Outcome Measures

Primary Outcome Measures :

1. Maximum Observed Plasma Concentration (Cmax) of Metformin (in absence of PF-06865571) [ Time Frame: 0, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24, 48 hours post-dose ]
   Metformin Cmax in absence of PF-06865571
2. Metformin Cmax (in presence of PF-06865571) [ Time Frame: 0, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24, 48 hours post-dose ]
   Metformin Cmax in presence of PF-06865571
3. Area Under the Curve From Time Zero to Extrapolated Infinite Time (AUCinf) of Metformin (in absence of PF-06865571) [ Time Frame: 0, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24, 48 hours post-dose ]
   Metformin AUCinf in absence of PF-06865571
4. Metformin AUCinf (in presence of PF-06865571) [ Time Frame: 0, 0.5, 1, 2, 4, 6, 8, 10, 12, 16, 24, 48 hours post-dose ]
   Metformin AUCinf in presence of PF-06865571

Secondary Outcome Measures :

1. Number of Participants With Treatment Emergent Treatment-Related Adverse Events (AEs) [ Time Frame: Baseline up to 35 days after last dose of study medication ]
   Treatment-related AE are any untoward medical occurrence attributed to study drug in a participant who received study drug. Treatment-emergent are events between first dose of study drug and up to 35 days after last dose that were absent before treatment or that worsened relative to pretreatment state. Relatedness to study drug is assessed either yes or no by the investigator. Participants with multiple occurrences of an AE within a category are counted once within the category.
2. Number of Participants With Laboratory Abnormalities [ Time Frame: Baseline up to 35 days after last dose of study medication ]
   The following parameters were analyzed for laboratory examination: hematology (hemoglobin, hematocrit, red blood cell count, platelet count, white blood cell count, total neutrophils, eosinophils, monocytes, basophils, lymphocytes); blood chemistry (blood urea nitrogen, creatinine, glucose, calcium, sodium, potassium, chloride, total bicarbonate, aspartate aminotransferase, alanine aminotransferase, total bilirubin, alkaline phosphatase, uric acid albumin, total protein); urinalysis (decimal logarithm of reciprocal of hydrogen ion activity [pH], glucose, protein, blood, ketones, microscopy [if urine tested positive for blood or protein]).
3. Number of Participants With Clinically Significant Change From Baseline in Vital Signs [ Time Frame: 0 and 48 hours (h) post-dose ]
   the following parameters were analyzed for examination of vital signs: systolic and diastolic blood pressure and pulse rate.
4. Number of Participants With Change From Baseline in Electrocardiogram (ECG) Findings [ Time Frame: 0 and 48 h post-dose ]
   Absolute values and changes from baseline for ECG parameters

Eligibility Criteria

• Ages Eligible for Study: 18 Years to 55 Years (Adult)
• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: Yes

Criteria

Inclusion Criteria:

1. Healthy female subjects of nonchildbearing potential and/or male subjects who, at the time of screening, are between the ages of 18 and 55 years.
2. Body mass index of 17.5 to 30.5 kg/m2; and a total body weight >50 kg (110 lb).
3. Evidence of a personally signed and dated informed consent document.
4. Subjects who are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, and other study procedures.

Exclusion Criteria:

1. 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).
2. Any condition possibly affecting drug absorption (eg, gastrectomy).
3. A positive urine drug test.
4. History of regular alcohol consumption exceeding 14 drinks/week for female subjects or 21 drinks/week for male subjects.
5. 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).
6. Screening supine BP >=140 mm Hg (systolic) or >=90 mm Hg (diastolic), following at least 5 minutes of supine rest.
7. Screening supine 12-lead ECG demonstrating a corrected QT (QTc) interval >450 msec or a QRS interval >120 msec.

8. Subjects with ANY of the following abnormalities in clinical laboratory tests at screening, as assessed by the study-specific laboratory and confirmed by a single repeat test, if deemed necessary:

   • Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) level >=1.25× upper limit of normal (ULN);
   • Total bilirubin level >=1.5× ULN; subjects with a history of Gilbert's syndrome may have direct bilirubin measured and would be eligible for this study provided the direct bilirubin level is <=ULN.
9. Fertile male subjects who are unwilling or unable to use a highly effective method of contraception as outlined in this protocol for the duration of the study and through the follow up contact, or have female partners that are pregnant.
10. Use of prescription or nonprescription drugs and dietary supplements within 7 days or 5 half-lives (whichever is longer) prior to the first dose of investigational product.
11. Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more within 60 days prior to dosing.
12. History of sensitivity to heparin or heparin-induced thrombocytopenia only if heparin is used to flush any intravenous catheters in the study.
13. History of human immunodeficiency virus (HIV), hepatitis B, or hepatitis C; positive testing at the screening visit for HIV, hepatitis B surface antigen (HepBsAg), hepatitis B core antibody (HepBcAb), or hepatitis C antibody (HCVAb). While not part of the tests assessed in this study, subjects with a positive hepatitis B surface antibody (HepBsAb) result due to vaccination are deemed eligible.
14. Unwilling or unable to comply with the criteria in the Lifestyle Requirements section of this protocol.
15. Subjects who are 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 subjects who are Pfizer employees, including their family members, directly involved in the conduct of the study.
16. 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.
17. Subjects who have participated in prior studies with PF-06865571.
