The purpose for the meeting was to discuss clinical, non-clinical and quality content and expectations for the Company’s potential BLA submission. Based on the discussion and the totality of the available information to the Company to date, ERYTECH believes its regulatory package can potentially support an approval of eryaspase in hypersensitive ALL patients. Pending successful completion of remaining steps, the Company anticipates submitting a BLA in the fourth quarter of 2021.
"We are encouraged by the interactive dialogue with the agency, and grateful for the feedback and guidance we received on a potential path to approval," said Gil Beyen, CEO of ERYTECH. "This is an important milestone for ERYTECH as it advances our lead product candidate eryaspase as an alternative treatment for ALL patients with hypersensitivity to PEG-asparaginase, while our Phase 3 trial in second line pancreatic cancer is nearing completion. If all goes well, we could be in a position to make this product candidate available to ALL and pancreatic cancer patients in the course of next year."
In December 2020, positive Phase 2 clinical results were presented by the Nordic Society of Pediatric Hematology and Oncology, at the 2020 American Society of Hematology (ASH) (Free ASH Whitepaper) annual meeting. Eryaspase, in combination with chemotherapy, administered every two weeks, provided a sustained asparaginase enzyme activity level, and was generally well tolerated with few hypersensitivity reactions.
About 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 US and Europe. More than 13,000 cases are diagnosed in the US and Europe each year with the majority of patients diagnosed before age 20. Asparaginase has been an integral component of ALL treatment for several years but is associated with treatment-limiting hypersensitivity in up to 30% of patients. Discontinuation of asparaginase therapy in ALL patients has been associated with inferior event free survival highlighting the need for additional asparaginase based treatment options.
