Outcome Measures
Primary Outcomes (1)

up to the end of 6 cycles of treatment(each cycle is 28 days)
Best overall response rate (ORR) and complete response rate (CRR) during treatment
Up to the end of 6 cycles of treatment(each cycle is 28 days)
CRR and ORR at end of treatment
at the end of Cycle 24 (each cycle is 28 days)
Progression-free survival (PFS)
up to 5 years
Duration of response (DOR)
up to 5 years
- +4 more secondary outcomes
Other Outcomes (2)

Study Arms (1)
Experimental: Induction therapy of ZGR, and maintenance therapy of ZR
EXPERIMENTALInduction therapy: All enrolled patients received the ZGR regimen (zanubrutinib, obinutuzumab, and lenalidomide) for Cycles 1-4. Tumor response was assessed after Cycle 4. Patients achieving complete response (CR) or partial response (PR) continued the same ZGR regimen for 2 additional cycles (Cycles 5-6). Maintenance therapy: After completing induction therapy, patients with sustained CR/PR initiated maintenance therapy with zanubrutinib plus lenalidomide (ZR) for 18 months (1.5 years) or until disease progression, intolerable toxicity, or trial withdrawal (whichever occurred first)
Interventions
All enrolled patients received: Zanubrutinib: 160 mg twice daily, orally, on Days 1-28; Obinutuzumab: 1000 mg, intravenous infusion: Days 1, 8, and 15 of Cycle 1,on Day 1 of Cycles 2-6; Lenalidomide: 25 mg once daily, orally, on Days 1-21 of each 28-day cycle.
Maintenance therapy consists of zanubrutinib plus lenalidomide: Zanubrutinib: 160 mg twice daily, orally, on Days 1-28.Lenalidomide: 25 mg every other day, orally, on Days 1-21 of each 28-day cycle
Eligibility Criteria
You may qualify if:
- Gender: No restrictions; age ≥18 years.
- Diagnosis: Histologically confirmed CD20-positive follicular lymphoma (FL), Grade 1, 2, or 3A, per 2016 WHO classification. All patients must provide sufficient archived or fresh tumor tissue samples for immunohistochemical (IHC) analysis.
- Disease Stage \& Treatment Need:
- Stage III or IV disease, or Stage II with bulky disease, meeting at least one of the following criteria:
- a) Bulky disease: Lymph node or extranodal (excluding spleen) mass with maximum diameter ≥7 cm.
- b) Local symptoms or organ dysfunction due to progressive lymphadenopathy or extranodal tumor mass.
- c) B symptoms (fever, night sweats, or unintentional weight loss \>10% of body weight within ≤6 months).
- d) Symptomatic extranodal involvement (e.g., pleural/peritoneal effusion).
- e) Cytopenias due to bone marrow infiltration (hemoglobin \<10 g/dL, absolute neutrophil count \[ANC\] \<1.0×10⁹/L, platelets \<100×10⁹/L).
- f) Involvement of ≥3 lymph nodes, each ≥3 cm in diameter.
- g) Symptomatic splenomegaly.
- Prior Therapy: No prior systemic therapy for FL.
- ECOG Performance Status: ≤2.
- Measurable Disease: At least one measurable lesion (\>2 cm in longest diameter by CT/MRI).
- Life Expectancy: ≥6 months.
- +8 more criteria
You may not qualify if:
- Patients meeting any of the following criteria will be excluded from this study:
- Histologic evidence of central nervous system (CNS) lymphoma, leptomeningeal lymphoma, or transformation to high-grade lymphoma (e.g., diffuse large B-cell lymphoma, DLBCL).
- Grade 3B follicular lymphoma (FL) or transformed FL.
- Ann Arbor Stage I FL.
- Prior history of malignancy, unless the patient has been disease-free for ≥5 years and the treating physician deems the risk of recurrence low (exceptions: non-melanoma skin cancer, cured localized prostate cancer, carcinoma in situ of the cervix, or squamous intraepithelial lesions on PAP smear).
- Use of any investigational drugs, antibiotics, or participation in another interventional clinical trial within 4 weeks prior to enrollment.
- Major surgery (excluding lymph node biopsy) within 14 days before enrollment or anticipated need for major surgery during the study.
- Prior treatment with zanubrutinib, obinutuzumab, or lenalidomide.
- Immunodeficiency or autoimmune disease history, or chronic systemic steroid therapy (\>10 mg/day prednisone equivalent) or immunosuppressive therapy within 7 days before enrollment.
- Severe hepatic dysfunction (including severe jaundice, hepatic encephalopathy, refractory ascites, or hepatorenal syndrome), cachexia, or multi-organ failure with renal impairment.
- Clinically significant cardiovascular abnormalities:
- NYHA Class III/IV heart failure
- Myocardial infarction within 6 months before enrollment, Malignant arrhythmias (including QTc ≥480 ms), Uncontrolled hypertension (Systolic blood pressure (SBP) ≥150 mmHg and diastolic blood pressure (DBP) ≥100 mmHg), Unstable angina.
- Active infections:
- HIV, active hepatitis B/C infection (HBV DNA ≥2000 IU/mL or HCV RNA detectable)
- +5 more criteria
