Sequential Treatment With RO-MTX After Pomalidomide, Orelabrutinib, Rituximab (POR) in Newly-diagnosed PCNSL

Study Purpose

This is a multicenter prospective single arm phase II study, and the purpose of this study is to evaluate the safety and efficacy of sequential treatment regimens with RO-MTX after pomalidomide, orelabrutinib, rituximab (POR) in newly-diagnosed primary central nervous system lymphoma, and explore the feasibility of chemo-free treatment in PCNSL. The primary objective was the overall response rate (ORR; defined as partial response [PR] or better) after 4 cycles of POR.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years - 70 Years
Gender	All

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05390749
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 2
Lead Sponsor The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.	Peking Union Medical College Hospital

Additional Details

There are 2 sections of this trial. Step1: the patients will be treated with 4 cycles of POR regimen （Pomalidomide 4mg d1-d14, Orelabrutinib 150mg d1-d21, Rituximab 375mg/m2 d1, 21 days per cycle). The response will be evaluated every 2 cycles. The patients with PD will drop out of the study. Step2: Patients with CR/PR/SD after 4 cycles of POR treatment will be treated with 2 cycles of RO-MTX regimen（methotrexate 3.5g/m2 civ d1, Orelabrutinib 150mg d1-d21, Rituximab 375mg/m2 d1, 21 days per cycle). After 6 cycles of induction therapy, all patients were followed for survival data every 12 week until disease progression, disease recurrence, death, or study termination. Patients with progression were also followed up for survival data as above. Overall survival will be followed up to 3 years after the last subject entered the study. Establishing the feasibility of chemo-free treatment in primary central nervous system lymphoma will provide the foundation for a larger study of efficacy and long-term outcomes of chemo-free therapy for patients with PCNSL.
