Summary

This study aims to evaluate the safety and pharmacokinetic characteristics of DWJ1622, DWC202313, and DWC202314 in healthy adult volunteers under fed conditions.

Detailed description

This is an open-label, randomized, oral, single-dose, 2-sequence, 2-period, crossover Phase 1 study to evaluate the pharmacokinetics and safety profiles of DWJ1622, DWC202313, and DWC202314 in healthy volunteers under fed conditions. Subjects will be randomized to receive either DWJ1622 or the co-administration of DWC202313 and DWC202314 in different sequences across two study periods with an appropriate washout period. The primary pharmacokinetic endpoints include the maximum observed plasma concentration (Cmax) and the area under the plasma concentration-time curve to the last measurable concentration (AUClast) of each study drug. Secondary endpoints include the area under the plasma concentration-time curve extrapolated to infinity (AUCinf), the ratio of AUClast to AUCinf (AUClast/AUCinf), the time to reach maximum plasma concentration (Tmax), and the terminal elimination half-life (t1/2). Safety will be evaluated based on adverse events and clinical laboratory tests.
