This is a multicenter, open-label, single-arm, phase Ib study to evaluate the safety and efficacy of Mitoxantrone Hydrochloride Liposome in subjects with advanced gastric carcinoma. At least 30 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).

6. ECOG performance status of 0 to 2;
7. Life expectancy ≥ 12 weeks;
8. AEs from the previous treatment have resolved to ≤ Grade 1 based on CTCAE (except for the toxicity without safety risk judged by the investigator, such as hair loss, hyperpigmentation);
