简要总结
The rationale of this study is to assess whether or not food affects the absorption of GW273225 into the blood of healthy male and female volunteers in order to evaluate whether or not this drug should be given at a certain time relative to the consumption of food.

入选标准
- •Healthy male or female subjects aged 18-55 years, inclusive.
- •Body weight 45-100kg and BMI 19-29.9 kg/m2 inclusive.
- •Post-menopausal females (longer than two years). Or Pre-menopausal females with a documented hysterectomy and/or bilateral oophorectomy, the latter only when the reproductive status of the woman has been confirmed by follow up hormone level assessment.
- •Female subjects of child bearing potential willing to participate commit to use a double-barrier method of contraception. One of the following methods is acceptable as the sole method of contraception if there is indisputable data that it is >99% effective, otherwise it should be used with a barrier method (condom or occlusive cap (diaphragm or cervical/vault caps) used with spermicidal foam/gel/film/cream/suppository): Documented tubal ligation. Documented placement of an IUD or IUS. Male partner sterilisation prior to the female subject's entry into the study and is the sole partner for that female subject.
- •No abnormality on relevant clinical examination or clinical chemistry or haematology examination at the pre-study medical examination.
- •A normal 12-lead ECG at the pre-study medical examination
- •A negative pre-study Hepatitis B, Hepatitis C, and HIV antibody result at screening.
- •A negative pre-study urine drug screen.
- •A negative screen for alcohol.
- •Subjects must smoke <10 cigarettes per day.
- •The subject is able to understand and comply with the study and it's restrictions.
排除标准
- •An unwillingness of the male subject to use a double-barrier method of contraception.
- •Female subject is pregnant or lactating.
- •Female subjects using hormonal contraceptive precautions including progesterone-coated IUD and oral contraceptives.
- •Female subjects using hormonal replacement therapy.
- •History of alcohol/drug abuse or dependence within 12 months of the study
- •The subject has a positive pre-study urine drug/ urine alcohol screen. A minimum list of drugs that will be screened for include Amphetamines, Barbiturates, Cocaine, Opiates, Cannabinoids and Benzodiazepines.
- •A positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening
- •Weekly alcohol intake of more than 21 units or an average daily intake of greater than three units (for male subjects) or weekly alcohol intake more than 14 units or an average daily intake of greater than two units (for female subjects).
- •The subject has participated in a clinical trial and has received a drug or a new chemical entity within 30 days or 5 half-lives, or twice the duration of the biological effect of any drug(whichever is longer) prior to the first dose of current study medication.
- •Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
- •Use of prescription or non-prescription drugs 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.
- •History of sensitivity to any of the study medications, or components thereof.
- •Where participation in study would result in donation of blood in excess of 500 mL within a 56 day period.
- •History of hypersensitivity to lamotrigine or GW
- •History of clinically relevant skin rashes and allergies that, in the opinion of the investigator, might interfere with the conduct of the study.
- •Subject has current or past history of seizure disorder or brain injury, or any condition which, in the opinion of the investigator, predisposes to seizure; subject treated with other medications or treatment regimens that lower seizure threshold; subject undergoing abrupt discontinuation of alcohol or sedatives (including benzodiazepines)
研究组 & 干预措施
Sequence AB
Experimental
Subjects will be randomized to sequence AB, where A represents fasted state and B represents fed state. Subjects will be administered a single oral dose of GW273225 50 milligrams (mg) in the fasted state in dosing period 1. The subjects will receive a single oral dose of GW273225 50 mg immediately after a high fat breakfast in dosing period 2. There will be at least 21 days between doses for the fasted and fed treatment phases of the study.
