Company Expresses Support for MHRA Draft Rare Disease Therapies Regulatory Framework BOCA RATON, Fla, July 20, 2026 <a href="https://www.globenewswire.com" target="_blank">(GLOBE NEWSWIRE)</a> -- INmune Bio Inc. (NASDAQ: INMB) (the “Company”), a late-stage biotechnology company focused on inflammation and immunology, today announced a significant manufacturing milestone for its CORDStrom™ platform. The Company has successfully processed its first commercial-ready umbilical cord tissue at the Cell and Gene Therapy Catapult (CGT Catapult) Manufacturing Innovation Centre in Stevenage, UK, under its commercial agreement with Anthony Nolan Cord Blood Bank. This achievement marks the successful transfer of the mesenchymal stromal cell (MSC) isolation stage for the manufacture of master cell banks (MCBs) into INmune Bio’s commercial manufacturing facility. The process is now commercial-ready to MHRA, EMA and FDA standards, including maternal blood samples infectious disease testing in US-CLIA-accredited laboratories. The successful technology transfer positions the Company to generate its first US tested master cell banks for Ebstrocel™, the RDEB-specific investigational product derived from the CORDStrom™ platform, in support of its planned Phase 3 confirmation clinical trial and future commercial supply. “Completing this manufacturing transfer is one of the most important operational milestones for the CORDStrom platform. We now have the manufacturing infrastructure required to generate master cell banks that support our planned Phase 3 program and future commercial production using a process designed to satisfy both UK and U.S. regulatory expectations. I am hugely proud of the team for getting to this milestone so quickly,” said Professor Mark W. Lowdell, PhD, FRCPath, FRSB, Chief Scientific Officer of INmune Bio.  “This important milestone reflects the strength of collaboration between Anthony Nolan, the Cell and Gene Therapy Catapult, and INmune Bio, and marks another critical step towards commercial delivery of Ebstrocel™,” said Dr. Ben Weil, MBA, EngD, Head of UK Operations at INmune Bio. “Everyone involved in the CORDStrom™ platform understands the urgency and criticality of developing potentially life-changing medicines to children living with RDEB and other rare diseases. Building a reliable, scalable, and commercial ready manufacturing platform is only possible through the commitment and expertise of all our suppliers and service partners.” With commercial manufacturing established, pediatric strategy approved, regulatory alignment completed and the MAA preparation underway, INmune Bio believes Ebstrocel™ has entered the final stage of development before planned commercialization in the United Kingdom. Alignment with MHRA Draft Rare Disease Therapies Regulatory Framework INmune Bio’s approach to developing Ebstrocel™ for recessive dystrophic epidermolysis bullosa (RDEB), an ultra-rare disease, is directly aligned with the principles recently outlined in the UK Medicines and Healthcare products Regulatory Agency (MHRA) draft rare disease therapies regulatory framework. The Company believes the principles proposed within the draft framework validate the regulatory strategy it has already established with the MHRA for Ebstrocel™. Specifically, the framework emphasizes flexible evidence generation, advanced statistical methodologies, patient-centered outcomes and lifecycle evidence development, principles reflected in the Company's recent written MHRA guidance supporting its planned Conditional Marketing Authorization application. "Commercial manufacturing is often one of the largest execution risks facing cell therapy companies. Today's milestone demonstrates that we have successfully transitioned from clinical manufacturing toward a scalable commercial process that supports our planned regulatory filings and long-term commercialization strategy. Combined with our recent regulatory alignment from the MHRA and the evolving UK rare disease framework, we believe CORDStrom is exceptionally well positioned for the next stage of development," said David Moss, CEO and co-founder of INmune Bio.

INmune Bio Inc. is a publicly traded (NASDAQ: INMB), late-stage biotechnology company focused on developing treatments that target the innate immune system to fight disease. Moving beyond early-stage exploration, the Company’s clinical-development strategy centers on advanced precision medicine, matching drug mechanisms directly to patient biology to optimize clinical outcomes. INmune Bio is actively advancing two late-stage product platforms toward registrational milestones: <ul><li style="margin-top:0in; margin-bottom:0in;">CORDStrom™: A proprietary, pooled, allogeneic, human umbilical cord-derived mesenchymal stromal cell platform engineered to address the historical clinical challenges of donor variability and manufacturing inconsistency. Following successful clinical readouts in RDEB, the platform is transitioning to regulatory filing phases, with an MAA planned for the UK MHRA and EU EMA in 2026, alongside a planned U.S. Biologics License Application (BLA) submission.</li></ul> <ul><li style="margin-top:0in; margin-bottom:0in;">XPro1595™: A Dominant-Negative Tumor Necrosis Factor (DN-TNF) platform that selectively neutralizes soluble TNF (sTNF) to eliminate neuroinflammation without compromising protective immune function. Backed by recently granted FDA Fast Track designation and successful regulatory alignment from an End-of-Phase 2 meeting, XPro1595™ is positioned for an integrated Phase 2b/3 seamless adaptive registrational program in neuroinflammation-enriched early Alzheimer’s disease.</li></ul> To learn more about INmune Bio’s pipeline and its approach to harnessing the innate immune system, please visit <a href="https://www.globenewswire.com/Tracker?data=DpTx-8hByotVkzgXuVMYw6Ahe86fMPeVmwdDVBlmirJkRT03R7moHlPq6UtXHB6FTge-QtdV23hVdznZPkhOUSQkN8ckpLeJ96Mlv7YXcEsekMYsGEZQRFhSyP_jkMCPUJkySa68EKzK0G_5GrX7Qo6XZyEfzuAaj1WEDo5XeXAEII-y4AFhDnR5R_xqn1fXI0JByhQ9Y2iEGLJrbsu2NmNLdGVAw68j0vRUlJtYtN9srJxTQNBQXD_AT_F8WdUV2tPcuBkrdeBAlQp6ncBMbQ==" rel="nofollow" target="_blank" title="www.inmunebio.com">www.inmunebio.com</a>.
