The purpose of the study is to evaluate the efficacy and safety of lyophilized PRIM-DJ2727 capsules given orally in subjects with ulcerative colitis at remission stage. This study will also include longitudinal analyses of recipient's gut microbiota taxonomy and metagenomics to determine potential associations with clinical outcomes in context of active FMT or placebo administration.

Arm Groups

ArmDescriptionAssigned Intervention
Patients with UC will receive FMT capsules
Patients with ulcerative colitis will receive fecal microbiota capsules from 3 healthy donors
  • Drug: PRIM-DJ2727
    Fecal Microbiota Transplantation (FMT) product manufactured as PRIM-DJ2727 capsules consists of lyophilized microbiota suspension from well-screened donors. Microbiota from three donors will be combined to make the product.
Placebo Comparator
Patients with UC will receive placebo
Patients with ulcerative colitis will receive matching placebo capsules. Placebo capsule will be identical to PRIM-DJ2727 but will not contain intestinal bacteria.
  • Drug: Placebos
    Placebo capsule will be identical to PRIM-DJ2727 but will not contain intestinal bacteria.
