Trial overview
Official title: A Two-part Study to Evaluate the Pharmacokinetics, Safety, and Tolerability of a High, Single Oral Dose of GSK1278863 (Part A), and a Randomized, Single-blind, Placebo- and Positive-controlled, Four-way Crossover Study to Assess the Effect of Single, Oral Dose of GSK1278863 on Cardiac Repolarization (Part B) in Healthy Volunteers
Trial description: This study is being performed to comply with regulatory requirements that all new non-antiarrhythmic drugs must be assessed for potential effects on cardiac repolarization through electrocardiographic evaluation in a ‘Thorough QT/ Corrected QT interval (TQT)’ study. This will be a two part study, Part A will be an open-label, single oral dose study design in order to evaluate the pharmacokinetics, safety and tolerability of a 500 milligram (mg) dose of GSK1278863 and Part B will be a single-blind, randomized, placebo-controlled, single, oral dose, four-way crossover study design. Parts A and B will be conducted in healthy adult subjects with 12-lead electrocardiograms (ECGs), clinical laboratory safety tests, vital sign measurements, physical examinations, adverse event reports, and pharmacokinetic samples collected throughout the study.

Accepts healthy volunteers
Yes
- Subjects who are between 18 and 45 years and of age, inclusive at the time of signing the informed consent form
- Healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring obtained at the Screening visit.
- Hypertensive (diastolic BP >90 millimetres of mercury [mmHg] or systolic BP >140 mmHg) at screening
- A supine mean heart rate outside the range 50-100 beats per minute (bpm) at screening
Inclusion and exclusion criteria
Inclusion criteria:
- Subjects who are between 18 and 45 years and of age, inclusive at the time of signing the informed consent form
- Healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests and cardiac monitoring obtained at the Screening visit. The determination of clinical significance will be made by the Investigator and the GlaxoSmithKline (GSK) Medical Monitor and will require that the finding is unlikely to introduce additional risk factors or interfere with the study procedures, or the integrity of the study
- Hemoglobin values at screening greater than the lower limit of the laboratory reference range and less than or equal to 16.0 gram (g)/decilitre (dL) for males and less than or equal to 14.0 g/dL for females
- No significant abnormality on 12-lead ECG at screening, including the following specific requirements: Ventricular rate >= 40 beats per minute; PR interval <= 210milliseconds (msec); Q waves < 30msec (up to 50msec permitted in lead III only); QRS interval to be >= 60msec and < 120msec; The waveforms must enable the QT interval to be clearly defined; QTcF interval must be < 450msec.
- Body weight >= 50 kilograms (kg) and body mass index (BMI) within the range 19-29.9 kg/meter square (m^2) (inclusive).
- Female and Male: Female subject is eligible to participate if she is not pregnant (as confirmed by a negative serum human chorionic gonadotrophin [hCG] test), not lactating, and at least one of the following conditions applies:
- Non-reproductive potential defined as:
- Pre-menopausal 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 [in questionable cases, a blood sample with simultaneous follicle stimulating hormone (FSH) 23.0-116.3 International Units (IU)/Litre (L) and estradiol <=10 picograms (pg)/millilitre (mL) (or<=37 Picomoles (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 post-menopausal status prior to study enrolment
- Reproductive potential and agrees to follow the contraception requirement for female subjects from 30 days prior to the first dose of study treatment and until at least five terminal half-lives OR until any continuing pharmacologic effect has ended, whichever is longer after the last dose of study treatment and completion of the follow-up visit

Exclusion criteria:
- Hypertensive (diastolic BP >90 millimetres of mercury [mmHg] or systolic BP >140 mmHg) at screening

- The QTc is the QTcF interval
- The specific formula that will be used to determine eligibility and discontinuation for an individual subject should be determined prior to initiation of the study. In other words, several different formulae cannot be used to calculate the QTc for an individual subject and then the lowest QTc value used to include or discontinue the subject from the trial
- Serum calcium, magnesium or potassium levels outside the normal reference range
- History of deep vein thrombosis, stroke, transient ischemic attack, pulmonary embolism or other thrombosis related condition within the last five years
- History of myocardial infarction or acute coronary syndrome
- Subjects with a pre-existing condition interfering with normal gastrointestinal anatomy or motility, and/or hepatic function that could interfere with the absorption, metabolism, and/or excretion of GSK1278863. Examples of conditions that could interfere with normal gastrointestinal anatomy or motility include gastrointestinal bypass surgery, partial or total gastrectomy, small bowel resection, vagotomy, malabsorption, Crohn’s disease, ulcerative colitis, or celiac sprue
- Evidence of active peptic, duodenal or esophageal ulcer disease at Screening OR history of clinically significant gastrointestinal bleeding

- Subjects must abstain from taking prescription or non-prescription drugs (including vitamins and dietary or herbal supplements) except occasional usage of acetaminophen, within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study treatment until completion of the follow-up visit, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study medications)
- History of regular alcohol consumption within 6 months of the study defined as: An average weekly intake of >14 drinks for males or >7 drinks for females. One drink is equivalent to 12 g of alcohol: 12 ounces (360 mL) of beer, 5 ounces (150 mL) of wine or 1.5 ounces (45 mL) of 80 proof distilled spirits
- Urinary cotinine levels indicative of smoking or history or regular use of tobacco- or nicotine-containing products prior to screening
