INmune Bio, Inc. Data at ASH Highlight Innovative Natural Killer Cell Therapeutic Platform Showing 100+ Day Persistence of Cancer Killing Memory Like NK Cells in Patients with AML/MDS Following Treatment with INKmune™
INmune Bio (NASDAQ: INMB) will present data on INKmune™ therapy for patients with MDS or AML at the American Society for Hematology Conference in New Orleans, from December 10-13. The study, conducted at Southampton University, shows INKmune's safety in 4 patients and indicates sustained NK cell activation in 3. Notably, one patient exhibited long-lasting tumor-killing memory-like NK cells. The trial continues to enroll participants in the UK and EU, with plans to expand to the US for solid tumor indications. Key cytokines associated with immune responses were significantly altered post-treatment.
- Data presentation at a major conference showcases promising results for INKmune therapy in treating AML/MDS.
- INKmune demonstrated safety in a small cohort with no serious adverse events reported.
- Sustained NK cell activation observed in 3 out of 4 patients, indicating potential efficacy.
- Long-lasting tumor-killing memory-like NK cells noted in one patient for over 100 days after treatment.
- Limited patient cohort (only 4 patients) restricts the generalizability of results.
- Presence of only one patient showing significant NK activation might raise concerns about broader efficacy.
Boca Raton, Florida, Dec. 08, 2022 (GLOBE NEWSWIRE) -- INmune Bio, Inc. (NASDAQ: INMB) (“INMB” or “the Company”), a clinical-stage immunology company focused on developing treatments that harness the patient’s innate immune system to fight disease will present data from UK patients with MDS or AML treated with INKmune™ at the annual American Society for Hematology (ASH) Conference held in New Orleans December 10th – 13th. The clinical team at Southampton University in the UK, led by Professor Kim Orchard, the past president of the British Society of Blood and Marrow Transplantation and Cellular Therapy, is the first author of the presentation.
The poster presents findings from patients who have received INKmune therapy for treatment of their AML/MDS and provides additional information on the biologic changes that occur in the patients’ NK cells after treatment with INKmune. Highlights include:
- INKmune safely administered to 4 patients without SAE/R.
- Demonstrable and sustained NK activation in 3 of the 4 patients. Patient 4 had a high level of disease with low numbers of NK cells of which more than half her NK cells were immature.
- Persistent tumor killing memory-like NK cells in the patient with MDS for more than 100 days.
- NK activation temporally associated with significant changes in systemic levels of key cytokines including Macrophage Inflammatory Proteins (MIP1-a and MIP1-b).
- INKmune™ activated NK cells show proteomic and metabolomic changes predictive of improved survival in the tumor microenvironment (TME).
“The treatment of these patients with advanced hematologic malignancies has produced proof-of-concept data for INKmune while expanding insight into the role of NK cells in controlling cancer,” said Dr. Mark Lowdell, CSO of INmune Bio. “The performance of INKmune primed NK cells in vivo has mirrored all of our in vitro data and the proteomics and metabolomics data increase our knowledge into INKmune™ mechanism of action. The increase in circulating MIP1-a and MIP1-b in our patients after INKmune is very exciting. MIP-1 cytokines promote anti-cancer immune responses by intra-tumoral monocytes and T cells and promote recruitment of immune cells into the tumor microenvironment. We believe these new insights will aid in reaching our ultimate goal of providing a more comprehensive therapy for these extremely poor prognosis patients.”
The Laurel Phase I trial continues to enroll patients in the UK and EU with two new sites in the process of opening recruitment. In addition, the Company is preparing to expand the INKmune™ program to the US in a solid tumor indication. The Company will make additional announcements regarding the solid tumor target and the timing of the clinical trial.
“Presentation of data at the most important hematologic cancer meeting is an honor. We hope this will be the first of many presentations on this promising program,” said RJ Tesi, MD, CEO of INmune Bio. “The ability of INKmune™ primed NK cells to survive and thrive in the hypoxic and immunologically hostile TME is unique. This biology makes a pivot to INKmune™ treatment of solid tumors an obvious next step in the platform’s growth.”
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 akin to treatment with at least three cytokines in combination. INKmune™ is stable at -80oC and is delivered by a simple IV infusion. The INKmune:NK interaction ligates multiple activating and co-stimulatory molecules on the NK cell and enhances its avidity of binding to tumor cells; notably those resistant to normal NK-mediated lysis. Tumor-primed NK (TpNK) cells can lyse a wide variety of NK-resistant tumors including leukemias, lymphomas, myeloma, ovarian cancer, breast cancer.
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™), Mild Alzheimer’s disease, Mild Cognitive Impairment 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.
