About this study

Official title: An Active Malaria Epidemiology Cohort Study With Evaluation of a 2 Day Versus 3 Day Treatment Regimen of Dihydroartemisinin (DHA)-Piperaquine for Patients With Uncomplicated Malaria

An observational cohort and malaria treatment study in Cambodia.

Read the detailed description

This is an active observational Cohort Study of malaria epidemiology with a nested two arm, randomized, open label Treatment Study comparing the efficacy, safety, tolerability and pharmacokinetics of a two versus three day course of Dihydroartemisinin-Piperaquine (DP) for those developing uncomplicated malaria. At the conclusion of the Cohort Study, a subset of volunteers with documented exposure to Plasmodium vivax during the study will be treated with primaquine as presumptive anti-relapse therapy directed against the exoerythrocytic malaria stages of P. vivax, and followed passively for an additional 6 months.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Dihydroartemisinin piperaquineDrug

    Also called Artekin, Duo-cotexcin

    40/320 mg tablets, 9 tablets total

Study groups in NCT01280162
Study groupRoleWhat they receive
3 day therapyExperimentalTotal dose split over 3 days (3 tablets per day)
Receives: Drug: Dihydroartemisinin piperaquine
2 day therapyExperimentalTotal dose split over 2 days (4.5 tablets per day)
Receives: Drug: Dihydroartemisinin piperaquine

What is being measured

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

  1. Adequate clinical and parasitological response to a treatment regimen of DHA-PIP for Plasmodium falciparum

    Number of malaria recurrences for 2 and 3 day DHA-PIP drug regimens within 42 days after treatment of malaria infection, diagnosed by positive PCR-corrected malaria microscopy.

    Measured: 6 months

Secondary outcomes (2)
  1. Number of Cambodian study subjects with reduced or null activity hepatic cytochrome P450 2D6 alleles

    Using Polymerase Chain Reaction-based bead array assays, genotype the human hepatic CYP2D6 allele in study participants giving informed consent for genetic testing

    Measured: 1 year

  2. Number of subjects with reduced or null hepatic CYP2D6 enzyme phenotype using activity-score A system

    For each CYP2D6 genotype determined, use the AS-A system to assign predicted metabolism phenotype

    Measured: 1 year

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Mar 2021. 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 Cambodia. 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.

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?

Adequate clinical and parasitological response to a treatment regimen of DHA-PIP for Plasmodium falciparum (time frame: 6 months). 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 NCT01280162, which also lists 4 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 3 Mar 2021.
