This is a multicenter, open-label, phase I dose-escalation and dose-expansion study aimed to evaluate the safety, tolerability, pharmacokinetics and efficacy of mitoxantrone hydrochloride liposome injection. This study consists of two phases: dose-escalation phase and dose expansion phase. The dose-escalation phase will be conducted to determine the maximum tolerated dose (MTD) of mitoxantrone hydrochloride liposome injection in patients with advanced solid tumors based on a 3+3 design. Patients enrolled in this phase will receive mitoxantrone hydrochloride liposome injection followed by a 3-week DLT observation period. After DLT observation, two to four dose cohorts will be selected for dose-expansion to further explore the safety and efficacy of study drug according to the dose-escalation results. In the dose-expansion phase, patients will receive the study drug every 3 weeks (q3w, a cycle) until disease progression, intolerable toxicity, death, or withdrawal by investigator or patient decision (a maximum of 6 cycles).
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK) and efficacy of mitoxantrone hydrochloride liposome injection in patients with advanced solid tumors.
