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. Proportion of participants with endoscopic response on flexible sigmoidoscopy after 8 weeks of treatment with VE202 or placebo. [ Time Frame: 8 Weeks ]
    Endoscopic response is defined as a reduction from baseline of 1 point or more in Mayo endoscopic subscore. The Mayo endoscopic subscore is evaluated on a scale of 0 to 3, with a higher score representing more severe disease.

  2. Percentage of participants with Grade ≥ 3 Treatment-Emergent Adverse Events (TEAEs) that are treatment-related or Serious Adverse Events (SAEs) that are treatment-related in Part 1 and Part 2 of the study. [ Time Frame: 16 Weeks ]
    The safety of VE202 and placebo in Parts 1 and 2 of the study, which include an 8-week and 2-week course of treatment, respectively, will be evaluated.


Secondary Outcome Measures :
  1. Percentage of participants with endoscopic response on flexible sigmoidoscopy at Week 8, following treatment with VE202 for 2 weeks. [ Time Frame: 8 Weeks ]
    Endoscopic response is defined as a reduction from baseline of 1 point or more in Mayo endoscopic subscore. The Mayo endoscopic subscore is evaluated on a scale of 0 to 3, with a higher score representing more severe disease.

  2. Number of participants with TEAEs, SAEs, and Adverse Events of Special Interest (AESIs) in Parts 1, 2, and 3 of the study. [ Time Frame: 52 Weeks ]
    The safety of VE202 and placebo in Parts 1, 2, and 3 of the study, which include an 8-week and 2-week course of treatment followed by a long-term follow-up period, will be evaluated. AESIs are defined as treatment-related Grade ≥2 TEAEs that are gastrointestinal or bacterial infections.

  3. Percentage of participants with clinical remission at Week 8 of Part 1 and Week 8 of Part 2. [ Time Frame: 8 Weeks ]
    Participants will receive 8 weeks of VE202/placebo in Part 1 and 2 weeks of VE202/placebo in Part 2. Clinical remission is defined as attaining a Mayo stool frequency subscore of ≤1 and an improvement in stool frequency subscore of ≥1 point from baseline, a rectal bleeding subscore of 0 and an endoscopic subscore ≤1. Each component of the Mayo score is evaluated on a scale of 0 to 3, with a higher score representing more severe disease.

  4. Percentage of participants with clinical response at Week 8 of Part 1 and Week 8 of Part 2. [ Time Frame: 8 Weeks ]
    Participants will receive 8 weeks of VE202/placebo in Part 1 and 2 weeks of VE202/placebo in Part 2. Clinical response is defined as having met the definition of clinical remission or having a decrease from baseline of ≥2 points and a decrease of ≥30% in modified Mayo score, with either a rectal bleeding score of 0 or a decrease in rectal bleeding of ≥1 point. Each component of the modified Mayo score (stool frequency, rectal bleeding, endoscopy findings) is evaluated on a scale of 0 to 3, with a higher score representing more severe disease.

  5. Percentage of participants with endoscopic remission on flexible sigmoidoscopy at Week 8 of Part 1 and Week 8 of Part 2. [ Time Frame: 8 Weeks ]
    Participants will receive 8 weeks of VE202/placebo in Part 1 and 2 weeks of VE202/placebo in Part 2. Endoscopic response is defined as a Mayo endoscopic subscore of 0 or 1 point. The Mayo endoscopic subscore is evaluated on a scale of 0 to 3, with a higher score representing more severe disease.

  6. Change in Mayo score compared with baseline at Week 8 of Part 1 and Week 8 of Part 2. [ Time Frame: 8 Weeks ]
    Participants will receive 8 weeks of VE202/placebo in Part 1 and 2 weeks of VE202/placebo in Part 2. The Mayo score is calculated as the sum of 4 subscores (stool frequency, rectal bleeding, endoscopy findings, and physician global assessment), with each parameter evaluated on a scale of 0 to 3. The total score ranges from 0 to 12, and a higher score represents more severe disease.

