Testing a New Gold Nanoparticle-Based Lithium Delivery Method for Bipolar Disorder in Laboratory Models

Sponsor: Fondazione Policlinico Universitario Agostino Gemelli IRCCS

Summary

This preclinical translational study aims to evaluate a new method of delivering lithium using gold nanoparticles for the treatment of bipolar disorder. Lithium is an effective treatment for bipolar disorder, but its clinical use is limited by a narrow therapeutic range and the risk of side effects. The study will investigate whether gold nanoparticles carrying lithium can improve lithium delivery to brain cells while reducing exposure to other tissues. The research will use human induced pluripotent stem cell (iPSC)-derived neural cells generated from blood samples collected from people with bipolar disorder and healthy volunteers, as well as a mouse model of mania. No participants will receive the investigational treatment. Human participants will provide blood samples only for the generation of laboratory cell models. The study will compare the effects of nanoparticle-delivered lithium with conventional lithium salts on cellular lithium uptake, disease-related molecular and functional changes, and biomarkers associated with bipolar disorder. The hypothesis is that lithium delivered by gold nanoparticles will achieve greater therapeutic effects at lower systemic lithium exposure than conventional lithium formulations, providing proof of concept for a safer and more targeted lithium delivery strategy for future clinical development.
