NCT07198087
A study to investigate the pharmacokinetics of tirabrutinib in participants with mild, moderate, and severe hepatic impairment compared to healthy participants
NCT07523737
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.
NCT03703167
The investigator's want to find out if treatment with ibrutinib, rituximab, and lenalidomide are safe and better than the usual approach in patients with recurrent or refractory central nervous system lymphoma.
NCT07074470
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.
NCT04688151
To evaluate the safety and tolerability and determine the recommended phase 2/phase 3 dose of RAD regimen in PCNSL
NCT06714370
The goal of this observational study is to describe the real-world effectiveness and safety of tirabrutinib among relapsed or refractory PCNSL patients in Taiwan.
NCT04253496
We plan to analyze 100 PCNSL homogenously treated with high-dose methotrexate based chemotherapy using NGS of PCNSL samples. We will perform DNA-seq and RNA-seq from tumor samples. This data will be combined with their magnetic resonance imaging (MRI) at different time points: at diagnosis, at the end of the treatment and at disease progression. Among the 100 PCNSL that will be included, 70 will be from a retrospective (training set) from patients included in the French National PCNSL dataset (LOC cohort) and 30 PCNSL from a prospective cohort from patients included in a phase III clinical trial (BLOCAGE, PHRC 2014). On the one hand, we will perform a radiomics analysis (quantitative imaging) using 3D tumor and edema segmentation. This analysis will help us to elucidate the potential correlation of MRI phenotypes and genotype (using high-throughput data). In addition, we will use the radiomics data combined with in vitro and in vivo data (using a mouse model of PCNSL) as well as immunohistochemistry data to obtain a multidimensional mathematical modeling of PCNSL clinical evolution that will allow us to better predict the clinical course of this rare subtype of brain tumor.
NCT00710151
This research is being done to investigate cognition in long term survivors of Primary Central Nervous System Lymphoma (PCNSL). Sometimes caregivers as well as patients who no longer have the disease report cognitive problems such as reduced memory or attentional dysfunction and decreased quality of life. Unfortunately, little is known about what may contribute to this cognitive dysfunction in part because PCNSL is a rare disease and sensitive tests have not often been used in the research studies. This project is being conducted to help understand what factors, such as radiation, may contribute to cognitive dysfunction and better define the relationship between brain structure and thinking in people who have had PCNSL.