  7. Histologic improvement at Week 8 of Part 1 and Week 8 of Part 2 as measured by Geboes score. [ Time Frame: 8 Weeks ]
    Participants will receive 8 weeks of VE202/placebo in Part 1 and 2 weeks of VE202/placebo in Part 2. The Geboes score encompasses 6 dimensions, each with 4 subcategories: architectural changes, chronic inflammatory infiltrate, lamina propria neutrophils and eosinophils, neutrophils in the epithelium, crypt destruction, and erosions or ulcerations. The Geboes score ranges from grade 0 to 5.4. A higher Geboes score represents more severe disease.

  8. Histologic improvement at Week 8 of Part 1 and Week 8 of Part 2 as measured by the Robarts Histopathology Index (RHI). [ Time Frame: 8 Weeks ]
    Participants will receive 8 weeks of VE202/placebo in Part 1 and 2 weeks of VE202/placebo in Part 2. The RHI provides a score between 0 and 33, based on the levels of chronic inflammatory infiltrate, neutrophils in lamina propria and epithelium, and erosion/ulceration. A higher RHI score represents more severe disease.

  9. Change in fecal calprotectin levels after 2- and 8-week courses of VE202. [ Time Frame: 52 Weeks ]
    The change in fecal calprotectin level from baseline will be evaluated.

  10. Change in colonization with VE202 strains detected in feces at various time points in patients treated with 2- and 8-week courses of VE202. [ Time Frame: 52 Weeks ]
    VE202 colonization will be characterized in patients treated with 2- and 8-week courses of VE202.

  11. Change in the total percent of relative abundance of VE202 strains in feces at various time points in patients treated with 2- and 8-week courses of VE202. [ Time Frame: 52 Weeks ]
    VE202 colonization will be characterized in patients treated with 2- and 8-week courses of VE202.

  12. Change in taxonomic composition of gut microbiome in patients treated with 2- and 8-week courses of VE202. [ Time Frame: 52 Weeks ]
    Microbiome composition will be evaluated by measuring the sum of species and the genera or higher-level taxonomic groupings at baseline and at subsequent time points in patients treated with 2- and 8-week courses of VE202 or placebo.

  13. Change in fecal metabolite profiles at baseline and post-VE202 or placebo at various time points. [ Time Frame: 52 Weeks ]
    Short-chain fatty acid and bile acid concentrations will be evaluated at baseline and at subsequent time points in patients treated with 2- and 8-week courses of VE202 or placebo.

  14. Number of participants with hospitalization or surgical procedure related to UC after 2- and 8-week courses of VE202. [ Time Frame: 52 weeks ]
    To evaluate the impact of 2- and 8-week courses of VE202 on Inflammatory bowel disease (IBD) specific healthcare resource utilization.

  15. Change in patient-reported outcome measures using the Inflammatory Bowel Disease Questionnaire (IBDQ) to evaluate the impact of 2- and 8-week courses of VE202 IBD-specific health-related quality of life. [ Time Frame: 52 Weeks ]
    The 32-item IBDQ uses a 7-point scale to assess disease-specific health-related quality of life across 4 dimensions: bowel symptoms, systemic symptoms, emotional wellbeing, and social function. The total IBDQ score is calculated by adding the scores within each domain. Scores can range from 32 to 224, with a higher score indicating a better outcome.

  16. Change in patient-reported outcome measures using the EuroQoL-5D Health Assessment Questionnaire (EQ-5D) scores to evaluate the impact of 2- and 8-week courses of VE202 IBD-specific health-related quality of life. [ Time Frame: 52 Weeks ]
    The EuroQoL-5D Health Assessment Questionnaire (EQ-5D) is a standardized, self-administered, non-disease-specific instrument for measuring generic health status for routine clinical outcome measurement in the delivery of operational healthcare. Scores range from 0 to 100, with a higher score indicating better outcome.
