Brief Summary:
This study will evaluate the safety and tolerability of IMM-529 together with standard of care (SOC) in patients with Clostridium-difficile Infection.

Condition or disease Intervention/treatment Phase
Clostridium Difficile Infection Clostridium Difficile Infection Recurrence Biological: IMM-529 Other: Placebo Phase 1 Phase 2

Detailed Description:

Subjects who provide voluntary written informed consent will be screened for eligibility. Subjects meeting all of the inclusion and none of the exclusion criteria will be eligible to participate.

Eligible subjects will be randomized up to 3 weeks post diagnosis of Clostridium-difficile Infection given SOC initiated already.

Each subject will return to the study clinic for assessment and required study procedures on Day 7, Day 14, Week 4, Week 8 and Week 12 post randomization. Treatment duration will be 28 days and follow up will last up to 12 weeks post randomization.
