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 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 UK academic grant funding, CORDStrom™ is an MSC product platform that shows promise as a first systemic therapy for potentially treating RDEB and many other debilitating conditions. 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 this section of 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 three product platforms: 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. The second program, CORDStrom™, is 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. The third program, INKmune®, is designed to prime a patient’s natural killer cells to eliminate minimal residual disease in patients with cancer and is currently in a trial in metastatic castration-resistance prostate cancer.
