A Study of SKLB1028 in Patients With Advanced Solid Tumor

An Open-label, Multicenter, Phase I Clinical Trial to Evaluate the Safety, Tolerability, Pharmacokinetic Characteristics and Preliminary Efficacy of SKLB1028 in Patients With Advanced Solid Tumors

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetic characteristics and preliminary efficacy of SKLB1028 in patients with advanced solid tumors.

Study Overview

• Status: Not yet recruiting
• Conditions: Advanced Solid Tumors
• Intervention / Treatment: Drug: SKLB1028

Detailed Description

This study is divided into two stages. The first stage is the dose-escalation stage to evaluate the safety, tolerance and pharmacokinetics of SKLB1028 in patients with advanced solid tumors. A classic 3+3 design will be used to determine the maximum tolerated dose (MTD). Patients with advanced solid tumors will receive SKLB1028 orally once daily (QD) in continuous 28-day cycles, starting at a dose of 200 mg and rising to 400 mg. The second stage is cohort-expansion study. The safe tolerated dose group will be selected for case expansion. At this stage, patients with advanced solid tumors with better response on SKLB1028 are mainly enrolled.

• Study Type: Interventional
