Study Evaluating Orally Administered AMG 900 in Adult Subjects With Acute Myeloid Leukemia

This study has been completed.

Amgen Identifier:
First received: June 9, 2011
Last updated: February 18, 2015
Last verified: January 2015
This study of AMG 900 will be conducted in two parts: dose escalation and dose expansion. The dose escalation part of the study is aimed at evaluating the safety, tolerability and PK (pharmacokinetics) of oral AMG 900 in subjects with acute myeloid leukemia. Up to 93 subjects may be enrolled in dose escalation. The dose expansion part of the study will consist of 20 subjects with acute myeloid leukemia. The dose of AMG 900 will be dependent upon data from the dose escalation part of the study.

  • Maximum observed concentration of AMG 900 [ Time Frame: 1 year ]
  • Time to maximum observed concentration of AMG 900 [ Time Frame: 1 year ]
  • Area under the plasma concentration-time curve (AUC) of AMG 900 [ Time Frame: 1 year ]
  • Half life of AMG 900 [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • Objective response as per Cheson Response Criteria [ Time Frame: 1 year ]

Enrollment: 35
Study Start Date: July 2011
Study Completion Date: January 2015
Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm 1- Dose Escalation
The dose escalation will be conducted in 2 parts. Group 1 will consist of 8 cohorts and Group 2 will consist of 5 cohorts. The dose escalation is aimed at determining the maximum tolerated dose (MTD) of AMG 900.
Drug: Arm 1- Dose Escalation
AMG 900 is a small molecule aurora kinase inhibitor. AMG 900 will be administered daily for 4 days every 2 weeks or daily 7 days every 2 weeks (ie.g., 4 consecutive days of dosing followed by 10 consecutive days off treatment).
Experimental: Arm 2- Dose Expansion
The dose expansion part of the study will begin after completion of the dose escalation phase and will consist of 20 subjects with acute myelogenous leukemia.
Drug: Arm 2- Dose Expansion
AMG 900 is a small molecule aurora kinases inhibitor. The dose expansion phase would be conducted to gain further clinical experience with AMG 900 in AML at the optimal dose schedule.
