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 March 31, 2024 and provides a business update.

Q1 2024 and Recent Corporate Highlights

DN-TNF Platform Highlights (XPro™):

  • The AD02 randomized, blinded program for patients with Early Alzheimer's Disease remains on schedule to reach its final enrollment target by mid-2024, with top-line data expected to be presented approximately six months after the last patient is enrolled. The trial is currently active in North America, UK, EU, and the Pacific Rim. The Company anticipates having its Phase II FDA meeting in the first half of 2025 before transitioning to the global Phase III trial in the latter portions of next year.
  • The Company successfully completed extended stability validation for XPro™ at continuous storage in solution at 2C-8C. The 24 and 30-month stability test samples passed all chemistry and potency assays allowing the Company to make a conservative claim of 24-month stability and positioning it to meet the dosing demands envisioned in the Phase III trial.
  • On April 30th, the Company issued a press release highlighting the progress of two patients from the Phase 1b AD trial in Australia who have continued to receive XPro™ treatment under an open-label program administered by their treating physician. The testimonials underscore XPro’s™ unique attributes that may prevent progression cognitive impairment versus existing treatments that appears to slow the pace of but do not stop the progression of cognitive dysfunction.
  • INB03 cancer platform – two posters were presented at the annual American Association of Cancer Research in San Diego on April 8, 2024. The posters extends ongoing research led by Roxana Schillaci, Ph.D., of Instituto de Biología y Medicina Experimental in Buenos Aries, Argentina on the importance of MUC4 expression in high-risk breast cancer subtypes is a predictor of progression and resistance to therapy. Tumors that express MUC4 have an unfavorable immunobiology of the tumor microenvironment (TME) and increased metastatic potential all driven by soluble TNF. Neutralization of soluble TNF with INB03 resulted in down-regulation of immune checkpoint proteins on T cells (PD1, TIGIT, LAG3 and CTLA4) and macrophages (CD47 and SIRPꭤ) in the TME. The data suggests testing for MUC4 before treatment will predict resistance to first-line therapy which may allow better treatment choices that may improve patient outcomes. 

INKmune™ Platform:

  • The first cohort in the Phase I/II open label trial of INKmune™ in metastatic castration-resistant prostate cancer (mCRPC) successfully completed the first dosing. Following review by the Safety Review Committee (SRC), approval was granted to proceed with the second dose level (cohort 2) and two patients have been enrolled.  The first patient of the middle dose cohort is expected to be treated this month.
  • Safety of INKmune remains on track. There have been nine administrations of INKmune in the mCRPC study given on an out-patient basis, with no significant adverse events. Combining the experience with INKmune from the MDS/AML and mCRPC trials, over 20 infusions of INKmune have been given safely without the need for conditioning therapy, pre-medication, or cytokine support. Patients receive three infusions of INKmune™ per dosing over two weeks and are monitored for four months for immunological and clinical responses. Three dose levels of INKmune™ are being tested in a modified Bayesian Phase I/II trial.


  • The Company successfully raised a combined $14.5 million of equity capital before placement agent fees and expenses in two separate transactions in late April. Of note, in the first $4.8 million offering, management, employees and members of the Board of Directors purchased over 20% of the offering. Excluding shares and warrants acquired by insiders, both offerings were priced at the market. The warrants terminate on the earlier of (1) the two (2) year anniversary of the initial exercise date of the warrant or (2) thirty (30) trading days following the reporting of top line data (EMACC) in the Phase 2 Alzheimer's program of XPro1595, (the “Termination Date”). Should the warrants be exercised for cash, the Company would receive additional funding.

Upcoming Events and Milestones:

  • Full enrollment in the Phase II XPro™ trial for treatment of neuroinflammation as a cause of Alzheimer’s Disease are expected mid-2024 followed by top-line data approximately six months from the last patient enrolled.
  • 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 the mCRPC trial by end of Q3 2024. The Phase II portion is expected to complete enrollment in Q2, 2025. Because the trial is open-label, we expect to provide periodic data updates on the immunologic and therapeutic response to INKmune in the participants of the CaRePC trial in mCPRC.

Financial Results for the First Quarter Ended March 31, 2024:

  • Net loss attributable to common stockholders for the quarter ended March 31, 2024 was approximately $11.0 million, compared to approximately $6.5 million during the quarter ended March 31, 2023.
  • Research and development expenses totaled approximately $8.7 million for the quarter ended March 31, 2024, compared to approximately $4.1 million during the quarter ended March 31, 2023.
  • General and administrative expenses were approximately $2.3 million for the quarter ended March 31, 2024, compared to approximately $2.3 million during the quarter ended March 31, 2023.
  • As of March 31, 2024, the Company had cash and cash equivalents of approximately $26.0 million. Subsequent to the end of the quarter, the Company raised gross proceeds of approximately $16.6 million from the sale of common stock and warrants.
  • As of May 9, 2024, the Company had approximately 19.8 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™), 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.
