Triple Artemisinin-based Combination Therapy for Delaying Drug Resistance Development - a Randomized Clinical Trial
Can Triple Artemisinin-based Combination Therapy for Treatment of Uncomplicated Plasmodium Falciparum Malaria, Delay Drug Resistance Development of Plasmodium Falciparum in Tanzania: a Randomized Three Arm Clinical Trial
Triple Artemisinin-based Combination Therapy for Delaying Drug Resistance Development - a Randomized Clinical Trial (NCT05764746) is a Phase 2 / Phase 3 interventional studying Uncomplicated Plasmodium Falciparum Malaria, sponsored by Muhimbili University of Health and Allied Sciences. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.
About This Trial
Background: Artemisinin resistance has emerged in parts of Southeast Asia, and there are reports in Africa of reduced susceptibility of Plasmodium falciparum parasites against artemisinin-based combination therapy (ACT). No new drugs are available in the pipeline to replace ACTs in case they fail. This study aims to assess whether a sequential administration of triple ACTs with different partner-drugs can improve the efficacy of ACT for treatment of uncomplicated malaria. Methods: A health facility-based, three-arm partially blinded randomized clinical trial will be conducted to assess efficacy and safety of a sequential administration of artemether-lumefantrine followed immediately by artesunate-amodiaquine (AL+ASAQ) or artemether-lumefantrine with by amodiaquine (AL+AQ) compared to artemether-lumefantrine plus placebo (AL+PBO). Eligible children aged 6 - 120 months and with microscopy confirmed uncomplicated P. falciparum malaria will be enrolled, administered with trial medicines and followed-up at 0 (just prior to first drug intake) and 8 hours on day 0, 12 hourly on days 1, 2, 3, 4, 5, followed by once daily on days 6, 7, 8, 9, 10, 11, 12, 13, 14, 21, 28, 35, 42 and 56 for clinical and laboratory evaluations. Clinical evaluation will involve assessment of signs and symptoms related to the disease and or trial medicine during follow-up. Laboratory evaluation will include microscopic determination of presence of malaria parasites and species, hemoglobin level, molecular analysis for markers of drug resistance and to differentiate recrudescence from new infection. The primary outcome will be Polymerase Chain Reaction (PCR)-adjusted adequate clinical and parasitological cure rate on days 28 and 42. Expected outcomes: The findings will give an insight on whether 3 ACTs are more efficacious than the use of first-line regimen alone, and are tolerable for treatment of uncomplicated falciparum malaria.
What Stage of Research Is This?
Phase 2 trials evaluate whether a treatment actually works against Uncomplicated Plasmodium Falciparum Malaria and continue monitoring side effects. Phase 2 enrolls larger groups (typically 100–300 patients) and produces the first real efficacy signal. A successful Phase 2 readout is what unlocks the much larger Phase 3 confirmatory trials needed for FDA approval.
This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.
A target enrollment of 384 participants makes this a sizable late-stage trial. Studies in this range typically have enough power to detect clinically meaningful differences from a comparator and to characterize less-common side effects.

Bring the printable summary of this trial — including the NCT ID (NCT05764746), the sponsor (Muhimbili University of Health and Allied Sciences), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.
Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up?

Who can participate in NCT05764746?
Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.
How do I contact the trial site for NCT05764746?
Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.
Is participating in a clinical trial safe?
Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
