A Three-part, Single-center, Open-label, Phase I Drug-drug Interaction Clinical Study to Investigate the Effect of Itraconazole, Gemfibrozil or Rifampicin on Pharmacokinetics of SKLB1028 in Healthy Subjects

This is a three-part, single-center, open-label phase I clinical study to characterize the DDIs potential of SKLB1028 with Itraconazole, Gemfibrozil or Rifampicin in healthy subjects. This study also aims to evaluate the safety and tolerability of SKLB1028 in the presence of Itraconazole, Gemfibrozil or Rifampicin.

Study Overview

• Status: Active, not recruiting
• Conditions: Healthy Subjects
• Intervention / Treatment: Drug: SKLB1028; Drug: Itraconazole; Drug: Gemfibrozil; Drug: Rifampicin

Detailed Description

SKLB1028 is the potential substrate of CYP3A4, CYP2C8 and P-gp. This study conducted in three parts to characterize the DDIs potential of SKLB1028 with the perpetrator drugs ( Itraconazole, Gemfibrozil, Rifampicin) in Healthy Subjects. Each part of this study consists of a screening period (Day -14 to Day -2), a baseline period (Day -1), a treatment period, and a follow-up visit period.
