Study summary

Primary Objective:

To determine whether a single dose combination of OZ439 (Artefenomel)/FQ (Ferroquine) was an efficacious treatment for uncomplicated Plasmodium falciparum malaria in adults and children.

Secondary Objectives:

  • To evaluate the efficacy of OZ439/FQ:

    • To determine the incidence of recrudescence and re-infection.
    • To determine the time to relief of fever and parasite clearance.
  • To evaluate the safety and tolerability of OZ439/FQ in adults and children.
  • To characterize the pharmacokinetics of OZ439 in plasma, FQ and its active metabolite SSR97213 in blood.
  • To determine the blood/plasma ratio for FQ and SSR97213 in some participants at limited time points in 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.

CYP3A (CYP3A4) inhibitors and inducers

CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.

Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.

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.

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.

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.

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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

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.

Excipients

The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.

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.

Results

Posted Oct 19, 2020
Limitations and caveats
The study was terminated early because all treatment arms met the futility criteria for efficacy during the pre-planned interim analysis. On 02-August-2018, recruitment in Asia was stopped due to lack of efficacy.

Participant flow

Study conducted at 12 active sites in 7 countries. Total of 806 participants were screened between 25 July 2015 and 22 July 2019, of which 377 were randomized to 1 of 4 treatment arms (via Integrated Web Recognition System using permuted block randomization schedules). 429 participants failed screening mainly due to meeting exclusion criteria.

SecondaryFever Clearance Time (FCT): African <=5 Years PP Population

FCT was defined as the time (in hours) from start of study drug administration to the first assessment of adjusted body temperature \<37.5°C, confirmed by second assessment, taken within \>=6 to \<=12 hours of the first assessment. Only participants with fever (adjusted body temperature \>=37.5°C present at Baseline) and did not receive paracetamol on day of study drug administration until 96 hours after study drug administration were included in FCT analysis. Participants with no event were censored at the time of study completion, premature study discontinuation, including switch to established anti-malarial treatment or start of any other treatment with anti-malarial activity, whichever was earliest. Kaplan-Meier method was used for the estimation.

An AE was defined as any untoward medical occurrence in a participant who received study drug and did not necessarily had to have a causal relationship with the treatment. SAEs were any untoward medical occurrence that resulted in any of the following outcomes: death, life-threatening, required initial or prolonged in-patient hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect, or considered as medically important event. TEAEs were defined as AEs that developed or worsened or became serious during on-treatment phase that was defined as the time from the start of the first dose of double-blind drug administration up to the Day 63. AE of special interest (AESI) was an AE (serious or non-serious) of scientific and medical concern specific to the Sponsor's product or program, for which ongoing monitoring and immediate notification by the Investigator to the Sponsor was required.
