Using Zanubrutinib to maintain remission in patients with Mantle Cell Lymphoma

Zanubrutinib for Maintenance Therapy in Patients With Mantle Cell Lymphoma Who Have Remission After First-line Immunochemotherapy- a Multicenter, Prospective, Phase II Study

This study is testing if Zanubrutinib can help people with mantle cell lymphoma stay in remission after their initial treatment.

Quick facts

• Phase: Phase 2
• Study type: Interventional
• Enrollment: 52 (estimated)
• Ages: 18 Years and up
• Sex: All
• Sponsor: Fudan University (Academic / other)
• Drugs / interventions: Zanubrutinib, prednisone
• Locations: 2 sites (Shanghai, Shanghai Municipality and 1 other locations)
• Trial ID: NCT06341556 on ClinicalTrials.gov

What this trial studies

This study evaluates the effectiveness of Zanubrutinib as a maintenance therapy for patients with mantle cell lymphoma who have achieved remission after first-line immunochemotherapy. Participants will receive Zanubrutinib monotherapy for a duration of two years or until disease progression, intolerable toxicity, or other specified reasons. The primary goal is to assess whether this treatment can improve the two-year progression-free survival rate. Additionally, the study will explore the safety and efficiency of the therapy.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with histologically confirmed mantle cell lymphoma who have achieved a complete or partial response after first-line immunochemotherapy.

Not a fit: Patients who have not achieved remission or those with severe organ dysfunction may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly enhance the duration of remission for patients with mantle cell lymphoma.

How similar studies have performed: Other studies have shown promising results with similar maintenance therapies in hematologic malignancies, suggesting potential for success in this approach.

Eligibility criteria

Inclusion Criteria:

* Age ≥ 18 years old;
* Histologically confirmed mantle cell lymphoma (MCL);
* Achieved complete response (CR) or partial response (PR) through first-line sufficient treatment (including immunochemotherapy with CD20 monoclonal antibody for at least 4 cycles). Frontline induction programs include but are not limited to: R-CHOP/R-DHAP, R-CHOP, BR, etc. Previous autologous hematopoietic stem cell transplantation is allowed;
* ECOG 0-2;
* Signed informed consent form;
* Having sufficient organ function: a) Hematopoietic function: Neutrophils ≥ 1.0 × 109/L, PLT ≥ 50 × 109/L, Hb ≥ 80g/L; b) Liver function: bilirubin ≤ 1.5 times the upper limit of normal (ULN), ALT and AST\<3 x ULN, serum albumin ≥ 30 g/L; c) Renal function: serum Cr\<1.5 × ULN, creatinine clearance rate ≥ 50mL/min (calculated according to the standard Cockcroft Gault formula, if renal dysfunction is caused by tumor compression, creatinine clearance rate ≥ 30mL/min); d) Left ventricular ejection fraction (LVEF) ≥ 50% detected by echocardiography; e) Coagulation function (unless the subject is receiving anticoagulant therapy and the coagulation parameters (PT/INR and APTT) are within the expected range of anticoagulant therapy at the time of screening): International standardized ratio (INR) ≤ 1.5 x ULN; Activated partial thromboplastin time (APTT) ≤ 1.5 x ULN.

Exclusion Criteria:

* Individuals who are allergic to human or mouse monoclonal antibodies and have been confirmed to be allergic to Zanubrutinib capsules and/or their excipients;
* Recent major surgery (within 4 weeks prior to enrollment), excluding diagnostic surgery;
* Uncontrollable concurrent diseases (cardiovascular and cerebrovascular diseases, blood coagulation disorders, severe infectious diseases) include but are not limited to: severe acute or chronic infections requiring systemic treatment, symptomatic congestive heart failure (New York Heart Association classification III-IV) or symptomatic or poorly controlled arrhythmias Uncontrolled arterial hypertension (systolic blood pressure ≥ 160mmHg or diastolic blood pressure ≥ 100mmHg), unstable angina, active peptic ulcer, or hemorrhagic disease even after receiving standardized treatment;
* Serious accompanying diseases that interfere with conventional treatment;
* Has a history of active malignant tumors. Except for patients with skin basal cell carcinoma, superficial bladder cancer, skin squamous cell carcinoma or cervical carcinoma in situ who have received possible curative treatment and have no disease recurrence within 3 years since the start of treatment;
* Known to have active interstitial pneumonia;
* Known cases of alcohol or drug abuse;
* Active chronic hepatitis B infection (defined as HBV DNA positive): If hepatitis B virus (HBV) DNA cannot be detected during screening, patients with latent or previous hepatitis B infection (defined as positive hepatitis B surface antigen or hepatitis B core total antibody) can be included in this study. The above patients must voluntarily undergo regular HBV-DNA testing and receive appropriate antiviral treatment according to regulations. For patients with positive hepatitis C virus (HCV) antibody serological test, only when polymerase chain reaction (PCR) shows negative HCV-RNA can participate in this study.
* Patients with active HIV and syphilis infections;
* Pregnant or lactating women;
* live vaccine administered within 4 weeks prior to administering the investigational drug, inactivated virus vaccines such as for seasonal influenza are allowed;
* Continuous corticosteroid treatment currently being received, with a dose greater than 30mg/day of prednisone or equivalent medication for at least 10 days of continuous treatment;
* Suffering from active autoimmune diseases that require systematic treatment within the past 2 years (Hormone replacement therapy is not considered as a systematic treatment, such as type I diabetes, hypothyroidism patients who only need thyroid hormone replacement therapy, patients with adrenocortical or pituitary dysfunction who only need physiological dose of glucocorticoid replacement therapy can be included in the group, and patients with autoimmune diseases who do not need systematic treatment in the past 2 years can be included in the group);
* Patients with swallowing disorders who are unable to take medication orally for a long time;
* Individuals with mental disorders who affect compliance and are unable to obtain informed consent;
* The researcher determined that patients are not suitable to participate in this study.
