Intravitreal MTX and ZR Regimen in Newly Diagnosed PVRL
- Conditions
- Primary Vitreoretinal Lymphoma
- Interventions
- Registration Number
- NCT04899453
- Lead Sponsor
- Peking Union Medical College Hospital
- Brief Summary
This is a prospective single-arm phase II study, and the purpose of this study is to evaluate the efficiency of ZR regimen (rituximab \& Zanubrutinib) combined with intravitreal methotrexate and followed by Zanubrutinib maintenance in newly-diagnosed primary intraocular lymphoma. Progression-free survival (PFS) of the cohort is the primary endpoint.
- Detailed Description
All the patients will be treated with ZR regimen (Rituximab 375mg/m2 IV d1, Zanubrutinib 160mg Bid, 21 days per cycle) as induction regimen, meanwhile intravitreal methotrexate was given at a dose of 400ug for 16 doses. The response will be evaluated every 3 cycles. After 3 Cycles, patients who achieved complete remission (CR) or partial remission (PR) will receive 3 more cycles of ZR regimen. The patients with stable disease (SD) or progressed disease (PD) will withdraw from the trial and receive salvage regimens. After total 6 induction cycles, the investigators evaluate the efficiency again, the patients with CR or PR will go to Zanubrutinib maintenance for 2 years or until progression of the disease (PD), unacceptable toxicity, or patient/investigator discretion. And the patients with SD or PD will receive a salvage regimen. During following-up, surveillance ophthalmologic examination, and brain magnetic resonance imaging (MRI) scans can be performed every 3 months up to the first 2 years, followed by the doctor visit every 6 months up to 5 years or the disease relapses.

Group Intervention Description Zanubrutinib/rituximab & intravitreal MTX Methotrexate Experimental arm will be treated with rituximab plus zanubrutinib (ZR) regimen for 6 cycles and followed by zanubrutinib maintenance for 2 years, meanwhile, intravitreal methotrexate will be given as protocol during the 1st year of treatment. Zanubrutinib/rituximab & intravitreal MTX Zanubrutinib Experimental arm will be treated with rituximab plus zanubrutinib (ZR) regimen for 6 cycles and followed by zanubrutinib maintenance for 2 years, meanwhile, intravitreal methotrexate will be given as protocol during the 1st year of treatment. Zanubrutinib/rituximab & intravitreal MTX Rituximab Experimental arm will be treated with rituximab plus zanubrutinib (ZR) regimen for 6 cycles and followed by zanubrutinib maintenance for 2 years, meanwhile, intravitreal methotrexate will be given as protocol during the 1st year of treatment.
- Primary Outcome Measures
Name Time Method 2 years progression-free survival from the date of treatment to the subject finished his 2 years follow-up phase or the disease relapsed or the death due to lymphoma 2 years progression-free survival was calculated from the date of therapy until death from lymphoma or 2-year follow up without relapsing
- Secondary Outcome Measures
Name Time Method overall response rate (ORR) 4 weeks after the end of 6 cycles of induction (each cycle is 21 days) ORR was calculated by the proportion of patients who achieved complete remission and partial remission
