Core Insights - The Phase 2 MINDFuL trial of XPro™ in early Alzheimer's Disease (AD) patients with inflammation biomarkers did not meet the primary cognitive endpoint in the modified intent-to-treat (mITT) population, but showed cognitive, behavioral, and biological benefits in a predefined subgroup of amyloid-positive patients with two or more inflammation biomarkers [1][3][4] Group 1: Trial Results - The MINDFuL trial enrolled 208 participants with early-stage AD, assessing XPro™'s potential to slow cognitive decline by targeting neuroinflammation [4] - In the predefined subgroup of amyloid-positive early AD patients with two or more inflammation biomarkers (n=100), XPro™ demonstrated a cognitive benefit on the primary endpoint EMACC (effect size: 0.27) and a behavioral benefit on the Neuropsychiatric Inventory (effect size: -0.24) [7] - A biological benefit was observed in blood levels of pTau217 (effect size: -0.20), indicating a positive impact on AD pathology [7] Group 2: Safety and Tolerability - XPro™ treatment was well-tolerated and safe, with no occurrences of ARIA-E or ARIA-H reported [2][7] - The most common adverse events were injection site reactions, occurring in 80% of the XPro™ group compared to less than 20% in the placebo group [7] - There were no deaths or drug-related hospitalizations during the trial, indicating a favorable safety profile [7] Group 3: Future Plans - The company plans to submit for Breakthrough Therapy designation with the FDA and will present additional analyses at the Alzheimer's Association International Conference (AAIC) in July 2025 [2][10] - The company aims to engage regulatory authorities in the UK, EU, and other regions to define the path for a pivotal trial to support XPro™ approval in early AD [14]
