On Day 1, 3 participants in cohort 1 had reportable AUCtau values. On Day 71, 6 participants in cohort 1 and 2 participants in cohort 4 had reportable AUCtau values, 0,1,4 hours post-dose on Day 1 and Day 71|Apparent Oral Clearance (CL/F) on Day 71, Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Clearance was estimated from population pharmacokinetic (PK) modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood. On Day 71, 6 participants in cohort 1 had reportable CL/F values, 0,1,4 hours post-dose on Day 71|Maximum Observed Plasma Concentration (Cmax) on Day 1 and Day 71, Maximum serum concentration was observed directly from data on Day 1 and Day 71.

On Day 71, 2 participants in cohort 4 had reportable Tmax values, 0, 1, 4 hours post-dose on Day 1 and Day 71|Plasma Decay Half-Life (t1/2) on Day 71, Plasma decay half-life is the time measured for the plasma concentration to decrease by one half. On Day 71, 2 participants in cohort 1, 5 participants in cohort 2, and 7 participants in cohort 3 had reportable values for t1/2, 0, 1, 4 hours post-dose on Day 71|Apparent Volume of Distribution (Vz/F) on Day 71, Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed. On Day 71, 1 participant in cohort 1, 5 participants in cohort 2, and 7 participants in cohort 3 had reportable Vz/F values, 0, 1, 4 hours post-dose on Day 71|Accumulation Ratio (Rac) on Day 71, Accumulation ratio was calculated from AUCinf at last dose/AUCinf at first dose, where AUCinf is defined as area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-inf). It is obtained from AUC (0-t) plus AUC (t-inf). On Day 71, 3 participants in cohort 1 had reportable Rac values., 0, 1, 4, hours post-dose on Day 71
