Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Evaluate the clinical outcome by assessment of sustained clinical response [ Time Frame: 30 days post End of Therapy ]
    Sustained clinical response is defined as clinical cure at the Test of Cure Visit (Day 12) and no recurrence of CDAD within 30 days of End of Therapy


Secondary Outcome Measures :
  1. Plasma and faecal concentrations of SMT19969 [ Time Frame: 40 Days ]
    Using laboratory analysis

  2. To assess the safety and tolerability of SMT19969 compared with vancomycin [ Time Frame: 40 days ]
    Assessment of the Adverse Events (AEs) and Serious Adverse Events (SAEs) reported within the study


Other Outcome Measures:
  1. To assess the qualitative and quantitative effect of SMT19969 and Vancomycin on the bowel flora of subjects [ Time Frame: 40 days ]
    Using microbiology, sequencing, metagenomic and bioinformatics techniques.
