Study summary

A cluster-randomized control trial will study the effect of insecticide-treated wall lining on malaria transmission in Bomi County, Liberia. Half of the villages enrolled in the study will receive insecticide-treated wall lining covering their walls and ceilings in addition to long-lasting insecticidal nets, while the other half will be protected by existing long-lasting insecticidal nets.

Read the detailed description

Long-lasting insecticidal nets (LLINs) are the established vector control product for malaria control. In Bomi County Liberia, LLINs have been distributed but malaria prevalence in children under 5 remains high, with prevalence in study villages found to be 42% in April 2014. The major malaria vector species are resistant to pyrethroid insecticides approved for use in LLINs, and new control measures with non-pyrethroid active ingredients may protect the population.

Study arms

  • No intervention
    Control

    21 clusters composed of one or more villages with a total number of 30 to 70 children under 5 years old. Routine distribution of long-lasting insecticidal nets is the only malaria control intervention.

  • Experimental
    Intervention

    21 clusters composed of one or more villages with a total of 30 to 70 children under 5 years old. Routine distribution of long-lasting insecticidal nets is available and in addition insecticide treated wall lining is installed in all sleeping areas with homeowner consent. All 4 walls and the ceiling are covered with lining.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2014 to primary completion in Jun 2016, 27 months.

Of 24 interventional studies with no phase under Malaria, Falciparum, half reached primary completion within 20 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 31. This study's 27 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 1, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
