ERYTECH announces the publication of positive results from the Eryaspase phase 2 trial in hypersensitive ALL
in the British newspaper of Hematology
- The study confirms the potential of eryaspase (GRASPA®) as an attractive treatment option for acute lymphoblastic leukemia (ALL) patients with hypersensitivity to PEG-asparaginase
Cambridge, MA (USA) and Lyon (France), April 06, 2022 – ERYTECH Pharma (Nasdaq & Euronext: ERYP), a clinical-stage biopharmaceutical company developing innovative therapies by encapsulating therapeutic drug substances inside red blood cells, today Announces Results of Phase 2 Trial Sponsored by NOPHO eryaspase in ALL patients are now published in the British newspaper of Hematology.
The NOR-GRASPALL-2016 Phase 2 trial evaluated the safety and pharmacological profile of eryaspase in patients with ALL who previously experienced hypersensitivity reactions to pegylated asparaginase treatment. The trial was conducted by the Nordic Society of Pediatric Hematology and Oncology (NOPHO) at 21 clinical sites in the Nordic and Baltic countries of Europe and enrolled 55 patients. The main objectives of the trial were the activity and safety of the enzyme asparaginase. Both endpoints were met.
Eryaspase demonstrated sustained above-threshold asparaginase enzyme activity of >100 U/L at trough levels 14 days after the first infusion in 92.5% of patients. Eryaspase was generally well tolerated when added to chemotherapy, and almost all patients were able to receive planned courses of asparaginase (median of 5 doses per patient). Of the 55 patients, only 2 patients had a severe allergic reaction and discontinued treatment with eryaspase.
The principal researcher, dr. Birgitte Klug Albertsenassociate professor at Aarhus University Hospital, Denmark, commented, “I am recognizing that the editors of the British newspaper of Hematology selected our study for publication. The study demonstrated that eryaspasegiven as a convenient bi-weekly schedule, provides sustained asparaginase enzyme activity levelI above recommendation threshold for others Asparaginase treatments, few hypersensitivity reactions and is generally well tolerated in combination with chemotherapy. We conclude that andryaspase seems to be a promising treatment alternative for all patients with hypersensitivity to PEG-asparaginase.”
“We are proud to work with the NOPHO group in conducting this ALL study, and hope that the study results will provide the possibility of an alternative treatment for ALL patients with hypersensitivity to PEG- asparaginase.” said Dr. Iman El-Hariry, Medical Director of ERYTECH. “We have an ongoing dialogue with the US FDA regarding possible regulatory approval in this indication based on the NOPHO sponsored trial..”

On Acute lymphoblastic leukemia
Acute lymphoblastic leukemia (ALL) is a cancer of the blood and bone marrow that is the most common type of cancer in children in the United States and Europe. More than 13,000 cases are diagnosed in the United States and Europe each year, with the majority of patients being diagnosed
before the age of 20. Asparaginase has been an integral part of the treatment of ALL for many years, but is associated with treatment-limiting hypersensitivity in up to 30% of patients. Discontinuation of asparaginase therapy in patients with ALL has been associated with
lower event-free survival highlighting the need for additional asparaginase-based treatment options.
About ERYTECH and eryaspase (GRASPA®)
ERYTECH is a clinical-stage biopharmaceutical company developing innovative therapies based on red blood cells for severe forms of cancer and orphan diseases. Leveraging its proprietary ERYCAPS® platform, which uses novel technology to encapsulate drug substances within red blood cells, ERYTECH is developing a pipeline of product candidates for patients with high unmet medical needs. ERYTECH is primarily focused on the development of product candidates that target the altered metabolism of cancer cells by depriving them of the amino acids necessary for their growth and survival.
The Company’s lead product candidate, eryaspase, which consists of L-asparaginase encapsulated in donor red blood cells, targets the impaired asparagine and glutamine metabolism of cancer cells. Proof of concept of eryaspase as a cancer metabolism agent has been established in different trials in acute lymphoblastic leukemia (ALL) and pancreatic cancer. An investigator-sponsored Phase 2 (IST) trial evaluating the use of eryaspase in patients with ALL who developed hypersensitivity reactions to pegylated asparaginase recently reported positive results, based on which the Company intends to seek approval in the United States and potentially in other territories. The Company is also pursuing an investigator-sponsored Phase 1 clinical trial in first-line pancreatic cancer.
Eryaspase has received Fast Track Designation from the United States Food and Drug Administration (FDA) for the treatment of advanced pancreatic cancer and the treatment of patients with acute lymphoblastic leukemia (ALL) who have developed hypersensitivity reactions to pegylated asparaginase derived from E. coli. The FDA and the European Medicines Agency have granted eryaspase orphan drug status for the treatment of pancreatic cancer and ALL.
ERYTECH produces its product candidates for the treatment of patients in Europe at its GMP approved manufacturing site in Lyon, France, and for patients in the United States at its GMP manufacturing site in Princeton, New Jersey, USA. Eryaspase is not an approved drug.
ERYTECH is listed on the Nasdaq Global Select Market in the United States (ticker: ERYP) and on the regulated market of Euronext in Paris (ISIN code: FR0011471135, ticker: ERYP). ERYTECH is part of CAC Healthcare, CAC Pharma & Bio, CAC Mid & Small, CAC All Tradable, EnterNext PEA-PME 150 and Next Biotech indices.
