Relationship of engraftment of SER-109 species to dose administered in the phase 1 and phase 2 studies. Subjects receiving the high dose, as defined by SporQ (see Methods), in the open-label phase 1 dose-ranging study (SERES- 001) had significantly more SER-109 species than subjects in the treatment arm of the phase 2 study (SERES-004), who received a fixed dose (wk1; P < .0001, Mann-Whitney U test). The number of SER-109 species was not significantly different between subjects receiving the low dose in the phase 1 trial and subjects receiving the fixed dose in the phase 2 trial (Mann-Whitney U test). The number of SER-109 species stratified by treatment and time point is shown; dots represent outliers. Sample sizes are shown below the x axis. ***P < .0001. Abbreviations: BL, baseline; ns, nonsignificant; wk1, week 1.
