Current report

Our objective is to develop and commercialize our product candidates to treat diseases where the innate immune system is dysfunctional causing or contributing to the patient’s disease. Innate immune dysfunction can occur for a variety of reasons including genetics, lifestyle, and other factors. However, age plays a significant role in the development of immune dysfunction. Innate immune dysfunction can be seen in cancer where Natural Killer (“NK”) cells are impaired and facilitate a tumor’s evasion of the immune system and subsequent disease progression. Chronic inflammation is implicated in neurologic and metabolic diseases where it impairs the innate immune system. Our primary focus continues to be treatment of cancer with INKmune and treatment of Alzheimer’s Disease (“AD”) and Treatment Resistant Depression (“TRD”) with XPro1595. We have added CORDStrom, a pooled, human umbilical cord mesenchymal stem cell product to treat recessive dystrophic epidermolysis bullosa (RDEB), a pediatric orphan disease caused by mutations in the COL7A1 gene that results in a debilitating disease of skin blistering, dysphagia and failure to thrive with chronic wound problems that often results in fatal squamous cell carcinoma.

Current report

XPro1595 (“XPro”), targets Alzheimer’s Disease and TRD. XPro for AD has completed Phase I trials and a Phase II trial has completed enrollment of patients at clinical sites in the United Kingdom, EU, Australia and Canada. Patients are currently being treated with XPro for Early AD as part of that clinical trial. TRD is being prepared for Phase II trials. We expect to start a pivotal global registration trial in patients with AD after the results of the Phase II trial have been analyzed. The INKmune program is in an open label Phase II trial in metastatic castrate resistant prostate cancer (mCRPC). CORDStrom for the treatment of children with RDEB has completed a pivotal blinded randomized cross-over trial. The data will be submitted for a marketing authorization by filing a Biologics License Application (BLA) with the FDA in the US which is anticipated in late 2025 or early 2026. Afterwards, the company intends to file a Marketing Authorization Application (MAA) in the United Kingdom and EU.

Current report

CORDStrom, developed by INmune Bio circa 2020, represents a breakthrough in mesenchymal stem cell technology. The CORDStrom platform leverages, among other things, proprietary screening, pooling and expansion techniques to create off-the-shelf, allogeneic, pooled human umbilical cord -derived mesenchymal stromal cells (HucMSCs) as medicines to treat complex inflammatory diseases. CORDStrom products are designed to provide high-quality, off-the-shelf, batch-to-batch consistent, scalable, cGMP manufactured, potent cellular medicines that can be produced at low cost and with repeatable specification independent of donor characteristics. Initially developed at the INKmune manufacturing facilities utilizing United Kingdom academic grant funding, CORDStrom is a product platform that shows promise as a therapy for RDEB and many other debilitating conditions. While the first generation CORDStrom product is agnostic to indication, the platform enables creation of indication-specific products, which can be tuned for optimization of anti-inflammatory, immunomodulatory, wound healing, and other characteristics.

Current report

The CORDStrom product platform shares many similarities, including starting materials, equipment, and procedures, with the Company’s INKmune oncology product, enabling the Company to leverage economies of scale, experienced staff, and other resources to strategically manufacture both products in a rotational campaign with resource and environmental efficiencies.

Current report

Children with Recessive Dystrophic Epidermolysis Bullosa (RDEB) have skin that is damaged by even the smallest amount of friction which causes severe blistering, deep wounds, and scars. It is caused by a fault in a gene that makes collagen, a protein that holds the skin layers together. There are limited options available for treatment, none that adequately meet the needs of patients, and the condition gets worse over time with most children reliant on a wheelchair as they move into their teenage years. Many of those with an RDEB diagnosis will also go on to develop aggressive life-threatening skin cancer in adulthood caused by the accumulated damage to their skin. The Company estimates roughly 2,000 people suffer from RDEB in the US, United Kingdom and EU representing a large unmet opportunity to potentially provide routine clinical care to these children.

