Can antibodies enter the bloodstream via the colon?
NCT ID NCT07788807
First seen Aug 26, 2026 · Last updated Aug 27, 2026 · Updated 1 time
Summary
This early-stage trial explores whether two antibodies, adalimumab and guselkumab, can be absorbed into the bloodstream when delivered directly to the colon. Healthy adult volunteers will receive a single dose of each antibody via the colon, and researchers will measure how much reaches the blood and how the body handles it. The study also monitors safety and tolerability, aiming to understand if this novel route could be a viable way to administer these medications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- adalimumab and guselkumab administered directly into the colon
- What this could lead to
- If successful, this could pave the way for delivering antibody treatments via the colon, potentially offering a less invasive alternative to injections for chronic conditions.
- What could go wrong
- This is an early-phase study with only 18 healthy participants, so results may not apply to patients. The antibodies might not absorb well or could cause side effects.
