A study testing CAR-T cells and Venetoclax in people with Philadelphia Chromosome Negative ALL and Acute Lymphoblastic Leukemia, Adult, run by Institute of Hematology & Blood Diseases Hospital, China at 1 site in China.
Trial summary
In recent years, immunotherapy (eg. blinatumomab, inotuzumab ozogamicin, CAR-T cells) has demonstrated a high safety and efficacy profile in relapsed/refractory (R/R）B-ALL. The available data suggest that the advancement of immunotherapy from relapsed/refractory (R/R) field to the frontline setting may be an important… Read more about this study

About this study
Official title: Efficacy and Safety of Chemotherapy Combined With CAR-T Cells in Newly Diagnosed Adult Patients With Philadelphia Chromosome-Negative B-cell Acute Lymphoblastic Leukemia
In recent years, immunotherapy (eg. blinatumomab, inotuzumab ozogamicin, CAR-T cells) has demonstrated a high safety and efficacy profile in relapsed/refractory (R/R）B-ALL. The available data suggest that the advancement of immunotherapy from relapsed/refractory (R/R) field to the frontline setting may be an important approach to increase the depth of remission, which ultimately translates into a survival benefit. In this study, the investigators propose a treatment regimen using CAR-T cell therapy as a consolidation method for Ph- B-ALL patients achieving complete remission (CR) with chemotherapy, aiming to reduce the total cycles of chemotherapy and related toxicities, shorten length of hospitalization, and ultimately improve patients' survival and quality of life.The study endpoints include 2-year disease-free survival (DFS) rate, overall survival (OS) rate, event-free survival (EFS) rate, cumulative molecular remission rate, immune repertoire-minimal residual disease (MRD) remission rate, cumulative relapse rate, treatment-related toxicities, and quality of life. Additionally, an interim analysis will be conducted, with the 1-year DFS rate as the key index for this analysis.
Read the detailed description
The CAR-T cells were murine-derived second-generation CD19 CAR-T with a co-stimulation domain of 4-1BB, and the infusion dose was 1×10^6/kg CAR+ cells in a single infusion.
