Enlivex Receives Notice of Allowance for U.S. Patent Application Covering the Use of Allocetra™ to Prevent Cytokine Release Syndrome in Patients Receiving CAR T Cell Therapy
Nes-Ziona, Israel, Sept. 06, 2022 (GLOBE NEWSWIRE) -- Enlivex Therapeutics Ltd. (Nasdaq: ENLV, the “Company”), a clinical-stage macrophage reprogramming immunotherapy company targeting diseased macrophages in patients with sepsis and solid tumors, today announced that the U.S. Patent and Trademark Office issued a Notice of Allowance for patent application number 15/551,284. Once issued, the resulting patent will provide Enlivex with added intellectual property (IP) protection through at least 2036 with claims covering methods of using Allocetra™ to inhibit or reduce cytokine release syndrome in patients undergoing chimeric antigen receptor (CAR) T-cell therapy. The Company expects that this new patent will be issued in the United States by the end of the first quarter of 2023.
Oren Hershkovitz, PhD, CEO of Enlivex commented, “We look forward to the anticipated issuance of this patent, which will broaden the robust IP portfolio protecting Allocetra™ and our various development programs. This IP portfolio is a key source of value for Enlivex, and we remain committed to its maintenance and continued expansion.”
CAR T cells are T cells that have been genetically engineered to include a receptor that allows them to specifically target and destroy cancerous cells. While several CAR T cell treatments were recently approved by the FDA in several cancer indications, such treatments have been associated, in many patients, with a side effect named cytokine release syndrome, which describes a collection of potentially severe or life-threatening symptoms that stem from over-activation of immune pathways. Preclinical data indicate that Allocetra™ has the potential to prevent or reduce cytokine release syndrome associated with CAR T-cell therapies.
ABOUT ALLOCETRA™
Allocetra™ is being developed as a universal, off-the-shelf cell therapy designed to reprogram macrophages into their homeostatic state. Diseases such as solid cancers, sepsis, and many others reprogram macrophages out of their homeostatic state. These non-homeostatic macrophages contribute significantly to the severity of the respective diseases. By restoring macrophage homeostasis, Allocetra™ has the potential to provide a novel immunotherapeutic mechanism of action for life-threatening clinical indications that are defined as "unmet medical needs", as a stand-alone therapy or in combination with leading therapeutic agents.
ABOUT ENLIVEX
Enlivex is a clinical stage macrophage reprogramming immunotherapy company developing Allocetra™, a universal off-the-shelf cell therapy designed to reprogram macrophages into their homeostatic state. Resetting non-homeostatic macrophages into their homeostatic state is critical for immune system rebalancing and resolution of life-threatening conditions. For more information, visit
