This expanded strategic collaboration secures the long-term, reliable supply of high-quality umbilical cord tissue from their world-class cord blood bank to fuel our CORDStrom™ platform. Hosted KOL led webinar focused on the latest results from the MissionEB Phase III clinical trial highlighting the systemic disease-modifying capabilities of CORDStrom™ in patients with RDEB. Announced the publishing of an overview of future applications and research areas for mesenchymal stromal cell (MSC) therapies in the peer-reviewed journal Cytotherapy. DN-TNF Platform: XPro™: Reported new Phase 2 imaging data at the 18th Clinical Trials on Alzheimer's Disease conference (CTAD), in San Diego, CA. Additional brain imaging analyses are ongoing and expected to be reported in the near future. Announced FDA alignment to advance to an adaptive Phase 2b/3 registrational pathway with XPro™ in early Alzheimer's Disease. Hosted expert-led webinar on XPro™ registrational study strategy for early Alzheimer's Disease, with the discussion focused on results of the Phase 2 MINDFuL trial and alignment with the FDA following the End-of-Phase 2 meeting. INmune’s MINDFuL trial was featured in a plenary presentation at the AD/PD 2026 conference as a successful example of how aligning patient selection with mechanism of action identifies the patients most likely to respond.

About CORDStrom™ CORDStrom™ is a patent-pending cell medicine comprising aseptic, allogeneic, pooled human umbilical cord-derived mesenchymal stromal cells (hucMSCs) in suspension for injection or infusion. The CORDStrom™ platform leverages, among other things, proprietary screening, pooling and expansion techniques to create off-the-shelf, allogeneic, pooled hucMSCs as medicines to treat complex inflammatory and autoimmune 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 affordably and with repeatable specification. Pooling allows tuning of different CORDStrom products with different effector functions dependent upon selected donor characteristics. While the first generation CORDStrom™ product is agnostic to disease indication, the platform enables creation of indication-specific products, which can be tuned for optimization of anti-inflammatory, immunomodulatory, wound healing, and other characteristics. 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 our website at www.inmunebio.com. 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 three product platforms: (1) CORDStrom™, a proprietary pooled, allogeneic, human umbilical cord-derived mesenchymal Stromal/Stem cell (hucMSCs) platform that recently completed a blinded randomized trial in recessive dystrophic epidermolysis bullosa; (2) XPro™, a Dominant-Negative Tumor Necrosis Factor (DN-TNF) product platform designed to selectively neutralize soluble TNF, a key driver of inflammation and innate immune dysfunction; and (3) INKmune®, a cell-based medicine designed to prime a patient’s natural killer cells to eliminate minimal residual disease in patients with cancer.
