Study Overview
=================
Brief Summary
-----------------
An Open-label, One-sequence, Three-period, Multiple-dose Study to Evaluate Drug-drug Interactions, Safety and Tolerability between NDC-002A/NDC-002B and NDC-002C in Healthy Volunteers

Detailed Description
-----------------
This is an Open-label, One-sequence, Three-period, Multiple-dose Study and the goal of this clinical trial is to evaluate in health Volunteers. The main question[s] it aims to answer are: Drug-drug Interactions Safety Tolerability The study consisted of Three-period: Period 1 which repeated administration of NDC-002C for 7 days and Period 2 which repeated administration of NDC-002A for 7 days, followed by administration of NDC-002B for 8 days and Period 3 which repeated concomitant administration of NDC-002B and NDC-002C for 7 days.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: NDC-002<br>In Period 1, Two tablets of NDC-002C are repeatedly administered once a day for seven days to reach a steady state of NDC-002C. There is a seven-day washout period between Period 1 and Period 2. In Period 2, after repeated administration of one tablet of NDC-002A once a day for seven days, one tablet of NDC-002B is administered repeatedly once a day for eight days to reach a steady state of NDC-002B. In Period 3, after the completion of Period 2 administration and without a washout period, one tablet of NDC-002B and two tablets of NDC-002C administered repeatedly in combination once a day for seven days. | Drug: NDC-002<br>* Combination of NDC-002B and NDC-002C<br>|
