INmune Bio Inc. Announces Second Quarter 2026 Results and Highlights Regulatory, Manufacturing and Clinical Progress

Company to Host Conference Call Today, August 6th, at 4:30pm ET

BOCA RATON, Fla., Aug. 06, 2026 (GLOBE NEWSWIRE) -- INmune Bio Inc. (NASDAQ: INMB) (the “Company”), a late-stage biotechnology company focused on inflammation and immunology, today announced its financial results for the quarter ended June 30, 2026 and provided a business update.

“The second quarter and subsequent weeks were defined by execution across both of our late-stage platforms,” said David Moss, Chief Executive Officer of INmune Bio. “For Ebstrocel™, we secured MHRA alignment, PIP approval and commercial-ready manufacturing, materially reducing regulatory and operational risk ahead of our planned UK MAA submission. For XPro™, FDA Fast Track designation and statistically significant MRI findings strengthened the clinical and regulatory foundation for a registrational Phase 2b/3 program in early Alzheimer’s disease that we believe establishes XPro™ as a first-in-class, late-stage neuroimmunology program in CNS disease. Looking ahead, our core priority is clear: driving Ebstrocel efficiently through regulatory filing and approval to bring this critical therapy to patients in need while delivering long-term value for our shareholders.”

Second Quarter and Recent Corporate Highlights  

CORDStrom™ Platform (Ebstrocel for RDEB):

Completed a key commercial manufacturing milestone by successfully processing the first commercial-ready umbilical cord tissues at the Cell and Gene Therapy Catapult Manufacturing Innovation Centre in Stevenage, UK. The transferred process is designed to meet MHRA, EMA and FDA standards and supports planned Phase 3 confirmatory development, global regulatory submissions and future commercial supply.

Received formal MHRA written alignment across the CMC, non-clinical and clinical elements of the planned UK MAA, providing a clear regulatory path toward a Conditional Marketing Authorization application for Ebstrocel™ in RDEB.

Obtained MHRA approval of the Ebstrocel™ Pediatric Investigation Plan in less than three months, preserving the Company’s planned 2026 UK MAA timetable and incorporating the agency’s feedback into the planned open-label Phase 3 confirmatory trial.

Completed preparations for the Phase 3 trial of Ebstrocel in RDEB remaining on track for first patient treatment in Q4 2026.

Advanced the CORDStrom™ platform patent application into the U.S. national phase following a favorable international Written Opinion. If granted, the patent family is expected to provide broad platform protection, including composition-of-matter and method-of-treatment claims, extending into at least 2045.

Expanded the Company’s agreement with Anthony Nolan Cord Blood Bank, securing long-term access to high-quality umbilical cord tissue to support scalable global development and commercialization of the CORDStrom™ platform.

Established a Scientific Advisory Board comprising internationally recognized leaders in MSC biology, clinical translation, manufacturing, potency assessment and rare pediatric skin disease. Chaired by Professor Mark Lowdell, the working SAB will support Ebstrocel’s late-stage regulatory and clinical development, including Phase 3 design, biomarkers, manufacturing consistency and product-release criteria, while helping prioritize additional indications for the CORDStrom platform. The SAB adds substantial independent expertise as the Company advances Ebstrocel toward regulatory submissions and expands CORDStrom into additional disease-specific cell therapies.

XPro1595 Platform Highlights (XPro™):

Reported a statistically significant treatment effect on a white matter myelin MRI biomarker in the Phase 2 MINDFuL trial. XPro™ demonstrated an effect in the full modified intent-to-treat population (p=0.0028; Cohen’s d=0.46; n=200), with a larger effect in the biomarker-enriched population (p=0.0098; d=0.59; n=100), supporting the precision-medicine strategy for the planned registrational program.

Published the Phase 2 MINDFuL results in NPJ Dementia. In the pre-specified, protocol-defined Alzheimer’s Disease with inflammation (ADi) subgroup, XPro™ showed directionally consistent benefit across cognitive, global, functional, behavioral and biomarker endpoints over 24 weeks, with zero ARIA-E and zero ARIA-H observed.

Presented expanded Phase 2 imaging analyses at the Alzheimer’s Association International Conference showing concordant treatment-related effects across independent white matter and cortical gray matter measures at Week 24, strengthening evidence of early biologic activity and tissue-level target engagement.

Received FDA Fast Track designation for XPro™ (pegipanermin) for early Alzheimer’s disease, encompassing mild cognitive impairment due to Alzheimer’s disease and mild Alzheimer’s disease dementia, enabling more frequent FDA interactions and potential eligibility for expedited review mechanisms.

Published a Department of Defense-funded, peer-reviewed Journal of Neurotrauma study showing that XPro1595 prevented the injury-induced rise in amyloid pathology and improved early cognitive and pain-related outcomes in a preclinical model linking traumatic brain injury to Alzheimer’s disease.

Presented AACR 2026 preclinical data showing that INB03 (XPro1595 for oncology) enhanced the activity of HER2-targeted tyrosine kinase inhibitors and reduced metastatic spread to the brain, lungs and liver in HER2-positive breast cancer models.

Corporate:

Received an approximately US$4.2 million research and development tax rebate from Australia during July 2026, providing non-dilutive capital to support ongoing development activities.

Announced it has been named a founding member of the American Biotech Innovation Alliance (ABIA). The newly launched national coalition brings together biotechnology leaders with the shared objective of defining a national strategy to sustain and extend U.S. leadership in biotech innovation.

Upcoming Events and Milestones:

• Submit the Ebstrocel™ Marketing Authorization Application to the UK MHRA by the end of Q3 or early Q4 2026, followed by a planned European Union submission to the EMA in Q1 2027.
• Ebstrocel™ Biologics License Application (BLA) submission to the FDA expected in Q1 2027.
• Submit the registrational Phase 2b/3 protocol for XPro™ in early Alzheimer’s disease to the FDA in [Q4 2026].
• Submit for publication the Phase 2 MINDFuL imaging analyses, including the white matter and cortical gray matter findings presented at AAIC 2026.
  
  

Financial Results for the Second Quarter Ended June 30, 2026:

• Net loss attributable to common stockholders for the quarter ended June 30, 2026 was approximately $1.3 million, compared to approximately $24.5 million for the quarter ended June 30, 2025. The prior-year period included a $16.5 million impairment charge related to acquired in-process research and development intangible assets.
• Research and development expenses totaled approximately $(0.8 million) for the quarter ended June 30, 2026, compared to approximately $5.8 million for the quarter ended June 30, 2025. The research and development benefit during the 2026 period was primarily due to the recognition of additional Australian research and development tax rebate.
• General and administrative expenses were approximately $2.3 million for each of the quarters ended June 30, 2026 and June 30, 2025.
• As of June 30, 2026, the Company had cash and cash equivalents of approximately $18.4 million.
• As of August 6, 2026, the Company had approximately 27.8 million common shares outstanding.
