Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to investigate the efficacy and safety of cladribine, venetoclax combined with cytarabine and venetoclax (CAV regimen) for relapsed/refractory (R/R) Philadelphia Chromosome-negative (Ph-) B-cell acute lymphoblastic leukemia (B-ALL).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Relapse is common in Ph- B-ALL and a proportion of patients present refractory to initial treatment. Treatments for these patients consist immunotherapy and conventional chemotherapy. The former is too expensive and the latter has a low remission rate. Treatment for R/R Ph- B-ALL still remains a challenge. The efficacy and safety of cladribine, venetoclax and cytarabine (CAV) has not been explored in ALL. Thus investigators design such a clinical trial to investigate the efficacy and safety of CAV regimen for R/R Ph- B-ALL.
