NCT ID NCT07364851
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-stage study tests two experimental drugs (DW4421-T1 and DW4421S-T1) in 38 healthy adults aged 19 to 50. The goal is to check how safe they are and how the body processes them. Participants will receive a single dose of each drug in a random order and be monitored closely. No treatment benefit is expected, as this is purely a safety and drug-level study.
