Inclusion criteria

* Participants who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, lifestyle considerations, and other study procedures. * Body mass index (BMI) of 17.5 to 35.4 kg/m2, inclusive; and a total body weight \>50 kg (110 lb), at the Screening visit; with a single repeat assessment of total body weight (and hence BMI), on a separate day permitted to assess eligibility, if needed. * Capable of giving signed informed consent.

Exclusion criteria

* Any condition possibly affecting drug absorption (eg, prior bariatric surgery,gastrectomy, ileal resection). * At Screening, participants with a positive result for human immunodeficiency virus (HIV) antibodies, as assessed by sponsor-identified central laboratory, with a single repeat permitted to assess eligibility, if needed. * Other acute or chronic medical or psychiatric condition including recent (within the past year) or active suicidal ideation or behavior or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the participant inappropriate for entry into this study. * Previous administration with an investigational drug within 30 days (or as determined by the local requirement) or 5 half-lives preceding the first dose of investigational product used in this study (whichever is longer). * Participants with known prior participation (ie, randomized and received at least 1 dose of investigational product) in a study involving PF-06865571. * A positive urine drug test, for illicit drugs on Day -1, * At Screening or Day -1, a positive breath alcohol test. * Male participants with partners who are currently pregnant. * Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 60 days prior to dosing and until the follow-up contact. * Unwilling or unable to comply with the criteria in the Lifestyle Considerations. * Investigator site staff members directly involved in the conduct of the study and their family members, site staff members otherwise supervised by the investigator, or Pfizer employees, including their family members, directly involved in the conduct of the study.

MeasureTime frameDescription
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)Up to Day 32 (31 days after investigational product administration)An adverse event (AE) was any untoward medical occurrence attributed to study drug in a participant who receives study drug. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. TEAEs were events following start of treatment.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs)

An adverse event (AE) was any untoward medical occurrence attributed to study drug in a participant who receives study drug. A serious adverse event (SAE) was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. TEAEs were events following start of treatment.

Time frame: Up to Day 32 (31 days after investigational product administration)

Population: All participants who received PF-06865571.
