Vz/F of PF-06840002 (Active Enantiomer) and PF-06840001 (Inactive Enantiomer) was determined by Dose/(AUC*kel). AUC is the area under concentration curve and kel is the terminal phase rate constant calculated by a linear regression of the log-linear concentration time curve. The analysis population included all enrolled participants treated who had sufficient information to estimate at least 1 of the PK parameters of interest.
Time Frame
Cycle 1 Day 15 pre-dose, 1, 2, 4, 6, 8, 24 hrs post
Title
Multiple Dose: Observed Accumulation Ratio (Rac) of PF-06840002 and PF-06840001 [Part 1]
Description
Rac of PF-06840002 (Active Enantiomer) and PF-06840001 (Inactive Enantiomer) was determined by AUCtau (steady state) / AUCtau (single dose).
Time Frame
Cycle 1 Day 15 pre-dose, 1, 2, 4, 6, 8, 24 hrs post
Title
Multiple Dose: Steady State Accumulation Ratio (Rss) of PF-06840002 and PF-06840001 [Part 1]
Description
Rss of PF-06840002 (Active Enantiomer) and PF-06840001 (Inactive Enantiomer) was determined by AUCtau (steady state) / AUCinf (single dose). The analysis population included all enrolled participants treated who had sufficient information to estimate at least 1 of the PK parameters of interest.
Time Frame
Cycle 1 Day 15 pre-dose, 1, 2, 4, 6, 8, 24 hrs post
Title
Steady-State Trough Level Ratio [Part 1]
Description
Steady-State trough level ratio was determined by cerebrospinal fluid (CSF)/Plasma. CSF/Plasma ratio was calculated based on the unbound concentration of each analyte. The analysis population included all enrolled participants treated who had sufficient information to estimate at least 1 of the PK parameters of interest.
Time Frame
Baseline and Day 15
Title
Plasma Kynurenine and Tryptophan [Part 1]
Description
The levels of Kynurenine and Tryptophan in blood samples were determined using the qualified analytical method.
Time Frame
Cycle 1 Day 1 pre-dose, and 1, 2, 4, 6, 8, 24 hours post-dose; Cycle 1 Day 4 and Day 8 pre-dose; Cycle 1 Day 15 pre-dose, and 1, 2, 4, 6, 8, 24 hours post-dose
Title
Plasma Endogenous Kynurenine/Tryptophan Ratio [Part 1]
Description
The Kynurenine/Tryptophan ratio was determined by 1000*Kynurenine/Tryptophan.
Time Frame
Cycle 1 Day 1 pre-dose, and 1, 2, 4, 6, 8, 24 hours post-dose; Cycle 1 Day 4 and Day 8 pre-dose; Cycle 1 Day 15 pre-dose, and 1, 2, 4, 6, 8, 24 hours post-dose
