Study summary

Primary Objective:

  • To demonstrate the non-inferiority, in terms of clinical and parasitological efficacy on D28 of administration of Coarsucam™ (artesunate+amodiaquine fixed-dose combination), as a single daily dose, in comparison with administration of Coartem® (artemether+lumefantrine).

Secondary Objectives:

To compare the 3 treatment groups in terms of:

  • clinical and parasitological efficacy on D14 and D28 on the global population and on the subpopulation consisting of children aged under 5 years and that for patients aged 5 years and over
  • clinical and laboratory safety
  • time to parasite clearance
  • time to clearance of fever
  • changes in gametocytaemia
  • impact on anaemia

Inclusion criteria

  • adults or children weighing ≥ 10 kg
  • residing in the zone covered by the investigating centre throughout the entire follow-up period
  • capable of receiving oral treatment
  • axillary temperature ≥ 37.5 degrees Celsius at the inclusion visit or history of fever within the previous 24 hours
  • infection with Plasmodium falciparum, with parasite density in the blood ranging from 1000 to 200,000 asexual forms per cubic millimetre
  • from each participant or parents (guardians) for the children
  • negative urinary pregnancy test for all women of child-bearing age

Exclusion criteria

Exclusion criteria:

  • presence of at least one serious or clinical danger sign of malaria: prostration, consciousness disorders, recent and repeated convulsions , respiratory distress, inability to drink, uncontrollable vomiting, macroscopic haemoglobinuria, jaundice, haemorrhagic shock, systolic Blood Pressure \< 70 mmHg in adults or \< 50 mmHg in children, spontaneous bleeding, inability to sit or stand
  • serious concomitant disease
  • allergy to one of the medicinal products (drug substance or )

  • clinically documented heart disease (bradycardia, extrasystoles, exertional dyspnoea, systolic or diastolic extrasystoles, gallop rhythm...)
  • history of hepatic and (or) haematological impairment during treatment with amodiaquine
  • intake of medication metabolised by cytochrome CYP2D6 (e.g. metoprolol, flecainide, imipramine, amitriptyline, clomipramine) or (e.g. erythromycin, ketoconazole, itraconazole, cimetidine, protease inhibitors)
  • family history of congenital prolongation or sudden death or another clinical condition known to prolong the QTc interval
  • intake of medication known to prolong the QTc interval, such as class IA and III antiarrythmics, neuroleptics, antidepressant agents, certain antibiotics including drugs in the macrolide class, fluoroquinolones, imidazole and triazole, antifungal agents, certain non-sedative antihistamines (terfenadine, astemizole) and cisapride
  • certain known electrolyte imbalances such as hypokalaemia or hypomagnesaemia
  • patient having received artesunate + amodiaquine or artemether + lumefantrine at a suitable dosage within 30 days prior to inclusion

Terms in these criteria, in plain language(6)

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.

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.

Excipients

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

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.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

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.
