Optimize Study - Orelabrutinib Combined With BR/G in Untreated Marginal Zone Lymphoma (MZL)

Recruiting now · Phase 2

Conditions studied: Marginal Zone Lymphoma

In brief

This is a multi-center, prospective cohort study. The main purpose of Cohort A is to evaluate the efficacy and safety of Orelabrutinib combined with BR (bendamustine and rituximab) for previously untreated young patients with MZL; the purpose of Cohort B is to assess the efficacy and safety of Orelabrutinib combined with G (Obinutuzumab) followed by Orelabrutinib maintenance therapy for previously untreated elderly patients with MZL.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• For Cohort A: Age 18-70 years, physical condition assessed by a physician as suitable for chemotherapy; for Cohort B: Age 70 or older or under 70 years of age assessed by a physician as unsuitable for chemotherapy.
• Gender is not limited.
• Confirmed by histopathology, marginal zone lymphoma including MALT, SMZL, NMZL.
• Progression, recurrence after local treatment, or unsuitable for local treatment (local treatments include surgery, radiotherapy, Helicobacter pylori treatment, hepatitis C treatment).
• ECOG performance score 0-3 points (if the score is 3 points, the physician needs to assess that the deterioration of physical condition is mainly due to tumor burden).
• Indications for treatment (with B symptoms, blood cell decline, bleeding, large mass, rapid progression of tumors, etc.).
• Major organ functions meet the following criteria: a) Complete blood count: Absolute neutrophil count ≥1.5×10\^9/L, platelets ≥75×10\^9/L, hemoglobin ≥75g/L; if accompanied by bone marrow involvement, absolute neutrophil count ≥1.0×10\^9/L, platelets ≥50×10\^9/L, hemoglobin ≥50g/L. b) Blood 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. c) Coagulation function: International normalized ratio (INR) ≤1.5 times ULN.
• Life expectancy ≥3 months.
• Voluntarily sign a written informed consent form before the trial screening.

You may not qualify if…

• Currently or previously have other malignant tumors, unless radical treatment has been performed and there is evidence of no recurrence or metastasis within the last 5 years.
• Lymphoma involving the central nervous system or transformation to a higher grade.
• Have uncontrollable or significant cardiovascular diseases, including: a) Within 6 months before the first administration of the study drug, there is a history of New York Heart Association (NYHA) class II or above congestive heart failure, unstable angina, myocardial infarction, or arrhythmias requiring treatment at the time of screening, with a left ventricular ejection fraction (LVEF) \<50%. b) Primary cardiomyopathy (such as dilated cardiomyopathy, hypertrophic cardiomyopathy, arrhythmogenic right ventricular cardiomyopathy, restrictive cardiomyopathy, unclassified cardiomyopathy). c) A history of clinically significant QTc interval prolongation, or a QTc interval \>470ms in females and \>450ms in males during the screening period. d) Symptomatic or medication-requiring coronary artery heart disease subjects. e) Subjects with uncontrollable hypertension (despite lifestyle improvements and the use of reasonable, tolerable, and adequate doses of three or more antihypertensive drugs, including diuretics, for more than 1 month, blood pressure is still not at the standard, or it is only effectively controlled when taking four or more antihypertensive drugs).
• Active bleeding within 2 months before screening, or currently taking anticoagulant drugs, or the investigator believes there is a clear bleeding tendency.
• History of deep vein thrombosis or pulmonary embolism within the past six months.
• Clinically significant gastrointestinal abnormalities that may affect the intake, transport, or absorption of drugs (such as inability to swallow, chronic diarrhea, intestinal obstruction), or subjects who have undergone total gastrectomy.
• History of organ transplantation or allogeneic bone marrow transplantation.
• Major surgery within 6 weeks before screening or minor surgery within 2 weeks before screening. Major surgery is surgery that uses general anesthesia, but endoscopic examinations for diagnostic purposes are not considered major surgery. Insertion of vascular access devices will be exempt from this exclusion criterion.
• Active infection or uncontrolled HBV (positive for HBsAg and/or HBcAb with positive HBV DNA titer), positive for HCV Ab, HIV/AIDS, or other serious infectious diseases; define active infection.
• Subjects currently with pulmonary fibrosis, interstitial pneumonia, pneumoconiosis, radiation pneumonitis, drug-related pneumonia, etc., that seriously affect lung function.
• Previously treated with BTK, BCR pathway inhibitors (such as PI3K, Syk), and BCL-2 inhibitors.
• Pregnant, breastfeeding women, and subjects of childbearing age who are unwilling to take contraceptive measures.
• Need to continuously take drugs with moderate to severe inhibitory effects on cytochrome P450 CYP3A or strong inductive effects.
• Other situations deemed unsuitable for participating in this trial by the investigator.
