NCT03576313

Brief Summary

This is a community-based cluster-randomized trial in which a novel approach to interrupt residual malaria transmission by mass drug administration (MDA) with ivermectin (IVM) combined with dihydroartemisinin-piperaquine (DP) will be tested. This cluster-randomized trial will involve 32 villages in the Upper River Region of The Gambia that will be randomized to MDA with IVM and DP or to standard of care in a ratio 1:1. This trial aims at establishing whether MDA with IVM and DP can reduce or interrupt malaria transmission in medium to low transmission settings by reducing vector survival and the human reservoir of infection. MDA with IVM and DP will be implemented in the intervention villages and all human settlements in the buffer zone, with the aim of minimizing spillover effects. Control clusters will receive standard malaria control interventions as implemented by the National Malaria Control Program. The primary outcomes will be the prevalence of malaria infection determined by molecular methods in all age groups at the peak of the second transmission season (November-December 2019) and the vector's parous rate 7-14 days after MDA.

Outcome Measures

Primary Outcomes (2)

  • prevalence of malaria infection

    Prevalence of malaria infection determined by molecular methods number of participants with a positive varATS quantitative PCR divided by the total number of participants sampled

    at 12 months

  • Vector's parous rate

    Malaria prevalence will be used as an indicator of on-going malaria transmission, while vector's parous rate will quantify the effect of IVM on vector survival and mosquito population age structure. Proportion: number of parous vectors divided by the total number of collected vectors

    7-14 days after mass drug administration (MDA)

Secondary Outcomes (7)

  • malaria prevalence

    at 6 months

  • incidence of clinical (laboratory confirmed) malaria cases

    after MDA over 6 months period

  • serological markers of recent malaria

    after MDA over 6 months period

  • serological markers of recent Anopheles exposure

    after MDA over 6 months period

  • mosquito density

    over 24 months after MDA

  • +2 more secondary outcomes

Other Outcomes (1)

  • drug resistance markers

    after MDA 6 months

Study Arms (2)

intervention: IVM and DP

EXPERIMENTAL

Mass Drug Administration with ivermectin (IVM) and dihydroartemisinin-piperaquine (DP) will be given to participants in the intervention villages plus the NMCP standard malaria control intervention

Drug: dihydroartemisinin-piperaquine (DP)Drug: ivermectin (IVM)Other: standard malaria control interventions only

control: standard malaria control intervetions

ACTIVE COMPARATOR

Participants in the control clusters will receive only standard malaria control interventions such as Artemether Lumefantrine, LLINs, IRS, SMC and IPTp as implemented by the National Malaria Control Program (NMCP) of the Gambia

Other: standard malaria control interventions only

Interventions

DP will be available as tablets of 320/40mg and 160/20mg piperaquine/ dihydroartemisinin per tablet. Administration of a full course of DP will be done as per manufacturer's guidelines once daily for 3 days and according to body weight. DP will be taken orally with water and without food

intervention: IVM and DP

IVM will be available as tablets of 3mg or 6mg strength. It will be given at 300-400μg/kg/day over 3 days (to the nearest whole tablet). IVM will also be taken on an empty stomach with water

intervention: IVM and DP

this is the standard malaria control interventions in the Gambia

control: standard malaria control intervetionsintervention: IVM and DP
