Filter by:This study is a single-arm, open-label, dose-escalating + dose-expansion clinical study, aiming to evaluate the safety and efficacy of targeting CD123 CAR-NK cell preparations in Relapsed/refractory acute myeloid leukemia (AML) or blastocytic plasmacytoid dendritic cell neoplasm (BPDCN). The pharmacokinetic characteristics of CAR-NK cell preparations for the treatment of patients with Relapsed/refractory acute myeloid leukemia or blastocytic plasmacytoid dendritic cell neoplasm were obtained and the recommended dose.
The investigators developed a protocol combining chemotherapy of cladribine, cytarabine and etoposide (CLAGE) as debulking treatment sequential with reduced intensity conditioning regimen Flu-Bu to treat patients with refractory acute myeloid leukemia (AML). In this study, the aim is to further evaluate the efficacy and feasibility of the protocol with modifications: 1) reduced dose of CLAGE; 2) Reduced intensity conditioning (RIC) regimen as fludarabine, busulfan and melphalan (MBF) or total marrow irradiation (TMI); 3) Venetoclax was added to the chemotherapy and conditioning regimen.
To evaluate the safety and efficacy of Venetoclax plus IM2 regimen for relapsed and refractory T lymphoblastic lymphoma/leukemia. Dosage of Venetoclax:100mg/d-400mg/d(dose adjustment when concomitant used with CYP3A inhibitor) for 1-28 days (at least 7 days); IM2 regimen: Ifosfamide 1-1.5g/m2/d for 5 days; Mitoxantrone 6-8g/m2/d for 3 days( or Liposome mitoxantrone 20mg/m2 d1 or Idarubicin 6-8mg/m2/d for 3 days) ;methotrexate 1-1.5g/m2/d for 1 day;
This study is a prospective, single-center, single-arm exploratory clinical study, aiming to complete the preliminary clinical observation of 12 children with relapsed/refractory acute myeloid leukemia treated with JK500 cell injection to evaluate the safety of clinical infusion and the initial efficacy of JK500 cell injection in the treatment of children with relapsed/refractory acute myeloid leukemia.
This is an open-label, multicenter, phase 1b study, which is designed to explore the safety, efficacy and PK of olverembatinib, a third-generation tyrosine kinase inhibitor (TKI) marketed in China, in combination with APG-2575 in treating R/R Ph+ALL children, and to preliminarily establish the recommended dose of olverembatinib and APG-2575 for children based on the above results.
The purpose of this research is to investigate whether the combination of STING-dependent Adjuvants (STAVs) and dendritic cell (DC) vaccine therapies will increase the body's ability to fight aggressive relapsed or refractory leukemias.
The purpose of this study is to evaluate the safety and efficacy of Venetoclax Combining Chidamide and Azacitidine (VCA) in the Treatment of relapsed and/or refractory AML
CD19 CAR-T has been widely developed in patients with R/R ALL and has also been generally recognized by the industry. In 2017, the U.S. FDA approved Novartis's CD 19 CAR-T product Kymriah for the treatment of R/R ALL. However, these CAR-T cells are constructed from patients' autologous T cells, and the production and preparation time is long; on the other hand, most patients have received multiple chemotherapy before CAR-T treatment, and the quantity and quality of T cells often cannot meet the needs of clinical treatment. It is also an important factor leading to the failure of CAR-T cell therapy, which limits the large-scale clinical application of CAR-T. T cells derived from healthy donors are not only sufficient in quantity and quality guaranteed, but also available at any time. In December 2020, lancet reported a clinical study of 19 patients receiving allogeneic CAR-T cell ALL. 14 patients were evaluated as CR/CRi (67%) 28 days after treatment, and the median sustained remission time was 4.1 moon. Allogeneic CAR-T cells are safe and effective for the treatment of ALL, and their clinical application range is expected to improve the remission rate and survival rate of patients with R/R ALL.
During the last decades hematologists have excelled at improving and refining the classification, diagnosis, and thus ultimately the therapeutic decision-making process for their patients. This continuous evolution proceeded in parallel to seminal discoveries in basic science such as FISH, PCR and NGS. So far, the current WHO classification serves as reference to diagnostic decision making and is largely based on 5 diagnostic pillars: cytomorphology of peripheral blood and/or bone marrow smears, histology and immunohistochemistry of bone marrow trephine biopsies or lymph nodes, immunophenotyping, chromosome banding analysis supplemented by FISH analysis, molecular genetics including PCR and targeted panel sequencing via NGS. This leads to a swift diagnosis in 90 % of all cases. The leftover 10 % remain a challenge for hematopathologists and clinicians alike and are resolved through interdisciplinary teams in the context of specialized boards. With the advent of high throughput sequencing (mainly WGS and WTS) the possibility of a comprehensive and detailed portrait of the genetic alterations - specifically in challenging cases - has become a realistic alternative to classical methods. In SIRIUS the investigators will prospectively challenge this hypothesis to address the question of how often a better or final diagnosis can be delivered by WGS and/or WTS and if unclear cases can be efficiently resolved.
The objective of this study is to assess the safety and efficacy of anti-CD7 CAR T-cells in patients with refractory or relapsed T-lineage acute lymphoblastic leukemia (T-ALL).
