Design outcomes
Primary
| Measure | Time frame |
|---|---|
| - To evaluate the feasibility of a multicenter trial on different continents with treatment allocation at week 4 depending on stool sample results at baseline - To evaluate the potential efficacy of personalized adjunctive antibiotic therapy in maintaining clinical remission in pediatric subjects undergoing SOC induction therapy for mild to moderate Crohn’s disease who have a relapse-associated microbiome profile | — |
Secondary
| Measure | Time frame |
|---|---|
| - To evaluate the potential efficacy of personalized adjunctive antibiotic therapy in improving PRO, components of established disease activity measures in remission, as well as ‘biochemical’ remission in pediatric subjects undergoing SOC induction therapy for mild to moderate Crohn’s disease who have a relapse-associated microbiome profile - To investigate relationship between changes in subject microbiome composition and changes in disease activity over time. | — |
