Study for Adults 18 to 25 Years Old With Crohn’s Disease

Why are we doing this research?

Cincinnati Children’s is conducting a research study, sometimes known as a clinical trial or clinical study, to learn more about how well vitamin D is absorbed and transformed to its active form in adults who are healthy compared with adults who have Crohn’s Disease.

Who can participate?

Adults 18 to 25 years old who have been diagnosed with Crohn’s Disease and are taking either Infliximab (Remicade) or Adalimumab (Humira) may be eligible to participate.

Conditions

  • Crohns Disease and Colitis
  • