About this study

Official title: The Pharmacokinetic of the Fixed-dose Combination of Mefloquine-Artesunate in Plasmodium Falciparum Malaria Infection in Pregnant Women

Malaria in pregnancy is a major public health problem in Sub-Saharan Africa. Over the past decades, P. falciparum has shown increasing resistance to chloroquine and Sulphadoxine-Pyrimethamine, which has prompted a change in treatment approach; artemisinin containing combination therapies (ACTs) are now the standard treatment of P. falciparum malaria in areas with established resistance to traditional therapies. However, a standard approach for using ACT in pregnancy does not exist in Africa, where some countries keep on using quinine, while others allow the use of ACTs. Thus, there is need of establishing the safety and efficacy of ACTs in malaria-infected pregnant women. Since the pharmacokinetic of antimalarials may be altered during pregnancy and since available pharmacokinetic data are still somewhat limited, we propose to carry out a study confirming or disproving existing pharmacokinetic data (collected in South-East Asia), before starting any larger African efficacy and safety trials. The fixed-dose combination mefloquine-artesunate (MQ-AS), developed by the Drugs for Neglected Diseases Initiative, will be used in the study, which will compare the pharmacokinetics of MQ-AS for treatment of P.falciparum in 24 pregnant women in the second and third trimesters, to the pharmacokinetics of this regimen in 24 matched non-pregnant P.falciparum infected women. The study will be carried out in Burkina Faso.

Read the detailed description

Malaria during pregnancy constitutes a major public health problem in Sub-Saharan Africa, where it increases the risk of low birth weight (<2500g), infant mortality, infant morbidity during the first year of life, prematurity and infant anemia. Over the past decades, P. falciparum has shown increasing resistance to standard antimalarial therapy (chloroquine CQ and Sulphadoxine-Pyrimethamine). The inexorable development and spread of P. falciparum resistance to antimalarials has prompted a change in treatment approach; artemisinin containing combination therapies (ACTs) are now the standard treatment of P. falciparum malaria in areas with established resistance to the traditional therapies. The use of combinations reduces the theoretical likelihood of selecting resistant mutants; it is hoped that this strategy will delay the development of new resistances.

A standard approach for using ACT in pregnancy does not exist in Africa. Even if the World Health Organization endorses the use of ACTs for treatment of uncomplicated malaria in 2nd and 3rd trimesters of pregnancy, some countries keep on using quinine, while others allow the use of ACTs. These different approaches point out to the necessity of establishing the safety and efficacy of ACTs in malaria-infected pregnant women. Nevertheless, considering that the pharmacokinetic of antimalarials may be altered during pregnancy (potentially leading to under-dosing) and that the available safety and pharmacokinetic data are still somewhat limited, it is important to carry out a preliminary pharmacokinetic study confirming or disproving available data (collected in South-East Asia), before starting any larger African efficacy and safety trials.

The ACT regimen mefloquine-artesunate (MQ-AS) has recently been developed as a fixed-dose combination by the Drugs for Neglected Diseases Initiative (DNDi) and has been registered in Brazil (the country of manufacture) in 2008. Artesunate is an artemisinin derivative with a rapidly increasing positive experience in pregnancy, while Mefloquine (Lariam®) has been used for many years for both prevention and treatment of malaria, and has been shown to be safe in pregnant women. The convenient dosing afforded by a fixed drug combination makes MQ-AS a very promising candidate for use in treating pregnant women in Africa, as rescue treatment alternative to quinine. Since preliminary data suggest that the peak concentration of mefloquine is lowered in pregnant women, further studies on safety, efficacy, and dose optimization are imperative, prior to wide-spread adoption of this medicine.

Therefore, we propose to compare the pharmacokinetics of the fixed combination of MQ-AS for treatment of P.falciparum in 24 pregnant women in the second and third trimesters to the pharmacokinetics of this regimen in 24 matched non-pregnant P.falciparum infected women, in an African setting. This will allow for dose optimization in pregnant women.

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 14 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 Sep 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Burkina Faso. 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

To estimate the pharmacokinetic of MQ-AS for treatment of P. falciparum or mixed infection in pregnant compared to non-pregnant women. (time frame: 6 months). 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 NCT00701961, which also lists 2 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 Sep 2010.
