A Study to Learn About The Study Medicine (Called PF-06823859) in Healthy Chinese Participants

Phase 1

Completed

• Conditions: Healthy
• Interventions: Other: Placebo; Drug: IFN-β inhibitor treatment

• Registration Number: NCT05257798
• Lead Sponsor: Pfizer

Brief Summary

The purpose of this clinical trial is to learn if the study medicine (called PF-06823859) is safe and how it is processed in healthy Chinese participants. This study is seeking participants who:

* Are between 18 to 45 years of age, inclusive, at the time of signing the Informed Consent Document (ICD).

* Are Chinese participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and 12 lead ECG (electrocardiogram).

* Have a BMI (body mass index) of 19 to 27 kg/m2 (inclusive); and a total body weight \>50 kg (110 lb).

All participants in this study will receive PF-06823859 or a placebo. A placebo does not have any medicine in it but looks just like the medicine being studied. PF-06823859 will be given as an infusion directly into a vein. We will compare the experiences of people receiving PF-06823859 to those of people who do not. This will help us determine if PF-06823859 is safe and how it behaves inside the human body.

Participants will take part in this study for up to 157 days. During this time, they will receive PF-06823859 or placebo and be observed for any effects.

Detailed Description

This is a Phase 1, randomized, double blind, sponsor open, placebo controlled study to evaluate the PK, safety, and tolerability following a single dose of PF 06823859 (900 mg) in healthy Chinese participants.

Arm && Interventions

Group	Intervention	Description
Placebo	Placebo	Participants will receive placebo via IV.
PF-06823859	IFN-β inhibitor treatment	Participants will receive 900 mg of PF-06823859 via intravaneous (IV).

Primary Outcome Measures

Name	Time	Method
Time at Which Cmax Occured (Tmax) for PF-06823859 in Serum	Days 1 (pre-dose, 1, 2, 6, 12 hours post dose), 2,3,5,15,29,43,57,71,100,127 and 157.	The Tmax was the time at which Cmax occurs
Maximum Serum Concentration(Cmax) for PF-06823859	Days 1 (pre-dose, 1, 2, 6, 12 hours post dose), 2,3,5,15,29,43,57,71,100,127 and 157.	The Cmax was observed directly from data.
Number of Participants With Laboratory Test Abnormalities (Without Regard to Baseline Abnormality).	Days -1, 2, 5,8,15,29,57,100,127 and 157.	Safety laboratory assessments included urinalysis, hematology, chemistry and other. All the safety laboratory samples were collected following at least a 4-hour fast.
Area Under the Concentration-time Profile From Time Zero to 14 Days (336 Hours) Post-dose (AUC14day) for PF-06823859 in Serum	Days 1 (pre-dose, 1, 2, 6, 12 hours post dose), 2,3,5,15,29,43,57,71,100,127 and 157.	The AUC14day was area under the concentration-time profile from time zero to 14 days post-dose (336 hours)
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)	From first dose of study drug/Day 1 to Day 157	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 up to follow-up visit that were absent before treatment or that worsened after treatment. 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.
Number of Participants With Pre-Specified Categorization for Vital Signs (Diastolic Blood Pressure)	Days 1 (pre-dose),5,29,57,100,127 and 157.	Vital signs measurements included supine blood pressure, diastolic blood pressure, pulse rate and temperature. For diastolic blood pressure, the reporting criteria is increase or decrease from baseline of \>= 20mmHg or absolute value \< 50 mmHg.
Number of Participants With Viral Infections	From Screening up to Day157	Viral infections surveillance was conducted throughout the study for cytomegalovirus (CMV), Epstein Barr virus (EBV), herpes simplex virus type 1 (HSV-1),herpes simplex virus type 2 (HSV-2), varicella zoster virus (VZV)， Human Herpes Virus 6 (HHV6) and COVID-19.

Number of Participants With Pre-Specified Categorization (Maximum Change From Baseline) for ECG Data	Days -1, 5,29,57,100,127 and 157.	Standard 12 lead ECGs utilizing limb leads (with a 10 second rhythm strip) were collected at pre-specified times using an ECG machine that automatically calculates the heart rate and measures PR, QT, and QTc intervals and QRS complex. For Safely QTc assessments, absolute value of \>450msec and \< 480msec is defined as mild prolongation; absolute value between 480-500msec or an increase from baseline of 30 -60msec are defined as moderate prolongation; an absolute value of \> 500msec or increase from baseline of \>60 msec are defined as severe prolongation.
Area Under the Serum Concentration-time Profile From Time Zero Extrapolated to Infinite Time(AUCinf) for PF-06823859 in Serum.
