Erytech Scraps Plans for Leukemia BLA
Erytech Pharma says it is no longer seeking approval for Graspa (L-asparaginase encapsulated in red blood cells) in hypersensitive acute lymphoblastic leukemia (ALL) following FDA feedback that requested additional clinical data. “In multiple clinical trials, Graspa showed promising results for patients, and we were encouraged by the dialog with the FDA and the fast track designation that we received for this indication last year,” the company says.
Erytech had been in discussions with FDA for seeking approval of Graspa in treating ALL patients who had previously experienced hypersensitivity reactions to pegylated asparaginase therapy. In 2021, the company confirmed its intention to submit a BLA, subject to the submission of additional requested information and agreement on an Initial Pediatric Study Plan (iPSP).
“The company recently received feedback from the FDA on its iPSP, submitted in July 2022,” it says. “After thorough evaluation of this feedback, which included a new request for additional data, and taking into account the changing competitive landscape in the treatment of hypersensitive ALL, the company has determined that it is in the best interests of the company and its shareholders to no longer seek approval for Graspa in ALL and to focus its resources on its preclinical programs and strategic partnering activities.”
