EHA 2021 – allo hints for Celyad while Autolus chases CD19
Two years after spelling out its off-the-shelf Car-T ambitions Celyad has some early human data to go on. A presentation at the upcoming European Hematology Association meeting is set to detail the first multiple myeloma patients given CYAD-211, an allogeneic anti-BCMA construct that uses shRNA to silence endogenous T-cell receptors without gene editing. An abstract released this week shows one partial remission among two fifth-line subjects, with – importantly – no graft-versus-host disease in either. At the June 11 EHA session analysts hope to see data on further patients, perhaps at a higher cell dose. Another cell therapy player, Autolus, spiked this week on continued promise from its Car-T asset, Auto1, with its EHA abstract showing 100% complete remission in indolent lymphoma, and a remarkably low rate of neurotoxicity and cytokine release. Still, this is one of a multitude of projects targeting CD19. Investors are also keenly awaiting data at EHA from Forma’s FT-4202, a mechanistic rival to Agios’s mitapivat that impressed at Ash, though for now the biggest beneficiary of EHA appears to have been Curis.
