Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to understand the effect of tablet formulation and presence of food on the study medicine PF-06821497 in healthy adult participants.

The study is seeking for male and female participants who:

* Are 18 years of age or more.
* Are confirmed to be healthy after performing some medical and physical tests.
* Weigh more than 50kgs of body weight and have a body mass index of 17 and a half kg per meter squared or more.

The study consists of two parts. In each part of the study, the selected participants will take part in 3 study periods to receive 3 different treatments which are randomly assigned. There will also be a 5-day gap between each study period. This is done so that the medicine is passed out of the body before the start of next study period.

Each treatment consists of a single dose of PF-06821497. The treatments differ by tablet formulation and/or whether the medicine is to be given with food or without food conditions.

How the medicine is processed in the body will be studied after giving the medicines to the participants. This will be done by collecting blood samples after each administration. The results will be used to see the effect of tablet formulation and presence of food on the amount of PF-06821497 available in the blood of the participants.

In each part, participants will be on the study up to 10 weeks, including the screening and follow-up periods.

* Male and female participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, vital signs and 12-lead ECGs.
* BMI of ≥17.5 kg/m2; and a total body weight \>50 kg (110 lb)
* Evidence of a personally signed and dated ICD indicating that the participant has been informed of all pertinent aspects of the study.
* Participants who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, lifestyle considerations, and other study procedures.

Exclusion Criteria

* Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurological, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing) or prior allergic reaction to any component of PF-06821497.
* Other medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality or other conditions or situations related to COVID-19 pandemic that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study.
