Effectiveness of a microbiota-targeted food to promote programmatic and sustainable nutritional recovery in children with uncomplicated acute malnutrition


  • Frequent relapses
  • Gut microbiota could be a target to decrease the risk of relapse
  • Proof of concept in Bangladesh (Chen et al, 2021): Promising results in limited sample
  • Evidence needed from larger randomized trials to show efficacy of an ACM on cure in children with SAM and MAM in other settings.


Primary objective

To evaluate the efficacy of a microbiota-targeted food (MFA) in terms of recovery in the program within 12 weeks and sustained recovery within 24 weeks of admission in children with uncomplicated acute malnutrition in Niger compared with standard ready-to-use therapeutic foods (RTTP) for SAM and standard supplementary ready-to-use foods (SRTP) for AMM.


Secondary objectives

  • Efficacy in terms of nonresponse and program dropout
  • Safety in terms of hospitalization, mortality, and serious adverse events
  • Effect on child anthropometry and neurocognitive development
  • Acceptability and use of the products in the home
  • Cost-effectiveness




Individually randomized controlled trial stratified by severity of acute malnutrition.

  • 2 MAS arms: ACM vs ATPE (Plumpy'nut)
  • 2 MAS arms: ACM vs ASPE (Plumpy'sup)
