Pre-submission package is a process that facilitates early feedback from the United Kingdom (UK) Medicines and Healthcare Products Regulatory Agency (MHRA), designed to streamline the final approval process and reduce time to market

Boca Raton, FL, Feb. 10, 2026 (GLOBE NEWSWIRE) -- INmune Bio Inc. (NASDAQ:INMB) ("INmune" or the "Company"), a clinical-stage inflammation and immunology company, today announced a critical step toward the commercialization of CORDStrom™ for the treatment of recessive dystrophic epidermolysis bullosa (RDEB). The Company has formally submitted its pre-submission package for CORDStrom with the United Kingdom's Medicines and Healthcare Products Regulatory Agency (MHRA). This early engagement step is designed to solicit targeted scientific, regulatory, and procedural feedback, streamlining the full Marketing Authorization Application (MAA) process and potentially shortening time to market for what could become the first systemic therapy for this devastating "butterfly skin" disease.

CORDStrom is being developed as a disease-modifying treatment for recessive dystrophic epidermolysis bullosa (RDEB), a rare, debilitating genetic disorder affecting approximately 1 in 1 million births worldwide. Characterized by extreme skin fragility, chronic wounds, severe itch and pain, gastrointestinal/esophageal complications, and elevated skin cancer risk, RDEB has no approved systemic therapies. Current options are limited to topical wound treatments.

"Meeting the deadline for our pre-submission for CORDStrom marks a critical milestone, building upon the positive safety and efficacy data demonstrated in the MissionEB clinical trial and the successful transition into our commercial manufacturing facility in Stevenage, UK," said Professor Mark Lowdell, PhD, FRCPath FRSB, Co-Founder & CSO of INmune Bio. "The Mission EB trial demonstrated improvement in itch, pain, skin integrity and quality of life, with excellent tolerability and no treatment-related serious adverse events. We are committed to delivering the first systemic therapy for RDEB patients and families, starting in the UK, and look forward to feedback from the MHRA in the hope of accelerating the regulatory and commercial pathway to approval."

INmune Bio has completed three commercial pilot-scale manufacturing runs at the state-of-the-art CGT Catapult facility, each demonstrating consistent product characteristics that met predefined release criteria. These manufacturing results confirm readiness for commercial supply. The Company anticipates filing a full Marketing Authorization Application (MAA) with MHRA following receipt of pre-submission feedback, currently targeted for mid-summer 2026, with subsequent EU and U.S. regulatory submissions to follow in Q4, 2026, subject to regulatory alignment and manufacturing readiness.

While advancing the regulatory pathway in the UK, INmune Bio also stands to benefit from recent U.S. legislative progress regarding rare pediatric diseases. CORDStrom has already been granted both Orphan Drug Designation (ODD) and Rare Pediatric Disease (RPD) designation for the treatment of EB in the United States. These designations take on added significance following the February 3, 2026, passed legislation that reauthorizes the FDA's Rare Pediatric Disease Priority Review Voucher (PRV) program through September 30, 2029 (incorporated into the Consolidated Appropriations Act, 2026, via the Mikaela Naylon Give Kids a Chance Act). The program incentivizes development of therapies for rare pediatric diseases like RDEB by awarding a transferable priority review voucher upon approval.

"We welcome Congress's bipartisan action to extend the Rare Pediatric Disease PRV program," said CEO David Moss. "This reauthorization removes a major uncertainty and strengthens the incentive landscape for advancing innovative treatments for children with devastating rare conditions. With our planned BLA submission targeted for later this year, we are well-positioned to potentially benefit from this important incentive as we work to bring CORDStrom™ to RDEB patients who urgently need new options."

CORDStrom is potentially the first systemic treatment designed to address the severe unmet symptoms of RDEB patients. RDEB not only manifests as extreme fragility of the skin but also inflammation of internal linings of the mouth, gut and behind the eyes, leading to widespread pain, failure to thrive and multi-organ complications and even increasing the risk of skin cancer. RDEB affects nearly every organ system. Limited options are available for treatment, none of which address the systemic tissue damage.

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, independent of 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.
