Number of participants with Adverse Events as a measure of safety and tolerability.
Time frame: 8 weeks
The single and multiple dose pharmacokinetics of PF-05190457 will be described by estimating parameters of Area Under the Curve (AUC) and its accumulation ratio on days 1, 13, and 14, as appropriate and the data permit.
Time frame: 2 weeks
The single and multiple dose pharmacokinetics of PF-05190457 will be described by estimating parameters of Maximum Concentration (Cmax) on days 1, 13, and 14, as appropriate and the data permit.
Time frame: 2 weeks
The single and multiple dose pharmacokinetics of PF-05190457 will be described by estimating parameters of Time of Maximum concentration (Tmax) on days 1, 13, and 14, as appropriate and the data permit.
Time frame: 2 weeks
The single and multiple dose pharmacokinetics of PF-05190457 will be described by estimating parameters of the Minimum Amount of concentration (Cmin) on days 13 and 14, as appropriate and the data permit.
Time frame: 2 weeks
The single and multiple dose pharmacokinetics of PF-05190457 will be described by estimating parameters of Elimination of half-life (t ½ ) on day 14, as the data permit.
Time frame: 2 weeks
The single and multiple dose pharmacokinetics of PF-05190457 will be described by estimating parameters of apparent total clearance of the drug from plasma after oral administration (CL/F) on days 13 and 14, as the data permit.
Time frame: 2 weeks
The single and multiple dose pharmacokinetics of PF-05190457 will be described by estimating parameters of apparent volume of distribution during terminal phase after non-intravenous administration (Vz/F) on days 13 and 14, as the data permit.
