Multi-center Phase II Prospective Study for the Treatment of Chidamide and Venetoclax in Patients With All-trans Retinoic Acid (ATRA) and Arsenic (As) Resistant Acute Promyelocytic Leukemia (APL)
Based on the current treatment with retinoic acid (ATRA) and arsenic (As), most patients with APL achieved long-term survival. There are few patients relapsed and became refractory to the RA and As treatment. In our pre-clinical study, we found that targeting histone deacetylase inhibitor 3 (HDAC3)degraded PML-RARa oncoprotein and induced differentiation and apoptosis of RA and As resistant APL in vitro and in vivo. In this study, we evaluate the efficacy and feasibility of combination therapy for HDAC3 inhibitor and venetoclax in patients with refractory APL.
• Patients with PML-RARα+ APL
• Patients in non-remission status after treatment of RA combined with As
