Summary

This phase 2 study is testing two new drugs — mirikizumab (given by IV or injection) and LY4395089 (a pill) — in 60 adults with moderately to severely active ulcerative colitis or Crohn's disease. The goal is to see if these treatments are safe and can help control the disease. The study lasts at least 62 weeks and is currently recruiting participants.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Mirikizumab (given by IV or injection) and LY4395089 (taken by mouth)
What this could lead to
If successful, this could point toward new treatment options that help control symptoms and reduce disease activity for people with ulcerative colitis or Crohn's disease.
What could go wrong
This is an early phase 2 trial with only 60 participants, so results may not apply to everyone. The drugs may not work better than existing treatments or could have side effects.

This is an AI summary of the original study and may miss details. Read our disclaimer.
