简要总结
The purpose of this study is to evaluate the safety and efficacy of Venetoclax Combining Chidamide and Azacitidine (VCA) Followed by D-MAG Regimen on the Treatment of Elderly Patients With Newly Diagnosed Acute Myeloid Leukemia (AML)
详细描述
Elderly Patients with AML have inferior outcomes due to poor physical condition, and intolerant to conventional chemotherapy. The regimen of Venetoclax and Azacitidine has been widely used in these patients and has proved to achieve higher CR rate than low intensity therapy. However, the median duration of response (DOR) of this regimen is about one year. Chidamide is a histone deacetylase (HDAC) inhibitor and preclinical data showed adding low-dose Chidamide to venetoclax could significantly promoted apoptosis of leukemia cell lines. The Venetoclax Combining Chidamide and Azacitidine (VCA) regimen was applied to one 62-year-old male patient with AML who achieved CR. Meanwhile, Liposome mitoxantrone has better safety and tolerance than mitoxantrone in elderly patients. Thus, this study is intended to use 2 cycles of VCA regimens followed by 2 cycles of D-MAG regimens, and then repeat the above four courses of treatment once to improve the median event free survival of elderly AML patients.
