Overview

Brief Summary

This is a Phase 1, single-center, open-label, single-arm, dose-escalation positron emission tomography study to assess the safety and tolerability, immunogenicity, Pharmacokinetics, dosimetry, and biodistribution after GEH200521 (18F) Injection is co-administered with GEH200520 Injection in healthy volunteers.

The estimated study duration for each subject is approximately 28 days in part A and 34 days in part B.

The primary study objective is to evaluate the safety and tolerability of the IMPs, the selected mass doses of GEH200520 Injection co-administered with a fixed dose of GEH200521 (18F) Injection.
