SP Resistance and Falciparum Malaria Transmission
A Phase 3 study testing sulfadoxine/pyrimethamine in people with Plasmodium Falciparum Malaria, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 sites in Colombia.
Trial summary
The purpose of this study is to study resistance to current malaria treatments and affordable alternatives for uncomplicated malaria. Resistance occurs in areas where these treatments are used frequently. This study may help prevent future resistance. About 150 residents in Buenaventura, Colombia will participate.

About this study
Official title: SP Resistance Markers and Falciparum Malaria Transmission
The purpose of this study is to study resistance to current malaria treatments and affordable alternatives for uncomplicated malaria. Resistance occurs in areas where these treatments are used frequently. This study may help prevent future resistance. About 150 residents in Buenaventura, Colombia will participate. They will have uncomplicated malaria and they will be followed for 28 days after treatment. Physical exams and blood draws are included in study visits.
Read the detailed description
Drug-resistant Plasmodium falciparum is a major threat to global public health and new strategies are needed to deter spread of resistance to available and forthcoming antimalarial drugs. This study seeks to contribute to understanding the molecular basis of spread of drug resistance in a setting with low level of sulfadoxine-pyrimethamine (SP) treatment failure. The objectives of this study are to compare the prevalence of dihydrofolate reductase (DHFR) and dihydropteroate synthase (DHPS) point mutations associated with SP resistance before and after SP treatment of uncomplicated Plasmodium falciparum malaria episodes and to measure parasite infectivity to Anopheles mosquitoes of post-treatment gametocytes with and without DHFR and DHPR mutations. Patients with uncomplicated falciparum malaria will receive a standard SP regimen and will be closely followed for 28 days. This study will add new knowledge of the understanding of ways in which resistance is spread and is expected to provide a sound basis for the future clinical evaluation of antimalarial drug combinations designed to prevent transmission of drug-resistance malaria.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing sulfadoxine/pyrimethamine in people with Plasmodium Falciparum Malaria, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 sites in Colombia.
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 1 inclusion and 1 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: withdrawn, as of the sponsor's last update on 30 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Colombia. 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 was withdrawn before enrolling participants, so there are no results.
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.
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 30 Jan 2019; AzTrials last refreshed its copy on 7 Nov 2026.
