Effects of GSK1278863A on Pulmonary Artery Pressure in Healthy Volunteers

Completed · Phase 1 · Has a placebo group

Conditions studied: Anaemia

In brief

This protocol is designed to explore whether short-term therapy with GSK1278863 affects PASP under normoxic and hypoxic conditions in healthy volunteers. Healthy subjects will be evaluated using echocardiography to estimate PASP based on the velocity of the tricuspid regurgitant jet. Resting PASP will be assessed under normoxic (room air) conditions, as well as after 30 minutes' exposure to 15% O2 before, during, and after short-term treatment with GSK1278863.

Who can join

Age: 18 and older, up to 55. Sex: male. Healthy volunteers: accepted.

You may qualify if…

• AST, ALT, alkaline phosphatase and bilirubin less than and equal to 1.5xULN (isolated bilirubin greater than 1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin less than 35%).
• Healthy as determined by a responsible and experienced physician, based on a medical evaluation including [medical history, physical examination and laboratory tests]. 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 and the GSK Medical Monitor agree that the finding is unlikely to introduce additional risk and will not interfere with the study procedures.
• A hemoglobin value at screening between 13.5- 16 g/dL.
• Male subjects between 18 and 55 years of age inclusive, at the time of signing the informed consent.
• Male subjects with female partners of child-bearing potential must agree to use one of the contraception methods listed in the protocol. This criterion must be followed from the time of the first dose of study medication until the follow-up visit.
• BMII less than and equal to 32 kg/m2
• Single QTcB or QTcF less than 450 msec
• Screening echocardiogram of at least good quality, without clinically significant abnormalities, and with mild-moderate tricuspid regurgitation sufficient for the reliable estimation of PASP, as determined by the echocardiography core laboratory or responsible cardiologist.
• Screening PASP within the normal range under normoxic conditions.

You may not qualify if…

• A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result.
• Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
• A positive pre-study drug/alcohol screen.
• Any history of IV drug abuse.
• A positive test for HIV antibody.
• History of regular alcohol consumption within 6 months of the study defined as: an average weekly intake of greater than 14 drinks for males or greater than 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.
• 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.
• Use of prescription or non-prescription drugs, including vitamins, herbal and dietary supplements (including St John's Wort) 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 medication, unless in the opinion of the Investigator and GSK Medical Monitor the medication will not interfere with the study procedures or compromise subject safety.
• Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period.
• Unwillingness or inability to follow the procedures outlined in the protocol.
• Urinary cotinine levels indicative of smoking or history or regular use of tobacco- or nicotine-containing products within 6 months prior to screening.
• Strong family history of malignancy.
• Subjects with sickle cell trait.
• History of pulmonary hypertension
