Key inclusion criteria
- Healthy as determined by a Physician Responsible, based on a medical evaluation
including history, physical examination, laboratory tests, cardiac monitoring. A
subject with a clinical abnormality or laboratory variables outside the reference
range for the population being studied, with the exception of liver transaminases,
troponin I and TSH, may be included only if the Investigator considers that the
finding will not introduce additional risk factors and will not interfere with the
study procedures. Please note that subjects should have liver transaminases, troponin
I and TSH values within the range specified in the exclusion criteria below.
- Male or female between 18 and 65 years of age inclusive.
- 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 and confirmed by screening follicle stimulating hormone
(FSH) > 40 MlU/ml and estradiol < 40 pg/ml or <140 pmol/L.. Females on hormone
replacement therapy (HRT) must discontinue HRT and their post-menopausal status
confirmed as per above tests 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 are not allowed to use HRT during the study.
- Child-bearing potential and agrees to use one of the contraception methods as per
protocol 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 at
least 7 days after the last dose of study medication.
- Male subjects must agree to use one of the contraception methods as per protocol. This
criterion must be followed from the time of the first dose of study medication until
at least 7 days post last dose.
- No co-morbid Psychiatric Disorders as defined using the Mini International
Neuropsychiatric Interview (M.I.N.I) scale.
- Normal neurological examination performed by the study neurologist
- A 12-lead ECG at screening showing no abnormalities that in the opinion of the
Principal Investigator will compromise safety in this study.
- Body weight >/ 50 kg and BMI within the range 19.0 - 29.9 kg/m2 (inclusive).
- Capable of giving written informed consent, which includes compliance with the
requirements and restrictions listed in the consent form.
- The subject must be able to read, comprehend and record information.
- A signed and dated written informed consent is obtained from the subject
- The subject is available to complete the study
Both males and females
Can healthy volunteers participate?
Key exclusion criteria
- As a result of any of the medical interview, physical examination or screening
investigations the Physician Responsible considers the subject unfit for the study.
- The subject or his/her family has a history of a drug or other allergy which in the
opinion of the Physician Responsible contraindicates the participation in the study.
- Subjects with an unstable medical disorder or a disorder that would likely interfere
with the action, absorption, distribution, metabolism or excretion of GW823296, may
pose a safety concern, or interfere with accurate assessment of safety.
- The subject has a current or recent (within six months) documented gastrointestinal
disease; a history of malabsorption, oesophageal reflux, or irritable bowel syndrome;
frequent (more than once a week) occurrence of heartburn, or any surgical intervention
(e.g. cholecystectomy) which would be expected to influence the absorption of drugs.
- History of psychiatric illness
- Any history of a clinically significant abnormality of the neurological system
(including dementia and other cognitive disorders or significant head injury) or any
history of seizure (excluding febrile seizure).
- 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 any
drug(whichever is longer)
- The subject has screening alanine aminotransferase (ALT) or aspartate aminotransferase
(AST) >1.5x upper limit of the normal range (ULN); testing may be repeated once to see
if value returns to within acceptance range but any such laboratory abnormality must
be resolved by the baseline visit.
- Subjects with a troponin I value >0.03 ng/mL at screening are not eligible. Testing
may not be repeated. The subject should be referred to the treating physician for
further evaluation, as appropriate.
- Subjects with a TSH value above the upper limit of the normal range (ULN) at screening
are not eligible. The subject should be referred to the treating physician for further
evaluation, as appropriate. Testing may be repeated once to see whether the value
returns to within normal range but such abnormality must be resolved before the
- Subjects with a history of myopathy or rhabdomyolysis
- The subject is unable to abstain from strenuous physical activity for 72 hours prior
to screening, for 72 hours prior first dosing until the last PK sample has been
collected, and for 72 hours prior to the follow-up visit.
- The subject has donated a unit of blood (450 mL) within the previous 60 days or
intends to donate in the month after completing the study
- Subjects with a history of eye disease (excluding moderate myopia) or clinically
relevant eye examination finding, which in the opinion of the study ophthalmologist
contraindicates their participation in the study
- The subjects is currently taking regular (or a course of) medication whether
prescribed or not, including vitamins and herbal remedies, such as St John's Wort. Any
concurrent medication will not be permitted for 48 hours before admission to the CPRU
until the end of the study period (follow-up visit), unless in the opinion of the
Investigator and the GSK Medical Monitor the medication will not interfere with the
study procedures or compromise subject safety.
- History of regular alcohol consumption within 6 months of the study defined as:
An average weekly intake of greater than 21 units or an average daily intake of greater
than 3 units (males), or an average weekly intake of greater than 14 units or an average
daily intake of greater than 2 units (females).
[NOTE: 1 unit = 240mL beer, 90mL wine, or 30mL hard liquor]

prior to screening or a positive urine cotinine test result indicative of smoking at
- A positive Hepatitis B surface antigen or positive Hepatitis C antibody result within
3 months of screening.
- The subject has tested positive for HIV-1/2.
- The subject has a past history of drug/alcohol abuse or has a positive pre-study
drug/alcohol screen. A minimum list of drugs that will be screened for include
Amphetamines, Barbiturates, Cocaine, Opiates, Cannabinoids, Benzodiazepines and

contraindicates their participation.
