Brief Summary

A randomised, placebo-controlled, dose-escalation study to investigate safety and toleration of OZ439 OD for 3 days to healthy male and female volunteers. The study aims:

• To determine the safety and tolerability of ascending doses of OZ439 OD for three days.
• To assess pharmacokinetic parameters of ascending doses of OZ439 given OD.
• To identify the maximum tolerated dose of OZ439 administered.

Outcome Measures

Primary Outcomes (2)

• OZ439 AUCτ

  OZ439 Area under the plasma concentration vs time curve from time zero to the time of the last quantifiable concentration t calculated using a log-linear trapezoidal method

  pre-dose, 2, 4, 6, 8, 12, and 18 hours post-dose Day 1and Day 3, pre dose Day 2 and 4 hours post dose Day 2, and 24, 48, 72, 96 and 168 hours post 3rd dose and at follow up.

Secondary Outcomes (2)

  pre-dose, 2, 4, 6, 8, 12, and 18 hours post-dose Day 1and Day 3, pre dose Day 2 and 4 hours post dose Day 2, and 24, 48, 72, 96 and 168 hours post 3rd dose and at follow up.

• OZ439 t½

  pre-dose, 2, 4, 6, 8, 12, and 18 hours post-dose Day 1and Day 3, pre dose Day 2 and 4 hours post dose Day 2, and 24, 48, 72, 96 and 168 hours post 3rd dose and at follow up.

Clinically significant disease or any condition or disease that might affect drug absorption, distribution or excretion 3. History of allergic reactions to artemisinin-based compounds or any other clinically relevant allergy to drugs or food 4. Clinically relevant history of both soya and cow's milk intolerance/allergy 5. Clinically significant abnormal laboratory, vital signs or other safety findings as determined by medical history, physical examination or other evaluations conducted at screening or on admission 6. Electrocardiogram (ECG) abnormalities in the standard 12-lead ECG (at screening) and/or 24-hour 5 lead Holter ECG (at screening) 7. Any abnormalities in rhythm, conduction or morphology of resting ECG that may interfere with the interpretation of QTc interval changes 8. Prolonged QTcF \>450 ms or shortened QTcF \<340 ms, or family history of Long QT Syndrome 9. History or current evidence of any clinically relevant cardiovascular, pulmonary, hepatic, renal, gastrointestinal, haematological, endocrinological, metabolic, neurological, psychiatric, or other disease 10. Positive results in any of the serology tests for Hepatitis B Surface Antigen (HbsAg), anti Hepatitis core antibody (anti HBc Ig G \[and anti HBc IgM if IgG is positive\], Hepatitis C antibodies (anti HCV), and HIV 1 and 2 antibodies (anti HIV 1/2) 11. Confirmed positive results from urine drug screen (amphetamines, benzodiazepines, cocaine, cannabinoids, opiates, barbiturates, and methadone) or from the alcohol breath test at screening and on admission 12. History or clinical evidence of alcohol or drug abuse. Alcohol abuse is defined as regular weekly intake of more than 21 units for males and 14 units for females; drug abuse is defined as compulsive, repetitive and/or chronic use of drugs or other substances with or without problems related to their use and/or where stopping or a reduction in dose will lead to withdrawal symptoms 13. Is pregnant or lactating (female subjects who are of childbearing potential must have negative pregnancy tests at screening and admission) 14. Mentally handicapped 15. Participation in a drug trial within 90 days prior to first drug administration 16. Use of any medication (incl. over-the-counter (OTC) medication) within 2 weeks prior to drug administration (Day 1) or within less than 10 times the elimination half-life of the respective drug, or anticipated concomitant medication during the treatment periods, (whichever is longer), including herbal, traditional and alternative medications. Excluding oral contraceptives (combination oestrogen/progesterone pills), injectable progesterone or subdermal implants. Limited amounts (4g/day for 2 days) of paracetamol will be permitted for the treatment of AEs 17.
