This is a multicenter, open-label, phase Ib study to evaluate the safety and efficacy of Mitoxantrone Hydrochloride Liposome in subjects with unresectable or metastatic bone and soft tissue sarcoma who has failed at least one prior line of therapy. About 50 subjects will be recruited in this study. The subjects will receive Mitoxantrone Hydrochloride Liposome 20 mg/m2 by an intravenous infusion (IV), every 21 days (q3w, 1 cycle). All the subjects will receive the treatment until disease progression, intolerable toxicity, death, or withdrawal by investigator or subject decision (a maximum of 6 cycles).
