NCT06931652
The purpose of this phase 2 study is to evaluate the efficacy and safety of epcoritamab in subjects with relapsed or refractory primary diffuse large B-cell lymphoma of the Central Nervous System treated with rituximab and lenalidomide.
NCT05098613
This open-label, single arm phase 1 trial aims to determine the safety and tolerability of anti-CD19 and anti-CD22 chimeric antigen receptor-expressing (CAR) T cells (CD19x22 CAR T) in adolescents and adults with relapsed/refractory (R/R) B-cell Non-Hodgkin Lymphoma (B-NHL). This trial will determine the maximum tolerated dose of CD19x22 CAR T cells using a standard 3+3 trial design.
NCT04464200
The purpose of this study is to test the safety of 19(T2)28z1xx CAR T cells in people with relapsed/refractory B-cell cancers. The researchers will try to find the highest dose of 19(T2)28z1xx CAR T cells that causes few or mild side effects in participants. Once they find this dose, they can test it in future participants to see if it is effective in treating their relapsed/refractory B-cell cell cancers. This study will also look at whether 19(T2)28z1xx CAR T cells work against participants' cancer.
NCT05036564
Thi is a prospective and low-intervention clinical trial. We propose to design a panel of "core" genetic alterations by sequencing Cerebral Spinal Fluid (CSF) DNA in patients with confirmed or suspicious Primary Central Neurvous System Lymphoma (PCNSL) with the aim to improve diagnostic sensitivity, response assessment and monitoring early CNS relapse in routine practice. Enrolled patients will receive conventional treatments according to well-established international guidelines, DNA assessments will not influence the treatment choices.
NCT06901999
This study is designed as an open-label, prospective, single-arm, single-center trial aimed at evaluating the efficacy and safety of MTX or Thiotepa combined with Orelabrutinib and standard chemotherapy regimens in the treatment of DLBCL patients with central nervous system involvement.
NCT05351593
This is a single arm open-label multicenter phase I/II investigation of combination lenalidomide/Tafasitamab in patients with relapsed central nervous system (CNS) lymphoma. This is the first study to examine a naked anti-CD19 monoclonal antibody in relapsed CNS lymphoma patients as well as the combination of anti-CD19 antibody plus an Immunomodulatory imide drugs (IMiDs) in CNS lymphomas. This study will also test the novel hypothesis that Tafasitamab enhances blood-brain barrier permeability, a potential property that could have broad clinical implications.
NCT04841434
This phase I-II trial is intented to demonstrate tolerability (i.e. absence of severe non-hematological toxicity) and efficacy of intended intervention with repeated doses of Voraxaze, in addition to leucovorin (LV), in patients with renal impairment or renal failure during previous HD-MTX therapy. Patients will receive up to 6 cycles of HD-MTX treatment with 14 days between cycles (a maximum delay of 28 days is permitted in order to allow time for a patient to recover from the previous cycle).
NCT00596154
The purpose of this study is to determine the safety of this new treatment offered in this study. PCNSL can be cured in less than half of patients with standard treatment, a combination of chemotherapy and brain radiation. Also, the combination of chemotherapy and brain radiation may result in serious lasting side effects. Most patients older than age 60 develop memory problems, difficulty walking or inability to control their bladder. Some patients younger than age 60 also develop these side effects.

