NCT03829384

Brief Summary

This is a Phase 1, FIH, single-center, randomized, placebo controlled, dose escalation study to evaluate the safety, tolerability, PK, and PD of mRNA-1944 in healthy adult subjects. Cohorts of mRNA-1944 are planned to be investigated in a sequential dose escalation manner.
