MUC4

INB03 increases uptake of deruxtecan, the immunotoxin associated with trastuzumab deruxtecan (T-DXd, ENHERTU®), in models of resistant MUC4 expressing HER2 positive breast cancer and increases the tumor killing immunology of the tumor microenvironment. Boca Raton, Florida, Nov. 29, 2023 (GLOBE NEWSWIRE) -- INmune Bio, Inc. (NASDAQ: INMB) (the “Company”), a clinical-stage immunology company focused on developing treatments that harness the patient’s innate immune system to fight disease, is presenting data on the use of INB03, a dominant-negative TNF inhibitor of soluble TNF (sTNF) in the treatment of high-risk MUC4 expressing HER2. Roxana Schillaci, Ph.D., of Instituto de Biología y Medicina Experimental in Buenos Aries, Argentina, will present her work at the 46th annual San Antonio Breast Cancer Symposium, which runs from December 5 to 9. “This work demonstrates another way that MUC4 expression causes resistance to HER2-targeted immunotherapy in women with resistant breast cancer," said Dr. Schillaci, who is also associated with CONICET and is senior author of this work. “MUC4 expression decreases the uptake of the antibody-drug conjugate T-DXd. Decreased T-DXd uptake results in less tumor killing in this tumor model and we suspect it plays an important role in relapse of disease after treatment with T-DXd.” The poster, titled, “Blocking soluble TNF to improve potency of trastuzumab-deruxtecan by increasing internalization and antitumor innate immune response in a resistant HER2-positive breast cancer model,” shows that INB03 improves the potency of T-DXd in a model of immunotherapy resistant HER2+ breast cancer. INB03 decreases resistance to T-DXd therapy in three ways. INB03 decreases MUC4 expression on the surface of the breast cancer cells increasing the ability of the antibody to bind to the HER2 target on the cancer cell. The combination of low-dose (1.5mg/kg) T-DXd+INB03 decreases tumor growth as much as full dose (5mg/kg) T-DXd alone suggesting increased binding of the immunotoxin to the cancer cell improves anti-tumor effects. INB03 increases internalization of T-DXd and converts the immunosuppressive TME into one that is more tumor-sensitive by polarizing tumor associated macrophages (TAM) from M2-like to M1-like phenotype with increased expression of IFNg. The poster concludes that the combination of INB03 may allow for lower doses of T-DXd to be effective in women with MUC4 expressing HER2+ breast cancer and that addition of INB03 may improve the response to T-DXd in women with resistant HER2+ disease. “Response rates in women treated with T-DXd is high, but relapse is common after a period of time. Identifying and overcoming resistance mechanisms to trastuzumab-based antibody-drug conjugates (ADC) will be a key to improving outcomes,” said RJ Tesi M.D., CEO of INmune Bio. “The body of work performed by Roxana Schillaci is clinically relevant. Resistance to trastuzumab immunotherapy can be predicted prospectively based on simple immunohistochemistry stains detecting tumor expression of MUC4. We hope that this simple step will allow women to receive a treatment that subverts a resistance mechanism without waiting for treatment failure. We further believe that this precision medicine approach should improve the treatment of women with MUC4 expressing breast cancers.” ENHERTU® is a registered trademark of Daiichi Sankyo Company, Limited. About INB03 INB03 is a DN-TNF inhibitor that neutralizes soluble TNF (sTNF) without affecting trans membrane TNF (tmTNF) or TNF receptors. Compared to currently available non-selective TNF inhibitors, INB03 preserves the immune response to cancer by decreasing immunosuppressive cells in the TME including TAM and MDSC while promoting recruitment of anti-tumor immune cells including cytolytic CD8+ lymphocytes, NK cells and anti-tumor macrophages. INB03 has completed an open label dose-escalation Phase I trial in patients with advanced cancer. In that trial, INB03 was found to be safe and well tolerated - no dose limiting toxicity was found. INB03 decreased blood biomarkers of inflammation in patients with advanced cancer. INMB is planning a Phase II trial that uses INB03 as part of combination therapy. About INmune Bio, Inc.

