INKmune? Platform:

• Announced that INKmune? demonstrates excellent safety and increased NK-Cell activity in first dosing cohort, in a Phase I/II trial (the “CaRe PC” trial) for men with metastatic Castration-Resistant Prostate Cancer (mCRPC). Blinded analysis of the monitoring blood samples from the first three patients showed changes in the phenotype and function of the patient’s NK cells. Although this is the lowest dose cohort, 2 of 3 patients showed an increase in circulating activated NK cells and all three showed increased NK cell function sustained for more than 40 days after the final INKmune? infusion. One patient showed a transient 21% decrease in PSA associated with the increase in NK cell activity and function.

• There have been 21 administrations of INKmune? in the mCRPC study given on an out-patient basis, with no significant adverse events including zero cases of cytokine release syndrome (CRS). Combining the experience with INKmune? from the MDS/AML and mCRPC trials, over 30 infusions of INKmune? have been given safely without the need for conditioning therapy, pre-medication, or cytokine support.

• The CaRe PC trial has recently dosed the first patient in the highest dose cohort and opened the phase II enrolment for subjects in the intermediate dose group. The dose of INKmune? in the intermediate and high dose cohorts is 3 and 5 times the dose of INKmune? in the first cohort. All eight clinical sites are now open and additional results from the trial will be released from the higher dose cohorts as they become available.

• Published landmark paper in Journal Immunotherapy of Cancer led by Mark Lowdell, PhD, INmune’s Chief Scientific Officer, titled, Proteomic and phenotypic characteristics of memory-like Natural Killer cells for cancer immunotherapy. The study demonstrates that memory-like natural killer (mlNK) cells, generated by either cytokine or INKmune^TM 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.

• Announced new formulation of INKmune? that supports highest trial dose with single bag administration and expansion of bioreactor capacity in preparation of scalable manufacturing. An IND amendment with the improved formulation has been submitted to the FDA that also includes additional validation data supporting an alternative critical reagent used in INKmune? manufacturing, improving supply chain redundancy.
  

Corporate:

• Executed securities purchase agreements with new and existing institutional investors and certain directors and officers and employees of the Company for gross proceeds of approximately $13.0 million.

• Added to the broad-market Russell 3000? Index at the conclusion of the 2024 Russell US Indexes annual reconstitution, effective as of Monday, July 1^st, 2024.

• Received a $2.5 million research and development rebate from Australia in July.
  

Upcoming Events and Milestones:

• Top-line data from the Phase 2 Alzheimer’s trial is expected in the second quarter of 2025.

• Initiate a Phase II trial of XPro? in patients with Treatment-Resistant Depression 2H 2024.

• Expect to complete enrollment in the Phase I portion of INKmune? in metastatic castration-resistant prostate cancer trial by year-end. The Phase II portion is expected to complete enrollment in Q2, 2025, however we expect to provide periodic updates on the immunologic and therapeutic response to INKmune? as data becomes available.
  

Financial Results for the Third Quarter Ended September 30, 2024:

• Net loss attributable to common stockholders for the quarter ended September 30, 2024 was approximately $12.1 million, compared to approximately $8.6 million during the quarter ended September 30, 2023.

• Research and development expenses totaled approximately $10.1 million for the quarter ended September 30, 2024, compared to approximately $6.0 million during the quarter ended September 30, 2023.

• General and administrative expenses were approximately $2.2 million for the quarter ended September 30, 2024, compared to approximately $2.6 million during the quarter ended September 30, 2023.

• As of September 30, 2024, the Company had cash and cash equivalents of approximately $33.6 million.

• As of October 31, 2024, the Company had approximately 22.2 million common shares outstanding.

About XPro?

XPro? is a next-generation inhibitor of tumor necrosis factor (TNF) that is currently in clinical trial and acts differently than currently available TNF inhibitors in that it neutralizes soluble TNF (sTNF), without affecting trans-membrane TNF (tmTNF) or TNF receptors. XPro? could have potential substantial beneficial effects in patients with neurologic disease by decreasing neuroinflammation. For more information about the importance of targeting neuroinflammation in the brain to improve cognitive function and restore neuronal communication visit this section of the INmune Bio’s website.

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?), 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.
