Plasmodium Falciparum Malaria (Uncomplicated) Clinical Trial
Official title:
A Multi-centre Randomised Controlled Non-inferiority Trial to Compare the Efficacy, Safety and Tolerability of Triple Artemisinin-based Combination Therapies Versus First-line ACTs + Placebo for the Treatment of Uncomplicated Plasmodium Falciparum Malaria in Asia
A partially blinded randomised controlled non-inferiority trial comparing the efficacy, tolerability and safety of Triple ACTs artemether-lumefantrine + amodiaquine (AL+AQ) and artesunate- mefloquine+piperaquine (AS-MQ+PPQ) with the ACTs artemether-lumefantrine + placebo (AL+PBO) and artesunate- mefloquine + placebo (AS-MQ+PBO) (with single-low dose primaquine in some sites) for the treatment of uncomplicated Plasmodium falciparum malaria to assess and compare their efficacy, safety, tolerability.
Subjects will be randomized to up to four arms: artemether-lumefantrine + amodiaquine, artemether-lumefantrine + placebo, artesunate-mefloquine + piperaquine and artesunate-mefloquine + placebo. As a contingency measure in case of significant differences in the efficacy or safety of one of the combinations being tested and/or study drug expiry or unavailability, subjects may be randomised to 2 arms with a matching ACT-TACT pair, i.e., with artemether-lumefantrine + placebo or artemether-lumefantrine + amodiaquine OR artesunate-mefloquine + placebo or artesunate-mefloquine + piperaquine. Some sites may randomize between 2 arms only with matching ACT-TACT pairs, i.e., artemether-lumefantrine + placebo or artemether-lumefantrine + amodiaquine OR artesunate-mefloquine + placebo or artesunate-mefloquine + piperaquine. In the control arms, the ACT will be co-packed with a matched (appearance) placebo. In lower transmission settings (Annual Parasite Incidence <50 per 1000 population per year) the treatment will include a single 0.25 mg/kg gametocytocidal dose of primaquine as recommended by the WHO for children ≥10 kg. All drug administrations will be observed. Subjects will be treated in an in-patient unit for 3 days and followed up weekly up to D63. Microscopy to detect and quantify malaria parasitaemia will be performed daily (more frequently in patients with parasite density of >5000/µL at inclusion) during hospitalization, at all weekly and unscheduled visits. A physical examination and measurements of vital signs along with a symptom questionnaire for tolerability will be performed and recorded through a standardized method at baseline, daily during admission and weekly during follow up through D42 and at all unscheduled visits. Physical exam, vital sign measurements and assessments of symptoms will be performed on D49, D56, and D63 only for patients who are parasitaemic or those who report fever or other symptoms. Electrocardiographs will be performed during admission (H0, H4, H52, or H64) and day 42 of follow up to assess and compare the effect of ACTs and TACTs antimalarials on QT or QTc-intervals. The DeTACT-ASIA Trial is funded by UK Aid from the UK government's Foreign, Commonwealth and Development Office (FCDO). The FCDO project number is 300341-114. ;
