Mitoxantrone Hydrochloride Liposome Containing Regimen in Patients with Adult Acute Lymphoblastic Leukemia: A Multicenter, Retrospective, Real-World Study

Background Although the initial overall response rate is high (70%-90%) in adult acute lymphoblastic leukemia (ALL) patients (pts), a large percentage of them frequently relapse. Prognosis of relapsed/refractory (R/R) ALL remains poor and there are no clear guidelines on the best treatment approach. Currently, an anthracycline-based multidrug chemotherapy regimen remains the treatment cornerstone in ALL. Mitoxantrone is a synthetic anthracenedione anti-cancer drug that is effective in lymphoma, leukemia, and other solid tumors. Mitoxantrone hydrochloride liposome (PLM60) is the first approved mitoxantrone nano-drug, which has shown favorable pharmacokinetic characteristics and significantly prolong the survival time of animals compared with the same dose of mitoxantrone. However, there is still a lack of systematic reports about the real-world application of PLM60 in ALL.
