Precision BioSciences and Tiziana Life Sciences announce exclusive license agreement to evaluate Foralumab

Latest pharma Update

Precision BioSciences, Inc., a clinical-stage biotechnology company developing allogeneic CAR T and in vivo gene correction therapies with its ARCUS genome editing platform, and Tiziana Life Sciences plc (Nasdaq: TLSA / LSE: TILS), a clinical-stage biotechnology company focused on innovative therapeutics for oncology, inflammation, and infectious diseases, today announced an exclusive license agreement to explore Tiziana’s Foralumab, a fully human anti-CD3 monoclonal antibody (mAb), as an agent to induce tolerance of allogeneic CAR T cells to potentially improve the clinical outcome of CAR T cell therapy.

 The Cluster of Differentiation (CD) 3 is a receptor on effector T cells and an anti-CD3 antibody, such as foralumab, has the potential to eliminate or tolerize patient effector T cells. Precision’s manufacturing process, which uses ARCUS to knock out the TRAC gene and implements a CD3-depletion step, produces allogeneic CAR T candidates that are >99.9% CD3-negative. Thus, an anti-CD3 antibody, such as foralumab, might be used to enable the CAR T cells to expand, proliferate, and persist to maximize long term clinical benefits.

Under the terms of the agreement, Precision gains an exclusive license to use Foralumab as a lymphodepletion agent in conjunction with its allogeneic CAR T therapeutics for the treatment of cancers. Precision will be responsible for the development, commercialization, and costs for use of Foralumab, and Tiziana will receive upfront payment, certain milestone payments, and royalties for Foralumab.

“We are building out an allogeneic CAR T platform with editing strategies and novel conditioning regimens, such as a lympho depleting agent like Foralumab, for a broad range of hematologic malignancies and solid tumors,” said Alan List, M.D., Chief Medical Officer at Precision BioSciences. “By combining Precision’s know-how in constructing novel CAR T products with novel conditioning regimens, we will explore this approach to potentially improve durability of clinical responses to our therapeutic platform.”

“We’re pleased to offer Precision the exclusive opportunity to explore Foralumab, our fully human anti-CD3 monoclonal antibody, for use as a potential lymphodepletion strategy with their allogeneic CAR T programs,” said Kunwar Shailubhai, Chief Executive Officer and Chief Scientific Officer of Tiziana Life Sciences. “While CAR T therapies have been clinically successful, relapse rates remain high, which continues to limit broad utility. We are impressed with Precision’s novel approaches to CAR T development, offering the potential for a meaningful off-the-shelf solution. Further, given Precision’s approach to manufacturing that produces CAR T cells virtually CD3-negative, we believe use of Foralumab as a lymphodepletion or tolerizing agent has the potential, either alone or in combination with other co-stimulatory molecules, to improve the long-term success of CAR T in cancer treatment.”
