Study Arms (1)
orelabrutinib combined with rituximab regimen
EXPERIMENTALAll participants will receive induction therapy with the orelabrutinib and rituximab regimen. The treatment cycle is 28 days, with a total of 6 cycles. The induction treatment period is as follows: Cycle 1: Rituximab, 375 mg/m², on Day 1. Cycles 2-6:Orelabrutinib, 150 mg, once daily orally, from Day 1 to Day 28. Rituximab, 375 mg/m², on Day 1. Patients who achieve a partial response (PR) or better will enter a 2-year maintenance period with orelabrutinib.

Patients who achieve a partial response (PR) or better will enter a 2-year maintenance period with orelabrutinib.
Eligibility Criteria
You may qualify if:
- Age ≥ 18 years, regardless of gender;
- Histologically confirmed CD20-positive marginal zone lymphoma, including MALT, SMZL, and NMZL, with at least one lesion outside the spleen measuring more than 1.5 cm in any axis;
- MZL that has progressed or relapsed after prior local therapy (including surgery, radiotherapy, anti-Helicobacter pylori treatment, and anti-hepatitis C treatment), or is not suitable for local therapy;
- ECOG performance status of 0-2;
- Presence of an indication for treatment as judged by the investigator (symptomatic, cytopenia, risk of end-organ damage, bulky disease, ongoing progression, or patient's desire for treatment);
- Adequate function of major organs, as follows:
- Hematology: Absolute neutrophil count ≥ 1.5×109/L, platelets ≥ 75×109/L, hemoglobin ≥ 75 g/L; if there is bone marrow involvement, absolute neutrophil count ≥ 1.0×109/L, platelets ≥ 50×109/L, hemoglobin ≥ 50 g/L;
- Biochemistry: Total bilirubin ≤ 1.5 times the upper limit of normal (ULN), AST or ALT ≤ 2 times ULN; serum creatinine ≤ 1.5 times ULN; serum amylase ≤ ULN;
- Coagulation: International normalized ratio (INR) ≤ 1.5 times ULN.
- Life expectancy of ≥ 3 months;
- Voluntary written informed consent obtained before screening for the trial.
You may not qualify if:
- Currently or previously having other malignancies, unless there is evidence of no recurrence or metastasis within the past 5 years after curative treatment;
- Lymphoma involvement of the central nervous system or transformation to high-grade lymphoma;
- Non-hematological toxicities from prior anti-cancer treatments not recovered to ≤ Grade 1 (excluding alopecia);
- Presence of uncontrolled or significant cardiovascular disease, including:
- New York Heart Association (NYHA) Class II or higher congestive heart failure, unstable angina, myocardial infarction within 6 months before the first administration of the study drug, or arrhythmias requiring treatment at screening, left ventricular ejection fraction (LVEF) \< 50%;
- Primary cardiomyopathy (such as dilated cardiomyopathy, hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, restrictive cardiomyopathy, unclassified cardiomyopathy);
- History of clinically significant QTc interval prolongation, or QTc interval \> 470 ms for females, \> 450 ms for males during the screening period;
- Symptomatic or medically treated coronary artery disease;
- Uncontrolled hypertension (defined as blood pressure not reaching target levels despite a reasonable and tolerable full dose of three or more antihypertensive drugs (including diuretics) for more than one month, or requiring four or more antihypertensive drugs to effectively control blood pressure).
- Active bleeding within 2 months before screening, or currently taking anticoagulant drugs, or deemed by the investigator to have a clear tendency to bleed;
- Urine protein ≥ 2+, and 24-hour urine protein quantification ≥ 2 g/24 hours;
- History of deep vein thrombosis or pulmonary embolism within the past six months;
- History of organ transplantation or allogeneic bone marrow transplantation;
- Active infection or uncontrolled HBV (HBsAg positive and/or HBcAb positive with positive HBV DNA titer), HCV Ab positive, HIV/AIDS, or other severe infectious diseases;
- Currently having pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonitis, drug-related pneumonia, or other conditions that significantly affect pulmonary function;
