Trial overview
Official title: An Open-Label, Non-Randomized, Two-Period, Cross-Over, Mass Balance Study to Investigate the Recovery, Excretion and Pharmacokinetics of 14C-GSK2140944 Administered as a Single Intravenous and Single Oral Dose to Healthy Adult Male Subjects (BTZ115774)
Trial description: This is an open-label, non-randomized, two-period, cross-over, mass balance study that will evaluate the recovery, excretion, and pharmacokinetics of a single intravenous (IV) dose of [14C]-GSK2140944 (Period 1) and a single oral dose of [14C]-GSK2140944 ( Period 2) in 6 healthy male subjects. The results from this study will aid in the design of future clinical pharmacology studies such as the thorough corrected QT interval study, special population studies (renal, hepatic, critically ill patients), potential drug interaction studies, and will help to establish safe and efficacious intravenous and oral dosing regimens.

Accepts healthy volunteers
Yes
- A subject will be eligible for inclusion in this study only if all of the following criteria apply:
- Male aged between 30 and 55 years of age inclusive, at the time of signing the informed consent.
- Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
- History of regular alcohol consumption within 6 months of the study defined as: An average weekly intake of >21 units for males. One unit is equivalent to 8 g of alcohol: a half-pint (approximately 240 ml) of beer, 1 glass (125 milliliter [mL]) of wine or 1 (25 mL) measure of spirits.
Inclusion and exclusion criteria
Inclusion criteria:
- A subject will be eligible for inclusion in this study only if all of the following criteria apply:
- Male aged between 30 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, vital signs, laboratory tests and cardiac monitoring.
- A subject with a clinical abnormality or laboratory parameter 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 and Body Mass Index within the range 19– 31 kilogram per square meter (inclusive).
- Alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and bilirubin <=1.5xupper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
- A history of regular bowel movements (averaging one or more bowel movements per day).
- Male subjects with female partners of child-bearing potential must agree to use one of the contraception methods listed in Protocol. This criterion must be followed from the time of the first dose of study medication until four months after the last dose.
- Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
Exclusion criteria:
- Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
- History of regular alcohol consumption within 6 months of the study defined as: An average weekly intake of >21 units for males. One unit is equivalent to 8 g of alcohol: a half-pint (approximately 240 ml) of beer, 1 glass (125 milliliter [mL]) of wine or 1 (25 mL) measure of spirits.
- History of sensitivity to heparin or heparin-induced thrombocytopenia.
- History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or GSK Medical Monitor, contraindicates their participation.

- History of sensitivity to quinolones including photosensitivity and tendon rupture.
- A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening or positive test for Human Immunodeficiency Virus (HIV) antibody.

- A serum creatinine value between screening and Day -1 visit that is increased by more than 0.2 milligrams per decilitre (or 15.25 micromole per liter) changes.
- Urinary cotinine levels indicative of smoking or history or regular use of tobacco- or nicotine-containing products within 6 months prior to screening.
- A positive pre-study drug/alcohol screen.
- Exclusion criteria for screening and baseline ECG (a single repeat is allowed for eligibility determination): Heart rate <40 and >100 beats per minute; PR Interval <120 and >220 milliseconds (msec); QRS duration <70 and >100 msec; QT duration corrected for heart rate by Bazett’s formula (QTcB) or QT duration corrected for heart rate by Fridericia’s formula (QTcF) interval >450 msec; 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], Wolf Parkinson White [WPW] syndrome), sinus pauses> 3 seconds, non-sustained or sustained ventricular tachycardia (>=3 consecutive ventricular ectopic beats) or any significant arrhythmia which, in the opinion of the principal investigator and GSK medical monitor, will interfere with the safety of the individual subject.
- Where participation in the study would result in donation of blood or blood products in excess of 500 millilitre (mL) within a 56 day period.
- The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer).
- Exposure to more than four new chemical entities within 12 months prior to the first dosing day. Subjects who have received a total body radiation dose of greater than 5.0 millisievert (upper limit of World Health Organization category II) or exposure to significant radiation (e.g. serial x-ray or CT scans, barium meal etc) in the 12 months prior to this study.
- Any condition that could interfere with the accurate assessment and recovery of radioactivity [14C].
- Participation in a clinical trial involving administration of 14C-labelled compound(s) within the last 12 months.
- Unwillingness to commit to avoid excessive exposure to sunlight (or exposure whilst on a tanning bed) which would cause a sunburn reaction from first dose up to and including discharge.