SIRP-CD47 is an innate immune checkpoint known as the “don’t eat me” signal. INB03 downregulates expression of SIRPα on macrophages promote increased cancer cell death by antibody dependent cellular phagocytosis (ADCP). Boca Raton, Florida, Oct. 30, 2023 (GLOBE NEWSWIRE) -- INmune Bio, Inc. (NASDAQ: INMB) (the “Company”), a clinical-stage immunology company focused on developing treatments that harness the patient’s innate immune system to fight disease, is presenting data on the use of INB03, a dominant-negative inhibitor of soluble TNF in the treatment of high-risk MUC4 expressing HER2+ breast cancer. Roxana Schillaci Ph.D. of Instituto de Biología y Medicina Experimental in Buenos Aries, Argentina, will present her work at the 38th annual Society of Immunotherapy in San Diego, California which runs from November 1-4. The poster entitled “INB03: a new immune checkpoint inhibitor that reprograms polarization and promotes ADCP in human macrophages,” shows that INB03 is an innate immune checkpoint inhibitor working through the SIRPα-CD47 pathway to promote ADCP. SIRPα is a surface protein expressed by macrophages that binds to CD47 expressed by tumor cells. SIRPα-CD47 is known as the “don’t eat me” signal that prevents phagocytosis of tumor cells and promotes resistance to immunotherapy. INB03 downregulates SIRPα expression to eliminate the “don’t eat me signal” and promote ADCP. Inhibition of the SIRPα-CD47 pathway has focused predominately on targeting CD47 with anti-CD47 therapeutics. Targeting SIRPα may provide differentiated pharmacokinetic, safety, and efficacy pro “Macrophages play an important role in the control of tumors, but cancer cells have developed very efficient ways to evade attack by the patient’s immune system,” said Roxana Schillaci, Ph.D. of CONECIT and senior author of this work. “TNF promotes expression of SIRPα on macrophages that bind to CD47 on tumor cells to prevent ADCP. Neutralization of sTNF with INB03 downregulates the expression of SIRPα to promote ADCP that should help control tumor growth and prevent resistance to immunotherapy.” The research presented in the poster examines animal models and human macrophages. INB03 neutralizes sTNF, repolarizing tumor protecting M2 macrophages to M1 anti-tumor macrophages, enhances ADCP with trastuzumab, and reduces SIRPα expression. In mice with trastuzumab resistant breast cancer, INB03 treatment polarizes splenic and tumor-infiltrating macrophages to M1 type macrophages that phagocytize tumor cells and decreased immune checkpoint expression (PD-L1, TIM3, LAG3) in tumor-infiltrating CD8+ T cells. RJ Tesi MD, CEO of INmune Bio, stated that, “a new therapeutic strategy for treating cancer is to improve the function of tumor-infiltrating macrophages. DN-TNF has been shown to improve macrophage phagocytosis in models of AD, MS, DMD, and cancer.” Microglia are tissue-based macrophages of the brain, while tumor macrophages are the phagocytic cells of the tumor microenvironment (TME). In disease, soluble TNF depresses macrophage phagocytic function, resulting in neurodegeneration, synaptic dysfunction, and demyelination in the brain or tumor growth and resistance to cancer immunotherapy. DN-TNF neutralizes sTNF and returns phagocytic function to normal. In neurodegenerative diseases, DN-TNF promotes microglial phagocytic function to promote remodeling and repair by decreasing neurodegeneration, improving synaptic plasticity, and promoting remyelination. In cancer, DN-TNF repolarizes immunosuppressive macrophages into tumor-killing macrophages and promotes ADCP. In both cases, normalizing phagocytic function should allow for therapeutic benefits.

Company to Host Conference Call Today, August 7, at 4:30pm ETBOCA RATON, Fla., Aug. 07, 2023 (GLOBE NEWSWIRE) -- INmune Bio Inc. (NASDAQ: INMB) (the “Company”), a clinical-stage immunology company focused on developing treatments that harness the patient’s innate immune system to fight disease, today announces its financial results for the quarter ended June 30, 2023 and provides a business update. Q2 2023 Corporate Highlights: DN-TNF Platform Highlights (XPro™ and INB03™): AD02 blinded randomized program in patients with Early Alzheimer’s Disease (AD) continues to enroll in Australia and Canada. The company is actively pursuing other regulatory venues to expand the clinical trial footprint. Discussions with the FDA have provided a clear pathway to lifting the clinical hold before the end-of-year.Announced expansion of novel MRI biomarker data to include gray matter. Gray matter, the portion of the brain containing nerve cell bodies, has historically been the focus of Alzheimer’s disease research and drug development. Previous MRI biomarker analysis from patients receiving XPro™ for treatment of AD has demonstrated early changes in white matter that predict presence of neuroinflammation and response to XPro™ therapy. The new data, reported at the annual Alzheimer’s Association International Conference (AAIC) in Amsterdam, Netherlands in July, demonstrates improvement in gray matter in patients with AD. The results demonstrate a dose dependent enhancement in gray matter measures in the brain in AD patients treated with XPro™. The data confirm that neuroinflammation affects white and gray matter of the brain. Treatment with XPro™ resulted in improvements in both white and gray matter microstructural elements