Description
Inclusion Criteria:
- Subjects who are between 20 and 45 years and of age, inclusive at the time of signing the informed consent form.
- Japanese, defined as being born in Japan, having four ethnic Japanese grandparents, holding a Japanese passport or identity papers and being able to speak Japanese, and that lifestyle including diet has not changed significantly since leaving Japan. Japanese subjects should also have lived outside Japan for less than 10 years.
- Caucasian subjects as defined as an individual having four grandparents who are all descendants of the original peoples of Europe.
- 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.
- A subject with a clinical abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included only if the investigator in consultation with the medical monitor agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.
- Body weight >=43 kilograms (kg) and body mass index (BMI) within the range 17-29.9 kilogram per square meter (kg/m^2) (inclusive).
- Female subjects- A female subject is eligible to participate if she is: A female of non-productive potential secondary to a personal history of a hysterectomy or tubal sterilization procedure.
A female of reproductive potential who is not pregnant (as confirmed by a negative urine or serum human chorionic gonadotropin [hCG] test), not lactating, and agrees to follow one of the options listed in protocol. Contraception requirement for female subjects from 28 days prior to the first dose of study treatment and until completion of the follow-up visit.
- 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 this protocol.
Exclusion Criteria:
- Alanine aminotransferase (ALT), alkaline phosphatase and bilirubin >1.5x upper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
- Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones)
- QT duration corrected (QTc) >450 milliseconds (msec) NOTES: The QTc is the QT interval corrected for heart rate according to Bazett's formula (QTcB), QT duration corrected for heart rate by Fridericia's formula (QTcF), and/or another method, machine-read or manually over-read.
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.
- 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 investigational product until completion of the follow-up visit, unless in the opinion of the investigator and GlaxoSmithKline (GSK) medical monitor the medication will not interfere with the study.
- History of regular alcohol consumption within 6 months of the study defined as: An average weekly intake of >7 drinks. One drink is equivalent to 12 grams (g) of alcohol: 12 ounces (360 milliliter [mL]) of beer, 5 ounces (150 mL) of wine or 1.5 ounces (45 mL) of 80 proof distilled spirits.
- History of drug abuse or dependence within 6 months of the study.
- 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 medical monitor, contraindicates their participation.
- Presence of hepatitis B surface antigen (HBsAg), positive hepatitis C antibody test result at screening or within 3 months prior to first dose of study treatment.
- A positive pre-study drug/alcohol screen.
- A positive test for human immunodeficiency virus (HIV) antibody.
- Where participation in the study would result in donation of blood or blood products in excess of 500 mL within 56 days.
- 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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Cohort 1: Retosiban/placebo
Each subject in cohort 1 will receive an intravenous (IV) bolus infusion of 6 milligrams (mg) retosiban or placebo over 5 minutes, followed by a continuous infusion of 6 milligram per hour (mg/h) retosiban or placebo for 24 h.
At 24 h of dosing, an additional 6 mg retosiban or placebo will be administered over 5 minutes followed by a 12 mg/h infusion over the next 24 h, for a total time of infusion of 48 h.
Subjects administered with placebo will receive an equal volume of normal saline as an IV bolus as well as an equal rate of continuous infusion of normal saline as of retosiban.
|
Retosiban will be supplied as clear, colorless IV solution for infusion in 5 mL vial with a unit dose strength of 15 milligrams per milliliter (mg/mL) (each 5 mL vial contains 75 mg retosiban), dosed at up to 300 mg over 48 h infusion
Placebo will be supplied as a clear, colorless IV solution for infusion with a unit dose strength of 0.9% sodium chloride (NaCl) normal saline
|
Experimental: Cohort 2: Retosiban
Each subject in cohort 2 will receive a bolus infusion of 6 mg retosiban over 5 minutes, followed by a continuous infusion of 6 mg/h retosiban for 24 h.
At 24 h of dosing, an additional 6 mg retosiban will be administered over 5 minutes followed by a 12 mg/h infusion over the next 24 h, for a total time of infusion of 48 h.
|
Retosiban will be supplied as clear, colorless IV solution for infusion in 5 mL vial with a unit dose strength of 15 milligrams per milliliter (mg/mL) (each 5 mL vial contains 75 mg retosiban), dosed at up to 300 mg over 48 h infusion
