A Study to Evaluate the Safety and Efficacy of Docetaxel for Injection (Albumin-bound)in Different Dose Regimens in Patients With Advanced Solid Tumors

Safety, Tolerability, Pharmacokinetics and Preliminary Antitumor Activity of Docetaxel for Injection (Albumin-bound) in Different Dose Regimens in Patients With Advanced Solid Tumors: An Open-label, Multicenter, Phase 1b Study

The aim of this study is designed to evaluate the safety, tolerability, pharmacokinetics and preliminary antitumor activity of docetaxel for injection (albumin-bound) in different dose regimens in patients with advanced solid tumors.

Study Overview

• Status: Recruiting
• Conditions: Advanced Solid Tumors
• Intervention / Treatment: Drug: Albumin-bound docetaxel

Detailed Description

This study will be conducted in two stages. The first stage (Stage I) is a dose-escalation study. A classic 3+3 design will be used to determine the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D). Patients will receive the docetaxel for injection (albumin-bound) until disease progression, or intolerable toxicity, or other reasons for termination of the study. All dose-escalation decisions will be based on the safety data generated from the current highest dose group.

In the cohort-expansion study (Stage Ⅱ), patients with a potential to have better response to the study drug will be recruited. Patients will receive the docetaxel for injection (albumin-bound) at the recommended phase 2 dose (RP2D) and follow the treatment regimen established in Stage I.
