Precision BioSciences, Inc. is a clinical-stage biotechnology firm based in the United States, specializing in the creation of both in vivo gene editing solutions and ex vivo allogeneic CAR T-cell therapies. At its core is ARCUS, a proprietary genome editing platform designed to address and potentially cure genetic diseases. The company's portfolio also encompasses Ex vivo Allogeneic CAR T Immunotherapy, an innovative approach where specific immune cells, known as T-cells, are genetically modified outside the body to precisely identify and eliminate cancer cells. Among its prominent therapeutic candidates are: PBCAR0191, currently undergoing Phase 1/2a clinical trials for adult patients battling relapsed/refractory (R/R) non-Hodgkin lymphoma or R/R B-cell precursor acute lymphoblastic leukemia (B-ALL). PBCAR19B, an anti-CD19 CAR T candidate leveraging a "stealth cell" platform through a single-step gene edit, engineered to reduce the likelihood of chromosomal abnormalities. PBCAR269A, an investigational allogeneic CAR T immunotherapy formulated to target BCMA, intended for the treatment of R/R multiple myeloma. Precision BioSciences has strategically formed several collaborative alliances. These include an agreement with Les Laboratoires Servier for the development and commercialization of allogeneic chimeric antigen receptor T-cell therapies, aimed at various antigen targets, including hematological cancers beyond CD19, and solid tumors. The company is also partnering with Tiziana Life Sciences to assess foralumab, a fully human anti-CD3 monoclonal antibody, for its utility as a lymphodepleting agent in potential cancer treatments. Furthermore, a collaboration with iECURE, Inc. focuses on advancing ARCUS-based gene editing therapies. Established in 2006, Precision BioSciences, Inc. maintains its corporate headquarters in Durham, North Carolina.
