Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

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.
