BRISBANE, CA, USA I April 16, 2018 I Humanigen, Inc. (OTCQB:HGEN), a biopharmaceutical company pursuing cutting-edge science to develop its proprietary monoclonal antibodies for immunotherapy and oncology treatments, today announced it has signed an agreement with The University of Texas MD Anderson Cancer Center to begin investigator-led research on lenzilumab and its potential to support chimeric antigen receptor T cell (CAR-T) therapy. Lenzilumab is a first-in-class Humaneered® recombinant monoclonal antibody that targets and is an antagonist of soluble granulocyte-macrophage colony-stimulating factor (GM-CSF).
Preclinical work assessing lenzilumab’s action on one of the mechanisms in the inflammatory cascade induced by CAR-T will proceed in parallel with a planned study that could potentially qualify as a registration study, testing lenzilumab as a potential prophylaxis for neurotoxicity induced by CAR-T therapy. Neutralization of circulating GM-CSF has the potential to blunt or prevent an inflammatory cascade that can result in serious and life-threatening CAR-T-induced side effects – neurotoxicity and Cytokine Release Syndrome.
“With this agreement, we are excited that the team at MD Anderson Cancer Center is beginning to investigate lenzilumab’s potential to make groundbreaking CAR-T therapy safer, better and more routine,” said Cameron Durrant, M.D., chairman and chief executive officer of Humanigen. “CAR-T science has moved quickly in the past few years with the two currently marketed CAR-T therapies having been approved based on single Phase 1/2 studies. We look forward to adding to the burgeoning, cutting-edge science studying lenzilumab as a potential critical CAR-T support therapy.”
The preclinical study will measure the ability of lenzilumab to block patient CD19-CAR-T cells-treatment-derived GM-CSF induction of human leukocyte antigen-DR (HLA-DR) expression on CD14+ monocytes. It will assess the inhibitory effect of lenzilumab on GM-CSF-induced HLA-DR expression on CD14+ cells, plus other phenotypic and functional monocyte assays.
About Lenzilumab
Lenzilumab is a first-in-class, novel Humaneered® recombinant monoclonal antibody designed to target and neutralize circulating granulocyte-macrophage colony-stimulating factor (GM-CSF), the myeloid inflammation factor involved in the recruitment of myeloid cells to a tumor and a central actor in leukocyte differentiation, autoimmunity and inflammation. There is also extensive evidence linking GM-CSF expression to serious and potentially life-threatening side effects in chimeric antigen receptor T-cell (CAR-T) therapy, such as neurotoxicity and Cytokine Release Syndrome (CRS). Humanigen is working with leading CAR-T experts to develop lenzilumab as a potential prophylactic treatment to minimize neurotoxicity associated with CAR-T cancer therapy. In addition, lenzilumab is currently being evaluated as a potential treatment for rare leukemias in a phase 1 trial (NCT02546284) in patients with chronic myelomonocytic leukemia (CMML) with additional potential in juvenile myelomonocytic leukemia (JMML), a rare pediatric cancer. In previous clinical trials, lenzilumab has shown to be safe and well-tolerated in more than 100 patients, including those with rheumatoid arthritis, asthma and healthy volunteers. It is a potent inhibitor of GM-CSF in vivo.
About Humanigen
Humanigen, Inc. is a biopharmaceutical company pursuing cutting-edge science to develop its proprietary monoclonal antibodies for immunotherapy and oncology treatments. Derived from the company’s Humaneered® platform, lenzilumab and ifabotuzumab are monoclonal antibodies with first-in-class mechanisms. Lenzilumab, which targets GM-CSF, is in development as a potential medicine to make CAR-T therapy safer and more effective, as well as a potential treatment for rare hematologic cancers such as chronic myelomonocytic leukemia (CMML) and juvenile myelomonocytic leukemia (JMML). Ifabotuzumab, which targets Ephrin type-A receptor 3 (EphA3), is being explored as a potential treatment for glioblastoma multiforme (GBM) and other deadly cancers, as well as a backbone for a novel CAR-T construct and bispecific antibody platform.
