About

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.

Full description

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).

Enrollment: 31 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

  • Coagulation: Prothrombin time (PT) or International Normalization Ratio (INR) ≤1.5 x ULN (≤3.0 x for those receiving anticoagulant drugs such as warfarin); 8. Female subjects must have a urine or blood HCG negative test (except for menopause and hysterectomy); 9. Subjects and their partners must agree to use effective contraceptive measures during the study until 6 months after the end of the last dose.

Exclusion criteria

• 1. History of severe allergy to mitoxantrone hydrochloride or liposomal drugs; 2. Cerebral or meningeal metastases; 3. History of allogeneic organ transplantation or allogeneic bone marrow transplantation; 4. Life expectancy < 12 weeks; 5. Subjects with chronic hepatitis B (HBsAg or HBcAb positive with HBV DNA ≥ 1000 IU/mL), hepatitis C (HCV antibody positive with HCV RNA above the lower limit of detection of the study center), or human immunodeficiency virus (HIV) antibody positive;; 6. AEs from the previous treatment > Grade 1 based on CTCAE (except for the toxicity without safety risk judged by the investigator, such as alopecia, hyperpigmentation); 7. Active bacterial, fungal or viral infections that require systemic treatment within 1 week prior to the first dose; 8. Local or systemic anticancer treatment within 4 weeks prior to the first dose (within 2 weeks prior to dosing for traditional Chinese medicine or proprietary Chinese medicine); 9. Enrolled in any other clinical trials within 4 weeks prior to the first dose; 10. Thrombosis or thromboembolism within 6 months prior to screening; 11. History of, or known additional malignant tumor within 3 years, except for locally curable tumors that have been cured, such as basal or squamous cell skin cancer or in situ prostate, cervical or breast cancer; 12. Impaired cardiac function or serious cardiac disease:

  • Long QTc syndrome or QTc interval > 480 ms;

  • Severe, uncontrolled arrhythmias requiring pharmacological treatment;

  • History of chronic congestive heart failure, NYHA ≥ grade 3;

  • Cardiac ejection fraction < 50% within 6 months prior to screening;

  • Heart valve disease with CTCAE ≥ grade 3;

  • Uncontrollable hypertension (defined as a measured systolic blood pressure ≥ 160 mmHg or diastolic blood pressure ≥ 100 mmHg under pharmacological control);

  • ECG evidence of myocardial infarction, unstable angina, history of severe pericardial disease, and acute ischemic or severe conduction system abnormalities within 6 months prior to screening; 13.

    14. Pregnant or lactating female; 15. Serious and/or uncontrolled medical condition that, in the judgment of the investigator, may affect the patient's participation in this study (including, but not limited to: diabetes not effectively controlled, kidney disease requiring dialysis, severe liver disease, life-threatening autoimmune and bleeding disorders, substance abuse, neurological disorders, etc.); 16. Not suitable for this study as decided by the investigator due to other reasons.
