTECH’s operations under its current configuration to mid-2024.

About ERYTECH and GRASPA®

ERYTECH is a clinical-stage biopharmaceutical company developing innovative red blood cell-based therapeutics for severe forms of cancer and orphan diseases. Leveraging its proprietary ERYCAPS® platform, which uses a novel technology to encapsulate drug substances inside red blood cells, ERYTECH is developing a pipeline of product candidates for patients with high unmet medical needs. ERYTECH’s primary focus is on the development of product candidates that target the altered metabolism of cancer cells by depriving them of amino acids necessary for their growth and survival.

The Company’s lead product candidate, eryaspase (GRASPA®), which consists of L-asparaginase encapsulated inside donor-derived red blood cells, targets the cancer cells’ altered asparagine and glutamine metabolism. The proof of concept of eryaspase as a cancer metabolism agent was established in different trials in acute lymphoblastic leukemia (ALL) and pancreatic cancer. An investigator sponsored Phase 2 trial (IST) evaluating the use of eryaspase in ALL patients who developed hypersensitivity reactions to pegylated asparaginase recently reported positive results, based on which the Company intends to request approval in the United States and potentially other territories. The Company is also pursuing a Phase 1 investigator-sponsored clinical trial in first-line pancreatic cancer.

Eryaspase received Fast Track designation from the U.S. Food and Drug Administration (FDA) for the treatment of advanced pancreatic cancer and treatment of acute lymphoblastic leukemia (ALL) patients who have developed hypersensitivity reactions to E. coli-derived pegylated asparaginase. The FDA and the European Medicines Agency have granted eryaspase orphan drug status for the treatment of pancreatic cancer and ALL. Eryaspase is not an approved medicine.

ERYTECH produces its product candidates for treatment of patients in Europe at its GMP-approved manufacturing site in Lyon, France, and for patients in the United States through its long-term supply agreement with Catalent, operating from ERYTECH’s former GMP facility in Princeton, New Jersey, USA.

ERYTECH is listed on the Nasdaq Global Select Market in the United States (ticker: ERYP) and on the Euronext regulated market in Paris (ISIN code: FR0011471135, ticker: ERYP). ERYTECH is part of the CAC Healthcare, CAC Pharma & Bio, CAC Mid & Small, CAC All Tradable, EnterNext PEA-PME 150 and Next Biotech indexes.
