Crohn's Disease
About this trial
This is an interventional basic science trial for Crohn's Disease focused on measuring GSK1605786, relative bioavailability, CCR9 receptor antagonist
Eligibility Criteria
Inclusion Criteria:
- AST, ALT, alkaline phosphatase and bilirubin ≤ 1.5xULN (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
- Healthy as determined by a responsible and experienced physician, based on a medical evaluation including medical history, physical examination, laboratory tests and ECG. 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 factors and will not interfere with the study procedures.
- Male or female between 18 and 55 years of age inclusive, at the time of signing the informed consent.
A female subject is eligible to participate if she is of:
- Non-childbearing potential defined as pre-menopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 months of spontaneous amenorrhea [in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 MlU/ml and estradiol < 40 pg/ml (<140 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 contraception methods in Section 8.1 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 enrollment. For most forms of HRT, at least 2-4 weeks will elapse between the cessation of therapy and the blood draw; this interval depends on the type and dosage of HRT. Following confirmation of their post-menopausal status, they can resume use of HRT during the study without use of a contraceptive method.
- Child-bearing potential and agrees to use one of the contraception methods listed in Section 8.1 for an appropriate period of time (as determined by the product label or investigator) prior to the start of dosing to sufficiently minimize the risk of pregnancy at that point. Female subjects must agree to use contraception until 4 weeks post-last dose.
- Male subjects must agree to use one of the contraception methods listed in Section 8.1. This criterion must be followed from the time of the first dose of study medication until 4 weeks post-last dose.
- Body weight ≥ 50 kg (110lbs) for men and ≥45 kg (99 lbs) for women, and BMI within the range 18.5 - 31 kg/m2 (inclusive).
- Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
- 12-lead ECG without any clinically significant abnormality as judged by the Investigator, and average QTcB or QTcF < 450 msec or QTc < 480 msec in subjects with Bundle Branch Block.
- Able to complete all study procedures and planned treatment periods.
Exclusion Criteria:
- A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening
- Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
- Known celiac disease and positive serologic testing for anti-tTG antibodies (required to screen for undiagnosed celiac disease)
- A positive pre-study drug/alcohol screen.
- A positive test for HIV antibody.
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.
- Unwilling to abstain from alcohol for 48 hours prior to screening, and 48 hours prior to the start of dosing until collection of the final pharmacokinetic sample during each treatment 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.
- 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.
- History of sensitivity to the study medication, 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.
- Where participation in the study would result in donation of blood or blood products in excess of 500 mL within a 56 day period.
- Pregnant females as determined by positive serum hCG test at screening or urine hCG test prior to dosing.
- Lactating females.
- The subject's systolic blood pressure is outside the range of 90-140mmHg, or diastolic blood pressure is outside the range of 45-90mmHg, or heart rate is outside the range of 50-100bpm for female subjects or 45-100 bpm for male subjects at Screening and pre-dose on Day 1.
- Unwillingness or inability to follow the procedures outlined in the protocol.
- Subject is mentally or legally incapacitated.
- Subject with a medical condition which in the opinion of the investigator and GSK Medical Monitor makes them unsuitable for the study.
- History of sensitivity to heparin or heparin-induced thrombocytopenia.
- History of regular use of tobacco- or nicotine-containing products within 6 months prior to screening and unwilling to remain abstinent from tobacco or nicotine containing products for the duration of the study.
- Consumption of red wine, seville oranges, grapefruit or grapefruit juice, pomegranate, and/or pummelos, exotic citrus fruits, grapefruit hybrids or fruit juices from 7 days prior to the first dose of study medication.
