This is an interventional treatment trial for Relapsing Multiple Sclerosis Read More

Inclusion Criteria:

• 18 to 55 years of age (inclusive);
• Diagnosis of relapsing multiple sclerosis (RMS);
• Disease duration of secondary progressive multiple sclerosis (SPMS) with superimposed relapses ≤ 5 years;
• Expanded disability status scale (EDSS) score of 3 to 8;
• Participants who have received disease-modifying therapy still relapse or aggravate; or participants who, in the opinion of the investigator, are suitable for treatment with Mitoxantrone Hydrochloride Liposome Injection;
• Participants voluntarily sign informed consent, and complete the study according to the protocol.

Exclusion Criteria:

• Pregnant or lactating female participants or participants planning to have a child during the study;
• History of severe drug allergy, or allergy or intolerance to gadolinium, anthracyclines or liposome drugs;
• History of vitamin B12 deficiency;
• Participants with malignant tumor diagnosed within 5 years before the screening phase, except the skin basal cell carcinoma under effective control, and Stage I Squamous Cell Carcinoma);
• Participants with history of interstitial lung disease or with pneumonia according to chest X-ray in the screening phase;
• Participants with serious or active skin diseases, or clinically significant skin abnormalities in physical examination in the screening phase;
• History of severe immunodeficiency;
• History of drug and/or alcohol abuse, or mental disorder;
• Participants has a progressive neurological disorder or optic neuritis other than MS; or has other disease that should be treated more preferentially than MS, or that could interfere with the study or compromise participants compliance with treatment;
• MRI before randomization shows cervical spinal cord compression or lesions in non-MS characteristic areas of the brain, and the lesions can explain the changes in clinical symptoms and signs;
• MS relapse in the screening phase;
• Participated in other drug clinical studies and received investigational product within 3 months before screening or within 5 half-lives of the investigational product (whichever was longer), or participated in medical device clinical studies which is judged by the investigator to have a possible impact on the results of this study;
• Participants who have received disease-modifying therapy or immunosuppressive agents or systemic corticosteroids within the washout period before the first dose (e.g., 4 weeks for interferon, PEGylated interferon, glatiramer acetate, dimethyl fumarate and 12 weeks for fingolimod, siponimod, intravenous immunoglobulin or plasma exchange, etc.)
• Participants who have received anthracyclines or cardiotoxic drugs before screening;
• Participants who previously received total body irradiation or total lymphatic irradiation, or received stem cell therapy or any type of bone marrow transplantation, or received solid organ transplantation;
• Presence of the following clinically significant diseases: myocardial infarction, acute coronary syndrome, viral myocarditis, pulmonary embolism within 6 months; coronary revascularization within 6 months; arrhythmia requiring Class Ia or Ш antiarrhythmic drugs;
• Laboratory tests in screening phase, such as white blood cell count, neutrophil count, platelet count, hemoglobin, creatinine clearance, etc., are abnormal with clinical significance (according to the judgment of the investigator); positive results for Hepatitis B Surface Antigen (HBsAg), Hepatitis C Antibody (HCVAb), syphilis antibody test; total bilirubin > 1.5x ULN, or alanine aminotransferase or aspartate aminotransferase > 3x ULN;
• Participants could not complete MRI scan before randomization, such as participants with claustrophobia;
• Participants with active or uncontrolled infection (defined as requiring systemic anti-infective therapy and the temperature ≥ 38℃ (axillary temperature) before receiving drugs and unexplainable);
• Investigator believe that participants have other disease that are not suitable for participating in this study.
