Alzheimer's Trial Misses Mark, But Uncovers a Hidden Victory

INmune Bio’s Phase 2 MINDFuL trial did not meet its primary cognitive goal in the overall study population for early Alzheimer's disease^{1, 2}.
However, a targeted subgroup of patients with high inflammation showed significant cognitive benefits, behavioral improvements, and a reduction in key disease biomarkers^{1, 2}.
The drug, XPro™, proved exceptionally safe, avoiding the brain swelling and bleeding side effects common in other Alzheimer's treatments, charting a new course for fighting the disease^{1, 2}.

On June 30th, the Alzheimer's community held its breath for the top-line results from INmune Bio Inc.'s (NASDAQ: INMB) MINDFuL trial. The initial announcement sent a ripple of disappointment: the study had not met its primary cognitive endpoint. But buried within the data was a revolutionary discovery that could change how we fight this devastating disease.

While the overall group did not show improvement, a predefined group of patients—those with clear biological evidence of high neuroinflammation—experienced a remarkable turnaround. In this specific subgroup, XPro™ demonstrated a clear cognitive benefit over the placebo^{1, 2}. More than just slowing decline, it showed improvements in behavior and a reduction in pTau217, a critical biomarker for Alzheimer's pathology^{1, 2}.

XPro™ achieved this by taking a radically different approach. Instead of targeting amyloid plaques directly, it neutralizes soluble TNF (sTNF), a key driver of the brain's chronic, destructive inflammation⁵. Crucially, the treatment was extremely well-tolerated, with no cases of the dangerous brain swelling (ARIA-E) or bleeding (ARIA-H) that have plagued other promising therapies^{1, 2}.

This isn't a story of failure, but one of precision. INmune Bio has uncovered a powerful weapon for a specific type of Alzheimer's patient, proving that targeting inflammation is a viable and safe strategy. The company now plans to present further data and seek Breakthrough Therapy designation from the FDA, turning a perceived setback into a focused new front in the war against Alzheimer's^{1, 2}.
