Placebo and Moxifloxacin Controlled Cardiac Conduction Study of GSK2140944 in Healthy Volunteers
A Phase I, Randomized, Double-Blinded, Placebo- and Moxifloxacin-Controlled, 4-Period Crossover Study to Evaluate the Effect of GSK2140944 on Cardiac Conduction as Assessed by 12-lead Electrocardiogram in Healthy Volunteers
This is Phase I, 4-period, randomized, active-and placebo-controlled, double-blind crossover, single-dose study to evaluate the effects of a therapeutic (1000 milligram [mg]) and supratherapeutic (1800 mg) dose of GSK2140944 with a positive control (moxifloxacin 400 mg) and placebo on the corrected QT interval (QTc) as assessed by continuous 12-lead Holter electrocardiograms (ECGs) in approximately 55 healthy volunteers.
All subjects will receive single doses of GSK2140944 1000 mg, GSK2140944 1800 mg, moxifloxacin 400 mg, and placebo in a randomized sequence. A double-dummy approach will be used to maintain blinding. Thus, on each dosing day, moxifloxacin or moxifloxacin placebo and GSK2140944 or placebo will be administered.
Subjects will be screened within 30 days prior to entry to the clinic. Subjects will report to the clinical unit on Day -2 of Period 1 and on Day -1 in subsequent periods. Subjects will remain confined until check out procedures have been completed on Day 3 (5 days confinement in Period 1 and 4 days in the following 3 periods). There will be a washout of at least 7 days between doses. The follow-up visit will occur 7-10 days after the final dose. Total duration of the study (from screening to the follow-up visit) will be approximately 60 days.

Inclusion Criteria:
- Male or female between 18 and 55 years of age, inclusive, at the time of signing the informed consent
- Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring. A subject with a clinical abnormality or laboratory parameters outside the reference range for the population being studied may be included only if the investigator feels and documents that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
- Body weight >= 50 kilogram (kg) and body mass index within the range 19 to 31 kilogram / square meter (kg/m^2) (inclusive).
- A female subject is eligible to participate if she is not pregnant (as confirmed by a negative serum beta-human chorionic gonadotrophin test), not lactating, and at least one of the following conditions applies:
- Nonreproductive potential defined as:
- Premenopausal females with one of the following: Documented tubal ligation, documented hysteroscopic tubal occlusion procedure with follow-up confirmation of bilateral tubal occlusion, hysterectomy, documented bilateral oophorectomy.
- Postmenopausal defined as 12 months of spontaneous amenorrhea. To confirm postmenopausal status, a blood sample for simultaneous follicle-stimulating hormone (FSH) >40 milli-international units per mililiter (mlU/mL) and estradiol <40 picogram/milliliter (pg/mL) (<147 picomole/liter [pmol/L]) is confirmatory. Females on hormone replacement therapy (HRT) and whose menopausal status is in doubt will be required to use one of the highly effective contraception methods if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status prior to study enrolment.
- Reproductive potential and agrees to follow one of the options listed below in the GSK Modified List of Highly Effective Methods for Avoiding Pregnancy in Females of Reproductive Potential (FRP) requirements from 30 days prior to the first dose of study drug and until at least 7 days after the last dose of study drug and completion of the follow-up visit.
- This list does not apply to FRP with same sex partners, when this is their preferred and usual lifestyle or for subjects who are and will continue to be abstinent from penile-vaginal intercourse on a long-term and persistent basis.
- Contraceptive subdermal implant that meets the standard operating procedure (SOP) effectiveness criteria including a <1% rate of failure per year, as stated in the product label, intrauterine device or intrauterine system that meets the SOP effectiveness criteria including a <1% rate of failure per year, as stated in the product label, oral contraceptive, either combined or progestogen alone, injectable progestogen, contraceptive vaginal ring, percutaneous contraceptive patches, male partner sterilization with documentation of azoospermia prior to the female subject's entry into the study, and this male is the sole partner for that subject.
- These allowed methods of contraception are only effective when used consistently, correctly and in accordance with the product label. The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception.
- Capable of giving signed informed consent as described in protocol, which includes compliance with the requirements and restrictions listed in the consent form and in the protocol
- Alanine aminotransferase (ALT) and bilirubin <1.5 × upper limit of normal range (ULN). Isolated bilirubin >1.5 × ULN is acceptable if bilirubin is fractionated and direct bilirubin <35%. One repeat test to confirm result is acceptable.
- Serum potassium, calcium, and magnesium laboratory parameters within normal limits at screening and check-in.
Exclusion Criteria:
- History/evidence of any arrhythmia (for example, second- or third-degree heart block, atrial fibrillation, supraventricular tachycardia, symptomatic sinus bradycardia, junctional rhythm) or clinically significant cardiac disease or procedure (mitral valve regurgitation, heart murmur, angina/ischemia, congenital heart abnormalities, coronary artery bypass grafting surgery, or percutaneous transluminal coronary angioplasty). A history of additional risk factors for torsades de pointes (e.g., heart failure, hypokalemia, and family history of long QT syndrome).
- Current or chronic history of liver disease or known hepatic or biliary abnormalities (with the exception of Gilbert syndrome or asymptomatic gallstones).
- Any clinically significant CNS (e.g., seizures), cardiac, pulmonary, metabolic, renal, hepatic, or GI conditions or history of such conditions that, in the opinion of the investigator, may place the subject at an unacceptable risk as a participant in this trial or may interfere with the absorption, distribution, metabolism, or excretion of drugs.

- Evidence of previous myocardial infarction (does not include ST-segment changes associated with repolarization).
- Any conduction abnormality (including but not specific to left or right complete bundle branch block, atrioventricular block [second degree or higher], Wolff-Parkinson-White syndrome), sinus pauses >3 seconds, non-sustained or sustained ventricular tachycardia (>3 consecutive ventricular ectopic beats), or any significant arrhythmia that, in the opinion of the investigator and GSK medical monitor, will interfere with the safety of the individual subject.
- An abnormal finding of clinical significance in the arrhythmia detection Holter performed on Day -2, which in the view of the investigator would compromise subject safety or interfere with study procedures or assessments will be excluded from the study. Full disclosures will be reviewed in detail and the review maintained as part of the subject's source documents. Analysis of the Holter recordings will consider the following:
- Heart rate (significant brady- or tachycardia, based on investigator's judgment)
- Reports of symptomatic arrhythmia (except isolated extrasystoles)
- Normal and aberrant beats
- Number of supraventricular contractions, premature atrial contractions, premature ventricular contractions, couplets, triplets, and ventricular tachycardias
- Atrioventricular conduction defects
