INmune Bio Inc. Publishes Novel Biology on Natural Killer Cancer Immunotherapy INKmune™ in the Journal for ImmunoTherapy of Cancer
Publication of detailed analysis on INKmune biology compared to cytokine stimulated cells demonstrates important anti-tumor memory like NK cell characteristics
BOCA RATON, Fla., July 23, 2024 (GLOBE NEWSWIRE) -- -- INmune Bio Inc. (NASDAQ: INMB) (the “Company”), a clinical-stage inflammation and immunology company developing treatments that harness the patient’s innate immune system to fight disease, announced the publication of our landmark paper in Journal Immunotherapy of Cancer co-authored by Mark Lowdell, PhD, INmune’s Chief Scientific Officer, titled, “ Proteomic and phenotypic characteristics of memory-like Natural Killer cells for cancer immunotherapy.” Link to paper: https://jitc.bmj.com/content/12/7/e008717
The study demonstrates that memory-like natural killer (mlNK) cells, generated by either cytokine or INKmuneTM priming, show increased cytotoxicity against multiple tumor types, offering promising potential for cancer immunotherapy. Importantly, while most studies are conducted on NK cells from healthy volunteers, this study demonstrated that mlNK from cancer patients are equally as potent as those generated from healthy volunteers further supporting INKmune’s in vivo treatment methodology. The research also provides new insights into the metabolic and physiological mechanisms underlying NK cell memory, paving the way for innovative treatments in both hematological malignancies and solid tumors.
“The study of NK cell biology is evolving rapidly. This is the first study to identify the unique characteristics of tumor killing memory like NK cells and points to ways to enhance their potential further for cancer immunotherapy,” said Mark Lowdell PhD, CSO of INmune Bio and inventor of INKmuneTM. “INKmuneTM priming increases proteins which protect NK cells in the hostile tumor microenvironment which is exciting for our ongoing clinical trial in metastatic castration-resistant prostate cancer. This research study, led by INmune Bio, was a commercial and academic collaboration over several years and we are delighted to see it published in a high impact, peer-reviewed scientific journal.”
Most significantly, this study is the first to demonstrate in vivo generation of mlNK cells; something which cannot be done with the cytokine cocktail used in vitro. The researchers successfully showed that these mlNK cells, primed by INKmuneTM, can be found in patients after treatment, a critical step in proving our claimed mechanism of action.
Additionally, the paper highlights the enhanced metabolic function of the NK cells primed by INKmuneTM, predicting improved performance in the tumor microenvironment (TME). “This research is particularly noteworthy as NK cell dysfunction in the TME is often due to impaired metabolism,” stated RJ Tesi, INmune’s CEO. “The findings suggest that INKmune priming can overcome these metabolic barriers, leading to more effective NK cell resposes against tumors.”
INmune Bio is currently conducting a trial of INKmuneTM in the treatment of metastatic castration-resistant prostate cancer. Preliminary results from that trial are expected later this year.
About INKmune™
INKmune™ is a pharmaceutical-grade, replication-incompetent human tumor cell line which conjugates to resting NK cells and delivers multiple, essential priming signals to convert the cancer patient’s resting NK cells into tumor killing memory-like NK cells (mlNK cells). INKmune™ treatment converts the patient’s own NK cells into mlNK cells. In patients, INKmune™ primed tumor killing NK cells have persisted for more than 100 days. These cells function in the hypoxic TME because due to upregulated nutrient receptors and mitochondrial survival proteins.
INKmune™ is a patient friendly drug treatment that does not require pre-medication, conditioning or additional cytokine therapy to be given to the patients. INKmune™ is easily transported, stored and delivered to the patient by a simple intravenous infusion as an out-patient. INKmune™ is tumor agnostic; it can be used to treat many types of NK-resistant tumors including leukemia, lymphoma, myeloma, lung, ovarian, breast, renal and nasopharyngeal cancer. INKmune™ is treating patients in an open label Phase I/II trial in metastatic castration-resistant prostate cancer in the US this year.
About INmune Bio Inc.
INmune Bio Inc. is a publicly traded (NASDAQ: INMB), clinical-stage biotechnology company focused on developing treatments that target the innate immune system to fight disease. INmune Bio has two product platforms that are both in clinical trials: The Dominant-Negative Tumor Necrosis Factor (DN-TNF) product platform utilizes dominant-negative technology to selectively neutralize soluble TNF, a key driver of innate immune dysfunction and a mechanistic driver of many diseases. DN-TNF product candidates are in clinical trials to determine if they can treat cancer (INB03™), Early Alzheimer’s disease and treatment-resistant depression (XPro™). The Natural Killer Cell Priming Platform includes INKmune™ developed to prime a patient’s NK cells to eliminate minimal residual disease in patients with cancer. INmune Bio’s product platforms utilize a precision medicine approach for the treatment of a wide variety of hematologic and solid tumor malignancies, and chronic inflammation.
