Korábbi kezelés

• Previous history of antitumor therapy meeting any of the following conditions:
  • Prior treatment with mitoxantrone or liposomal mitoxantrone;
  • Prior treatment with doxorubicin or other anthracyclines, with a total cumulative doxorubicin dose >360 mg/m² (for other anthracyclines, 1 mg of doxorubicin is equivalent to 2 mg of epirubicin);

  • Prior antitumor therapy (including chemotherapy, targeted therapy, hormone therapy, traditional Chinese medicine with antitumor activity, etc.) or participation in other clinical trials involving investigational drugs within 4 weeks or 5 half-lives (whichever is shorter) before the first dose of the study drug.
• History or concurrent presence of other malignancies (except for effectively controlled non-melanoma skin basal cell carcinoma, in situ carcinoma of the breast/cervix, and other malignancies effectively controlled without treatment in the past five years);
• Requirement for systemic corticosteroid therapy or other immunosuppressive therapy due to a medical condition within 14 days before the start of study treatment [topical use (ocular, intra-articular, intranasal, and inhaled corticosteroids with minimal systemic absorption) is permitted; short-term (≤7 days) corticosteroid use for prophylaxis (e.g., contrast agent allergy) or treatment of non-autoimmune conditions (e.g., delayed hypersensitivity due to contact allergens) is permitted];

Más betegség

• Uncontrolled systemic diseases (e.g., progressive infections, uncontrolled hypertension, diabetes, etc.);
• Human immunodeficiency virus (HIV) infection (HIV antibody positive);
• Presence of primary or secondary central nervous system (CNS) lymphoma or a history of CNS lymphoma at enrollment;
• Other conditions deemed by the investigator to be unsuitable for participation in this study.

Laborértékek

• Cardiac function and diseases meeting any of the following conditions:
  • Long QTc syndrome or QTc interval >480 ms;

  • Severe, uncontrolled arrhythmia requiring medication;
  • New York Heart Association Class ≥ III;
  • History of acute myocardial infarction, unstable angina, severe unstable ventricular arrhythmia, or any other arrhythmia requiring treatment within 6 months before enrollment; history of clinically significant pericardial disease; or electrocardiographic evidence of acute ischemic or active conduction system abnormalities.
• Active hepatitis B or C infection (hepatitis B surface antigen positive with HBV DNA >1×10³ copies/mL; HCV RNA >1×10³ copies/mL);

Egyéb

• ECOG score 0 to 2 points;
• Bone marrow function: neutrophil count >= 1.5 x 10\^9 / L, platelet count >= 75 x 10\^9 / L, and hemoglobin >= 80 g/L (neutrophil count may be extended to >= 1.0 x 10\^9 / L, the platelet count can be extended to >= 50 x 10\^9 / L, and hemoglobin can be extended to >= 75 g/L in patients with bone marrow involvement);
• Liver and kidney function: serum creatinine acuities were <= 1.5 times the upper limit of normal (ULN) value; AST and ALT <= 2.5 times the ULN(<= 5 times the upper limit of normal in patients with liver invasion); Total bilirubin <= 1.5 times the ULN (<= 3 times the upper limit of normal in patients with liver invasion);
• Blood coagulation function: International standardization Ratio (International Normalized thewire, INR) <= 1.5 x ULN; Prothrombin Time (PT), Activated PartialThromboplastin Time (APTT) <= 1.5×ULN (unless receiving anticoagulant therapy, And PT and APTT at screening were within the expected range for anticoagulant therapy).
