Accumulation Ratio for Area Under the Curve From Time Zero to End of Dosing Interval of PF-05231023 (Rac)

Rac was obtained from AUCtau at steady state (Day 25) divided by AUCtau after single dose (Day 1). AUCtau was the area under the concentration-time profile from time zero to end of dosing interval, where tau = 72 hours for Day 1 and tau = 96 hours for Day 25. Participants who received PF-05231023 with C-terminal and N-terminal Rac at steady state were reported.

Time frame: 0 hour (pre-dose) on Day 1, 4, 25; 0.5, 1 (end of infusion), 1.5, 2, 3, 5, 9, 13 hours post-start of infusion on Day 1, 25; Day 2, 3, 26, 29

Population: PK parameter analysis set included all enrolled and treated participants who had at least 1 of the PK parameters of interest. 'N' (number of participants analyzed) signifies those participants who were evaluable for this outcome measure.

Volume of Distribution of PF-05231023 at Steady State (Vss)

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. Vss is the apparent volume of distribution at steady-state. PF-05231023 with C-terminal and N-terminal Vss at steady state were reported.

Time frame: 0 hour (pre-dose) 0.5, 1 (end of infusion), 1.5, 2, 3, 5, 9, 13 hours post-start of infusion on Day 25; Day 26, 29

Population: PK parameter analysis set included all enrolled and treated participants who had at least 1 of the PK parameters of interest. n signifies those participants who were evaluated for this measure at the specified terminal for each arm.