that may predict improvements in cognition. The data further validate the biomarker package associated with the on-going Phase II trial in patients with Early AD. Presented data in early July at the 16th European Meeting on Glial Cells in Health and Disease in Berlin that show that XPro™ promotes remyelination by affecting astroglial and microglial biology. Myelin is a specialized lipid produced by oligodendrocytes that forms the myelin sheath of axons. Axons are the projections that allow neurons to communicate with each other and with other tissues such as muscle, skin, retina, nose, and the ear for sight, smell, and hearing respectively. An intact and healthy myelin sheath is necessary for axons to allow neurons to communicate with each other and work properly. Drug therapies to prevent demyelination are available, but there are no therapies that promote remyelination. Therapies that promote remyelination will be needed to effectively treat many neurodegenerative diseases and is increasingly recognized as part of the pathology associated with Alzheimer’s disease. The Company plans a webinar on highlighting the importance of remyelination therapy in patients with MS and AD before the end-of-year.Presented additional data on combination of INB03™ with trastuzumab-deruxtecan (Enhertu™, TDxd) at the American Association for Cancer Research (AACR) annual scientific meeting in April showing that triple negative breast cancer (TNBC) often express MUC4. MUC4-expressing cancers, breast cancer, HER2+ breast cancer, TNBC, gastric, and pancreatic cancer, are candidates for combination therapy with DN-TNF. In pre-clinical models, INB03™ reduced MUC4 expression to decrease resistance to immunotherapy including tyrosine kinase inhibitors (TKI), trastuzumab and TDxd. A pSar DN-TNF compound with new composition-of-matter IP is in animal testing in preparation for a strategic partnering program in oncology. The polysarcosine (pSar) DN-TNF program converts XPro™ from a single drug into a DN-TNF drug platform. Polysarcosine is a novel half-life extender that effectively replaces the PEG half-life extender used in XPro™. The pSar program is an essential part of INmune Bio’s business development efforts. XPro™ has been designated for the CNS programs, including AD, TRD, ALS and other neurological diseases. The pSar program provides at least three new DN-TNF biologics that are eligible for composition-of-matter IP and have unique biologic characteristics that allow partnering DN-TNF opportunities beyond CNS, such as oncology (INB03™), Duchenne’s Muscular Dystrophy (DMD), and other disease indications. Each drug is a novel DN-TNF compound that will require a unique development program. INKmune™ Platform: IND cleared by the Food & Drug Administration (FDA) in May for INKmune™ for a Phase I/II open label trial in metastatic Castration-Resistant Prostate Cancer (mCRPC). The trial is expected to enroll the first of 30 patients in the final quarter of 2023. Patients will receive three infusions of INKmune™ as out-patient treatment during the six-month trial. Three doses of INKmune™ are being tested in a modified Bayesian Phase I/II trial to answer four questions: Is INKmune™ safe in patients with mCRPC?What dose of INKmune™ should be used in a blinded randomized pivotal trial in men with mCRPC?How long can the effects of INKmune™ be sustained, (Determined by measuring tumor killing NK cells in the blood called memory like NK cells).Is there a tumor response to INKmune™ therapy? Measures of tumor response include blood PSA and tumor DNA levels in the patient’s blood and PMSA PET scan. The results of the open label study should allow the Company to design a pivotable trial. LAUREL, the INKmune™ trial in high risk MDS and AML has opened a third clinical site in Athens, Greece. The site is screening patients and expects to enroll patients soon. Changing management of high risk MDS patients in the UK has resulted in screen failures. The cause of these screen failures has been identified and addressed to help increase recruiting of patient into LAUREL. The Company is seeking to modify the trial enrollment criteria to increase the pool of potential patients to drive recruitment.CSO Dr. Mark Lowdell gave the opening plenary presentation in the Presidential Session at the annual International Society of Cell & Gene Therapy (ISCT) where he presented the scientific discovery of INKmune™ and development to clinical trials. His talk highlighted that NK cells primed by INKmune™ have the ability to alter their phenotype to a cancer-killing population of memory-like NK cells that differ from single-cytokine or multiple-cytokine (IL-12, IL-15, IL-18) primed NK cells. This innovation avoids the cost and complications associated with cytokine therapy and produces NK cells ideally suited for attacking cancer. Upcoming Events and Milestones: Top-line results for the Phase II XPro™ trial for treatment of neuroinflammation as a cause of Alzheimer’s Disease are expected towards the end of 2024.Initiate a Phase II trial of XPro™ in patients with Treatment-Resistant Depression upon resolution of the ongoing FDA manufacturing review.Webinar on using XPro™ to promote remyelination in AD and MS before end-of-year.Additional open-label Phase I trial data of INKmune™ in high-risk MDS/AML in 2023.Opening of a Phase I/II trial in a prostate cancer in the second half of 2023.
