Laborértékek

• Any serious medical condition, including but not limited to:
  • Uncontrolled hypertension (defined as blood pressure that remains uncontrolled after at least 4 weeks of treatment with a reasonable and tolerable regimen of 3 or more antihypertensive agents [including diuretics] at adequate doses, or requiring 4 or more antihypertensive agents to achieve adequate control);
  • Uncontrolled congestive heart failure within 6 months prior to screening (New York Heart Association [NYHA] Class III [moderate] or Class IV [severe] cardiac disease);
  • Left ventricular ejection fraction (LVEF) < 50%;
  • Symptomatic coronary artery disease (e.g., chest tightness, chest pain, palpitations, fatigue) or coronary artery disease requiring medical therapy; ⑤Severe bradycardia (heart rate < 40 beats per minute [bpm]) with hypotension, dizziness, or syncope; patients with a history of arrhythmia should undergo cardiac evaluation;
  • Known active bacterial, viral, fungal, or other infection (excluding fungal infection of the nail bed), or major infection within 2 weeks prior to the first dose of study drug;
  • Moderate to severe hepatic impairment (Child-Pugh Class B or C); ⑧Active bleeding within 2 months prior to screening, or clear evidence of bleeding diathesis as judged by the investigator; ⑨Current pulmonary disease that impairs lung function, such as pulmonary fibrosis or drug-related pneumonitis, which is deemed intolerable by the investigator; ⑩Any psychiatric or cognitive disorder that may limit the patient's ability to understand, execute, or comply with the informed consent and study requirements;

• Pregnant or breastfeeding women;

• Voluntarily participate and sign the informed consent form;
• Age ≥ 18 years, male or female;
• Life expectancy ≥ 3 months;
• Eastern Cooperative Oncology Group (ECOG) performance status 0-2. Patients with ECOG 3 may be enrolled only if the decline in performance status is attributed to the underlying disease and the investigator determines that they may benefit from the treatment;

• Presence of measurable and/or evaluable lymphoma lesions;
• Adequate bone marrow reserve, defined as: absolute neutrophil count > 1.0×10⁹/L or platelet count > 75×10⁹/L, unless cytopenias are considered to be related to bone marrow involvement by lymphoma and deemed recoverable by the investigator;
• Hepatic function: AST (SGOT) and ALT (SGPT) ≤ 2.5 × upper limit of normal (ULN) (in the absence of liver involvement) or ≤ 5 × ULN (in the presence of liver involvement); total bilirubin (TBIL) ≤ ULN; serum creatinine (CRE) ≤ 1.5 × ULN;
• Creatinine clearance ≥ 30 mL/min, calculated using the Cockcroft-Gault formula;
• Able to comply with the study visit schedule and other protocol requirements;
• All patients of childbearing potential must agree to use effective contraceptive measures during the study and for 24 months after study treatment discontinuation. Female patients of childbearing potential must have a negative urine pregnancy test prior to the first dose of study treatment.
