Study summary

The purpose of the study is to determine whether the artesunate-amodiaquine combination is effective in treating uncomplicated Plasmodium falciparum malaria in children with severe acute malnutrition.

Infection with Plasmodium falciparum malaria remains a significant cause of morbidity and mortality in malnourished children. Malnutrition is known to have a modulating effect on the incidence of malaria infections, its severity and effectiveness of treatments. However, little data exists on antimalarial drug efficacy in malnourished children. Artesunate-amodiaquine combination is the first line treatment used in Médecins Sans Frontières programmes in Niger. The assumption of current efficacy of artesunate-amodiaquine is based on non malnourished children. The aim of this study is to measure the clinical and parasitological efficacy in severely malnourished children.

The study is consistent with the standard WHO protocol for monitoring antimalarial drug efficacy (WHO: Methods for surveillance of antimalarial drug efficacy. Geneva; 2009), except for one inclusion criterion. Severe acute malnutrition is an inclusion criteria, instead of being an exclusion criteria. The study will encompass a pharmacokinetic part that will provide important information on the absorption of the drug.

Inclusion criteria

  • Age between 6 and 59 months
  • Weight ≥5kg
  • P. falciparum monoinfection confirmed on a thick blood film
  • Parasitic density between 1,000 and 200,000 asexual forms/uL of blood
  • Measured axillary temperature ≥37.5°C or history of fever during the previous 24 hours
  • Severe malnutrition (defined as a weight/height ratio less than -3 z-scores)
  • High probability of compliance with follow-up visits (home is within two hours of walk from the outpatient department, no near-term travel plans, etc..)
  • Consent of a parent or guardian who is at least 18 years of age.

Exclusion criteria

Exclusion Criteria:

  • Signs of a critical illness as defined by the WHO (WHO (2000) Severe falciparum malaria; Clinical features of severe falciparum malaria in children. Royal Society of Tropical Medicine and Hygiene, 94 (supplement 1), 5-11).
  • Signs of severe or complicated malaria as defined by the WHO (WHO (2000) Severe falciparum malaria; Clinical features of severe falciparum malaria in children. Royal Society of Tropical Medicine and Hygiene, 94 (supplement 1), 5-11).
  • Severe anaemia ( \<5 g/dL)
  • Known history of to any of the study medications,
  • Symmetric oedema in the feet,
  • Concomitant febrile illness not originating from malaria, which could alter the outcome of the study (measles, acute lower respiratory tract infection, otitis media, tonsillitis, abscesses, severe diarrhea with dehydration, etc.),
  • History of a full treatment course with the study drug in the past 28 days.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
