What was measured

Ratio to baseline was calculated dividing post-baseline measurements by the baseline measurement. Single dose Pd data on Day 1 were summarized by dose level, such that all 10 mg arms were combined as descriptive statistics of PK were only calculated for N greater than (\>) 2 in which a measurement of greater than (\>) lower limit of quantification (LLOQ) represents a valid measurement.

Analysis population: The Pharmacodynamic (Pd) population included all participants who received at least one dose of study intervention, had no clinically important protocol deviations or important events affecting Pd, and provide at least one measurable Pd endpoint post-dose. Here, "Overall Number of Participants Analyzed" signifies those participants who were evaluable for this outcome measure and "Number Analyzed" signifies those participants who were evaluable for specified timepoints.
