About this study

Official title: LLIN Evaluation in Uganda Project (LLINEUP3): Impact of Long-lasting Insecticidal Nets (LLINs) Treated With Chlorfenapyr Plus Pyrethroid vs LLINs Treated With Piperonyl Butoxide Plus Pyrethroid on Malaria Incidence in Uganda: a Cluster-randomised Trial

In Uganda, the National Malaria Control Division (NMCD) and implementing partners are planning to deliver long-lasting insecticidal nets (LLINs) nationwide, through a mass distribution campaign in 2023. LLINs will be distributed free-of-charge to all Ugandan households, aiming to achieve universal coverage. LLINs treated with a pyrethroid insecticide plus chlorfenapyr (PermaNet Dual, Vestergaard) and LLINs treated with a pyrethroid insecticide plus PBO (PermaNet 3.0, Vestergaard) will be distributed as part of this distribution campaign, presenting an opportunity to rigorously evaluate and compare these two LLINs at scale across Uganda. In collaboration with the MOH, this cluster-randomised trial will compare the impact of LLINs combining chlorfenapyr with a pyrethroid to LLINs combining PBO with a pyrethroid into Uganda's 2023 LLIN distribution campaign, as was done successfully at the time of the last LLIN distribution campaign conducted in 2020-21. A major strength of this trial is the use of malaria incidence as the primary outcome measure. Incidence of malaria, defined as the number of symptomatic cases of malaria occurring in a population at risk over time, is the gold standard for assessing malaria burden. However, cluster-randomised trials using malaria incidence as the primary outcome typically involve study cohorts and are very expensive and logistically challenging. The novel approach for measuring malaria incidence is to utilize data collected routinely at health facilities. By defining target areas around health facilities and collecting data on the location of residence of patients diagnosed with malaria, this study will be able to generate longitudinal measures of malaria incidence at an unprecedented scale across Uganda as done in the LLINEUP2 trial (NCT04566510). These results will inform policies and programmes for malaria and potentially provide evidence to support widescale deployment of dual AI chlorfenapyr-pyrethroid LLINs. This study, the first evaluating PermaNet Dual LLINs, will also provide evidence for a second in class chlorfenapyr net, a potential tool to be added to the malaria control tool kit.

Read the detailed description

This is a cluster-randomised trial to evaluate the impact of long-lasting insecticidal nets (LLINs) distributed in Uganda through the 2023 national universal coverage campaign. A cluster has been defined as the target area surrounding an MRC. A total of 24 clusters will be included in the study, covering 20 moderate-high malaria burden districts in Uganda. Clusters have been randomised in a 1:1 ratio to receive one of two types of LLINs: (1) chlorfenapyr-pyrethroid LLINs (PermaNet Dual, n=12) or (2) PBO-pyrethroid LLINs (PermaNet 3.0, n=12). The intervention, including delivery of the LLINs and social and behaviour change communication (SBCC), will be led by the Ugandan NMCD and other stakeholders. Currently, LLINs are scheduled to be distributed in the study areas during waves 5 and 6 from September to October 2023 as part of the national LLIN distribution campaign. The evaluation of the intervention will include: 1) health facility surveillance at the participating MRCs to generate continuous estimates of malaria incidence for each MRC target area; 2) cross-sectional community surveys at 12- and 24-months post-LLIN distribution to gather information on parasite prevalence, anaemia prevalence, net ownership, coverage, and use, 3) entomology surveys at 12 and 24 months to gather information on vector density. The primary outcome of the trial will be malaria incidence as estimated using the health facility surveillance.

  • Social Behavior Change CommunicationBehavioural

    The NMCD and other stakeholders will take the lead on Social Behaviour Change Communication (SBCC). SBCC activities will use digital and other platforms, including the following: (1) LLIN launch at the World Malaria Day celebrations; (2) regional in-person advocacy meetings; (3) mass media platforms (for advertisements, mini skits, DJ mentions, radio spots, interactive talks); (4) social media platforms; (5) VHTs; (6) operation hotlines and toll-free call centres; (7) community mobilisation (megaphones); and (8) use of appropriate information, education, and communication materials. Communication will include messages about malaria, and use, care, repair and repurposing of bed nets.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of cases of laboratory-confirmed malaria diagnosed at the MRC among patients residing in the target area

    malaria incidence: number of cases divided by the total population of the target area

    Measured: 24-months follow up

Secondary outcomes (6)
  1. Prevalence of parasitaemia

    Proportion of blood smears positive for parasites by microscopy in individuals of all ages at the time of cross-sectional surveys

    Measured: 24-months following LLIN distribution

  2. Prevalence of anemia

    Proportion of children aged 2-4 years with haemoglobin < 11 g/dL at the time of cross-sectional surveys

    Measured: 24-months following LLIN distribution

  3. Proportion of households that owned at least one LLIN

    Proportion of households with at least one LLIN at the time of cross-sectional surveys

    Measured: 24-months following LLIN distribution

  4. Proportion of households that owned at least one LLIN for every two occupants

    Proportion of households with at least one LLIN per every two occupants at the time of cross-sectional surveys

    Measured: 24-months following LLIN distribution

  5. Proportion of household residents who slept under an LLIN the previous night

    Proportion of households residents who report sleeping under LLIN the previous night at the time of cross-sectional surveys

    Measured: 24-months following LLIN distribution

  6. Number of female anopheles mosquitoes collected per household at the time of cross-sectional surveys

    Vector density

    Measured: 24-months following LLIN distribution

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 6 inclusion and 5 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 20 Jan 2026. 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.

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?

Number of cases of laboratory-confirmed malaria diagnosed at the MRC among patients residing in the target area (time frame: 24-months follow up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 20 Jan 2026.
