Longeveron LLCPhase 2a data show laromestrocel reduced neuroinflammation in Alzheimer's patients, with FDA RMAT designation and aligned Phase 3 design.

Longeveron announced that its cellular therapy laromestrocel reduced neuroinflammation in patients with mild Alzheimer’s disease, according to new post-hoc analysis of Phase 2a trial data presented at the 2026 Alzheimer’s Association International Conference. The poster presentation showed that free water, an MRI marker of brain inflammation, rose in the placebo group over 39 weeks but was numerically reduced in all laromestrocel treatment groups, with the anti-inflammatory effect most prominent in the hippocampus, temporal lobe, and other Alzheimer’s-associated regions. The reduction in free water correlated with increased brain volume and improved cognitive and quality of life scores. Blood biomarker analysis indicated a reduction in neurogranin, a marker of neuronal degradation, and an increase in the anti-inflammatory cytokine IL-13 in treated patients. Longeveron has received U.S. FDA Regenerative Medicine Advanced Therapy designation for its Alzheimer’s program and has aligned on a Phase 3 study design.
