About this study
Official title: Phase 3a: Efficacy, Safety, and Tolerability of Dihydroartemisinin/Piperaquine (Artekin®) for the Treatment of Uncomplicated Plasmodium Falciparum Malaria in the Peruvian Amazon Region
In Peru, Mefloquine plus Artesunate (MAS3), is the current first line treatment for P. falciparum malaria in the Amazonian Region, and has proved its efficacy against multi-resistant P. falciparum parasites, but several side effects have been reported. Dihydroartemisinin-piperaquine (DHA-PPQ) is a new co-formulated and well tolerated ACT, increasingly used in Southeast Asia where it has proved to be highly effective against Plasmodium falciparum malaria. We tested the efficacy, safety and tolerability of DHA-PPQ in patients with uncomplicated P. falciparum malaria. A RCT to evaluate DHA-PPQ was carried out, between 2003 and 2005. Patients with uncomplicated P. falciparum malaria were randomly allocated to receive either DHA-PPQ or MAS3 with a 63-day follow-up period. Five hundred twenty two patients were included in the analysis, 262 were allocated to receive DHA-PPQ, and 260 to receive MAS3. The two groups were comparable at baseline in demographic and clinical characteristics. The mean time for parasite clearance into the DHA-PPQ group was 32.0 hours and 35.5 hours in the MAS3 group. Twenty-four hours after the first dose, the proportions of patients whose cleared parasitaemia were 67.2% in the DHA-PPQ group, and 58.1% in the MAS3 group (RR 1.25, [95% CI 1.03-1.52], p = 0.017). All patients were able to clear parasites within 72 hours after the first dose. The mean time for fever clearance was 28.0 and 29.5 hours in DHA-PPQ and MAS3 group respectively. (P= 0.69). Twenty-four hours after the first dose, 85.5% and 83.1% of patients cleared fever in the DHA-PPQ and MAS3 group respectively (p>0.05). The Adequate Clinical and Parasitological Response (ACPR), PCR adjusted, were 97.7% and 99,2% for the DHA-PPQ and MAS3 group respectively, (RR 0.99, 95% CI [0.86-1.13], P = 0.88). No Early Treatments Failures were reported in any group. In the DHA-PPQ group, according to the PCR adjusted results, 6 subjects had Late treatment Failures. In the MAS3 group, two Late Treatment Failures was reported. The frequency of adverse events was significantly lower in patients treated with DHA-PPQ than in those treated with MAS3.
DHA-PPQ proved to be a highly effective antimalarial drug for the treatment of P. falciparum malaria and suitable for use in the Peruvian Amazon region. It also has the advantage of being better tolerated. In terms of cost, DHA-PPQ is cheaper and more affordable than MAS3 and should be considered for the National Antimalarial Drug Policy in Perú.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Dihydroartemisin-piperaquine and Mefloquine + Artesunate in people with Malaria, run by Institute of Tropical Medicine, Belgium.
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 13 inclusion and 0 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 14 Sep 2010. Status can change between updates, so confirm with the study contact before making plans.
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?
Adequate Clinical and parasitological response (time frame: Day 63). 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 NCT00373607, which also lists 1 linked publication.
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 14 Sep 2010.
