A Study of Mitoxantrone Hydrochloride Liposome Injection in the Treatment of Relapsed Ovarian Cancer

A Multicenter, Open-label, Single-arm, Phase Ib Study to Evaluate the Safety and Efficacy of Mitoxantrone Hydrochloride Liposome Injection in Subjects With Platinum-Resistant or Platinum-Refractory Relapsed Ovarian Cancer

This is a multicenter, open-label, single-arm, phase Ib study to evaluate the safety and efficacy of Mitoxantrone Hydrochloride Liposome in subjects with Platinum-Resistant or Platinum-Refractory Relapsed Ovarian Cancer.

This is a multicenter, open-label, single-arm, phase Ib study to evaluate the safety and efficacy of Mitoxantrone Hydrochloride Liposome in subjects with Platinum-Resistant or Platinum-Refractory Relapsed Ovarian Cancer. 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). All patients will receive the treatment until disease progression, intolerable toxic reaction, death, or withdrawal by investigator or patient decision (a maximum of 8 cycles). Delays in drug administration is allowed from the cycle 2, however, the delays should be no more than 3 weeks. Dose adjustments after the cycle 2 is permitted, and the minimum dose is 12mg/m2.

4. Fail to respond to or progressed on the standard platinum-based therapy ;
5. At least one measurable lesion according to RECIST v1.1;
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);
9. Adequate organ function;
10. Subjects of childbearing potential must agree to use effective contraceptive measures. Female subjects must have a negative pregnancy test before enrolment;
11. Fully comply with the protocol.

6. Serious infection or interstitial pneumonia within 1 week prior to the first dose administration;
7. Use of other anticancer treatment within 4 weeks prior to the first dose administration;
8. Enrolled in any other clinical trials within 4 weeks prior to the first dose administration;
9. Major surgery within 3 months prior to the first dose administration, or have a surgical schedule during the study period;
10. Thrombosis or thromboembolism within 6 months prior to screening;
11. History of, or known additional malignant tumor within 3 years, except for tumors have been cured and have not recurred, and carcinoma in situ;
