Study Summary

The goal of this clinical trial is to assess the safety and effects of a crystalized form of lithium, AL001, when compared to commonly used Lithium Carbonate in healthy volunteers. The main questions this study aims to answer are: How safe and effective is AL001 when compared to Lithium Carbonate? How is AL001 broken down in the brain and body compared to Lithium Carbonate? Participants will be asked to: * Take both the study drug (AL001) and Lithium Carbonate each for a period of 14 days * Stay overnight at MGH's research unit for two separate 2-week periods * Participate in two separate 24 hour periods of multiple MRIs and blood draws

Primary Outcome

• Brain (and brain structures)-to-plasma ratios between AL001 and lithium carbonate for steady-state PK measures/ parameters.

Interventions

  • DRUG AL001
  • DRUG Lithium Carbonate Capsule