Current report

Since 2020, the Company has supplied CORDStrom HucMSCs as an investigational medical product to the Great Ormond Street Hospital (GOSH), London, in connection with the MissionEB study, which was primarily funded by a grant from the National Institute for Health and Care Research (NIHR) in the United Kingdom. INmune Bio was compensated for CORDStrom used in the trial and was not a sponsor of the Mission EB study. Investigators recently concluded a double blinded, placebo-controlled arm of the study, which evaluated the safety and efficacy of CORDStrom in 30 pediatric patients (less than 16 years old) in the United Kingdom with intermediate and severe RDEB using a novel cross-over clinical trial design. Patients were randomized to CORDStrom or placebo arms and received 2, intravenous infusions two weeks apart and then followed for 9 months. Each child then crossed over to the other arm and received two doses of placebo or CORDStrom two weeks apart with a further 9-month follow-up.

Current report

All patients were treated as day-cases and no CORDStrom related serious adverse events were reported through the study. Top-line results showed the treatment was easily administered, well tolerated and there were beneficial effects across all types of patients receiving CORDStrom with respect to Itch Man Scale, iscorEB clinician score and iscorEB skin involvement. Most notably, CORDStrom significantly reduced itch scores as measured by the Itch Man Scale. In patients with the most severe disease activity, CORDStrom reduced itch at 3 months and led to a sustained reduction of over 27% at 6 months. These results demonstrate a clinically meaningful reduction in itch severity sustained over time. Intermediate group patients showed a broader range of improvements, including reduced skin involvement and less pain as well as large reduction in itch. The younger patients (less than 10 years old) showed improvements in skin score, indicating better skin integrity and reduced disease activity. Interviews with patients and caregivers on completing follow up strongly support the clinical benefits of the therapy; both caregivers and patients were able to correctly identify which treatment had been CORDStrom and which had been placebo. Those who completed the study are asking to continue on therapy, which the Company intends to pursue as an open-label study.

Current report

The Mission EB data form the basis of a license that was entered into between INmune Bio and GOSH, whereby the Company gains exclusive access to the clinical study data for commercial uses in exchange for payment of an initiation milestone of £250,000 (approximately $0.3 million at February 6, 2025) and a single development milestone of approximately £6 million (approximately $7.5 million at February 6, 2025) due on receipt of first marketing authorization from the FDA, EMA, or MHRA, and an ongoing commitment to supply CORDStrom to patients enrolled in an open label arm of the Mission EB trial, subject to certain limitations.

Current report

After reviewing results of the Mission EB study, the Company initiated a Type C meeting with the FDA to obtain CMC and regulatory feedback and submitted information, data and requests for Rare Pediatric Disease and Orphan Drug Designations (RPDD/ODD).

Current report

The FDA granted RPDD to the Company’s CORDStrom product on December 13, 2024, ahead of the sunset period under Section 529(b)(5) of the Federal Food, Drug, and Cosmetic Act. As such, CORDStrom remains eligible to receive a Priority Review Voucher (PRV) if approved by the FDA on or prior to September 30, 2026. If granted, a PRV can be redeemed to receive priority review for a different product. Alternatively, a PRV may be transferred or sold to another sponsor.

Current report

The FDA granted ODD to the Company’s CORDStrom product on January 6, 2025. Benefits of ODD include certain tax credits and eligibility for select grants, waiver of FDA user fees, including the BLA application fees, access to frequent meetings with the FDA for efficient drug development, and eligibility for seven (7) years of market exclusivity post approval.

Current report

The company plans to prepare for and hold a pre-BLA meeting to discuss particulars of its planned BLA submission, with intent to submit a BLA this year seeking approval of CORDStrom for treatment of RDEB. Concurrently, the company will also seek to submit MAAs to the EU and United Kingdom in 2026.

Current report

The Company generated other income of $553,000 in 2024 compared to other expense of $267,000 in 2023. The change is due to the Company incurring $1.5 million lower interest expense in 2024 as a result of the Company paying off its debt in full in 2024, partially offset by earning $0.7 million lower interest income from money market investments in 2024 as a result of lower amounts invested in money markets investments in 2024.

