Precision BioSciences Inc. (Nasdaq: DTIL), a clinical stage biotechnology company developing allogeneic CAR T and in vivo gene correction therapies with its ARCUS® genome editing platform, today announced encouraging progress on two strategies designed to optimize the durability of allogeneic CAR T therapy in patients with relapsed/refractory (R/R) non-Hodgkin lymphoma (NHL). The Company reported updated interim results from its Phase 1/2a study of PBCAR0191, the Company’s investigational, off-the-shelf, allogeneic CAR T cell therapy targeting CD19. As of May 21, 2021, 12 patients with R/R NHL were enrolled and evaluated for response to PBCAR0191 with enhanced lymphodepletion (eLD). The Company also reported preclinical data demonstrating the potential mechanism by which its investigational immune evading stealth cell, PBCAR19B, may avoid rejection by T cells and natural killer (NK) cells.
