The Effects of Multiple Doses of Lomecel‐B, Longeveron’ s Cell‐based Therapy, on Alzheimer’s disease: Study Design and Rationale of this Phase 2a Multi‐ center Clinical trial.

Lomecel‐B is an allogeneic medicinal signaling cell (MSC) formulation under clinical investigation for Alzheimer’s disease (AD). We have successfully completed a double‐blinded, placebo‐controlled Phase 1 safety trial, in which Lomecel‐B was found to be safe and tolerable in patients with mild AD, and yielded preliminary evidence supporting potential efficacy. Mechanistically, this included evidence of pro‐vascular and anti‐inflammatory activities. Extending upon these promising results, we present the rationale and design of the next‐phase 2a trial in this program.
