A PHASE 1, RANDOMIZED, DOUBLE BLIND, SPONSOR-OPEN, PLACEBO-CONTROLLED STUDY TO EVALUATE THE SAFETY, TOLERABILITY, IMMUNOGENICITY AND PHARMACOKINETICS FOLLOWING SINGLE INTRAVENOUS DOSE OF PF-06823859 IN JAPANESE HEALTHY PARTICIPANTS

Number of Participants With Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)

Time Frame: Day 1 up to maximum of Day 157

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. SAE was any untoward medical occurrence that at any dose resulted in any of following outcomes/deemed significant for any other reason: death; initial /prolonged inpatient hospitalization; life-threatening; persistent or significant disability/incapacity; congenital anomaly/birth defect and suspected transmission via a Pfizer product of an infectious agent, pathogenic or non-pathogenic. TEAEs were the events between first dose of study drug and up to Day 157, that were absent before treatment or that worsened relative to pretreatment state. AEs included both serious (if occurred) and all non-serious adverse events.

Number of Participants With Infusion Related Reaction (IRR)

Time Frame: Day 1 up to maximum of Day 157

IRR included AEs potentially related to infusion related reaction and was determined by blind medical review prior to the database release.

Number of Participants With Electrocardiogram (ECG) Abnormalities of Pre-defined Criteria

Time Frame: From baseline (pre-dose measurement at Day 1) up to Day 157

Criteria for ECG abnormalities: maximum PR interval \>=300 milliseconds (msec); maximum increase in PR interval from baseline \>=25 percent (%) for baseline value of \>200 msec; maximum increase in PR interval from baseline \>=50% for baseline value of less than or equal to (\<=) 200 msec; maximum QRS interval \>=140 msec and maximum increase from baseline \>=50%; QT interval of \>=500 msec; QTcF interval (Fridericia's Correction of QTc interval) mild: \>=450 msec to \<480 msec, moderate: \>=480 msec to \<500 msec; increase from baseline \>=30 msec to \<60 msec and severe: \>=500 msec; increase from baseline \>=60 msec.

Number of Participants With Viral Infection

Time Frame: Day 1 up to maximum of Day 157

Number of Participants With Infusion Site Reaction

Time Frame: From start of study intervention infusion up to 60 minutes on Day 1

Participants were monitored from start of study intervention infusion until the end of infusion to assess the infusion sites for erythema, induration, ecchymosis, pain, and pruritus, or other observed characteristics after study intervention.

Number of Participants With Laboratory Test Abnormalities

Time Frame: Day 1 up to maximum of Day 157

Laboratory test abnormalities included hematology: basophils/leukocytes greater than (\>)1.2\* upper limit of normal (ULN), eosinophils/leukocytes \>1.2\* ULN, monocytes/leukocytes \>1.2\* ULN; clinical chemistry: bilirubin \> 1.5\* ULN, aspartate aminotransferase \>3.0\* ULN, urate \>1.2\* ULN; urinalysis: ketones greater than or equal to (\>=)1, urine hemoglobin \>=1.

Number of Participants With Vital Sign Abnormalities of Pre-defined Criteria

Time Frame: From baseline (pre-dose measurement at Day 1) up to Day 157

Vital sign abnormalities were categorized as: a) supine systolic blood pressure: minimum: less than (\<) 90 millimeter of mercury (mmHg), maximum decrease from baseline: greater than or equal to (\>=) 30 mmHg, maximum increase from baseline: \>=30 mmHg; b) supine diastolic blood pressure: minimum: \<50 mmHg, maximum decrease from baseline: \>=20 mmHg, maximum increase from baseline: \>=20 mmHg; c) supine pulse rate: minimum \<40 beats per minute (bpm), maximum \>120 bpm. Number of participants with any vital sign abnormality were reported in this outcome measure.
