Show details

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, inclusive. Healthy is
defined as no clinically relevant abnormalities identified by a detailed medical
history, full physical examination, including BP and pulse rate measurement, 12-lead

ECG, or clinical laboratory tests. Female subjects of nonchildbearing potential must
meet at least 1 of the following criteria:

for at least 12 consecutive months with no alternative pathological or
physiological cause; status may be confirmed with a serum follicle-stimulating
hormone (FSH) level confirming the postmenopausal state;

2. Have undergone a documented hysterectomy and/or bilateral oophorectomy;

3. Have medically confirmed ovarian failure. All other female subjects (including
female subjects with tubal ligations) are considered to be of childbearing
potential.

2. Body mass index (BMI) 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 indicating that
the subject has been informed of all pertinent aspects of the study.

4. Subjects who are willing and able to comply with all scheduled visits, treatment plan,
laboratory tests, and other study procedures.

Exclusion criteria
The factors, or reasons, that prevent a person from participating in a clinical study.
Show details

1. Evidence or history of clinically significant hematological, renal, endocrine,
pulmonary, gastrointestinal, cardiovascular, hepatic (including alcoholic liver
disease, nonalcoholic steatohepatitis (NASH), autoimmune hepatitis, and hereditary

screening, as assessed by the study-specific laboratory and confirmed by a single
repeat test, if deemed necessary:

Aspartate aminotransferase (AST)/serum glutamic oxaloacetic transminase (SGOT) or
alanine aminotransferase (ALT)/serum glutamic pyruvic transminase (SGPT) 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.

of nonprescription medications that are not believed to affect subject safety or the
overall results of the study may be permitted on a case-by-case basis following
approval by the sponsor. Herbal supplements and hormone replacement therapy must have
been discontinued at least 28 days prior to the first dose of investigational product.

17. Use of tobacco- or nicotine- containing products in excess of the equivalent of 5
cigarettes per day.

18. Blood donation (excluding plasma donations) of approximately 1 pint (500 mL) or more
within 60 days prior to dosing.

19. History of hypersensitivity, allergy, severe adverse drug reaction or intolerance to
quinolone antibiotics, including moxifloxacin.

20. History of human immunodeficiency virus (HIV), hepatitis B, or hepatitis C; positive
testing for HIV, hepatitis B surface antigen (HepBsAg), hepatitis B core antibody
(HepBcAb), or hepatitis C antibody (HCVAb). As an exception, a positive hepatitis B
surface antibody (HepBsAb) finding as a result of subject vaccination is permissible.

21. Unwilling or unable to comply with the criteria in the Lifestyle Requirements section
of this protocol.

22. 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.

23. 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.

A Study To Determine The Effect Of Single-dose PF-04965842 On QTc Interval In Healthy Volunteers Compared With Placebo and Moxifloxacin
A Phase 1, Randomized, Placebo-and Positive-controlled Crossover Study To Determine The Effect Of Single-dose Pf-04965842 On Qtc Interval In Healthy Volunteers

This is a Phase 1, single-dose, randomized, 3-treatment, 3-period cross-over, sponsor-open, placebo-and positive-controlled trial to be conducted in approximately 36 adult healthy volunteers. There will be 3 crossover treatments: PF-04965842 600 mg (A), placebo (B) and moxifloxacin 400 mg (C). Treatment assignments to PF-04965842 and placebo will be blinded to the subjects, investigator and Clinical Research Unit (CRU) staff (except pharmacist) but open to the sponsor. Moxifloxacin administration will be unblinded. Dosing in each of the 3 treatment periods will be separated by a washout period of at least 5 days

Screening evaluation will occur within the 28 days prior to dosing in the first treatment period. During each treatment period, eligible subjects who meet the entry criteria will be admitted on Day -1, prior to treatment administration on Day 1, and will reside in the CRU until completion of protocol assessments on Day 2. There will be a washout of at least 5 days between dose administrations in consecutive crossover treatment periods. After completion of the 3 study periods or upon withdrawal from the study, subjects will return for a follow-up visit approximately 7-14 days following last dose of investigational product. Further follow-up contact will be made at least 28 calendar days and up to 35 calendar days after the last administration of the investigational product to capture any potential AEs and concomitant treatments, and to confirm appropriate contraception usage, contact with the subject may be done via phone. For each subject, the duration of participation from Day 1 admission to follow-up visit will be approximately 10 weeks. The follow-up call will occur up to 4 weeks after the follow-up visit.

In each treatment period, the subject will be admitted to the CRU the day prior to dosing. Genotyping samples for CYP2C19 and CYP2C9 will be collected pre-dose in Period 1 only. The subject will receive a single dose of the assigned trial medication in the morning of Day 1. Triplicate 12-lead ECG measurements (approximately 2 minutes apart) will be performed on Days 1 and 2 of each treatment period as follows: -1, -0.5 and 0 hours pre-dose and at 0.25, 0.5, 1, 2, 3, 6, 12, and 24 hours post-dose. Blood samples will be collected following the 0 hour and post-dose ECG measurements at the same time-points to evaluate the PK of PF-04965842 and moxifloxacin (if needed). Clinical safety laboratory tests will be performed on Day -1 and at 24 hours on Day 2, and vital signs (supine pulse rate and BP) will be monitored pre-dose and at 2 and 6 hours post-dose on Day 1 and at 24 hours on Day 2. The subject will be discharged from the CRU after completing all trial procedures of the particular treatment period in the morning of Day 2 (24 hours post-dose).
