Active clinical trials for "Precursor T-Cell Lymphoblastic Leukemia-Lymphoma"

This is a single dose escalation study to evaluate the safety and clinical activity of ThisCART7(Allogeneic CAR-T targeting CD7) in patients with refractory or relapsed CD7 positive T cell malignancies.

This is a phase 1, dose-escalation study (using 3 + 3 dose-limiting toxicity (DLT) criteria) evaluating the safety and tolerability of XmAb18968, as well as establishing a recommended phase II dose (RP2D) in subjects with T cell acute lymphoblastic leukemia (T-ALL) and T cell lymphoblastic (lymphoma) T-LBL (Group A) and acute myeloid leukemia (AML) (Group B).

The purpose of this study is to evaluate the safety and efficacy of CAR T cell treatment targeting CD7 in patients with relapsed or refractory CD7 positive T-cell hematological maliganacies

This phase Ib/II trial studies the effects of tagraxofusp and low-intensity chemotherapy in treating patients with CD123 positive acute lymphoblastic leukemia or lymphoblastic lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Tagraxofusp consists of human interleukin 3 (IL3) linked to a toxic agent called DT388. IL3 attaches to IL3 receptor positive cancer cells in a targeted way and delivers DT388 to kill them. Chemotherapy drugs, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving tagraxofusp with chemotherapy may help control CD123 positive relapsed or refractory acute lymphoblastic leukemia or lymphoblastic lymphoma.

This is a phase I, interventional, single arm, open label, treatment study to evaluate the safety and tolerability of CD7 CAR-T cells in patients with relapsed and/or refractory, high risk hematologic malignancies.

The purpose of this study is to evaluate the efficacy and safety of decitabine combined with HAAG regimen in the treatment of newly diagnosed patients with ETP-ALL/LBL, T/M-MPAL and ALL/LBL with myeloid or stem cell markers.

T cell acute lymphoblastic leukemia (T-ALL)/Lymphoblastic lymphoma (LBL) is a hematological malignancy caused by malignant transformation and clonal expansion of T-lineage precursor cells. The long-term cure rate of pediatric patients with T-ALL/LBL reaches 90%, but long-term survival of adult patients is less than 60%. Moreover, patients with high-risk factors such as PTEN/NRAS gene mutation, early T cell precursor (ETP) phenotype or positive minimal residual disease (MRD) have high rates of chemoresistance and dismal outcome. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) can significantly improve the prognosis of high-risk T-ALL/LBL. Total body irradiation (TBI)-based conditioning chemotherapy regimen is the preferred regimen for allo-HSCT in children and young adults with ALL because of lower relapse rates and satisfactory survival. Different from children, the non-relapse-related mortality (NRM) after TBI-based preconditioning in adults (especially those >35 years old) was reported as high as 38%. In addition, serious sequelae after TBI seriously affect the quality of life and non-radiation conditioning chemotherapy regimens are urgently needed for T-ALL/LBL. The reported recurrence rates after BUCY (busulfan + cyclophosphamide) conditioning regimen for T-ALL as 41.2%. -56.7% and long-term survival was only 30-50%. Thiotepa is an ethyleneimine alkylating agent with anti-tumor effects and immunosuppressive effects, thus is widely used in conditioning regimen before HSCT. Retrospective paired analysis from EBMT indicated conditioning regimen thiotepa achieved similar relapse rates, long-term survival and faster granulocyte and platelet engraftment than TBI regimen. A recent retrospective study of childhood ALL from Turkey also reported that the TBF(thiotepa + fludarabine + busulfan) regimen had a recurrence rate of only 11.9% , a non-relapse mortality rate of 14.0% and a long-term survival of 79.1%. Data from a large retrospective paired study suggested TBF regimen can significantly reduce the relapse rate of acute myeloid leukemia after the first remission (HR=0.4, CI 0.2-0.7, P = .02) without increasing treatment related deaths compared with the traditional BUCY regimen. Based on these data, we modified the TBF regimen with additional cytarabine for allo-HSCT in T-ALL/LBL with expection to reduced disease relapse and improved long-term survival.

This is a Phase 1/2, multicenter, open-label study to evaluate the safety and efficacy of BEAM-201 in patients with relapsed/refractory T-ALL or T-LL. This study consists of Phase 1 dose-exploration cohorts, Phase 1 dose-expansion cohort(s), a Phase 1 pediatric cohort (will enroll patients ages 1 to < 12 years), and a Phase 2 cohort.

This is a FIH, single center, open label, non-randomized, single-arm, Phase I clinical trial to evaluate the safety and tolerability of CD5 CAR T (CT125B) cells in subjects with relapsed or refractory T-cell acute lymphoblastic leukemia/lymphoma. 9-18 subjects will be enrolled. After the collection of PBMC and about 5 days before infusion, lymphodepletion (fludarabine at 30 mg/m^2/day and cyclophosphamide at 250 mg/m^2/day; for prior-SCT donor-derived CAR T-cell infusion) or intensified lymphodepletion (fludarabine at 30 mg/m^2/day and cyclophosphamide at 30 mg/kg/day; for new donor-derived CAR T-cell infusion) will be administrated for 3 days. Then this study will be using BOIN1/2 approach from starting dose 1: 1×10^6 (±20%) to dose 2: 2×10^6 (±20%). If the manufactured cells were not sufficient to meet the preassigned standard dose criteria, patients are given infusion at a low dose of 5×10^5 (±20%) /kg.

The purpose of this study is to evaluate the efficacy and safety of venetoclax combined with azacitidine regimen for newly diagnosed T-ALL patients.
