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

To explore the safety, tolerability, and clinical effects of decitabine combined with Second-line chemotherapy regimens for patients with relapsed or refractory T-lymphoblastic lymphoma.

The purpose of this study is to evaluate the safety and efficiency of CD19-Targeted CAR-T in Treating Patients with relapsed/refractory acute leukemia.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) in early first complete remission improves the long-term outcomes for Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ ALL). Relapse remains a major cause of treatment failure even after allo-HSCT. The prevention of relapse is essential for improving the outcome of Ph+ ALL. Our previous clinical trial (ID: NCT01883219) demonstrated that pre-emptive tyrosine kinase inhibitor (TKIs) administration based on minimal residual disease (MRD) and BCR-ABL mutation after allo-HSCT might reduce the incidence of relapses and improve survival for patients with Ph+ ALL. Moreover, our result suggested that Ph+ ALL with MRD positive pre-transplants had the higher rate of molecular biology relapse. In this study, we will evaluate the safety and efficacy of prophylactic TKI therapy post-transplants on Ph+ ALL undergoing allo-HSCT with MRD positive pre-transplants.

This is a single arm, open-label, early phase I study, to determine the safety and efficacy of Novel CAR-T cell therapy in Hematological Malignancy treatment.

The study is an early, open, single-centered trial. The aim of this study is to evaluate the safety and tolerance of GC022F CAR-T cell immunotherapy in relapsed or refractory B-ALL. The study will include 18 subjects to receive GC022F therapy.

The main purpose of the project is to evaluate the disease free survival and overall survival in patients diagnosed with acute lymphoblastic leukemia undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) adding gemcitabine to the standard institutional conditioning regimen based on two alkylating drugs, reduced busulfan and cyclophosphamide (reduced BUCY 2).

For micro residual disease (MRD) positive patients who have undergone at least 2 cycles chemotherapies for their CD19+ B-cell malignancies, there would be much more risks for them to receive hematological stem cell transplantation (HSCT) than MRD- patients. In order to reduce HSCT-related adverse events for these kind of patients, investigators plan to conduct CAR-T therapies on them first to make them achieve MRD- statuses, and then transfer them to HSCT.

A phase II trial of continuous intravenous infusion of Blincyto given over a 28-day cycle. Starting day for patients who are MRD-positive before HSCT is between day +60 and day +100 and for patients who become MRD-positive post HSCT it is between day +60 and day +360 post HSCT. Patients will be evaluated for response at day +28 (+4 days) (bone marrow morphology and MRD analysis - defined by PCR/FLOW-techniques) after start of Blincyto-treatment at the end of first Blincyto infusion and at regular post-TX-checks (according to FORUM: days +28, +60, +100, +180 and +360 after HSCT). The dose of Blincyto used in this trial will be 15 mcg/m2/day for 28 days

Our previous study demonstrated that anti-CD19 chimeric antigen receptor in piggyBac transposon-engineered T cells have strong tumor-killing activity in vitro and therapeutic effects in cell line-derived xenograft models, and no obvious side effects such as neurotoxicity and cytokine storm occurred. Therefore, we want to evaluate the safety and clinical effect of anti-CD19 CAR-T cells in clinical trials.

Diagnosis: Acute myeloid leukemia; Acute lymphoblastic leukemia Age ≥ 18 years, no upper age limit Study drug: Palbociclib Phase Ib/IIa, open-label Phase Ib: Based on previous experience with 125 mg palbociclib once daily for 21 days followed by 7 days of rest in patients with breast cancer, liposarcoma, non-small cell lung cancer, hepatocellular carcinoma, ovarian cancer, mantle-cell lymphoma, and glioblastoma, this regimen will be chosen for the first dose to be evaluated in the phase Ib. Based on a 3 + 3 modified Fibonacci design, the tolerable dose of palbociclib for the phase IIa is defined. Phase IIa: single-agent palbociclib using the tolerable dose defined in the phase Ib part of the study is administered once daily for 21 days followed by 7 days of rest. Based on the optimal two-stage design of Simon, 21 patients are treated in the first stage. If results are positive, 29 additional patients will be recruited into the second stage of the study. An efficacy of the investigational therapy will be rejected in the first stage of 21 treated patients if two or less patients achieve complete remission (CR), CR with incomplete blood count recovery (CRi), partial remission (PR), or anti-leukemic effect (ALE). If three or more patients achieve CR, CRi, PR, or ALE during this first stage, the trial is intended to be continued in the second stage with a total sample size of 50 patients. Start of recruitment: July 2015 End of recruitment: July 2017 End of study (last patient out): July 2018 The treatment duration of an individual patient is estimated to be 2-6 months, but may be unlimited in patients with sustained response ("case-by-case decision"). Observation time per patient after entry into the study (incl. treatment) is at least 12 months.
