Primary Central Nervous System Lymphoma (PCNSL)

This project aims to establish and prospectively register a longitudinal, multimodal biobank for primary central nervous system lymphoma (PCNSL). The study will primarily enroll patients undergoing needle biopsy or surgical resection of lesions involving the brain, spinal cord, or meninges, with a pathological diagnosis of central nervous system lymphoma. To ensure population homogeneity, patients with PCNSL will constitute the core analysis cohort. Patients with imaging findings suggestive of PCNSL but a final pathological diagnosis other than PCNSL will serve as disease controls, and matched healthy volunteers will be recruited as baseline controls. At baseline, biopsy tissue, cerebrospinal fluid (CSF), peripheral blood, urine, saliva, and stool samples will be collected. Follow-up visits will be scheduled at 1 month after biopsy and every 3-6 months thereafter, with contrast-enhanced brain magnetic resonance imaging (MRI) and serial collection of CSF and peripheral blood. After the requirements of routine pathological diagnosis have been met, biopsy specimens will undergo tiered multi-omics profiling according to sample availability and freshness, including whole-exome sequencing, bulk RNA sequencing, single-cell RNA sequencing, metabolomics, spatial transcriptomics, and spatial metabolomics. Analyses of CSF and blood samples will focus on circulating tumor DNA and cell-free RNA (ctDNA/cfRNA), supplemented by conventional cytology, flow cytometry, and other clinical data for longitudinal disease monitoring. The project will develop an integrated database incorporating clinical, imaging, pathological, molecular, and biospecimen data. It will characterize the relationships of baseline tissue multi-omics features and longitudinal changes in CSF- and blood-derived ctDNA/cfRNA with treatment response, recurrence prediction, and prognosis. The study will also develop diagnostic and risk-stratification models applicable to patients at our institution, across the region, and potentially throughout mainland China, while establishing standardized operating procedures for biospecimen collection and processing. This work is expected to provide high-quality evidence and a sustainable translational research platform for elucidating the biological heterogeneity of PCNSL, validating liquid-biopsy biomarkers, and optimizing precision follow-up strategies.

This is a prospective, single-arm, phase II clinical study evaluating the efficacy and safety of Zanubrutinib (a BTK inhibitor) plus Lenalidomide (an immunomodulatory drug) in frail elderly patients with newly diagnosed primary central nervous system lymphoma (PCNSL). The study plans to enroll 33 patients who are aged ≥ 70 years and classified as frail, a population for whom standard first-line treatment regimens, high-dose methotrexate-based chemotherapy, may be "unfit". This study includes screening phase, induction phase, consolidation phase and maintenance phase. The screening period is defined as within 1 week prior to the first dose. During induction, participants will receive Zanubrutinib 160 mg orally twice daily continuously and Lenalidomide 25 mg orally once daily on days 1-21 of each 28-day cycle for three cycles. Participants who achieve a partial response (PR) or complete response (CR) after induction will receive three additional 28-day consolidation cycles of the same regimen. Participants who achieve a CR after consolidation will continue maintenance treatment with Zanubrutinib and Lenalidomide until disease progression. Treatment response will be assessed throughout the study using the International Primary CNS Lymphoma Collaborative Group (IPCG) criteria and assessed every 3 months. The primary endpoint is the complete response rate (CRR) at the end of induction therapy. Secondary endpoints include overall response rate (ORR) at the end of induction therapy, CRR and ORR at the end of consolidation therapy, One-year and two-year progression-free survival (PFS) rates, Duration of response (DOR), overall survival (OS), adverse event (AE) and serious adverse event (SAE). Exploratory liquid-biopsy analyses will be performed to evaluate treatment response and prognosis.

The purpose of this study is to find out whether the combination of epcoritamab and ibrutinib is a safe treatment approach that causes few or mild side effects in people with relapsed/refractory primary central nervous system lymphoma (PCNSL) or secondary central nervous system lymphoma (SCNSL).

This is a first-in-human Phase 1a/1b multicenter, open-label study designed to evaluate the safety and anti-cancer activity of NX-5948 in patients with advanced B-cell malignancies.

