Study summary

A randomised, double-blind single-dose study to determine the efficacy, safety, tolerability and pharmacokinetics of OZ439 (artefenomel) in combination with piperaquine (PQP) in patients > 0.5 years and \<= 70 years of age with uncomplicated Plasmodium falciparum malaria in Africa and Asia (Vietnam).

Interim analyses for futility were planned. Adults and children will be included through progressive step-down in age following safety review by an independent safety monitoring board (ISMB).

If the study were to meets its efficacy objectives, this will inform dose setting for Phase III studies.

Read the detailed description

A randomised, double-blind single-dose (loose combination) study in the target patient population of children > 0.5 years and \<= 5 years of age in Africa and patients of all ages in Asia (> 0.5 years and \<= 70 years) with uncomplicated Plasmodium falciparum malaria. Patients > 5 years in Africa were also to be recruited in a safety age step down procedure. The underlying assumption was that children of 5 years or less in Africa and all ages in Asia will have a higher probability of having lower immunity and hence potentially require higher drug exposure to achieve efficacy and hence the study aimed to recruit 60-80% African children \< = 5 years and 18-36% Asian patients (defined as the target population) and approximately 10% African patients >5 years,

Three OZ439/PQP treatment arms were to be included for patients >= 35 kg (800mg OZ439 in loose combination with PQP doses of either 640, 960, 1440 mg). Doses were scaled for patients \< 35kg based on the weight to achieve similar exposures in patients >= 35kg.

The study was to test for futility and dose arms were to be dropped if the probability was >30% that PCR-adjusted ACPR at Day 28 (ACPR28) was less than 90% (the target efficacy for the study was >= 95% ACPR28). Only data from patients in Asia patients and Africa patients \< 5 years were to be included in the Interim analysis, although all patients were to be included in the final analysis. Interim analyses were to occur after recruitment of approximately 50 evaluable patients per dose cohort and thereafter approximately after every 25 patients.

In a separate process, the safety of OZ439/PQP treatment arms was to be assessed at scheduled time points by an ISMB and adults and children were included through progressive step-down in age range following safety evaluation

Following Screening and informed consent, patients were to receive study drug and were to be followed for clinical signs of malaria (parasitaemia and temperature), safety assessments and pharmacokinetics up to Day 42 following dosing (Day 63 at selected sites).

Terms in these criteria, in plain language(14)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

QT and QTc

On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.

The study may name a correction formula and a limit in milliseconds, often around 450–480.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Not marked actual or estimatedDates not marked actual or estimated

The record gives a start of Jul 2014, a primary completion of Oct 2015 and a completion of Nov 2015. It does not say whether these dates are actual or estimated.

Results were first posted in Jan 2017, 1 year 3 months after primary completion.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 10, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
