Recruitment status

TERMINATED

Study phase

PHASE1

Target enrollment

Participant Flow

Participants took part in the study at single site in the United States from 04 August 2014 to 09 December 2014.

Part A was performed on non-Japanese participants and Part B was performed on Japanese participants. Planned doses of MLN3126 800 mg to be decided (TBD) dose for Part A, and MLN3126 300 mg, 800 mg, and TBD dose for Part 2 were not administered due to early termination of the study.
