About this study

Official title: A Phase III Comparative, Open-label, Randomised, Multi-centre Study to Assess the Efficacy of Pyronaridine Artesunate (180:60mg) Versus Mefloquine (250mg) Plus Artesunate (100mg) in Children & Adult Patients With Acute Falciparum Malaria

The primary objective of this phase III clinical study is to compare the efficacy and safety of the fixed combination of pyronaridine artesunate (Pyramax®, PA) with that of the combination of mefloquine plus artesunate (MQ + AS) in children and adults with uncomplicated P falciparum malaria in South East Asia, India and Africa.

Read the detailed description

This is a multi-centre, comparative, randomised, open-label, parallel-group, non-inferiority study comparing the efficacy and safety of a fixed combination of PA to a loose combination of MQ + AS for patients with acute, symptomatic, uncomplicated P. falciparum malaria. The study population will include 1271 patients, comprising male and female children (≥20 kg body weight) and adults, recruited from study sites in South East Asia, India and Africa. Patients will be randomised in a 2:1 ratio to receive either oral PA (180:60mg tablets) or MQ (250mg tablets) plus AS (100mg tablets) once a day for 3 consecutive days (Days 0, 1, and 2). The study drug will be administered by a Third-Party Investigator unblinded to the study treatment, while the Investigator remains blinded.

Patients will be confined to the to the study facility for ≥4 days (Days 0, 1, 2, and 3) and 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 proportion of patients with PCR-corrected adequate clinical and parasitological response (ACPR) on Day 28. 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.

The primary efficacy end point for the study is the proportion of subjects with PCR-corrected adequate clinical and parasitological response (ACPR) on Day 28 (defined as the absence of parasitaemia without the subject's meeting any of the criteria of early treatment failure, late clinical failure, or late parasitological failure). 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.

What is being measured

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

  1. Percentage of Subjects With PCR-corrected Adequate Clinical and Parasitological Response (ACPR) on Day 28

    Percentage of subjects with PCR-corrected adequate clinical and parasitological response (ACPR) on Day 28, defined as absence of parasitaemia on Day 28 without the subject's meeting any of the criteria of early treatment failure, late clinical failure, or late parasitological failure.

    Measured: Day 28

Secondary outcomes (7)
  1. PCR-corrected ACPR on Day 14

    Percentage of subjects with PCR-corrected adequate clinical and parasitological response (ACPR) on Day 14, defined as absence of parasitaemia on Day 14 without the subject's meeting any of the criteria of early treatment failure, late clinical failure, or late parasitological failure

    Measured: Day 14

  2. Crude ACPR on Days 14 and 28

    Percentage of subjects with adequate clinical and parasitological response (ACPR) on Days 14 and 28, without correction by PCR, defined as absence of parasitaemia on Days 14 and 28 without the subject's meeting any of the criteria of early treatment failure, late clinical failure, or late parasitological failure

    Measured: Days 14 and 28

  3. Parasite Clearance Time

    Parasite clearance time was defined as the time from first dosing to time of first blood draw with parasite clearance. Parasite clearance was defined as zero presence of asexual parasites for 2 consecutive negative readings taken between 7 and 25 hours apart.

    Measured: Thick blood films were examined every 8 hours until ≥72 hours or until 2 consecutive negative readings occurred 7 to 25 hours apart, and on Days 3, 7, 14, 21, 28, 35, and 42 (or any other day if the subject returned).

  4. Fever Clearance Time

    Fever clearance time was defined as the time from first dosing to first normal reading of temperature (<37.5°C taken axillary or tympanic; <38°C taken oral or rectal) for 2 consecutive normal temperature readings taken between 7 and 25 hours apart.

    Measured: Every 8 hours over ≥72 hours following first study drug administration or temperature normalisation for ≥2 readings between 7 and 25 hours apart, then at each visit.

  5. Parasite Clearance at Day 1, 2 and 3

    Parasite clearance time was defined as the time from first dosing to the time of first blood draw with parasite clearance. Parasite clearance was defined as zero presence of asexual parasites for 2 consecutive negative readings taken between 7 and 25 hours apart.

    Measured: Days 1, 2 and 3

  6. Fever Clearance at Day 1, 2 and 3

    Fever clearance time was defined as the time for at least 2 consecutive normal body temperature measurements (<37.5°C axillary/tympanic or <38.0°C oral/rectal) to be obtained within an interval of 7 to 25 hours post-dosing.

    Measured: Days 1, 2 and 3

  7. Adverse Events and Clinically Significant Laboratory Results

    Cases and severity of adverse events and of 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 Mefloquine plus artesunate in people with Falciparum Malaria, run by Medicines for Malaria Venture at 9 sites in 7 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 7 inclusion and 14 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 9 sites in Thailand, Vietnam, Burkina Faso, Cambodia, Côte d’Ivoire and 2 more countries. 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 17 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?

Percentage of Subjects With PCR-corrected Adequate Clinical and Parasitological Response (ACPR) on Day 28 (time frame: Day 28). 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 NCT00403260, 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.
