A Bioequivalence Study of L04TD1 Compared to Administration of L04RD1 in Healthy Volunteers

A Randomized, Open-label, Single-dose, Two-sequence, Two-period, Cross-over Phase 1 Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of L04TD1 and L04RD1 in Healthy Adult Volunteers

This is a randomized, open, single-dose, crossover-design, phase 1, single-center study to evaluate bioequivalence after administration of L04RD1 or administration of L04TD1 in healthy volunteers.
