Executive Commentary
"We believe the market opportunity for EXPRO in early Alzheimer’s disease has increased to nearly 70% of patients based on APOE4 status alone, a substantial expansion from prior estimates of 40%. This positions us uniquely in a growing market segment with unmet needs, especially among APOE4 homozygous patients excluded from current anti-amyloid therapies."
Dr. R.J. Tessie, Chief Executive Officer
"The CarePC trial continues to progress well, with INKmune demonstrating excellent safety and early signals of tumor lesion resolution. Concurrently, we are scaling up manufacturing capabilities for both INKmune and Cordstrom, enabling cost-effective commercial readiness."
Dr. Mark Lodell, Chief Scientific Officer
Strategic Positioning
1. Expanding Alzheimer’s Disease Market Through Biomarker-Driven Targeting
INmune Bio’s MINDFuL Phase 2 trial has revealed that APOE4 positivity—a key enrollment criterion—applies to over two-thirds of early Alzheimer’s patients, increasing the addressable market for EXPRO from 40% to nearly 70%. This biomarker-based stratification enhances patient targeting precision, a critical factor for regulatory approval and commercial uptake. Notably, APOE4 homozygous patients, representing approximately 15% of the population, are excluded from current anti-amyloid therapies in Europe and the UK, positioning EXPRO as a potentially exclusive therapeutic option for this underserved subgroup.
2. Clinical and Regulatory Momentum Across Platforms
Beyond Alzheimer’s, INmune Bio is advancing the INKmune platform in metastatic castration-resistant prostate cancer, with Phase 2 enrollment on track for completion this year. Manufacturing transitions to a UK government incubator facility will support future clinical and commercial supply. Cordstrom, targeting RDEB, has received orphan drug and rare pediatric disease designations, with a Biologics License Application (BLA) planned for early 2026. Regulatory engagement with the FDA has clarified the pathway for Cordstrom’s approval, supported by robust clinical data from a double-blind placebo-controlled trial.
3. Manufacturing Synergies and Commercial Readiness
The company is leveraging shared manufacturing platforms for INKmune and Cordstrom, optimizing resource utilization and cost efficiency. This rotational manufacturing campaign enables scalable, cGMP-compliant production to meet anticipated demand. The partnership with Cell and Gene Therapy Catapult further enhances commercial readiness by scaling Cordstrom manufacturing capabilities.