Previous report

We are a clinical-stage immunology company focused on developing drugs that may reprogram the patient’s innate immune system to treat disease. We believe this may be done by targeting cells of the innate immune system that cause acute and chronic inflammation and are involved in immune dysfunction associated with chronic diseases such as cancer and neurodegenerative diseases. The Company’s drugs are in clinical trials and have not been approved by a regulatory authority. The Company has two therapeutic platforms – a dominant-negative TNF platform (“DN-TNF”, “XPro™”, “XPro1595™” or “pegipanermin”) and a Natural Killer (“NK”, or “INKmune™”) platform. The DN-TNF platform neutralizes soluble TNF (“sTNF”) without affecting trans-membrane TNF (“tmTNF”) or TNF receptors -TNFR1 and TNFR2. This unique biologic mechanism differentiates the DN-TNF drugs from currently approved non-selective TNF inhibitors that inhibit both sTNF and tmTNF. Protecting the function of tmTNF and TNF receptors while neutralizing the function of sTNF is a potent anti-inflammatory strategy that does not cause immunosuppression or demyelination which occur in the currently approved non-selective TNF inhibitors. Currently approved non-selective TNF inhibitors treat autoimmune disease, but are contraindicated in patients with infection, cancer and neurologic diseases because they increase the risk of infection, cancer and demyelinating neurologic diseases, respectively; these safety problems are due to off-target effects on inhibiting tmTNF. The NK platform targets the dysfunctional natural killer cells in patients with cancer. NK cells are part of the normal immunologic response to cancer with important roles in immunosurveillance to prevent cancer and in preventing relapse by eliminating residual disease. Residual disease is the cancer left behind after therapy is finished. Residual disease can grow to cause relapse. The mechanism by which INKmune improves the ability of the patient’s NK cells to kill their cancer is complex. The NK cells of cancer patients lose the ability to bind and kill cancer cells. A measure of NK cell binding to cancer cells is avidity. The higher the avidity, the greater the bond between the NK cell to cancer cell and thus the greater NK killing of cancer cells. INKmune increases NK avidity and further improves mitochondrial function and upregulates nutrient receptors. These metabolic changes may help the INKmune primed NK cell to function in the hostile tumor microenvironment and persist much longer. These mechanisms improve the ability of INKmune primed NK cells to overcome the immune evasion of the patient’s cancer cells. We believe INKmune is best used to eliminate residual disease after the patient has completed other cancer therapies. Both the DN-TNF platform and the INKmune platform can be used to treat multiple diseases. The DN-TNF platform will be used as an immunotherapy for the treatment of cancer and neurodegenerative disease. INKmune is being d…

As a company with less than $1.235 billion in revenue during our last fiscal year, we qualify as an “emerging growth company” under the JOBS Act. As an emerging growth company, we may take advantage of specified reduced disclosure and other requirements that are otherwise applicable generally to public companies. These provisions include:

Previous report

We have elected to take advantage of the above-referenced exemptions and we may take advantage of these exemptions for up to five years or such earlier time that we are no longer an emerging growth company. We would cease to be an emerging growth company if we have more than $1.235 billion in annual revenues, we have more than $700 million in market value of our stock held by non-affiliates, or we issue more than $1 billion of non-convertible debt over a three-year period. We may choose to take advantage of some but not all of these reduced burdens.

Critical Accounting Policies and Significant Judgments and Estimates

Previous report

R&D expenses consist primarily of costs related to clinical studies and outside services, personnel expenses, and other R&D expenses. Clinical studies and outside services costs relate primarily to services performed by clinical research organizations and related clinical or development manufacturing costs, materials and supplies, filing fees, regulatory support, and other third-party fees. Personnel expenses relate primarily to salaries, benefits and share-based compensation. R&D expenditures are charged to operations as incurred.

Previous report

We recognize R&D tax credits receivable from the Australian government for spending on R&D as a reduction of R&D expenses.

Previous report

Other expense, net decreased to $0.3 million during the year ending December 31, 2023, compared to $1.3 million during the year ending December 31, 2022. The decrease in other expense is due to the Company earning higher interest income from money market investments in 2023 ($1.3 million higher) partially offset by higher interest expense on the Company’s debt in 2023 ($0.3 million higher).

Previous report

During July 2023, the Company sold 75,697 shares of its common stock at an average price of $10.56 per share under the ATM program. The aggregate net proceeds were approximately $775,000 after offering expenses.