Primary central nervous system diffuse large B-cell lymphoma (PCNSL-DLBCL) is a highly aggressive malignancy accounting for over 80% of primary CNS lymphomas, with an annual incidence of 0.4-0.6 per 100,000 people globally and a rising trend in immunocompetent patients. First-line high-dose methotrexate-based chemotherapy causes severe toxicities and nearly 50% of patients relapse within 1-2 years, developing relapsed/refractory (R/R) disease. Treatment options for R/R PCNSL are scarce, with low response rates, median survival of only 3-6 months, and 5-year survival below 5%. The blood-brain barrier and tumor heterogeneity further worsen outcomes. This prospective, multicenter, single-arm phase II study evaluates the efficacy and safety of pomalidomide, PD-1 inhibitor, and selinexor (PPS) in R/R PCNSL, aiming to provide a new effective treatment.

This is a first-in-human Phase 1a/1b multicenter, open-label oncology study designed to evaluate the safety and anti-cancer activity of NX-2127 in patients with advanced B-cell malignancies.

This is a multicenter, open-label, single-arm, prospective clinical study of PD-1 inhibitor combined with rituximab, methotrexate, and orelabrutinib (PD-1i+RMO) in the treatment of newly diagnosed primary central nervous system lymphoma (ND-PCNSL) and secondary central nervous system lymphoma (SCNSL). The primary endpoint is 1-year progression-free survival (PFS).

This study is a prospective cohort study. The case group will include patients with primary central nervous system lymphoma confirmed by imaging and pathology. The control group will include patients with pathologically confirmed diffuse large B-cell lymphoma who have been excluded from central nervous system involvement, as well as age- and gender-matched healthy volunteers (hematopoietic stem cell donors). Baseline data (as described below) will be collected. Patients with primary CNS lymphoma will undergo follow-up every 3 months, with immediate follow-up if clinical symptoms arise.

To evaluate the efficacy and safety of relmacabtagene autoleucel combined with autologous hematopoietic stem cell transplantation, orelabrutinib, and sintilimab as first-line or relapsed/refractory treatment for primary central nervous system diffuse large B-cell lymphoma.

This study aims to evaluate the efficacy and safety of the VPX regimen, a novel combination of teniposide, PD-1 monoclonal antibody and selinexor, in patients with relapsed/refractory (R/R) primary central nervous system lymphoma (PCNSL) who have progressed after high-dose methotrexate (HD-MTX)-based systemic therapy. By investigating this therapeutic approach, we seek to establish a new treatment paradigm that may improve clinical outcomes of this high-risk population.

The goal of this single-arm, prospective study is to learn if high dose gemcitabine, busulfan and thiotepa with autologous stem cell transplantation to treat primary or relapse central nervous system lymphomas. It will learn about the safety and efficacy of combination therapy. The main question it aims to answer is: Efficacy and safety of the combination of high dose gemcitabine, busulfan and thiotepa as a bridging therapy to ASCT in patients with CNSL. Participants will: Take gemcitabine (2.5 g/m²) was administered intravenously (IV) on Days -9 and -3, Busulfan (3.2 mg/kg) was given IV over 3 hours on Days -9 to -7, and thiotepa (5 mg/kg) was administered IV on Days -5, -4, and -3. Peripheral stem cells were infused on Day 0. Visit the clinic for checkups and tests in accordance with the International Primary CNS Lymphoma Group (IPCG). Researchers will observe the patients receiving GemBuTT regimen as conditioning therapy in CNSL.

High-dose methotrexate (HD-MTX) remains the foundation of treatment for primary central nervous system lymphoma (PCNSL), but outcomes are suboptimal. The addition of rituximab has shown mixed results, partly due to limited blood-brain barrier penetration. The MATRix regimen (rituximab, HD-MTX, cytarabine, thiotepa) has improved survival but is associated with significant toxicity. Consolidation therapy is recommended after induction, but there is no standard approach. Preliminary data suggest that etoposide and cytarabine (EA) consolidation after rituximab-HD-MTX induction may offer improved tolerability, though relapse rates remain high. This study evaluates the safety, efficacy, and tolerability of a novel RMT-EA regimen-rituximab, methotrexate, and thiotepa (RMT) induction followed by etoposide and cytarabine (EA) consolidation-in newly diagnosed, untreated PCNSL patients. The aim is to improve remission depth and prolong disease-free survival, especially in younger patients.

This is a phase Ⅱ clinical study of Zanubrutinib(Z) in combination with methotrexate (M) and thiotepa(T) in treating newly diagnosed primary CNS lymphoma (PCNSL). The purpose of the study is to test the efficacy and tolerability of a combination treatment of MTZ regimen in treating patients who have newly diagnosed PCNSL
