Bioequivalence of DWJ1622 versus DWC202313 plus DWC202314 in fed healthy adults

An Open-label, Randomized, Fed, Single-dose, 2-sequence, 2-period, Crossover Phase 1 Study to Evaluate the Pharmacokinetics and the Safety After Administration of "DWJ1622" and Co-administration of "DWC202313" and "DWC202314" in Healthy Volunteers

Phase 1 Interventional Daewoong Pharmaceutical Co. LTD. · NCT07267221

This study will test whether a single oral dose of DWJ1622 gives similar safety and blood levels as taking DWC202313 with DWC202314 in healthy adults after a meal.

What this trial studies

This open-label, randomized, single-dose, two-sequence, two-period crossover Phase 1 trial compares oral DWJ1622 to the co-administration of DWC202313 and DWC202314 in healthy adults under fed conditions. Participants are randomized to receive each treatment in different periods with an appropriate washout while blood samples are collected for pharmacokinetic analysis. Primary endpoints are Cmax and AUClast for each drug, with secondary PK measures including AUCinf, AUClast/AUCinf, Tmax, and t1/2; safety is monitored via adverse events and clinical laboratory tests. The study is conducted at a single site in Seoul and enrolls healthy volunteers aged 19 and older.

Who should consider this trial

Good fit: Healthy adults aged 19 or older who are not pregnant or lactating and who have no history of mental disorder are ideal candidates for participation.

Not a fit: People with active medical conditions, pregnant or breastfeeding women, individuals with a history of mental disorder, or patients seeking therapeutic benefit are unlikely to receive clinical benefit from this healthy-volunteer PK study.

Why it matters

Potential benefit: If the formulations show comparable pharmacokinetics and acceptable safety, the results could support using the products interchangeably and speed their further development.

How similar studies have performed: Crossover bioequivalence and PK studies in healthy volunteers are a well-established and commonly successful approach for oral drugs, though these specific compounds appear to be novel.
