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

CompletedPhase 1

Sponsor: Pfizer

Conditions: Healthy

Interventions: IFN-β inhibitor treatment, Placebo

Countries: China

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.
