A Safety, Tolerability, Pharmacokinetics And Pharmacodynamics Study Of PF-06700841, With Bioavailability/Food Effect Investigation

Physical examinations included head, ears, eyes, nose, mouth, skin, heart and lung examinations, lymph nodes, gastrointestinal, musculoskeletal, and neurological systems.

An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; Initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug up to the end of study (up to Day 8 in SAD cohort, Day 28 in MAD cohort, Day 56 in MAD Psoriasis cohort, Day 37 in Food effect cohort), that were absent before treatment or that worsened relative to pretreatment state. AEs included both SAE and non-SAE.

An AE was any untoward medical occurrence attributed to study drug in a participant who received study drug. AEs were classified according to the severity in 3 categories a) mild - AEs does not interfere with participant's usual function b) moderate - AEs interferes to some extent with participant's usual function c) severe - AEs interferes significantly with participant's usual function.

AUCinf = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-inf).

Area under the plasma concentration time-curve from time zero to the time of last measured concentration (AUClast).

AUCinf = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-inf).

Area under the plasma concentration versus time curve from time 0 to end of dosing interval (AUCtau), where dosing interval was 24 hours for MAD once daily cohorts, 12 hours for MAD twice daily cohort and 24 hours for MAD Psoriasis cohort.

Area under the plasma concentration time-curve from time zero to the time of last measured concentration (AUClast).

Dose normalized (dn) Cmax was calculated by dividing Cmax by the exact dose of PF 06700841 (in mg) administered to a participant.

AUCinf = Area under the plasma concentration versus time curve (AUC) from time zero (pre-dose) to extrapolated infinite time (0-inf). AUCinf(dn) was calculated by dividing AUCinf by the exact dose of PF-06700841 (in mg) administered to a participant.

Area under the plasma concentration time-curve from time zero to the time of last measured concentration (AUClast). AUClast(dn) was calculated by dividing AUClast by the exact dose of of PF-06700841 (in mg) administered to a participant.

Area under the concentration curve from time 0 to end of dosing interval (AUCtau), where dosing interval was 24 hours for MAD once daily cohorts, 12 hours for MAD twice daily cohort. AUCtau(dn) was calculated by dividing AUCtau by the exact dose of of PF-06700841 (in mg) administered to a participant.

Plasma decay half-life is the time measured for the plasma concentration of PF-06700841 to decrease by one half.

MRT= AUMCinf/AUCinf, where AUMCinf is the area under the first moment curve from time 0 extrapolated to infinite time, calculated using the linear/log trapezoidal method.

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.

Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood. Clearance obtained after oral dose is influenced by the fraction of the dose absorbed. CL/F =Dose of PF-06700841/AUCinf.

PTF was calculated as: Cmax-Cmin/Cavg. Cmax is the maximum observed plasma concentration of PF-06700841. Cmin is the minimum observed plasma concentration of PF-06700841. Cavg is the average observed plasma concentration of PF-06700841 calculated as area under the plasma concentration-time curve during a dosing Interval (AUC[tau]) divided by the dosing interval (tau), where dosing interval was 24 hours for MAD once daily cohorts, 12 hours for MAD twice daily cohort and 24 hours for MAD Psoriasis cohort.

Aetau is the amount of drug recovered unchanged in urine during the dosing interval (tau), where dosing interval was 24 hours for MAD once daily cohorts, 12 hours for MAD twice daily cohort.

Aetau% was calculated as: 100*Aetau/dose. Aetau is the amount of drug recovered unchanged in urine during the dosing interval (tau), where dosing interval was 24 hours for MAD once daily cohorts, 12 hours for MAD twice daily cohort.

Renal clearance was calculated as amount of drug recovered unchanged in urine during the dosing interval tau (Aetau) divided by area under the plasma concentration time-curve from time zero to end of dosing interval (AUCtau), where dosing interval was 24 hours for MAD once daily cohorts, 12 hours for MAD twice daily cohort.
