Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are healthy adults aged with BMI 18.0–32.0 kg/m2 and weight 50–100 kg, with no significant medical history.
✕Probably not a fit
Participants with inflammatory bowel disease, pregnancy, recent infections, or history of cancer (except certain non-melanoma skin cancers) may not benefit.

What this trial studies
This first-in-human study explores the tolerability and how the antibodies guselkumab and adalimumab behave when delivered via the colon. It uses single-dose administration to assess safety, tolerability, and pharmacokinetics, without planned interim analyses. The trial is designed for healthy subjects to see if colonic delivery can achieve systemic exposure. No results are available yet as the study is in early phases.
Why it matters
Potential benefit: If successful, this approach could open a new route for antibody delivery and inform future work in systemic exposure from the colon.
How similar studies have gone: Previous similar approaches are exploratory; this trial seeks to establish safety and pharmacokinetics for colonic delivery, which is relatively novel.
