Diffuse Large B Cell Lymphoma | Drug: Zanubrutinib, Polatuzumab vedotin and Rituximab | Phase 2 |
This is a prospective, single-arm, single-center clinical study. This clinical study aims to explore the efficacy and safety of the ZPR(Zanubrutinib, Polatuzumab vedotin and Rituximab)regimen in the treatment of patients with relapsed and refractory diffuse large B-cell lymphoma.
- Primary objective: use ORR to evaluate the effectiveness of ZPR in treating R/R DLBCL patients
- Secondary objective: Evaluate the safety of ZPR treatment for R/R DLBCL patients
- The subjects received 6 cycles of ZPR regimen, one cycle every 21 days. Then Zanubrutinib alone will continue to be used until Zanubrutinib has been used for 1 year or the disease progresses or the adverse effects, death, withdrawal of informed consent or study termination.
Zanubrutinib(Z)160 mg bid po Day 1-21; Polatuzumab vedotin(P)1.8 mg/kg ivgtt D1; Rituximab(R)375 mg/m2 ivgtt D1.

- ORR at the end of the 6th treatment cycle [ Time Frame: about six months from the start of ZPR ]the proportion of participants who have achieved complete or partial remission determined by the researcher.
- CRR at the end of the 6th treatment cycle [ Time Frame: about six months from the start of ZPR ]the proportion of subjects evaluated by researchers to obtain CR.
- Proportion of patients who have achieved 2-year PFS [ Time Frame: 2 years, from the start of treatment to the first recording of disease progression or death, based on the investigator's assessment of the first occurrence ]Defined as the proportion of participants with a time of ≥ 2 years from the start of treatment to the first recording of disease progression or death, based on the investigator's assessment of the first occurrence
- Safety evaluation [ Time Frame: between the first administration of the study drug and 30 days after discontinuation, or during the progression of the disease or the initiation of new anticancer treatment, whichever came first ]incidence and severity of adverse events (AE) and Serious adverse event (SAE) during the study

Ages Eligible for Study: | 18 Years to 80 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
Patients must meet all of the following inclusion criteria to be enrolled in this study:
- Patients with histopathologically confirmed DLBCL;
-
Relapsed or refractory disease, defined as
- Disease relapse occurred after reaching disease remission (including complete response [CR] and partial response [PR]) at the end of the last treatment
- Maintain stable disease (SD) or progressive disease (PD) at the end of the last treatment
- The age of patients ≥ 18 years old and ≤ 80 years old;
- The ECOG score was 0-2;
- Good organ function;
- Measurable lesions detected by radiological imaging were defined as the longest diameter of at least 1 lymph node lesion > 1.5 cm, or the longest diameter of at least 1 extranodal lesion > 1.0 cm, and at least 2 vertical diameters that could be accurately measured;
- Previously received ≥ 1 systemic therapy for lymphoma;
- Participants who relapse after autologous stem cell transplantation may be included, provided that the transplantation treatment has been more than 6 months from the screening;
- Fresh tumor biopsies or recent tumor tissue samples must be provided (within 2 years after study entry [signed informed consent]);
- Fertile women must agree to use efficient contraceptive measures throughout the study and at least 90 days after the last dose of study drug. The effective forms of birth control are defined as abstinence, hysterectomy, bilateral oophorectomy without menstrual bleeding for up to 6 months, intrauterine contraception, hormonal methods such as contraceptive injection, oral contraceptives; Fertile men must undergo sterilization vasectomy or use condoms, while their female partners use the above efficient contraceptive measures;
- Life expectancy ≥ 6 months;
- Sign written informed consent.
Exclusion Criteria:
Patients with any of the following conditions cannot be enrolled in this study:
- Patients with primary central nervous system lymphoma;
- Patients with previous exposure to BTK inhibitors;
- Accompanied by uncontrolled cardiovascular and cerebrovascular diseases, coagulation disorders, connective tissue diseases, serious infectious diseases, etc;
- Currently clinically significant active cardiovascular disease, such as uncontrolled arrhythmia, congestive heart failure, any grade 3 or 4 heart disease defined by the New York Heart Association functional classification, or history of myocardial infarction within 6 months after screening. The left ventricular ejection fraction measured by echocardiography was < 50%;
-
Abnormal laboratory indicators at screening (unless caused by lymphoma):
- ANC<1.5×10^9/l, PLT<80×10^9/l
- Coagulation function: INR greater than 1.5 times the upper limit of normal value; Pt and APTT were greater than 1.5 times the upper limit of normal
- Liver function: ALT or ast was 2 times higher than the upper limit of normal, AKP and bilirubin were 1.5 times higher than the upper limit of normal
- Renal function: creatinine was 1.5 times higher than the upper limit of normal, creatinine clearance rate was < 60 ml/min (estimated according to Cockcroft Gault formula)
