The Study Drug:~Azacitidine is designed to block certain genes in cancer cells whose job is to stop the function of the tumor-fighting genes. By blocking the bad genes, the tumor-fighting genes may be able to work better.~Chidamide exhibits potent inhibitory effect on cell viability of MDS and AML cells, and the possible mechanism may lie in the downregulation of JAK2/STAT3 signaling through SOCS3 upregulation.~Study Group： If you are found to be eligible to take part in this study,you will receive azacitidine and chidamide.~Study Drug Administration:~You will recieve six courses of azacitidine through a needle under your skin on Days 1-5.Each course is 28 days long.At the same time you will recieve oral chidamide per day for no more than 2 years.~The treatment will start after 60 days post-transplantation and your neutrophil count is of 1.5 × 10⁹ cells per L or higher and non-transfused platelets is of 80 × 10⁹ per L or higher.~The treatment would stop if neutrophil count is less than 0.5 × 10⁹ cells per L or platelets is less than 20 × 10⁹ per L.And it would also stop when grade 3/4 non-hematological adverse events happened.~Study Visit:~You may come back for study visits every month in a year when the treatment start.~Blood and urine will be drawn for routine tests every month. At 1,2,3,4,5,6,9 and 12 months,You will have a bone marrow aspiration to check the status of the disease.~You will have a electrocardiiogram test every 3 months to check the heart function.~Length of Study:~You will be on study treatment for up to 1 year.You will be taken off study early if you experience intolerable side effects or the disease gets worse.~End-of-Treatment Visit:~If you complete the planned treatment with azacitidine and chidamide, you will have an end-of-treatment visit:~Blood and urine will be drawn for routine tests. You will have a bone marrow aspiration to check the status of the disease. You will have a electrocardiiogram test every 3 months to check the heart function.~This is an investigational study. Azacitidine and chidamide are FDA approved and are commercially available for the treatment of acute leukemia.
The goal of this clinical research study is to learn if azacitidine combined with Chidamide will help to control the disease in patients with high-risk AML after an allogeneic stem cell transplant. The safety of this combination will also be studied.
