- History of hepatitis B, a positive test for hepatitis B surface antigen, a history of
hepatitis C, a positive test for hepatitis C antibody, a history of HIV infection or
demonstration of HIV antibodies.

- Any evidence of organ dysfunction, or any clinically significant clinical laboratory
value which, in the opinion of the Investigator would jeopardize the safety of the
subject or impact on the validity of the study results, including a liver function
test (LFT) >1.5 x upper limit of normal (ULN).

- Those who may have difficulty abstaining from alcohol during the 48 hr prior to dose
administration and until completion of the Study Exit visit.

- History of, or current evidence of, abuse of alcohol or any drug substance, licit or
illicit, or positive urine drug screen for drugs of abuse.

- Difficulty in abstaining from any prescription medications for 14 days prior to dose
administration and for the duration of the study.

- Difficulty in abstaining from over-the-counter (OTC) medications or herbal supplements

exception of occasional analgesia, vitamin and other nutrient supplement use, at the
discretion of the Investigator).

administration in this study.

- Standard blood donation (usually 550 mL) within the 12-week period before dose

- Unusual dietary habits and excessive or unusual vitamin intakes.

- Vaccination or immunizations within 30 days of initial dose administration.

- Whilst there were no QT/QTc effects seen in the human volunteers at a dose of 20 mg/kg
administered intravenously as a 10 min infusion, until the effects of the drug on
QT/QTc interval have been formally characterized, the study will use the exclusion
criteria defined in International Conference on Harmonisation (ICH) Guideline E14 to
exclude subjects with a risk of QT/QTc prolongation, namely:

- A marked baseline prolongation of corrected QT interval >450 ms in two ECGs, or

- A history of risk factors for Torsade de Pointes (e.g., heart failure,
hypokalemia, family history of Long QT Syndrome).
