We Know IBD - Astro

The ASTRO Study is evaluating the safety and efficacy of an investigational medication compared with placebo in adults with moderately to severely active ulcerative colitis (UC).

See If You Are Eligible


There have been a growing number of approved treatments for UC over the years, thanks to clinical research and those who have participated. Although some of the approved treatments for UC are delivered intravenously, or through a vein, the ASTRO Study will explore whether an investigational medication delivered in a less-invasive way-subcutaneously, or under the skin-is safe and effective.

You may be able to take part in the ASTRO Study if you:

  • Are at least 18 years old
  • Have had a diagnosis of ulcerative colitis for at least 3 months
  • Are currently experiencing a reappearance or worsening of your ulcerative colitis symptoms, called a flare, which may include:
    • Frequent and/or urgent bowel movements
    • Abdominal pain
    • Lack of appetite
    • Diarrhea
    • Rectal bleeding
  • Have been unsuccessful with previous medications to treat your ulcerative colitis

Additional eligibility criteria will be assessed by the trial doctor or staff.
