The first model was developed from a resistant/relapsed patient with FLT3-ITD mutation and complex karyotype. The combination showed the most significant antileukemic activity and extension of survival, followed by AMG 176 and VEN treatment alone (median survival for the combination, 146 d, p=0.004; AMG 176, 137 d, p=0.032; VEN, 102 d, p>0.05 vs. control, 85.5 d; respectively).
