Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum Observed Concentration (Cmax) of PF-06480605	Cmax is the maximum observed plasma concentration.	At 0 (prior to dose), 2, 6, 24, 48, 72, 96, 216, 336, 672, 1008, 1344, 2016, and 2712 hours post dose on Day 1
Primary	Time for Cmax (Tmax) of PF-06480605	Tmax is the time for Cmax.	At 0 (prior to dose), 2, 6, 24, 48, 72, 96, 216, 336, 672, 1008, 1344, 2016, and 2712 hours post dose on Day 1
Primary	Area Under the Curve From Time 0 to End of Dosing Interval (AUC14day) of PF-06480605	AUC14day is area under the curve from time 0 to end of dosing interval (Day 14, 336 hours).	At 0 (prior to dose), 2, 6, 24, 48, 72, 96, 216, and 336 hours post dose on Day 1
Primary	Area Under the Plasma Concentration Time Profile From Time 0 Extrapolated to Infinite Time (AUCinf) of PF-06480605	AUCinf is area under the plasma concentration time profile from time 0 extrapolated to infinite time.	At 0 (prior to dose), 2, 6, 24, 48, 72, 96, 216, 336, 672, 1008, 1344, 2016, and 2712 hours post dose on Day 1
Primary	Terminal Half-life (t1/2) of PF-06480605	t1/2 is the terminal half-life (time required for the plasma concentration to decline by 50%)	At 0 (prior to dose), 2, 6, 24, 48, 72, 96, 216, 336, 672, 1008, 1344, 2016, and 2712 hours post dose on Day 1
Secondary	Number of Participants With Treatment Emergent Adverse Events (TEAEs)	An adverse event (AE) was any untoward medical occurrence in a participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. A serious AE (SAE) was defined as any untoward medical occurrence that, at any dose: resulted in death; was life-threatening; required inpatient hospitalization or prolongation of existing hospitalization; resulted in persistent disability/incapacity; was a congenital anomaly/birth defect; or other serious situations such as important medical events. TEAEs were events between first dose of study drug and before the end of study (up to follow-up visits). AEs presented below were TEAEs. The investigator was required to use clinical judgment to assess the potential relationship between investigational product and each AE, to define an treatment-related AE.	Day 1 to Day 114
Secondary	Number of Participants With Change From Baseline in Vital Signs Data Meeting the Pre-defined Categorical Summarization Criteria	Vital signs abnormalities included: supine diastolic blood pressure (BP) increase and decrease from BL of >=20mmHg or absolute value <50mmHg; systolic BP increase and decrease from BL of >=30mmHg or absolute value <90mmHg; pulse rate <40 or >120bpm.	From Baseline (BL) to Day 114
Secondary	Number of Participants With Change From Baseline in Electrocardiogram (ECG) Data Meeting the Pre-defined Categorical Summarization Criteria	ECG assessments included PR, QT, and QTc intervals and QRS complex. ECG abnormalities included PR interval BL >200msec and max >=25% increase from BL, or BL <=200msec and max >=50% increase from BL, or absolute value >=300msec; QRS interval percent change from BL >=50% or absolute value >=140msec, QTcF change from BL >=30msec, or absolute value >450msec.	From BL to Day 114
Secondary	Number of Participants With Clinical Laboratory Abnormalities (Without Regard to Baseline Abnormality)	Safety laboratory assessments included clinical chemistry, hematology, urinalysis, and other tests. Abnormality was determined at the investigator's discretion. Laboratory test abnormalities reported by at least 1 participant are reported in this outcome measure.	From BL to Day 114
Secondary	Area Under the Plasma Concentration-time Profile From Time 0 to the Time of the Last Quantifiable Concentration (AUClast) of PF-06480605	AUClast is area under the plasma concentration-time profile from time 0 to the time of the last quantifiable concentration	At 0 (prior to dose), 2, 6, 24, 48, 72, 96, 216, 336, 672, 1008, 1344, 2016, and 2712 hours post dose on Day 1
Secondary	Apparent Volume of Distribution (Vz/F) of PF-06480605	Vz/F is the apparent volume of distribution, 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.	At 0 (prior to dose), 2, 6, 24, 48, 72, 96, 216, 336, 672, 1008, 1344, 2016, and 2712 hours post dose on Day 1
Secondary	Apparent Oral Clearance (CL/F) of PF-06480605	CL/F is the apparent oral clearance, which is influenced by the fraction of the dose absorbed. Clearance was estimated from population PK modeling. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.	At 0 (prior to dose), 2, 6, 24, 48, 72, 96, 216, 336, 672, 1008, 1344, 2016, and 2712 hours post dose on Day 1

Secondary	Number of Participants With Neutralizing Antibody (NAb) Against PF-06480605	Summary of NAb incidence by visit is presented. NAb positive was defined as titer >=5. ADA-positive participants (defined as titer >=60) were analyzed for NAb.	On Days 1 (prior to dose), 15, 29, 57, 85 and 114