NCT04006561
Primary central nervous system lymphoma (PCNSL) is an uncommon disease. Conventional treatment has consisted of either whole-brain radiation therapy (WBRT) or methotrexate (MTX)-based combined modality therapy integrating chemotherapy with cranial irradiation in a sandwiched manner. No matter whether the dosage of MTX is high or conventional, combining chemotherapy with WBRT greatly improves intracranial tumor control and even survival outcomes. However, delayed treatment-related neurotoxicity and neurocognitive sequelae emerged as a significant debilitating complication in PCNSL patients, especially when effective combined chemoradiation can achieve disease control and long-term survival rates. Therefore, by delivering hyperfractionated conformal WBRT plus SIB, this prospective cohort study aims to accomplish both optimal intracranial control and minimal WBRT induced neurocognitive decline. Additionally, by administering objective multi-domain neurobehavioral/neurocognitive assessments, the change in neurocognitive functions (NCFs) before and after the course of hyperfractionated conformal WBRT will be investigated and analyzed. According to the treatment guidelines for treating newly-diagnosed PCNSL patients, combined chemoradiation in which the WBRT course is sandwiched between initial courses of MTX and the later courses of chemotherapy with Ara-C is the treatment of mainstay at our institute. Employing the technique of a conformal CT treatment planning, the WBRT course is delivered in the manner of hyperfractionation with a reduced cumulative dose of 3600 cGy in 30 fractions during 3-4 weeks, administered twice daily in 1.2 Gy - fractions with at least 6 hours between fractions. By virtue of multidisciplinary management and teamwork including neurosurgery, hematology, radiation oncology, and neuroimaging expertise, it is attempted to recruit all potentially eligible patients with newly-diagnosed PCNSL. Most importantly, a professional neuropsychologist participates in this research project to integrate neurobehavioral outcomes into the prospective study. Accordingly, a battery of neuropsychological measures is used to evaluate predetermined NCFs for the studied patients. The test battery is composed of six standardized neuropsychological tests, covering four domains sensitive to disease and treatment effects (executive function, attention, verbal memory, information processing). The primary outcome measure is the change in patients' capability of information processing indicated by the Paced Auditory Serial Addition Test-Revised (PASAT-R), from the baseline before receiving the WBRT course to the follow-up after undergoing the entire courses of combined chemoradiation. This prospective cohort study aims to thoroughly examine newly diagnosed PCNSL patients by using a standard battery of neurobehavioral/neurocognitive functions. Additionally, a better intracranial disease control is expected since the WBRT course relies on a highly conformal treatment planning integrated with the individualized arrangement of simultaneous integrated boost (SIB) to escalate the focal dose irradiating the originally involved site(s). Moreover, WBRT-related neurocognitive sequelae might be significantly less likely to occur because the WBRT course is delivered in the fashion of hyperfractionation, indicating a significantly lower dose per fraction and a reduced cumulative dose. Furthermore, it is anticipated the investigators will analyze which neurobehavioral domain would predict the treatment-related neurocognitive impacts to the largest extent in newly diagnosed PCNSL patients treated with cranial RT combined with or without MTX based chemotherapy according to the multidisciplinary treatment guidelines implemented at a single institute.
NCT01182415
Current standard treatments for lymphoma involving the central nervous system include chemotherapy or whole brain radiation therapy (WBRT). However, many patients do not respond to this treatment, and some of the patients who do respond relapse after treatment. Previous research has shown that a stem cell transplant of a patient's own cells (autologous stem cell transplant) may be more effective for some patients with lymphoma involving the CNS. In previous research using autologous stem cell transplants for lymphoma involving the CNS, a conditioning regimen consisting of the drugs thiotepa, busulfan and cyclophosphamide (TCE) was used. These drugs have been shown to enter the nervous system. In this research study, the investigators are adding the drug rituximab (Rituxan) to the drug cytarabine for the stem cell mobilization process. Cytarabine is a standard drug for mobilization. In addition, rituximab will be added to the conditioning regimen of thiotepa, busulfan and cyclophosphamide. Rituximab is approved by the FDA for the treatment of some types of lymphomas, but is not approved for use in lymphomas that involve the CNS. Rituximab is known to be able to enter the CNS. Previous research has suggested that it may help treat lymphoma that involves the CNS. The goal of this research study is to see if adding rituximab to the stem cell mobilization and conditioning regimens helps treat lymphoma that involves the central nervous system.

Zanubrutinib is a novel BTK inhibitor with proven activity in patients with various B-cell lymphomas addicted to the B-cell receptor signaling pathway.
NCT05293990
Polyplastic glioblastoma and metastatic brain cancer are the most common malignant brain tumors in adults. The primary diagnostic test for tumors in the brain shows magnetic resonance imaging or similar imaging findings (especially single metastatic brain cancer) that make it difficult to distinguish between these two diseases. In addition, due to the specificity of the tissue called the brain, biopsy is not easy and sometimes biopsy is difficult, so non-invasive discrimination is often important, and it is important how much prediction is made before the biopsy. To solve this problem, various advanced magnetic resonance imaging techniques have been studied, but they are all tests that need to be additionally conducted on ordinary magnetic resonance images, and there are many subjective factors, so complex data and statistical processing methods, and many cannot be easily tested. In addition, in all of these tests, accuracy is still reported at around 60%. Therefore, if contrast-enhanced FLAIR images can be obtained along with contrast-enhanced T1 images performed during conventional magnetic resonance imaging tests to help differentiate between two diseases, it will greatly help diagnose and treat brain tumor patients and facilitate clinical application.
