Inclusion Criteria. | 18 years and older, who had advanced Acute Myeloid Leukemia, ECOG score of 0-2 and harbor IDH mutation, AML or MDS with refractory anemia and excess blast. | 18 years and older, who had advanced Acute Myeloid Leukemia, ECOG score of 0-2 and harbor IDH mutation, AML or MDS with refractory anemia and excess blast. | |||
Characteristics of the genetic mutations in AML patients. | Out of total 239 subjects, 117 had intermediate Cytogenetics risk status (67%) and 58 (33%) had poor Cytogenetics risk status. 17 patients had NPM1 gene mutation, CEBPA mutation found in 10 patients while FLT3-ITD found in 4 subjects. Antecedent history of MDS in 30 subjects and 28 subjects had prior stem cell transplantation. 179/239 had RI40 mutation, while 57/239 had RI72 mutation. 176/239 patients had RR AML and constitutes our primary interest in our meta-analysis. | ||||
Number of previous lines of chemotherapy/ Percentages of relapse and refractory AML. | 176 patients had RR AML. 43 subjects relapsed after 2 or more cycles, 41 relapsed within 1 year of initial treatment, 24 relapsed after transplant, 22 had second or more relapses and 15 relapsed after 1 year. | 176 patients had RR AML. 43 subjects relapsed after 2 or more cycles, 41 relapsed within 1 year of initial treatment, 24 relapsed after transplant, 22 had second or more relapses and 15 relapsed after 1 year. |
