About this study
Official title: A Phase III Comparative (Double-blind, Double-dummy) Randomised Multicentre Study to Assess the Safety & Efficacy of Oral Pyronaridine Artesunate (180:60 mg) Versus Chloroquine (155 mg) in Children & Adult Patients With Acute Vivax Malaria
The purpose of this study is to compare the efficacy and safety of the fixed combination of pyronaridine artesunate (Pyramax®, PA) (180:60 mg) with that of standard chloroquine therapy in children and adults with acute, uncomplicated Plasmodium vivax malaria.
Read the detailed description
This is a multi-centre, randomised, double-blind, double-dummy, parallel-group, non-inferiority study comparing the efficacy and safety of the fixed combination of pyronaridine/artesunate (ie, PP/AS [PA]) (180:60 mg) with that of standard chloroquine therapy in children and adults with acute uncomplicated P. vivax malaria. The study population will include 456 patients, comprising male and female children (≥20 kg body weight) and adults recruited from study sites in South East Asia and India.
Patients will be randomised in a 1:1 ratio to receive either oral PA (180:60 mg tablets) plus chloroquine-placebo or oral chloroquine (155 mg tablets).plus PA-placebo, once a day for 3 consecutive days (Days 0, 1, and 2). For PA, posology was based on body weight ranges with subjects receiving 1 to 4 tablets depending on their body weight. The dose range covered by this regimen is 7.2:2.4 mg/kg to 13.8:4.6 mg/kg, which has been shown to be effective and safe in Phase I and II studies. The chloroquine daily dose is 10 mg/kg on Days 0 and 1 and 5 mg/kg on Day 2 for children, and 620 mg on Days 0 and 1 and 310 mg on Day 2 for adults.
Patients will be confined to the study facility for ≥4 days (Days 0,1,2 \& 3) and ideally remain near the study site for ≥7 days, or once fever and parasite clearance has been confirmed for ≥24 hours - whichever occurs later.
The primary efficacy end point for the study is the crude cure rate on Day 14, which is defined as the absence of P. vivax parasitaemia on Day 14. Scheduled follow-up visits will continue until completion of the study at Day 42. In the case of adverse events reported and unresolved at Day 42, patients will be followed up for a further 30 days, or until resolution of the event.
For patients who complete the study up to Day 28 and who have normal glucose-6-phosphate dehydrogenase (G-6-PD) activity, a 14-day course of primaquine (15 mg/day for adults and 0.3 mg/kg/day for children) will be administered starting on Day 28 to complete their radical cure. Subjects who are deficient in G-6-PD and who completed the study up to Day 28 will be treated per country policy.

What is being measured
The primary outcome is the main question the study is designed to answer.
Crude Cure Rate on Day 14
Cure rate on Day 14 is defined as the absence of P. vivax parasitaemia on Day 14 irrespective of temperature (axillary, oral, tympanic, rectal) without previously meeting any of the criteria of treatment failure throughout the follow-up period.
Measured: Day 14
Secondary outcomes (6)
Crude Cure Rate on Days 21 and 28.
Cure on Day 21 and 28 is defined as the absence of P. vivax parasitaemia on Day 21 and 28 irrespective of temperature (axillary, oral, tympanic, rectal) without previously meeting any of the criteria of treatment failure throughout the follow-up period.
Measured: Day 21 and 28
Parasite Clearance Time
Parasite clearance time is defined as the time from first dosing to the time of first blood draw with parasite clearance. Parasite clearance is defined as zero presence of asexual parasites for 2 consecutive negative readings taken between 7 and 25 hours apart.
Measured: Days 0 to 42
Fever Clearance Time
Fever clearance time is defined as the time from first dosing to the first normal reading of temperature (<37.5°C for axillary/tympanic or <38°C for oral/rectal) for 2 consecutive normal temperature readings taken between 7 and 25 hours apart.
Measured: Days 0 to 42
Percentage of Subjects With Parasite Clearance on Days 1, 2, and 3
Percentage of subjects with parasite clearance on Day 1 (24 hours after first dose), Day 2 (48 hours after first dose), and Day 3 (72 hours after first dose).
Measured: Days 1, 2, and 3
Percentage of Subjects With Fever Clearance on Days 1, 2, and 3
Percentage of subjects with fever clearance on Day 1 (24 hours after first dose), Day 2 (48 hours after first dose), and Day 3 (72 hours after first dose).
Measured: Day 1, 2, and 3
Number of Participants With Adverse Events
Number of participants with adverse events, including clinically significant laboratory results, ECG, vital signs or physical examination abnormalities.
Measured: Day 0 to 42. Subjects experiencing AEs at Day 42 were followed for up to 30 days after the end of study or resolution of the event, whichever was earlier

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Pyronaridine artesunate and Chloroquine in people with Malaria, run by Medicines for Malaria Venture at 5 sites in 4 countries.
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 8 inclusion and 15 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 2 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 5 sites in Thailand, Cambodia, India, Indonesia. 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?
Yes. Results are posted in the registry (first posted 20 Sep 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Crude Cure Rate on Day 14 (time frame: Day 14). 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 NCT00440999, 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 2 Nov 2021.
