About this study

Malaria is the most important human parasitic disease and is responsible of high morbidity and mortality in resource-poor countries. Pregnant women, who are a high-risk group, are almost always excluded from clinical trials; thus, the investigators lack sufficient information on the safety and efficacy of most antimalarials in pregnancy. The recommendation of the World Health Organization to use artemisinin combination therapy (ACT) in the 2nd and 3rd trimester is already implemented in several African countries, however documentation of their efficacy and safety in pregnancy is still limited. Thus, the investigators propose to evaluate the efficacy and safety of 4 ACT(artemether-lumefantrine, amodiaquine-artesunate, mefloquine-artesunate and dihydroartemisinin-piperaquine), when used to treat pregnant women with P. falciparum malaria; the results will help to recommend the optimal therapy for this high-risk group in Africa.

Read the detailed description

Malaria is the most important human parasitic disease. Although pregnant women are a high-risk group, they are almost systematically excluded from clinical trials, for fear of teratogenicity and embryotoxicity; thus, we generally lack sufficient information on the safety and efficacy of most antimalarials in pregnancy, as well as evidence-based recommendations for the prevention and treatment of malaria during pregnancy.

The WHO recommendation to use artemisinin combination therapy (ACT) in the 2nd and 3rd trimester is already implemented in several African countries. However, the documentation of their efficacy and safety in pregnancy is still limited, especially concerning the African contexts.

Therefore, we propose to test 4 fixed-dose combinations (artemether-lumefantrine, amodiaquine-artesunate, mefloquine-artesunate and dihydroartemisinin-piperaquine), to evaluate their efficacy and safety when administered to pregnant women (2nd and 3rd trimester) infected with P. falciparum. Explanatory variables will be collected for treatment failure (PCR-corrected) and for recurrent parasitaemia. The primary hypothesis tested will be the clinical equivalence (pair-wise non-inferiority) of the 4 treatment regimens with clinical equivalence defined as difference in treatment failure rates (PCR corrected) of 5% or less.

In addition, an attempt will be done to carry out in vitro testing at the time of recurrent infection. However, the success of the test will depend on the parasite density. In addition, blood samples collected on filter paper at day 0 and at day of recurrent parasitaemia will be genotyped for the search of known molecular markers related to drug resistance. Not all samples will be analyzed; rather these will be selected according to the therapeutic response so that the prevalence of molecular markers will be compared between treatment successes, true treatment failures and new infections.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Dihydroartemisinin-piperaquineDrug

    Also called DHAPQ, Eurartesim

    DHA-PQ tablets are green film coated intended for oral use and contain 20/160mg or 40/320mg of dihydroartemisinin (DHA) and piperaquine phosphate (PQ) respectively. In this trial the 40/320mg for adults will be used. Developed by Sigma Tau in partnership with Medicines for Malaria Venture.

  • Artesunate-mefloquineDrug

    Also called MQAS

    MQAS will be provided as a fixed-dose ACT. There are 2 strengths (AS25+MQ55mg and AS100+MQ220mg) and dosing regimen is calculated according to 12 mg/kg AS and 24mg/kgMQ total dose over three days. Pregnant women will receive 2 tablets/day for 3 days. It is developed by Farmanguinhos with the Drugs for Neglected Diseases Initiative. To be noted: if the FDCs will not get the WHO pre-qualification before the start of recruitment, the separate AS and MQ will be used

  • Artesunate-amodiaquineDrug

    Also called AQAS, artesunate-amodiaquine Winthrop®

    AQAS, developed by teh DNDi with Sanofi-Aventis and manufactured by Sanofi-Aventis, has been pre-qualified by the WHO in 2008 and is available in several African countries, including those involved in this trial. AQ-AS tablets are round, yellow on one side and white-slightly yellow on the other, with a breaking bar, AS engraved on one side and either 25, 50 or 100 on the other side. Tablets to be used in this trial are those 100mg/270mg AS/AQ, containing 100 mg of artesunate, 352.640 mg of amodiaquine hydrochloride corresponding to 270mg of amodiaquine base.

  • Artemether-lumefantrineDrug

    Also called AL, Coartem, Riamet

    AL (tablets containing a FDC of 20 mg of artemether and 120 mg of lumefantrine) is manufactured by Novartis and has been extensively used in Africa for the treatment of uncomplicated malaria. AL was registered in Switzerland in 1999, has since received marketing authorisation in several endemic and non-endemic countries and it is WHO pre-qualified.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Dihydroartemisinin-piperaquine, Artesunate-mefloquine and Artesunate-amodiaquine in people with Malaria in Pregnancy, run by Institute of Tropical Medicine, Belgium at 7 sites in 4 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in Ghana, Burkina Faso, Malawi, Zambia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Treatment Failure (PCR adjusted) (time frame: Day 63). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00852423, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Mar 2016.
