About this study

Official title: Clinical Trial to Evaluate Intermittent Screening and Treatment and Intermittent Preventive Treatment of Malaria in Asymptomatic Schoolchildren to Decrease P. Falciparum Infection and Transmission

This is an individually randomized, controlled, single blind three arm clinical trial of malaria chemoprevention strategies Arm 1: Intermittent screening and treatment (IST) - students will receive treatment if they have a positive high sensitivity rapid diagnostic test (RDT). Arm 2: Intermittent preventive treatment (IPT) - all students will receive treatment. Arm 3: Control - students will receive standard of care (no preventive treatment). Outcomes include P. falciparum infection and parasite density, gametocyte carriage and gametocyte density, anemia, cognitive function and educational testing, as well as infection prevalence in student's households to assess the impact on transmission.

Read the detailed description

Students will be enrolled in a single primary school in Machinga District, Malawi. The intervention will be conducted every 6-weeks during the two school terms which coincide with peak malaria transmission. Students in the IPT are and those that test positive in the IST arm will be treatment with dihydroartemisinin-piperaquine (DP) (females less than 10 years old and all males) or chloroquine (females 10 years old or older).

Model description
Students will be randomized to intermittent screening-and-treatment (IST - Arm 1), intermittent preventive treatment (IPT - Arm 2), or control with no preventive treatment (Arm 3). Females less that 10 years of age (pre-menarche) and all males will be treated with DP if they are in Arm 2 or test positive in Arm 1. Females 10 years and older will be treated with chloroquine if they are in Arm 2 or test positive in Arm 1.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Dihydroartemisinin-Piperaquine and Chloroquine in people with Malaria,Falciparum and Anemia in Children, run by University of Maryland, Baltimore at 1 site in Malawi.

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 7 inclusion and 9 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 15 Nov 2022. 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 Malawi. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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?

P. falciparum infection (time frame: 6-8 weeks after the last intervention). 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 NCT05244954, 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 15 Nov 2022.
