B-cell Lymphoma Refractory

Secondary involvement of the central nervous system (CNS), such as CNS relapse after treatment or progression during treatment, is a rare but deadly occurrence in patients with B-cell non-Hodgkin lymphoma (NHL), particularly in cases of diffuse large B-cell lymphoma (DLBCL) and transformed follicular lymphoma (FL). Despite the grim prognosis associated with secondary CNS involvement, no definitive treatment strategy exists. Selinexor®, an oral, first-in-class, potent selective inhibitor of nuclear export that binds to XPO1, leads to the nuclear retention of tumor suppressor and growth regulator proteins, as well as topoisomerase II enzymes, thereby restoring their functions. Preclinical studies have also shown that selinexor can sensitize cancer cells to topoisomerase inhibitors, alkylating agents, and steroids. Selinexor has been approved by the Food and Drug Administration for relapsed or refractory DLBCL. We hypothesize that selinexor could work synergistically with ifosfamide (an alkylating agent) and etoposide (a topoisomerase II inhibitor) in the ifosfamide, carboplatin, and etoposide (ICE) regimen. High-dose dexamethasone was added to this regimen to enhance the efficacy of ICE as a salvage regimen for secondary CNS involvement, due to its ability to cross the blood-brain barrier. This phase I/II study aims to evaluate the efficacy and safety of selinexor in combination with ifosfamide, carboplatin, etoposide (ICE), and dexamethasone in patients with relapsed or refractory B-cell non-Hodgkin lymphoma with secondary CNS involvement.

This is a single center, open label, phase 1 lead in to determine Recommended Phase 2 Dose (RP2D), followed by a phase 2 trial to evaluate the safety and efficacy of Epo-R-CD19 CAR T with or without CD22 CAR T-cells infused into patients with B cell lymphoma. The study will have the following parts: * Screening * Pre-infusion (cell product preparation and bridging) and infusion (lymphodepletion) * Primary efficacy endpoints * Long term follow up Patients who have high risk B cell lymphoma or relapsed/refractory B cell lymphoma who fufil the trial inclusion and exclusion criteria will undergo leukapheresis following trial enrollment. CAR T-cell products will then be manufactured according to the antigen expression on the patient's biopsied tumor cells. These cells will then undergo stringent testing before the patient undergoes lymphodepletion followed by CART infusion. These patients will be admitted for the infusion and closely monitored for any CRS or ICANS. This study will have a Phase 1 safety run in for the first 3-6 patients who receive the Epo-R-CD19 CAR T (with or without epoetin (erythropoietin)) to determine the tolerability and safety of this product. For the first 3-6 patients, if there are any DLT seen by Day 28, a data safety monitoring committee will be convened to assess the trial. Staggered dosing will be implemented for the first 2 participants in every dose level (DL1, DL2 and DL-1). For Phase 2, the RP2D will depend on DLT. If there is no DLT at DL+1 and DL+2, then the investigators will proceed with DL+2 as the RP2D dose. On the other hand, if there is DLT despite DL-1, then the study will be redesigned. Phase 2 will continue until a total of 20 patients received their CAR T-cell infusions. CAR-T monitoring will be performed at Day 0, 7, 14, 21, 28, month 2, 3, 4, 5, 6, 12 and yearly thereafter. The total duration of the study is 15 years from CAR T infusion.

The purpose of this study is to determine the efficacy and safety of the CAR-T cell immunotherapy utilizing polymer-lipid nanoparticles for delivering CD19/CD20 dual-targeting InViVoCAR1920 mRNA, for the first-line consolidation therapy of relapsed/refractory B-cell lymphoma/leukemia.

This is a phase l, single arm, prospective open, dose-escalation study in patients with relapsed or refractory CD19-positive B cell malignancies (ALL, NHL, CLL). The trial will include adult and pediatric patients. There will be three individual cohorts, defined by disease biology: pediatric ALL and aggressive pediatric NHL (Cohort 1), adult ALL (Cohort 2) and adult NHL/CLL (Cohort 3).

This study examines the safety, tolerability and preliminary efficacy of anti-CD19 /CD22 CAR T cells (KQ-2002)manufactured on-site in adults with relapsed or refractory CD19+ B cell acute lymphoblastic leukemia or CD19+ B cell non Hodgkin lymphoma.

This study was a single-arm trial of autologous NK cell adjuvant therapy for relapsed/refractory non-Hodgkin's B-cell lymphoma. The locations isXiangyang No.1 People's Hospital, Hubei University of Medicine. The population was relapsed/refractory non-Hodgkin's B-cell lymphoma. The sample size was 33. The intervention was R-GemOx regimen combined with autologous NK cells. The dose of autologous NK cells was body surface area x (2-4) x 109 cells. The course of treatment was once every 14 days. The primary outcome measure was ORR. The duration of assessment was for each treatment cycle, 1 month, 3 months, 6 months, 9 months, 12 months, 18 months, 24 months, 3 years, and 5 years of treatment.
