Precision BioSciences, Inc. announced that the U.S. Food and Drug Administration (FDA) has accepted the Investigational New Drug (IND) application for PBCAR19B, a next-generation, stealth cell, CD19 product candidate for patients with relapsed/refractory (R/R) Non-Hodgkin Lymphoma (NHL). The Phase 1 study will be a non-randomized, open-label, single-dose, dose-escalation and dose-expansion study deigned to evaluate the safety and clinical activity of PBCAR19B at increasing flat dose levels (2.7 x 108 - 8.1 x 108 CAR T cells) in patients with R/R NHL. The primary objective of the study is to identify the maximum tolerated dose and any dose-limiting toxicities.
