Boca Raton, Florida, US, April 16, 2025 (GLOBE NEWSWIRE) -- INmune Bio Inc. (NASDAQ: INMB), a clinical-stage biotechnology company targeting inflammation and immunology through the innate immune system, today announced a major intellectual property milestone with respect to its next-generation mesenchymal stromal cell (MSC) product, CORDStrom™.

The United States Patent and Trademark Office (USPTO), acting as the International Search Authority, has issued a favorable written opinion on all claims in INmune Bio’s international patent application PCT/US25/17028, titled “THERAPEUTIC COMPOSITIONS COMPRISING POOLED, CULTURE-EXPANDED HUMAN UMBILICAL CORD DERIVED MESENCHYMAL STROMAL CELLS.” The written opinion, received April 8, 2025, confirms that all claims possess novelty, inventive step, and industrial applicability – key requirements for patentability under international standards.

The CORDStrom™ platform represents an important advance in cell therapy. Unlike traditional MSC products, CORDStrom™ comprises pooled, culture-expanded human umbilical cord-derived MSCs (hucMSCs) designed for infusion or injection, potentially offering scalable, tunable, and consistent therapeutic performance across a wide range of inflammatory and degenerative diseases.

“We are encouraged with the examination results and the examiner’s favorable opinion of patentability concerning all submitted claims,” said Joshua Schoonover, General Counsel of INmune Bio. “CORDStrom is a first-in-class, pooled hucMSC medicine that offers batch-to-batch consistency and tunability across multiple disease indications. This patent application, once granted, will form the basis of IP exclusivity for our CORDStrom product platform through at least 2045, subject to patent term extension or adjustments.”

INmune Bio plans to accelerate prosecution of the U.S. national application via the Patent Prosecution Highway (PPH), a fast-track examination program that enables efficient and expedited review based on favorable rulings from international patent offices.

The favorable patent news follows promising data from a recent randomized Phase 2 trial, where CORDStrom™ demonstrated reductions in pain and itch, with early signals of improved skin integrity and disease activity. The company views this development as a pivotal step toward unlocking the full therapeutic and commercial potential of its MSC platform.

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 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. DN-TNF product candidates are in clinical trials to determine if they can treat 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 and is currently in phase II trial in metastatic castration-resistance prostate cancer in the US. The third program, CORDStrom™, is a proprietary pooled, allogeneic, human umbilical cord-derived mesenchymal Stromal cell (hucMSCs) platform that recently completed a blinded randomized trial in recessive dystrophic epidermolysis bullosa in the UK.
