A Dose Escalation and Food Effect Study of SKLB1028 in Healthy Subjects

A Single-Centre, Single-Administration, Dose-Escalation Study and A Single-Centre, Randomized, Open-Label, Two-cycle Crossover Food Effect Study of SKLB1028 in Healthy Subjects

The purpose of this study was to explore the safety, tolerability and pharmacokinetics (PK) of single ascending oral doses of SKLB1028 in healthy subjects. This study has also explored the effect of food on the PK of SKLB1028.

Study Overview

• Status: Completed
• Conditions: Healthy Subjects
• Intervention / Treatment: Drug: SKLB1028

Detailed Description

The study was divided into 2 parts. Part 1(Dose Escalation) included 2 cohorts (Cohort 1 and Cohort 2) and subjects received a single oral dose of SKLB1028 50 or 100 mg on Day 1. In Part 2 (Food Effect) included 2 cohorts (Cohort A and Cohort B), subjects received a single oral dose of SKLB1028 150 mg in a fasting and a fed state, with a 10-day washout period between the 2 doses.
