Efficacy, Safety and Pharmacokinetic of ArtequinTM P. Falciparum Malaria

Treatment of Plasmodium falciparum malaria in Africa is increasingly difficult. Resistance to cheap efficient antimalarial drugs poses an increasing threat. The rapid emergence of resistance to sulfadoxine - pyrimethamine, already seen in East Africa is growing and is likely to have an striking impact on mortality in many other African regions where no obvious alternatives are available. WHO recommends the use of drug combinations containing artemisinin compounds, i.e., artemisinin-based combination therapies (ACT). Previous clinical trials have shown that the combination of artesunate with mefloquine is highly effective and well tolerated in the treatment of multidrug-resistant falciparum malaria, retaining the benefit of rapidity of action while augmenting cure rates, and apparently slowing the development of mefloquine resistance. Compliance with sequential combination regimen of antimalarial drugs is notoriously poor. Therefore, in order to limit the development of resistance to both drugs and ameliorate patients' compliance to antimalarial treatments, an optimal simultaneous combination regimen of artesunate and mefloquine in a practical single blister pack has been developed by Mepha Ltd. and successfully tested.

About this study

Artequin dosages could only be tested in children able to swallow tablets and with a body weight of more than 20 kg. However, there is a great need for an Artequin formulation for smaller children unable to swallow tablets. The new Artequin Paediatric oral formulation is a flavoured, taste-masked preparation of granules of 50 mg artesunate and 125 mg mefloquine as a fixed-dose combination (once daily in one single Stickpack, i.e. 3 Stickpacks for a 3-day treatment). It is suitable for children with up to 20 kg body weight (with a range of 10-20 kg).

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Male or female with a body weight ≥10 to 40 kg

  • Patients suffering from acute uncomplicated Plasmodium falciparum malaria
  • Malaria diagnosis confirmed by a positive blood smear with asexual forms of Plasmodium falciparum (i.e., identification of asexual parasite count ≥1,000 to 250,000 per mm3)
  • Ear temperature 37.5°C or a history of fever within the last 48 hours
  • Haemoglobin 7g/100ml
  • Written informed consent and written consent from parents/guardian for children below age of consent (verbal consent in presence of literate witness is required for illiterate patients or parents/guardians).

Exclusion criteria

Patients with signs and symptoms of severe/complicated malaria requiring parenteral treatment (defined according to WHO Recommendations "Malaria Control Today", RBM Working Document, March 2005, see Appendix 2)

  • Patients with known hypersensitivity or allergy to artemisinin derivatives or mefloquine or mefloquine chemically related compounds (for example quinine and quinidine)
  • Patients who had received quinine or any artemisinin derivatives within 12 hours prior to study start
  • Patients who had received any other adequate antimalarial drug therapy including antibiotics which might be active against malaria infection within 1 week prior to study start
  • Patients who had received investigational (unlicensed) drugs as well as mefloquine within 30 days prior to study start
  • Patients with known history of psychiatric disorders
  • Patients with known history of cardiac diseases and arrhythmia
  • Patients with known sickle cell disease
  • Patients with clinical signs of or laboratory evidence for any other severe hepatic, renal, pulmonary, cardiac, metabolic, psychiatric, cancer or haematologic diseases
  • Pregnancy or lactation
