VHAG in Treating R/R T-ALL/LBL

December 16, 2024 updated by: First Affiliated Hospital of Zhejiang University

Venetoclax Combined With HAG Regimen in Treating Adult Relapse/Refractory Acute T Cell Lymphoblastic Leukemia/Lymphoma: A Phase II, Single Arm and Multicenter Study

Acute T cell lymphoblastic leukemia/lymphoma (T-ALL/LBL) is an aggressive type of leukemia that results from the malignant evolution of T-lineage progenitor cells at different differentiation stages. After induction chemotherapy and consolidation chemotherapy, there are still about 30% of patients who cannot achieve complete remission of clinical symptoms or negative MRD. This is also an important factor for the recurrence of ALL patients. In addition, most relapsed T-ALL/LBL patients relapse during first-line treatment. Once the disease relapses, it is difficult to cure for most young and adult patients, and the overall survival rate of patients is less than 10%.

Detailed Description

This is a prospective, single-arm, phase II and open-label study. A total of 50 R/R T-ALL/LBL participants will be enrolled. The primary endpoint is complete remission with or without peripheral blood cell recovery. The induction therapy is a combination of Venetoclax(Ven), Homoharringtonine(HHT) , Cytarabine and G-CSF. The purpose of this study is to explore efficacy of the VHAG in the treatment of R/R T-ALL/LBL patients.
