- Female subjects of childbearing potential must use adequate contraception
Exclusion Criteria:
- Life-threatening or fulminant CDI
- Subjects with 2 or more episodes of CDI in the previous year
- Females who are pregnant or breastfeeding
- History of inflammatory bowel disease

Arms of the Study
Arm 1
Arm 2
Arm Type
Experimental
Active Comparator
Arm Label
Ridinilazole (SMT19969)
Fidaxomicin
Arm Description
200 mg capsule of Ridinilazole (SMT19969) twice a day for 10 days
200 mg tablet of Fidaxomicin twice a day for 10 days
Outcomes
Primary Outcome Measures
Number of treatment emergent adverse events (AEs) and serious adverse events (SAEs) to evaluate safety and tolerability
Secondary Outcome Measures
To assess the pharmacokinetics of SMT19969 in patients with CDI by measuring the plasma, urine and fecal concentrations of SMT19969
To assess the qualitative and quantitative effect on the bowel flora of each subject using 16S ribosomal RNA sequencing, metagenomics and bioinformatic techniques
Measure clinical cure rates at the Test of Cure (TOC) visit
Investigator assessed clinical response at the TOC visit (on day 12) with clinical cure defined as the resolution of diarrhoea (≤ 3 Unformed Bowel Movements (UBMs) per day) while on treatment that is maintained until the TOC visit.
Measure sustained clinical response (SCR) rates
SCR is defined as clinical cure at TOC and no recurrence of CDI within 30 days post end of treatment (EOT).
