Overview
To evaluate the efficacy and safety of mitoxantrone Hydrochloride Hydrochloride Liposome combination regimen in the treatment of high-risk/extramedullary multiple myeloma
Description
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.
