INmune Bio Advances Ebstrocel™ Toward Potential UK Approval in Mid-2027
Boca Raton, Florida, October 21st, 2026, FinanceWire
- Final pre-MAA package submitted to MHRA on October 20, 2026
- Full MAA submission targeted for early February 2027, under a revised strategy that could bring potential UK approval forward by approximately six weeks
- US BLA expected to be submitted in Q2, 2027
INmune Bio Inc. (NASDAQ: INMB) (the “Company”), a late-stage biotechnology company focused on inflammation and immunology, today announced that it has submitted its final pre-Marketing Authorisation Application (pre-MAA) package to the UK Medicines and Healthcare products Regulatory Agency (MHRA) for Ebstrocel™ (CORDStrom™), its investigational cell therapy for recessive dystrophic epidermolysis bullosa (RDEB). The company has revised prior guidance to indicate that faster-than-expected manufacturing progress supports a full MAA submission in early February 2027, with potential UK approval in mid-2027, subject to MHRA review.
Following MHRA feedback on the final pre-MAA package, INmune Bio plans to finalize and submit a complete application in February, 2027, replacing the sequential rolling submission previously planned to begin in late 2026. Based on progress in chemistry, manufacturing and controls (CMC) and discussions with regulatory advisors, the Company believes this approach could accelerate potential UK approval by approximately six weeks from prior guidance.
The Company anticipates an MHRA response within three to six months after submission, subject to application validation, agency review and any requests for additional information. Submission of the complete package is intended to support assessment of the clinical, manufacturing and quality data together.
“This is a remarkable achievement by the whole CMC team and our external regulatory advisors allowing us to accelerate the potential approval for Ebstrocel for children with RDEB,” said Mark Lowdell, Chief Scientific Officer of INmune Bio. “Our progress allows us to bring forward the anticipated timeline to commercial supply, subject to approval, for children and families waiting for treatment.”
In parallel, INmune Bio has engaged U.S. regulatory advisors with rare disease expertise to prepare and submit a Type B meeting request to the U.S. Food and Drug Administration (FDA). Subject to feedback from that meeting, the Company plans to submit a Biologics License Application (BLA) in the second quarter of 2027, seeking traditional or accelerated approval, as appropriate.
“Based on positive feedback from our regulatory consultants in the U.S, we are prioritizing our FDA application ahead of an EMA submission, building on Ebstrocel’s U.S. Orphan Drug and Rare Pediatric Disease designations,” said David Moss, Chief Executive Officer of INmune Bio. “With potential UK and U.S. approvals in 2027, we are approaching a pivotal year. Approval in either or both markets would mark a major milestone for INmune Bio and bring Ebstrocel closer to patients and families living with RDEB.”

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:
- 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 in 2026 and EU EMA in 2027, alongside a planned U.S. Biologics License Application (BLA) submission.
- XPro1595™: A Dominant-Negative Tumor Necrosis Factor (DN-TNF) platform designed to selectively neutralize soluble TNF (sTNF) and reduce 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.
