Официальное название
Venetoclax, Cladribine Plus Low-dose Cytarabine for Relapsed/Refractory Philadelphia Chromosome-negative (Ph-) B-cell Acute Lymphoblastic Leukemia (B-ALL): a Single-arm, Multicenter Study
Обзор
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).
Подробное описание
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.
Вмешательства
- Препарат cladribine, cytarabine,venetoclax
Cladribine 5 mg/m2/day, cytarabine 20mg q12h, venetoclax 100mg d1, 200 d2, 400 mg/day from day 3 to day 21.

Вторичные конечные точки (3)
- Overall Survival (OS) [Срок оценки: 2 years]
