What was measured

Number of participants in each arm of this OM is based on the actual treatment received. 1 participant originally assigned to the 200/100 mg arm received the 100/100 mg treatment and hence, was counted under the 100/100 mg arm for this OM.

Analysis population: PK evaluable population included all participants who received at least one dose of pralsetinib and from whom at least one post dose PK sample was collected. Overall number analyzed is the number of participants with data available for analysis. Number analyzed is the number of participants with data available for analysis at the specified timepoint.
