The number of approved treatments for Crohn's disease has grown over the years, thanks to clinical research and those who have participated. But there is still a need to find treatments that work for those impacted the most. The DUET-CD Study is one of the few clinical trials, so far, that is evaluating combinations of investigational biologics that may one day be an option for those with Crohn's disease.

You may be able to take part in the DUET-CD Study if you:

  • Are 18 to 65 years old
  • Have had a diagnosis of Crohn's disease or fistulizing Crohn's disease for at least 3 months
  • Are currently experiencing a reappearance or worsening of your Crohn's disease symptoms, called a flare, which may include:
    • Frequent and/or urgent bowel movements
    • Abdominal pain
    • Lack of appetite
    • Diarrhea
  • Have been unsuccessful with previous medications to treat your Crohn's disease

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