Previous report

On June 10, 2021, we entered into a Loan and Security Agreement with SVB and an affiliate of SVB, providing for a $15.0 million term loan. The Term Loan provides for an annual interest rate equal to the greater of (i) the prime rate then in effect as reported in The Wall Street Journal plus 4.50% and (ii) 7.75% and also includes a final payment fee equal to 6.5% of the original principal amount borrowed payable on the earlier of the repayment of the loan in full and the maturity date. The Term loan is payable in 2024.

Previous report

During the year ended December 31, 2023, the Company repaid $5 million of its debt.

Previous report

During the year ended December 31, 2022, the Company sold 82,900 shares of its common stock to certain officers and directors for approximately $0.7 million.
Reworded paragraphs (16)

Previous wording

We believe our DN-TNF platform can be used as a CNS (“central nervous system”) therapy to target glial activation to prevent progression of Alzheimer’s disease (“AD”); to target neuroinflammation in treatment resistant depression (“TRD”); as a drug to prevent muscle degeneration, prevent fibrosis and promote muscle regeneration in Duchene muscular dystrophy (“DMD”); and as a cancer therapy to reduce resistance in immunotherapy. The primary focus of the company’s development efforts for XPro is AD. The next indication to be developed with XPro will be TRD. Treatment of DMD and cancer will occur when partners for the programs are found. The drug is named differently for the oncology and CNS indications; INB03™ or XPro, respectively, but it is the same drug product. For DMD, the company is exploring DN-TNF compounds that is optimized for the treatment of DMD. This novel compound has the same mechanism of action but has novel IP protection. In each case, we believe neutralizing sTNF is a cornerstone to the treatment of these diseases. As an immunotherapy for cancer, we are using INB03 to neutralize sTNF produced by HER2+ trastuzumab resistant breast cancers to reverse resistance to targeted therapy. sTNF produced by the tumor causes an up-regulation of MUC4 express causing steric hindrance of trastuzumab binding to the HER receptor on HER2+ breast cancer cells. Without binding, trastuzumab based therapies are not effective. Neutralizing sTNF reverses MUC4 expression converting a trastuzumab resistant breast cancer cell into a trastuzumab sensitive breast cancer cell. In addition, INB03 may change the immunobiology of the tumor microenvironment by decreasing the number of immunosuppressive myeloid cells, both myeloid derived suppressor cells and tumor active macrophages, and increasing the number of cytotoxic lymphocytes and phagocytic macrophages in the TME. The Company has completed an open label dose escalation trial in cancer patients with metastatic solid tumors that have failed multiple lines of therapy. The pre-clinical data in MUC4+ expressing tumors and the clinical trial informs the design of a future Phase II trial by demonstrating that INB03 was safe and well tolerated, defined the dose of INB03 to carry into Phase II trials, and demonstrated a pharmacodynamic end-point. The company does not plan to commence a Phase II trial in patients with advanced MUC4+ expressing cancer until a partner can be found.

Current wording

We believe our DN-TNF platform can be used as a CNS (“central nervous system”) therapy to target glial activation to prevent progression of Alzheimer’s disease (“AD”); to target neuroinflammation in treatment resistant depression (“TRD”). The primary focus of the company’s development efforts for XPro is AD. The next indication to be developed with XPro will be TRD. In each case, we believe neutralizing sTNF is a cornerstone to the treatment of these diseases.

