Study Demonstrates that GM-CSF Blockade in Combination with Chimeric Antigen Receptor T Cell Therapy (CAR-T) Prevents the Onset and Severity of Neurotoxicity and Cytokine Release Syndrome
BURLINGAME, Calif., Aug. 20, 2018 (GLOBE NEWSWIRE) -- Humanigen, Inc., (OTCQB: HGEN) (“Humanigen”), a biopharmaceutical company developing cutting-edge CAR-T optimization and oncology treatments, today announced positive topline results from a preclinical study demonstrating that use of the Company’s proprietary anti-GM-CSF antibody, lenzilumab, along with CD19 targeted chimeric antigen receptor T-cell therapy (CART19) reduces neurotoxicity (NT) and cytokine release syndrome (CRS) and enhances CART19 proliferation and effector functions.
A complete data set from the study has been submitted for presentation to the 2018 Annual Meeting of the American Society of Hematology, to be convened in December. “This is the first time it has been demonstrated that the spectrum of toxicities seen in CART19 clinical trials can be effectively prevented in vivo,” said Dr. Cameron Durrant, chief executive officer of HGEN. “We anticipate a highly impactful presentation and believe the totality of this data are very compelling and implicate GM-CSF as the key trigger in the NT and CRS cytokine cascade. We are committed to bringing lenzilumab forward in the near term to help CAR-T cell therapy realize its full potential.”
