Brief Summary

Background: Children with acute malnutrition have immature gut microbial communities compared to age-matched children with healthy growth that can not be repaired by existing therapeutic foods (Subramanian et al., Nature. 2014). Hence, investigators' recent work in Bangladesh has focused on developing Microbiota-Directed Complementary Foods (MDCF) containing locally-available food ingredients, that repair the gut microbiota of children with acute malnutrition to a configuration that resembles that of healthy children living in the same urban community (Raman et al., Science 2019; Gherig et al., Science 2019). The investigators recently completed a randomized, controlled proof-of-concept (POC) study of current lead microbiota-directed complementary food, MDCF-2 compared to a standard ready-to-use supplementary food (RUSF), in Bangladeshi children with moderate acute malnutrition (MAM)(Chen et al., N Engl J Med 2021). Children who received MDCF-2 for 3 months exhibited significantly greater repair of their gut microbial communities and faster rates of ponderal growth compared to those treated with RUSF (a formulation that was not designed based on knowledge of its effects on the gut microbiota). The superior effect of MDCF-2 on gut microbiota repair and weight gain was even more notable as the RUSF was significantly more energy dense than MDCF-2. In the aforementioned POC study, MDCF-2 was prepared fresh daily in icddr,b field kitchens prior to distribution and supervised administration to study participants. The lack of a shelf-stable, bio-equivalent formulation of MDCF-2 limits the ability to perform larger studies in Bangladesh as well as in other geographic settings. This pre-POC study in Bangladeshi children with MAM will assess the bioequivalence of MDCF prototypes that the investigators have developed with the potential for improved storage stability compared to current MDCF-2, using the degree of microbiota repair after 4-weeks of treatment as the primary outcome. Objective: To develop a scalable, shelf-stable formulation that is bioequivalent to MDCF-2 with respect to microbiota repair in 8-12 month-old Bangladeshi children with MAM after 4-weeks of treatment. Methods: A 5-arm, randomized single-blind pre-POC study will be conducted in 8-12-month-old Bangladeshi children with MAM to compare the efficacy of alternative MDCF formulations in repairing their gut microbiomes compared to the repair produced by the current kitchen prepared MDCF-2 formulation. Arm 1 - Reference control: kitchen-prepared MDCF-2 Arm 2 - Ready-to-use supplementary food Arm 3 - Individually packaged, pre-measured sachets of MDCF-2 ingredients, combined and reconstituted in the home setting prior to consumption. Arm 4 - MDCF-2 shelf-stable foil pouch formulation with green banana powder. Arm 5 - MDCF shelf-stable foil pouch formulation with sweet potato instead of green banana.

Outcome Measures

Primary Outcomes (1)

  • Equivalence in the response to MDCF-2 and a test MDCF formulation, based on the change in representation of gut bacterial taxa after 4-weeks of treatment with MDCF-2, compared to the change after treatment with the test MDCF for 4-weeks.

    V4-16S rDNA amplicons and shotgun sequencing datasets will be generated from fecal samples collected from each child in each group prior to, during, and after treatment to determine the abundances of MDCF-2 responsive bacterial taxa. Equivalence will be defined as the absence of a statistically significant difference after 4-weeks of treatment in the representation of fecal bacterial taxa associated with the response to MDCF-2 in participants receiving a test MDCF, compared to the representation of these bacterial taxa in participants after receiving the reference MDCF-2 formulation for 4-weeks.

    Baseline to 4-weeks of treatment.

Other Outcomes (2)

  • Changes in the abundances of 7000 circulating plasma proteins

    Baseline to end of Week 4

  • Changes in the concentrations of fecal protein biomarkers of gut inflammation

    Baseline to end of Week 4
