Orelabrutinib as Consolidation and Maintenance Therapy in Treatment-Naïve MZL.

Recruiting now · Phase 2

Conditions studied: Marginal Zone Lymphoma (MZL)

In brief

This study aims to explore a new treatment approach for patients with treatment-naive Marginal Zone Lymphoma (MZL). MZL is a type of slow-growing lymphoma that often affects older adults. The current standard treatment involves chemotherapy, but it can have significant side effects and may not always provide long-term benefits. This study investigates a treatment strategy that combines a limited course of chemotherapy (R-CHOP) followed by consolidation and maintenance therapy with a targeted drug called Orelabrutinib. Patients will undergo a series of tests to determine eligibility for the study. These tests include blood work, imaging studies, and assessments of overall health. Eligible participants will receive a standard chemotherapy regimen called R-CHOP for three cycles. After this, the response to treatment will be evaluated. Participants who show a good response will then receive three cycles of consolidation therapy with Orelabrutinib and Rituximab (OR). Those who continue to respond well will enter a maintenance phase with Orelabrutinib for up to two years. Throughout the study, participants will be closely monitored for treatment response and any side effects. Regular check-ups, blood tests, and imaging studies will be conducted to assess the effectiveness and safety of the treatment. This study is an important step towards finding better treatment options for MZL patients. It is hoped that through this research, the quality of life and outcomes for those affected by this disease can be improved.

You may qualify if…

Histologically confirmed CD20-positive marginal zone lymphoma (MZL) that has not received systemic therapy.

Adequate organ function as defined below:
Hematology: Hemoglobin (HB) ≥60 g/L, platelets (PLT) ≥50×10⁹/L, neutrophils (NE) ≥1.0×10⁹/L (Note: Subjects with cytopenia due to lymphoma bone marrow involvement are not restricted by this criterion).
Cardiac: Left ventricular ejection fraction (LVEF) ≥50% as determined by echocardiogram.
Renal: Creatinine ≤1.5×upper limit of normal (ULN) or creatinine clearance ≥30 ml/min.

Women of childbearing potential must have a negative pregnancy test. Both male and female patients must agree to use effective contraception during the treatment period and for 2 years thereafter.
Life expectancy of more than 3 months.
Voluntary provision of written informed consent.

You may not qualify if…

Underwent major surgery or severe trauma within 2 weeks prior to enrollment, or has not yet recovered from significant adverse effects.
Has other malignancies currently or within the past 3 years, excluding those that have been cured (such as basal or squamous cell carcinoma of the skin, superficial bladder cancer, prostatic intraepithelial neoplasia, and cervical carcinoma in situ).
Has a history of stroke or intracranial hemorrhage within the past 3 months.
Requires anticoagulation with warfarin or equivalent vitamin K antagonist.
Has evidence of any comorbidities or medical conditions that may interfere with the conduct of the study or place the patient at significant risk, including but not limited to severe cardiovascular disease (e.g., New York Heart Association class III or IV heart disease, myocardial infarction within the past 6 months, unstable arrhythmia, or unstable angina) and/or severe pulmonary disease (e.g., severe obstructive pulmonary disease and a history of symptomatic bronchospasm).
Is infected with human immunodeficiency virus, or has uncontrollable active hepatitis C virus or hepatitis B virus infection.
Has uncontrollable active infection.
Is pregnant or breastfeeding.
Has any life-threatening disease, medical condition, or organ dysfunction that may jeopardize the safety of the patient, as determined by the investigator.
Has any condition that may interfere with the absorption or metabolism of orelabrutinib or place the study results at unnecessary risk.
Has central nervous system involvement by marginal zone lymphoma or evidence of disease transformation.
Has any condition that the investigator judges may interfere with the patient's full participation in the study; any condition that poses significant risk to the patient; or any condition that may interfere with the interpretation of study data.
