What this trial studies

This study investigates the safety and pharmacokinetic interactions of two drugs, DWC202313 and DWC202314, in healthy adult volunteers. It employs a two-arm, open-label, single-sequence, multiple oral dosing, crossover design to assess how these drugs affect each other's absorption and metabolism. Participants will receive both drugs in a controlled setting to gather data on their interactions. The study aims to provide insights into potential drug-drug interactions that could impact treatment regimens.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy adults aged 19 and older.

Not a fit: Patients with galactose intolerance or Lapp lactase deficiency may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of drug interactions, leading to safer medication use in patients.

How similar studies have performed: While drug-drug interaction studies are common, the specific interactions of DWC202313 and DWC202314 have not been previously tested, making this a novel investigation.
