Study Details

Study Description

Brief Summary

The primary trial objective is to determine the clinically effective dose of orally administered pyronaridine/artesunate (Pyramax®, PA) with a 3:1 ratio to treat adults with acute, symptomatic, uncomplicated P. falciparum malaria in South East Asia and Africa. Secondary trial objectives are to determine the safety of once-daily dosing for 3 days of PA and to explore possible ethnic differences in safety or efficacy.

Condition or Disease Intervention/Treatment Phase
Phase 2

Detailed Description

This is a double-blind, multicentre, randomized, parallel group, dose-finding study of the efficacy, safety and tolerability of a once-daily 3-day regimen of PA with a 3:1 weight/weight ratio for patients with acute, symptomatic, uncomplicated P. falciparum malaria. Patients will be recruited from 5 to 7 study sites in endemic regions of South East Asia and Africa and will be randomized to 1 of 3 treatment groups differing in dosage, with 160 patients per group (n-480). Randomization will be balanced within each study site across all 3 study groups in pre-assigned treatment blocks.

The first dose will be administered on Day 0 and patients will remain hospitalized for at least 4 days whilst undertaking the 3-day regimen. Patients will remain near the study site for a minimum of 7 days or once fever and parasite clearance is confirmed (assessed by 3 negative readings of fever and/or slide).

The primary efficacy end point is the cure rate on Day 28 - the proportion of patients with PCR-corrected adequate clinical and parasitological response (ACPR). Despite this Day 28 end point, the relatively long half-life of pyronaridine necessitates follow-up until 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.

  • Outcome Measures

    Primary Outcome Measures

    1. PCR-Corrected ACPR at Day 28 [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

    Secondary Outcome Measures

    1. PCR-Corrected ACPR at Day 14 [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

    2. Parasite Clearance Time [Thick blood slides were examined every 8 hours until at least 72 hours or until a negative smear was recorded]

      Parasite clearance time was defined as the time (in hours) from first dosing to the time of first blood draw with parasite clearance. Parasite clearance is defined as zero presence of parasites for two consecutive negative readings eight hours apart, with confirmed negative reading at 24 hours after the first negative slide

    3. Fever Clearance Time [Every 8 hours for at least 72 hours after the first dose]

      Fever clearance time was defined as the time (in hours) from first dosing to the first normal reading with fever clearance (2 consecutive assessments without fever (<37.5°C)). The method of temperature measurement was the same (ie, axillary, tympanic, oral or rectal) for each subject. Any subjects with a documented history of fever at inclusion, but who did not subsequently have a documented temperature reading >37.5°C during the 24 hours after initial dosing, were not included in this end point analysis.

    4. Parasite Clearance [Days 1, 2, and 3]

      Parasite clearance is defined as zero presence of parasites for 2 consecutive negative readings 8 hours apart, with confirmed negative reading at 24 hours after the first negative slide. The proportion of subjects with parasite clearance was summarized at Days 1, 2, and 3.

    5. Fever Clearance [Days 1, 2 and 3]

      Fever clearance was defined as a subject without fever for 2 consecutive assessments, plus confirmed normal temperature at 24 hours. The proportion of subjects with fever clearance was summarized at Days 1, 2, and 3.

    6. Adverse Events (AEs) [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]

      An AE was defined as any unfavourable and unintended sign, symptom, syndrome, or illness that developed or worsened during the period of observation in the clinical study
