Primary Outcome Measures
NameTimeMethod
Number of Participants With Adverse Events (AEs)Day -7 through the last follow-up (Day 68)

An AE was defined as any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. AEs were also reported for the 7-day pre-randomization period.

Number of Participants With Vital Signs Data Met Criteria of Potential Clinical ConcernDays -7 up to the last follow-up (Day 68)

Vital signs included supine systolic blood pressure, diastolic blood pressure and pulse rate. Vital signs criteria of potential clinical concern were 1), blood pressure: systolic greater than or equal to (\>=)30 millimeters of mercury (mm Hg) change from baseline in the same posture or systolic less than (\<)90 mm Hg; diastolic \>=20 mm Hg change from baseline in the same posture or diastolic \<50 mm Hg; 2), Pulse rate: supine/Sitting: \<40 or greater than (\>) 120 beats per minute (bpm); Standing: \<40 or \>140 bpm.

Number of Participants With Electrocardiogram (ECG) Data Met Criteria of Potential Clinical ConcernDays -7 up to the last follow-up (Day 68)

ECG criteria of potential clinical concern were 1), PR interval:\>=300 msec, \>=25% increase when baseline \>200 msec, or \>=50% increase when baseline \<=200 msec; 2), QRS interval:\>=140 msec, or \>=50% increase from baseline; 3), QT interval corrected for heart rate (QTc)/QTc interval using Fridericia's formula (QTcF):\>=500 msec, QTcF interval: absolute value \>=450 - \<480 msec(borderline), \>=480 msec (prolonged), absolute change 30 - \<60 msec (borderline) or \>=60 msec (prolonged). 12-lead ECG (triplicate) was performed on Day 0 and 12-lead ECG (singlet) was performed at other times.

Number of Participants With Positive Anti-PF-05231023 Antibodies and Neutralizing Antibodies.Days 1 up to the last follow-up (Day 68)

Anti-PF-05231023 antibodies were analyzed using a tiered testing strategy of screen, confirm, and titer characterization. Positive was defined as titer value \>=6.23 and negative was defined as titer value \<6.23. Samples tested positive were also to be analyzed in a neutralization assay to determine whether or not they were neutralizing or non-neutralizing.

Secondary Outcome Measures
NameTimeMethod
Number of Participants With Abnormal Clinical Laboratory MeasurementsDays -7 up to the last follow-up (Day 68)

The total number of participants with laboratory test abnormalities without regard to baseline abnormality was assessed.
