Outcome Measures

Primary Outcomes (2)

  • Safety and tolerability of SER-262 as assessed by incidence of AEs, lab results, vital signs, ECG, and physical examination findings

    Up to 24 weeks after treatment

  • Relative risk of recurrence based on the proportion of subjects experiencing CDI recurrence in each SER-262 cohort compared to placebo up to 8 weeks after treatment

    Up to 8 weeks after treatment

Secondary Outcomes (2)

  • Time to recurrence of CDI

    Up to 24 weeks after treatment

  • Relative risk of recurrence of CDI up to 4, 12, and 24 weeks after treatment

    Up to 4, 12, and 24 weeks after treatment

Study Arms (2)

SER-262

EXPERIMENTAL

SER-262 \[Single dose: 10(4), 10(5), 10(6), 10(7) or 10(8) SCFUs; Multiple dose 10(6), 10(7), or 10(8) SCFUs\]

Drug: SER-262

Placebo

PLACEBO COMPARATOR

Placebo

Drug: Placebo

Interventions

SER-262 is a rationally designed, multi-strain Ecobiotic® microbiome therapeutic produced synthetically by in vitro fermentation. It is a consortium of anaerobic, commensal bacteria in spore form, encapsulated for oral administration.

Also known as: Cultivated Eubacterial Spore Suspension, Encapsulated
SER-262

Placebo will be identical to the investigational product but will not contain product spores or non-spore solids. Placebo will consist of 92% glycerol and 8% normal saline.

  • History of inflammatory bowel disease (ulcerative colitis, Crohn's disease, microscopic colitis) with diarrhea believed to be caused by active inflammatory bowel disease in the past 12 months.
  • Estimated glomerular filtration rate (eGFR) \< 60 ml/min/1.73m2
  • Admitted to or expected to be admitted to an intensive care unit for medical reasons (not just boarding). Patients discharged from an intensive care unit before Day 1 may be enrolled.
