What was measured

Terminal phase elimination half-life (T1/2) is the time required for half of the drug to be eliminated from the plasma.

Analysis population: The PK population consisted of all participants who had sufficient dosing data and ixazomib concentration-time data to permit calculation of ixazomib PK parameters.
