Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Adverse Events (AEs)
Time Frame: 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.
Day -7 through the last follow-up (Day 68)
Number of Participants With Vital Signs Data Met Criteria of Potential Clinical Concern
Time Frame: Days -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.
Days -7 up to the last follow-up (Day 68)
Number of Participants With Electrocardiogram (ECG) Data Met Criteria of Potential Clinical Concern
Time Frame: Days -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.
Days -7 up to the last follow-up (Day 68)
Number of Participants With Positive Anti-PF-05231023 Antibodies and Neutralizing Antibodies.
Time Frame: 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.
Days 1 up to the last follow-up (Day 68)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
