About this trial

This is an interventional basic science trial for Malaria focused on measuring malaria, dose escalation, safety, tolerability, maximum tolerated dose

Eligibility Criteria

18 Years - 55 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusions:

  1. healthy males or females of any race aged 18 - 55 years
  2. BMI of 18 - 30 kg/m2 inclusive at screening
  3. Agree to use acceptable methods of contraception if of childbearing potential
  4. Capable of understanding and complying with the requirements of the protocol and must have signed the informed consent form
  5. Females are either of child bearing potential or are confirmed as post-menopausal. Post-menopausal is defined as being amenorrheic for 12 months without an alternative medical cause with a screening FSH level ≥ 25.8 IU/L

Exclusions:

  1. Male subjects with female partner(s) who is (are) pregnant or lactating from the time of the first administration of study medication
  2. 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

  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. Treatment with herbal supplements during the 7 days prior to drug administration, or use of vitamins during 48 hours prior to drug administration
  18. Is not permitted to use strong inhibitors and/or inducers of CYP450 within 21 days prior to the planned first drug administration
  19. Subjects have veins unsuitable for intravenous puncture or cannulation on either arm (e.g. veins that are difficult to locate, access or puncture veins with a tendency to rupture during or after puncture)
  20. Blood ALT, AST and bilirubin should be in the normal range at screening and on admission
  21. Donation of more than 500 mL of blood within 90 days prior to drug administration
  22. Subjects must be non-smokers for at least three months prior to first drug administration
  23. Any circumstances or conditions, which, in the opinion of the PI, may affect full participation in the trial or compliance with the protocol
  24. Legal incapacity or limited legal capacity at screening
  25. Subjects who are vegetarians, vegans or have any dietary restrictions conflicting with the study standardised menus

5. Study Description

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.
Detailed Description
This study will be conducted in a randomised, placebo-controlled dose-escalation design with OZ439 OD administered with full fat milk for three days to healthy male and female subjects between 18 to 55 years of age, using features of an adaptive study design. The study is expected to have three cohorts with a total of 36 healthy male and female subjects. An additional two cohorts may be used if required. The results of this study will inform the maximum tolerated exposure of OZ439 following OD dosing for three days in subjects who are not fasted.