Previous wording

Likewise, we believe the DN-TNF platform can be used to treat selected neurodegenerative diseases by modifying the brain microenvironment (“BME”). The Company believes the core pathology of cognitive decline is a combination of neurodegeneration and synaptic dysfunction. Neurodegeneration is nerve cell death that may include demyelination. Synaptic dysfunction means the connections between nerve cells stop working efficiently and may decrease in number. The combination of neurodegeneration and synaptic dysfunction causes cognitive decline and behavioral changes associated with Alzheimer’s disease (“AD”). XPro completed a Phase I trial treating patients with Alzheimer’s disease that was partially funded by a Part-the-Clouds Award from the Alzheimer’s Association. We believe XPro targets activated microglia and astrocytes of the brain that produce sTNF that promotes nerve cell loss, synaptic dysfunction and prevents myelin repair - key elements in the development of dementia. In animal models, elimination of sTNF prevents nerve cell dysfunction, reverses synaptic pruning and promotes myelin repair. The Phase I trial in patients with biomarkers of inflammation with AD has been completed. The open label, dose escalation trial was designed to demonstrate that XPro can safely decrease neuroinflammation in patients with ADi. ADi is the term used to delineate patients with AD with biomarkers of inflammation. The endpoints of the trial were measures of neuroinflammation and neurodegeneration in blood and cerebral spinal fluid by measuring changes in inflammatory cytokine levels in the CNS and using MRI-DTI to measure brain microstructural changes. XPro, at the 1mg/kg/week dose, decreased inflammatory cytokines in the CSF in the brain demonstrating that XPro can decrease neuroinflammation in patients with AD. We also studied downstream benefits of decreasing neuroinflammation by measuring changes in the CSF proteome and quantifying changes in novel white matter MRI biomarkers. XPro significantly decreases biomarkers of neurodegeneration as measured by changes in the CSF proteome including neurofilament light chain, phospho Tau 217 and VILIP-1; decreases of 84%, 46% and 91% respectively after 3 months of therapy. Three months of XPro therapy improved measures of synaptic function, as measured in the CSF proteome including a 222% increase in Contactin 2 and a 56% decrease neurogranin, changes that contribute to improved synaptic function.

Previous wording

The successful completion of the Phase I trial in AD has informed the design of a blinded randomized, placebo-controlled Phase II trial in patients with early ADi. Early ADi includes patients with AD and MCI who have at least one biomarker of inflammation (ADi and MCI 2 respectively). The early ADi trial is a blinded randomized trial to test if treatment of early AD patients with neuroinflammation with XPro will affect cognitive decline. The Phase II trial in early ADi has six important elements. Two hundred and one patients are being enrolled in a 2:1 ratio (XPro vs placebo). The patients will receive 1mg/kg/week as a subcutaneous injection for six months. An enrichment strategy identical to the successful strategy used in the Phase I trial will be used to ensure patients have neuroinflammation. Patients will need to have one or more enrichment criteria: elevated blood level of at least one of C-reactive protein, hemoglobin A1c, erythrocyte sedimentation and at least one allele of ApoE4. The primary end-point will be Early/mild Alzheimer’s Cognitive Composite (“EMACC”), a validated cognitive measure that is more sensitive than traditional end-points used in many studies of patients with early AD. The AD program is open in the United States, Australia, Canada, the United Kingdom, France, Germany, Spain, Czech Republic and Slovakia. All patients will be offered to stay on therapy for at least 12 months in an extension trial. Clinical and biomarker data will be collected during the extension trial.

Current wording

The AD program is open in Australia, Canada, the United Kingdom, France, Germany, Spain, Czech Republic and Slovakia.

Previous wording

There are at least 4 clinical milestones associated with the Phase II trial in AD. Enrollment of 201 patients in the Phase II AD trial should be complete by mid-year. Six months after the last patient is enrolled, top line cognition data with EMACC will be available. Secondary end-points which include blood biomarker, neuroimaging and additional neuropsychiatric end-points will be available after data base lock 2-3 months after top line data. Finally, several months after all the data are analyzed, the Company plans an end-of-phase II meeting with the FDA to finalize plans for the pivotal Phase III trial. The Company plans to apply for an accelerated pathway during 2024. XPro for treatment of AD may be eligible for one or both accelerated approval pathways. The Company plans to submit of Fast Track status in 2024. We expect to be eligible for Break Through status after completion of the Phase II in 2025.

Current wording

Full enrollment in the Phase II AD trial occurred in late 2024 with 208 patients enrolled. Topline data of EMACC is expected to be reported in June followed by secondary end-points which include blood biomarker, neuroimaging and additional neuropsychiatric end-points which should be available 2-3 months after top line data. Finally, several months after all the data are analyzed, the Company plans an end-of-phase II meeting with the FDA to finalize plans for the pivotal Phase III trial. XPro for treatment of AD may be eligible for one or both accelerated approval pathways. We expect to be eligible for Break Through status after completion of the Phase II in 2025.

Previous wording

Effective therapy for TRD is a large unmet need. Twenty percent of patients with a Major Depressive Disorder have TRD. Once third of TRD patients have peripheral biomarkers to inflammation (elevated CRP). This is a large patient population. The role of TNF and anti-TNF therapeutics was explored in a small open label clinical trial by Prof. Andrew Miller, MD of Emory University demonstrated the patients have elevated TNF levels and treatment with infliximab treated their depression (Miller, 2011). The Company received a $2.9M USD award from the National Institute of Mental Health (“NIMH”) to treat TRD with XPro. The blinded, randomized Phase II trial will use biomarkers of peripheral inflammation to select patients with TRD for enrollment. Patients will be treated for 6 weeks. Primary end-points include both clinical and neuroimaging measures. The final trial design is ongoing and discussions with the FDA are not complete. The Company received authorization to initiate a clinical trial in AD in the US during January 2024. The TRD trial is expected to start enrollment after the AD Phase II trial finishes patient enrollment.

Current wording

Effective therapy for TRD is a large unmet need. Twenty percent of patients with a Major Depressive Disorder have TRD. Once third of TRD patients have peripheral biomarkers to inflammation (elevated CRP). This is a large patient population. The role of TNF and anti-TNF therapeutics was explored in a small open label clinical trial by Prof. Andrew Miller, MD of Emory University demonstrated the patients have elevated TNF levels and treatment with infliximab treated their depression (Miller, 2011). The Company has a $2.0M USD award from the National Institute of Mental Health (“NIMH”) to treat TRD with XPro. The blinded, randomized Phase II trial will use biomarkers of peripheral inflammation to select patients with TRD for enrollment. Patients will be treated for 6 weeks. Primary end-points include both clinical and neuroimaging measures. The TRD trial is expected to start enrollment during 2025.

Previous wording

The Phase I/II trial using INKmune to treat patients with metastatic castrate resistant prostate cancer (mCPRC) is an open label trial. Biomarker data from the patients will be visible as patients are treated. The Company will report data from each cohort as it becomes available. In addition to clinical data, the Company will communicate when the Phase I portion of the trial has completely enrolled. This is expected in September 2024. Because of the modified Bayesian design, the Company estimates the trial will be completely enrolled 1H25 with top-line data available 6 months later. Topline data is divided into immunologic and tumor response variables. The most important immunologic response variable is related to memory like NK cell persistence. This is how long are the number of mlNK cells in patients blood compared to baseline. There are 3 important variables to tumor response: i) blood PSA changes; ii) change in PMSA scan and iii) change in circulating tumor DNA (ctDNA). Ideally, the levels of all three variables decrease with treatment. We do not expect this 6 month trial to provide survival data.

Previous wording

We continue to incur significant development and other expenses related to our ongoing operations. As a result, we are not and have never been profitable and have incurred losses in each period since our inception, resulting in substantial doubt in our ability to continue as a going concern. We reported a net loss of $30.0 million and $27.3 million for the years ended December 31, 2023 and 2022, respectively. As of December 31, 2023 and 2022, we had cash and cash equivalents of $35.8 million and $52.2 million, respectively. We expect to continue to incur significant losses for the foreseeable future, and we expect these losses to increase as we continue our research and development of, and seek regulatory approvals for, our product candidates. The size of our future net losses will depend, in part, on the rate of future growth of our expenses and our ability to generate revenues, if any.

Our recurring net losses and negative cash flows from operations raised substantial doubt regarding our ability to continue as a going concern within one year after the issuance of our consolidated financial statements for the year ended December 31, 2023. Until we can generate sufficient revenue from the commercialization of our product candidates, we expect to finance our operations through the public or private sale of equity, debt financings or other capital sources, such as government funding, collaborations, strategic alliances, divestment of non-core assets, or licensing arrangements with third parties. To date, the Company has relied on equity and debt financing to fund its operations.

The Company incurs significant research and development expenses in Australia and the United Kingdom. Fluctuations in the rate of exchange between the United States dollar and the pound sterling as well as the Australian dollar could adversely affect our financial results, including our expenses as well as assets and liabilities. We currently do not hedge foreign currencies but will continue to assess whether that strategy is appropriate. As of December 31, 2023, the cash balance held by our foreign subsidiaries with currencies other than the United States dollar was approximately $0.5 million.
