Brief summary: A multicenter, single-arm, phase 2 study of mitoxantrone hydrochloride liposome injection in patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL).

Detailed description: This is a phase 2, single-arm, multicenter trial to evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in patients with R/R DLBCL. The eligible patients will receive mitoxantrone hydrochloride liposome injection (20 mg/m\^2) once every 4 weeks for a maximum of 8 cycles. Patients will receive treatment until the completion of 8 cycles of treatment, disease progression, intolerable toxicity, death, loss to follow-up, withdrawal (patient's decision or investigator's decision), whichever comes first. All patients will have post-treatment follow-up for disease status until disease progression/recurrence, initiation of new antitumor therapy, or being lost to follow-up.

Eligibility criteria: Inclusion Criteria:

1. Able to understand and comply with the study, and voluntarily sign informed consent.
2. Age ≥ 18 years old.
3. Previously treated, pathologically confirmed primary DLBCL, or DLBCL transformed from previously diagnosed indolent lymphoma (e.g., follicular lymphoma).
4. Patients are not suitable for high-dose chemotherapy combined with autologous stem cell transplantation as rescue therapy.
5. Relapsed or refractory disease after at least (≥) 2 lines of systemic therapy (including at least a regimen of anti-CD20 immunotherapy combined with cytotoxic drugs was included), there is no suitable and conventional therapy.
6. Patients have at least one measurable lesion in accordance with the Lugano evaluation criteria (version 2014):(if the only measurable lesion has received radiotherapy in the past, there must be evidence of radiological progression after radiotherapy).
7. Confirmation of no objective response from the most recent therapy (at least 2 cycles of administration, and efficacy assessed as stable disease or progressive disease) or disease progression after therapy.
8. Patients must agree to provide the most recent tumor tissue section or have a biopsy of tumor tissue.
9. Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 2.
10. Estimated life expectancy ≥ 3 months.
11. Patients should meet the following requirements and have not received infusion of cell growth factor, blood transfusion, or blood product within 14 days of the hematology test:

    1. Absolute value of neutrophils ≥ 1.5 × 10\^9/L; Hemoglobin≥80g/L; Platelet ≥ 75 × 10\^9/L;
    2. Aspartate aminotransferase (AST), alanine aminotransferase (ALT) ≤ 2.5 × ULN; AST and ALT ≤ 5 × ULN for patients with liver metastasis. Total bilirubin ≤1.5 × ULN (≤ 3 × ULN for patients with Gilbert syndrome).
    3. Creatinine clearance ≥ 50 mL/min or serum creatinine ≤ 1.5 × ULN。
    4. Coagulation function: prothrombin time or activated partial thromboplastin time≤ 1.5 × ULN, and international normalized ratio ≤ 1.5.
12. Female patients of childbearing age must have a negative pregnancy test at the time of enrollment within one week, and must agree to use an effective method of contraception from the study initiation until at least 4 months after the last treatment; Male patients must agree to use an effective method of contraception from the study initiation until at least 6 months after the last treatment. During the study, oocyte donation of female patients and sperm donation of male patients are not allowed.
13. COVID-19 patients without related symptoms after two weeks can be enrolled.
