Precision BioSciences Presents Updated Interim Clinical Data at the ASH Annual Meeting

Precision BioSciences, Inc. (Nasdaq: DTIL), a genome editing company dedicated to improving life through the application of its pioneering, proprietary ARCUS® platform, today announced updated interim clinical data from the ongoing Phase 1 trial of its lead investigational off-the-shelf (allogeneic) chimeric antigen receptor (CAR) T cell therapy candidate, PBCAR0191, which targets the well characterized cancer cell surface protein CD19.

PBCAR0191 is being developed in collaboration with Servier, an international pharmaceutical company. Data will be presented by Bijal Shah, MD, Moffitt Cancer Center, at the 61st Annual Meeting of the American Society of Hematology (ASH) in Orlando, Florida, during a poster session from 6:00-8:00 p.m. ET today (Poster #4107, Hall B).

“We are very encouraged by the evidence of cell-mediated anti-tumor activity and objective tumor responses that we have observed in both NHL and B-ALL patients treated with PBCAR0191, in the context of a manageable adverse event profile,” said Chris Heery, MD, Chief Medical Officer of Precision BioSciences. “These data give us incremental confidence in our unique approach to allogeneic CAR T cell therapy, and we look forward to the potential of this therapy positively impacting the lives of more patients as the trial continues. At these still low dose levels, and using only mild lymphodepletion, it is remarkable to see anti-tumor activity in the majority of patients treated with PBCAR0191, including a durable response that lasted six months in one patient, and two complete responses. We have also seen preliminary evidence of dose dependent CAR T cell expansion and persistence, supporting our belief that cell persistence and clinical response is likely to increase as we increase dose level.”

“New treatment options are desperately needed for patients with advanced NHL and B-ALL who often undergo multiple cycles of therapy with limited clinical benefit,” commented Bijal Shah, MD, Moffitt Cancer Center. “These first-in-human data for PBCAR0191 suggest a tolerable safety profile and encouraging early evidence of clinical activity. Further study is required to determine durability of response at the current dose levels, as well as to establish safety and activity at Dose Level 3.”
