What was measured

Terminal elimination rate constant, calculated as the negative of the slope of the log-linear regression of the natural logarithm concentration-time curve during the terminal phase.

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.
