Brief Summary

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

This will be an investigator- and subject-blinded (sponsor open), randomized, placebo controlled, sequential, ascending, multiple oral dose study, with 5 planned cohorts (optional sixth and seventh cohorts). A total of approximately 50 (if 5 cohorts), 60 (if 6 cohorts), and up to 70 (if 7 cohorts) subjects will be randomized in this study. Subjects in each cohort will be randomized to receive PF-06865571 or matching placebo with approximately 10 subjects dosed in each cohort.

For a given subject in any cohort, the total study duration from screening to follow-up phone call will be between approximately 7 to 11 weeks.

* Subjects with fasting LDL-C level \>190 mg/dL following an overnight fast of at least 10 hours, at the Screening visit, confirmed by a single repeat, if deemed necessary.
* Subjects with fasting TG level \>400 mg/dL following an overnight fast of at least 10 hours, at the Screening visit, confirmed by a single repeat, if deemed necessary.
* Any condition possibly affecting drug absorption (eg, gastrectomy).
* A positive urine drug test.
* History of regular alcohol consumption exceeding 7 drinks/week for female subjects or 14 drinks/week for male subjects (1 drink = 5 ounces \[150 mL\] of wine or 12 ounces \[360 mL\] of beer or 1.5 ounces \[45 mL\] of hard liquor) within 6 months before screening.
* Treatment 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 (whichever is longer).
* Use of tobacco- or nicotine-containing products in excess of the equivalent of 5 cigarettes per day or 2 chews of tobacco per day.

* Unwilling or unable to comply with the criteria in the Lifestyle Requirements section of this protocol.
* 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 subject inappropriate for entry into this study.
