About this study

Official title: The Efficacy and Cost-effectiveness of Malaria Prevention in Pregnancy in an Area of Low and Unstable Transmission in Kabale, Uganda: Use of Intermittent Preventive Treatment and Insecticide-treated Nets.

The purpose of this study is to compare the efficacy and cost-effectiveness of three alternative strategies for the prevention of malaria during pregnancy in an epidemic-prone area of low transmission in the East African Highlands.

The strategies being compared are:

Read more
  • intermittent preventive treatment with sulfadoxine-pyrimethamine (IPT-SP)
  • an insecticide treated net (ITN), and
  • intermittent preventive treatment with SP plus an ITN

In addition to the main individually-randomised trial, outcome data was subsequently also gathered on pregnant women whose houses where sprayed with indoor residual insecticides (IRS) as part of a non-randomised district-wide control programme to compare the impact of IRS with the three intervention arms.

Read the detailed description

Susceptibility to malaria infection during pregnancy and the severity of clinical manifestation are determined by the level of pre-pregnancy immunity, which depends on intensity and stability of malaria transmission. Most intervention trials to prevent malaria during pregnancy have been conducted in areas of intense transmission. The results of trials conducted in high-transmission areas may not be applicable to low transmission areas, where malaria is less frequent but the risk of spontaneous abortion and stillbirth is very high in women of all parities due to lack of sufficient malaria immunity. Routine chemoprophylaxis is generally not recommended in areas of unstable malaria transmission. However, intermittent treatment with an effective anti-malarial drug may be beneficial, especially during periods of malaria transmission. Little work has been carried out amongst pregnant women living in areas of low and unstable transmission in Africa. No data are available on the cost-effectiveness of malaria control in low transmission settings.

This study will compare the efficacy and cost effectiveness of three preventive strategies for the control of malaria during pregnancy in low-transmission settings. The study is located in Kabale district, a highland area in SW Uganda.

Women attending antenatal care are randomised to receive either:

  • intermittent preventive treatment with sulfadoxine-pyrimethamine (IPT-SP)
  • an insecticide treated net (ITN), or
  • intermittent preventive treatment with SP and an ITN. It is hypothesized that when combined with IPT-SP, the additional impact of ITNs by reducing exposure may be greatest where the intensity of transmission is low.

In addition to the main individually-randomised trial, outcome data was subsequently also gathered on pregnant women whose houses where sprayed with indoor residual insecticides (IRS) as part of a non-randomised district-wide control programme to compare the impact of IRS with the three intervention arms.

The study aims to identify the most effective intervention strategies suited to areas characterised by low and unstable transmission. Research findings should be applicable to other hypoendemic areas of the East African highlands.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Intermittent preventive treatment:sulphadoxine-pyrimethamine and Insecticide-treated mosquito bed net in people with Malaria, Falciparum, run by London School of Hygiene and Tropical Medicine at 1 site in Uganda.

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 3 inclusion and 8 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 12 Jan 2017. 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 Uganda. 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?

mean birthweight (time frame: April 2004-Jan 2007). 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 NCT00142207, which also lists 3 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 12 Jan 2017.
