Trial summary

Background: In high-transmission settings, up to 70% of school-aged children harbour malaria parasites which is mostly asymptomatic, thus, from an epidemiological point of view, they contribute significantly as reservoir to onward malaria transmission to others. Read more about this study

About this study

Official title: Effectiveness and Safety of Intermittent Preventive Treatment for Malaria Using Either Dihydroartemisinin-piperaquine or Artesunate-amodiaquine in Reducing Malaria Related Morbidities and Improving Cognitive Ability in School-aged Children in Tanzania: A Controlled Randomised Trial

Background:

In high-transmission settings, up to 70% of school-aged children harbour malaria parasites which is mostly asymptomatic, thus, from an epidemiological point of view, they contribute significantly as reservoir to onward malaria transmission to others. In endemic areas, malaria accounts for around 50% of the mortality, 13-50% of all school absenteeism, and causes anaemia in approximately 85 million school-aged children of sub Saharan Africa that also impairs the cognitive development of children. Intermittent preventive treatment (IPT) of pregnant women as well as seasonal malaria chemoprevention in children under the age of five have been implemented in several sub-Saharan countries and have proven to be very effective. However, none of these IPT strategies is targeting school children. A clinical trial is being conducted to expand the IPT by testing effectiveness and safety of two antimalarial drugs Dihydroartemisinin-piperaquine (DP) and Artesunate-amodiaquine (ASAQ) in preventing malaria related morbidity in school aged children (IPTsc) living in high endemic areas.

Methods:

A randomized, open label, controlled trial will enrol 1602 school children aged 5-15 years, who will receive either DP or ASAQ or control (no drug ), using a "balanced block design" with the "standard of care" arm as reference. The interventional treatments are given every 4 months 3 rounds for the first year. A second non-interventional year will assess possible rebound effects. All study-arms receive bed nets, early diagnosis and care for malaria, and praziquantel and albendazole as mass treatment for helminthiasis. The primary endpoint are change from baseline in mean haemoglobin concentration at months 12 and 20 of follow-up and clinical malaria incidence from month 0 till months 12 and 20 of follow up. Adverse events will be monitored throughout the study. Mixed design methods will be used to assess the acceptability, cost-effectiveness and feasibility of this IPTsc as part of a more comprehensive school children health package.

Discussion:

The national school health programme (NSHP), Tanzania, combines schistosomiasis and soil transmitted helminthes (STH) control package under national schistosomiasis and STH control programme (NSSCP). Malaria intervention using IPTsc strategy may be integrated in NSHP with the same platform as NSSCP, however, there is limited systematic evidence to assess the operational feasibility of this approach. School aged children are a reachable target population in any endemic malaria setting. The suggested strategy will provide effective protection against malaria, hasten either the elimination process and/or diminish the reservoir and burden.

What is being measured

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

  1. Change from baseline in mean haemoglobin concentration at months 12 and 20 of follow-up

    Will measure change from baseline haemoglobin concentration at month 12 (intervention period) and at month 20 (post intervention period to assess rebound effect) [Note: a trend of change at each visit will also be assessed with respect to malaria seasonality]

    Measured: at months 0, 12 and 20

  2. Clinical malaria incidence from month 0 till months 12 and 20 of follow up

    number of symptomatic malaria episodes during and after intervention period

    Measured: at months 0, 12 and 20

Secondary outcomes (9)
  1. Prevalence of asymptomatic malaria infections at month 0, 12 and 20 of follow up

    to be measured from microscopic detection of malaria parasite on blood slides

    Measured: from month 0 till month12 and 20

    Polymerase chain reaction (PCR) confirmed from random subset of finger prick dry blood spots samples

    Measured: at months 0, 12 and 20

  3. Prevalence of soil transmitted helminths and schistosomiasis

    A stool sample will be used to determine prevalence (defined as adult or eggs) of STH and S. mansoni infection determined by duplicate Kato-Katz thick smears technique. Urine samples will be visually examined for the presence of blood (macrohaematuria) followed by laboratory examination for schistosomiasis infection (S.haematobium)

    Measured: at baseline, at month 12 and month 20.

  4. Prevalence of schistosomiasis

    Urine samples will be visually examined for the presence of blood (macrohaematuria) followed by laboratory examination for schistosomiasis infection (S.haematobium) for confirmation.

    Measured: at baseline, at month 12 and month 20.

    from random subset of finger prick dry blood spots samples

    Measured: at baseline, at month 12 and 20.

  6. Proportion of children seropositive for Plasmodium falciparum AMA-1 and MSP-119 at baseline, at month 12 and 20

    from random subset of finger prick dry blood spots samples, Antibody responses to P. falciparum blood-stages antigens, apical membrane antigen (AMA-1) and merozoite surface protein (MSP-119) will be determined.

    Measured: at baseline, at month 12 and 20.

  7. Change in serum antibody responses to Plasmodium falciparum AMA-1 and MSP-119 at baseline, at month 12 and 20

    From random subset of finger prick dry blood spots samples to be eluted for ELISA

    Measured: at baseline, at month 12 and 20.

  8. Percentages of school children with malnutrition through WHO's BMI z-score

    weight in kilograms and height in meters will be combined to report BMI in kg/m^2

    Measured: at month 0, 12, and 20

  9. Relative risk (RR), for all adverse events categorised to severity at month 12 and 20

    Adverse events will be detected throughout the study, Each intervention arm will be compared to control arm to determine risk of an adverse event among the two arms. Also events in two intervention arms will be compared to each other to assess risk in the two intervention arms.

    Measured: at month 12 and 20

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 5 inclusion and 10 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 Nov 2024. 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 Tanzania. 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?

Change from baseline in mean haemoglobin concentration at months 12 and 20 of follow-up (time frame: at months 0, 12 and 20). 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 NCT03640403, 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 20 Nov 2024.
