- Lead Sponsor
- GlaxoSmithKline
- Brief Summary

- Detailed Description
This is an open-label, parallel group, single-center study. The study design consists of a screening and a treatment period. A total of 42 (approximately 21 of each sex) non-smoking healthy volunteers aged 18 - 35, will be selected for treatment. Potential subjects will be assessed for exposure to ionizing radiation or working with cytotoxic chemicals, or who have cell cycle times that fall outside the range of 13 ± 1.5 hours or subjects with stable chromosomal rearrangements and/or abnormally high background chromosomal aberration frequencies. Approximately 30 subjects (10 per arm) are estimated to be needed for analysis.

- History or presence of cardio-or cerebrovascular disease; e.g., diabetes, hypertension, hyperlipidemia
- History or presence of congenital heart disease, cardiac arrhythmias requiring medication, or a clinically significant electrocardiogram abnormality that, in the investigator's opinion, contraindicates participation in the study
- History or evidence of any ischemic vascular diseases including: ischemic heart disease, ischemic abdominal syndromes, peripheral vascular disease or Raynaud's Syndrome, or sign/symptoms consistent with any of the above
- History or evidence of central nervous system pathology including stroke and/or transient ischemic attacks, epilepsy or structural brain lesions which lower the convulsive threshold, or has been treated with an antiepileptic drug for seizure control within 5 years prior to screening
