Pyronaridine Artesunate 3:1 Granule Formulation vs. Coartem© Crushed Tablets in P. Falciparum Malaria Pediatric Patients
Phase III Comparative, Open-Labelled, Randomised, Clinical Study to Assess a Fixed Dose of Oral Pyronaridine Artesunate Granule Formulation vs. Coartem® Crushed Tablets in Infants With Acute Uncomplicated Plasmodium Falciparum Malaria
  • The primary objective of this clinical study is to demonstrate the efficacy of the fixed combination of pyronaridine artesunate granule formulation (60:20 mg; paediatric PYRAMAX®) by showing a PCR-corrected adequate clinical and parasitological cure rate of more than 90%.
  • Treatment success or failures will be classified according to WHO Guidelines 2005

The need for safe and efficacious anti-malarial treatments for infants and children is huge given that they are the major group affected by acute uncomplicated malaria. There are relatively few paediatric formulations of artemisinin combination therapies. In addition to the tablet formulation of pyronaridine artesunate (PA) (PYRAMAX), Shin Poong Pharm Co is developing a paediatric dosing form presented as a granule formulation, packed in appropriate aluminium sachets each containing 60mg pyronaridine tetraphosphate and 20mg artesunate.

This Phase III study is designed to demonstrate that the efficacy of PA granule formulation, as assessed in terms of PCR-corrected APCR, is above 90% and subsequently to compare (non-inferiority) the efficacy and safety of PA granule formulation to Coartem® crushed tablets in infants and children.

Phase 3
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
  • Drug: pyronaridine artesunate
    The strength of the granule formulation is 60:20 mg pyronaridine artesunate per sachet. Depending on their body weight, patients will receive between 1 to 3 pyronaridine artesunate sachets per day, for 3 consecutive days The actual dose-range covered by this regimen is 7.0:2.3 mg/kg to 13.3:4.4 mg/kg pyronaridine artesunate, which has shown to be effective and safe in the phase II studies conducted in children and adults.
    Other Name: Pyramax
  • Drug: arthemeter lumefantrine

    Artemether 20 mg and lumefantrine 120 mg fixed dose combination, 6 dose regimen 120 mg artemether and 720 mg lumefantrine total (Novartis).

    The posology is twice daily for 3 consecutive days 1 tablet for patients weighing ≥5 kg to <15 kg, 2 tablets for patients weighing ≥15 to <25 kg.

    Other Name: Coartem
  • Experimental: 1
    60mg pyronaridine and 20mg artesunate fixed dose combination granule formulation for 3 consecutive days
    Intervention: Drug: pyronaridine artesunate
  • Active Comparator: 2
    120mg lumefantrine and 20mg Artemether fixed dose combination crushed tablets, twice a day for 3 days
    Intervention: Drug: arthemeter lumefantrine
