Inclusion criteria: Each patient eligible to participate in this study must meet all of the following criteria: -= 18 years of age at the time of informed consent -Histologically confirmed diagnosis of B-cell follicular lymphoma (grade 1, 2 or 3a) based on the WHO 2008 classification of tumors of hematopoietic and lymphoid tissue -= 2 prior systemic treatments for follicular lymphoma -Previously received an anti-CD20 antibody and an appropriate alkylator-based combination therapy (such as rituximab, cyclophosphamide, doxorubicin, and prednisolone; rituximab, cyclophosphamide, vincristine, and prednisolone; or bendamustine plus rituximab) -Disease progression within 12 months after completion of most recent therapy or refractory disease, defined as failure to achieve CR or PR to most recent therapy, and most recent therapy was an appropriate second-line (or later) systemic therapy for follicular lymphoma -Presence of measurable disease, defined as = 1 nodal lesion that is > 2 cm in longest diameter, or = 1 extranodal lesion that is > 1 cm in longest diameter -Availability of archival tissue confirming diagnosis of B-cell follicular lymphoma (or if archival tissue is not available, a copy of the pathology report confirming diagnosis of B-cell follicular lymphoma is required) -Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2 -Life expectancy = 6 months -Adequate organ function defined as: a. Absolute neutrophil count (ANC) > 750/mm3 (without growth factor support within 7 days) b. Platelet > 50,000/mm3 (without growth factor support or transfusion within 7 days) c. Creatinine clearance = 30 ml/min (as estimated by the Cockcroft-Gault or MDRD equation or as measured by nuclear medicine scan or 24-hour urine collection) d. Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase, and alanine aminotransferase (ALT)/serum glutamic pyruvic transaminase = 3.0 × upper limit of normal (ULN) e. Serum total bilirubin < 2.0 × ULN (unless documented Gilbert’s syndrome) Female patients of childbearing potential must practice highly effective methods of contraception initiated prior to first dose of study drug, for the duration of the study, and for = 90 days after the last dose of zanubrutinib, or 18 months after the last dose of obinutuzumab, whichever is longer. Highly effective contraceptive methods include the following: a. Combined (estrogen and progestogen containing) hormonal contraception associated with the inhibition of ovulation i. Oral, intravaginal or transdermal b. Progestogen-only hormonal contraception associated with the inhibition of ovulation i. Oral, injectable, implantable c. An intrauterine device d. Intrauterine hormone-releasing system e. Bilateral tubal occlusion f. Vasectomized partner g. Sexual abstinence (defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatment, starting the day prior to first dose of study drug, for the duration of the study, and for = 90 days after the last dose of zanubrutinib, or 18 months after the last dose of obinutuzumab, whichever is longer). Total sexual abstinence should only be used as a contraceptive method if it is in line with the patients’ usual and preferred lifestyle. Periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods), declaration of abstinence for the duration of exposure to investigational medicinal product, and withdrawal are not acceptable methods of contraception.

Exclusion criteria
Exclusion criteria: Each patient eligible to participate in this study must NOT meet any of the following exclusion criteria: 1. Known central nervous system involvement by leukemia or lymphoma 2. Evidence of transformation from follicular lymphoma to DLBCL or other aggressive histology (such as large cells seen on biopsy or high PET avidity in a single node seen on PET scan) 3. Allogeneic hematopoietic stem cell transplantation within 12 months of study enrollment 4. Prior exposure to a BTK inhibitor 5. Prior malignancy within the past 5 years, except for curatively treated basal or squamous cell skin cancer, superficial bladder cancer, carcinoma in situ of the cervix or breast, or localized Gleason score 6 prostate cancer. 6.

Uncontrolled hypertension as indicated by a minimum of 2 consecutive blood pressure measurements showing systolic blood pressure > 170 mm Hg and diastolic blood pressure > 105 mm Hg at screening 7. History of severe bleeding disorder such as hemophilia A, hemophilia B, von Willebrand disease, or history of spontaneous bleeding requiring blood transfusion or other medical intervention 8. History of stroke or intracranial hemorrhage within 6 months before first dose of study drug 9. Severe or debilitating pulmonary disease 10.

Known infection with HIV, or serologic status reflecting active hepatitis B or C infection as follows: a. Presence of hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb). Patients with presence of HBcAb, but absence of HBsAg, are eligible if hepatitis B virus (HBV) DNA is undetectable (< 20 IU/mL), and if they are willing to undergo monthly monitoring for HBV reactivation. b. Presence of hepatitis C virus (HCV) antibody. Patients with presence of HCV antibody are eligible if HCV RNA is undetectable (<15 IU/mL). 14. Major surgery within 4 weeks of the first dose of study drug 15. Pregnant or lactating women 16. Vaccination with a live vaccine within 35 days prior to the first dose of study drug 17.

| Main Objective: To evaluate efficacy of zanubrutinib plus obinutuzumab versus obinutuzumab monotherapy, as measured by overall response rate determined by independent central review.;Secondary Objective: To evaluate efficacy of zanubrutinib plus obinutuzumab versus obinutuzumab monotherapy, as measured by the following: -Overall response rate determined by investigator assessment -Duration of response determined by independent central review and by investigator assessment -Progression-free survival determined by independent central review and by investigator assessment -Overall survival -Rate of complete response or complete metabolic response determined by independent central review and by investigator assessment -Time to response determined by independent central review and by investigator assessment -Patient-reported outcomes • Safety and tolerability • Pharmacokinetics (zanubrutinib plus obinutuzumab arm only);Primary end point(s): The primary endpoint is overall response rate determined by independent central review using Lugano Classification for Non-Hodgkin Lymphoma (NHL), (modified from Cheson et al, 2014). The overall response rate is defined as the proportion of patients who achieve either complete response or partial response as best overall response. Best overall response is defined as best response achieved during the entire follow-up period. However, for the patients in arm B who cross over to arm A, the disease assessment after the crossover will not be included in the derivation of best overall response.;Timepoint(s) of evaluation of this end point: Every 12 weeks for 24 months, then every 6 months for 24 months, then annually. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Overall response rate determined by investigator assessment • Duration of response determined by independent central review and by investigator assessment, defined as the time from the date that response criteria are first met to the date that disease progression is objectively documented or death, whichever occurs first • Progression-free survival determined by independent central review and by investigator assessment, defined as the time from randomization to the date of first documentation of disease progression or death, whichever occurs first • Overall survival defined as the time from randomization to the date of death due to any reason. • Rate of complete response or complete metabolic rate determined by independent central review and by investigator assessment, defined as the proportion of patients who achieve complete response or complete metabolic rate as best overall response • Time-to-response determined by independent central review and by investigator assessment, defined as the time from randomization to the time the response criteria are first met Patient-reported outcomes measured by EORTC QLQ-C30 and EQ-5D-5L questionnaires • Safety parameters, including AEs, SAEs, clinical laboratory tests, physical exams, and vital signs • PK parameters such as apparent clearance of the drug from plasma (CL/F) and AUC0-12;Timepoint(s) of evaluation of this end point: Every 12 weeks for 24 months, then every 6 months for 24 months, then annually. | — |
