Big picture - Why invest in Humanigen Inc
Humanigen Inc Snapshot
Derived from the company's Humaneered® platform, lenzilumab, ifabotuzumab and HGEN005 are monoclonal antibodies with first-in-class mechanisms. Our lead monoclonal antibody asset, lenzilumab, targets soluble GM-CSF and has been demonstrated to significantly reduce neurotoxicity and prevent cytokine release syndrome associated with CAR-T cell treatment in a proprietary human xenograft model while at the same time increasing CAR-T cell proliferation and effector functions. We are poised to begin clinical trials with lenzilumab for prophylaxis of neurotoxicity and cytokine release syndrome in combination with the leading CAR-T cell therapies. Ifabotuzumab, which targets Eph receptor A3 (EphA3), is being developed as a potential treatment for glioblastoma multiforme (GBM) and other deadly cancers, as well as a backbone for a novel CAR-T construct and as an antibody drug conjugate (ADC). HGEN005, which targets human epidermal growth factor-like module containing mucin-like hormone receptor 1 (EMR1), has potential to treat eosinophilic diseases and is being developed as a novel CAR-T construct for eosinophilic leukemia.
Monoclonal Antibody to Improve CAR-T Safety and Efficacy
Lenzilumab is a Humaneered® recombinant monoclonal antibody that neutralizes soluble granulocyte-macrophage colony-stimulating factor (GM-CSF) a critical inflammatory cytokine. GM-CSF is an upstream driver in the paths of multiple inflammatory diseases. Specifically, new science demonstrates that GM-CSF is the key initiator of inflammatory side-effects, neurotoxicity and cytokine release syndrome, associated with chimeric antigen receptor T-cell (CAR-T) cancer therapy.
Monoclonal Antibody/CAR-T Construct for the Treatment of Cancers
Ifabotuzumab is a first-in-class, Non-Fucosylated Humaneered® monoclonal antibody targeting the EphA3 receptor tyrosine kinase.
TARGETING CANCER VASCULATURE
Ifabotuzumab is unique in its potential to attack tumors at their source by killing tumor stromal cells that protect them and the vasculature that feeds them without killing normal cells. This unique combination of activities may provide the potential to generate durable responses.
Eph and ephrin proteins are critical to fetal development and vasculogenesis. EphA3 is not expressed in normal adult tissue but is thought to be important for the creation of the cancer stem cell compartment including stromal cells that surround and protect cancers and the tumor vasculature that feeds cancers. EphA3 is highly expressed in the tumor vasculature in cancers of the brain, kidney, and bladder in addition to melanoma. Glioblastoma multiforme (GBM) is the most common form of brain cancer and the most deadly. Targeting other antigens expressed by GBM such as IL-13Ra2 and EGFRvIII is associated with the development of antigen loss variants and there are safety concerns targeting HER2 given is expression in normal adult tissue. EphA3 is increasingly being recognized as therapeutic target given its lack of expression in normal adult tissues and its expression on bone marrow derived stromal cells that support the cancer’s growth and metastatic potential.
The first patients have been dosed in an ifabotuzumab clinical trial of patients with glioblastoma multiforme (GBM) at the Olivia Newton-John Cancer Research Institute in Australia. The trial is an Investigator-Sponsored Phase 1 trial with a radiolabeled imaging component in GBM. According to the investigators, the trial will seek to confirm the safety of ifabotuzumab and potentially determine the best dose to effectively penetrate brain tumors. The investigators expect about 12 patients to participate in the trial, for which eligibility criteria are recurrent GBM and receipt of only one type of chemotherapy for disease recurrence.
Humanigen is also developing ifabotuzumab as an antibody-drug conjugate (ADC) and as a CAR-T construct with a leading medical center in the U.S.
Monoclonal Antibody/CAR-T Construct for the Treatment of Eosinophilic Diseases
HGEN005 is a first-in-class Humaneered® monoclonal antibody targeting human epidermal growth factor-like module containing mucin-like hormone receptor 1 (EMR1).
ELIMINATING EOSINOPHILS IN TISSUE
HGEN005 has the cutting-edge potential to demonstrate superior efficacy to treat eosinophilic diseases due to its selectivity to hit the right target and its penetration to deplete eosinophils in tissue. A major limitation of current eosinophil-targeted therapies is incomplete depletion of tissue eosinophils and/or lack of cell selectivity.
Eosinophils are a type of white blood cell. If too many are produced in the body, chronic inflammation and tissue and organ damage may result. The origin and development of eosinophilic disorders is mostly due to eosinophils infiltrating tissue.
EMR1 is expressed exclusively on eosinophils, making it an ideal potential target for the treatment of eosinophilic disorders. Regardless of the eosinophilic disorder, mature eosinophils express EMR1 in tissue, blood and bone marrow in patients with eosinophilia.
In pre-clinical work, eosinophil killing was enhanced in the presence of HGEN005 and immune effector cells. Evidence shows HGEN005’s anti-EMR1 activity could selectively target and safely eliminate eosinophils in vivo in a primate model.
Thus, HGEN005 offers promise in a range of eosinophil-driven diseases, such as:
- eosinophilic leukemia
- eosinophilic asthma
- eosinophilic esophagitis
- eosinophilic granulomatosis with polyangiitis.
HGEN005 is another plank in our growing platform of CAR-T therapies. Because of its high selectivity, HGEN005 has significant potential incorporated into a CAR-T construct. Discussions are underway with a leading center in the U.S. to develop a series of CAR constructs based on HGEN005 and to explore further pre-clinical testing in eosinophilic leukemia, an orphan condition with significant unmet need.
