Arm Intervention/treatment
KB109 + Self Supportive Care (SSC) Other: KB109 + Self Supportive Care (SSC)
KB109 is a novel glycan

Self Supportive Care (SSC) Alone Other: Self Supportive Care (SSC) Alone
Self Supportive Care (SSC) Alone

Primary Outcome Measures :
  1. Number of patients experiencing study-product related treatment-emergent adverse events (TEAEs) [ Time Frame: Day 1 to Day 35 ]

Secondary Outcome Measures :
  1. Relative abundance of microbial taxa in fecal samples as assessed by shotgun profiling based on shotgun sequencing. [ Time Frame: Day 1 to Day 35 ]
    Change from baseline in relative abundance of microbial taxa (operational taxanomic units) in the KB109 + SSC group versus SSC alone
