There are heart diseases that require treatment at the time of screening, such as unstable angina, chronic congestive heart failure (NYHA ≥ grade 2), arrhythmia, valvular disease, etc. or persistent cardiomyopathy; 3. QTc interval >480ms or suffering from long QTc syndrome during screening; 4. The cardiac ejection fraction is lower than 50% or lower than the lower limit of the examination value range of the research center during screening. 2. Active infection of hepatitis B and hepatitis C (hepatitis B virus surface antigen is positive and hepatitis B virus DNA exceeds 1x103 copies/mL; hepatitis C virus RNA exceeds 1x103 copies/mL); 3. Human immunodeficiency virus (HIV) infection (HIV antibody positive); 4. Suffer from uncontrollable bacterial infection, fungal infection or viral infection that requires systemic treatment within 1 week before the administration of the study drug; 5. Women who are pregnant or breastfeeding; 6. Peripheral neuropathy or pain of grade 2 (CTCAE5.0) or above before treatment; 7. Received systemic chemotherapy within 28 days before the first dose; 8.

This study is expected to be carried out from November 2023 to November 2026. About 30 patients with high-risk/extramedullary multiple myeloma will receive mitoxantrone Hydrochloride Liposome combination regimen treatment. After evaluating of efficacy and safety of treatment, the principal investigator will write and publish the paper.

Arms

Experimental: Lipo-MIT combination regimen group

Initial diagnosis induction treatment regimen Lipo-MIT +VD (VMD): Mitoxantrone Hydrochloride Liposome: 10 mg, d1, d15, intravenous infusion; Bortezomib: 1.3mg/m2 d1, 4, 8, 11, subcutaneous injection; Dexamethasone: 20 mg/d, orally on days 1, 2, 4, 5, 8, 9, 11, and 12.
