Composition of fecal microbiota (16S ribosomal ribonucleic acid (rRNA) gene sequencing) was measured at Week 0, Week 8, and Week 56. Fecal bacterial composition was determined using 16S sequencing. The obtained sequences were analyzed using the Ezbiocloud database and 16S microbiome pipeline to assess composition and diversity.

This endpoint was not completed due to lack of data collection.
