This trial is an open-label, single-center, dose-escalation and cohort-expansion Phase I clinical study in patients with advanced solid tumors. The aim of this study is designed to evaluate the safety, tolerability, pharmacokinetics and preliminary antitumor activity of albumin-bound formulation of docetaxel for intravenous infusion in patients with advanced solid tumors.

This study was 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 with advanced solid tumors will be assigned to receive sequentially higher doses of albumin-bound formulation of docetaxel once every three weeks (a Cycle) by intravenous infusion, starting at a dose of 50mg/m2. Patients will receive the albumin-bound formulation of docetaxel
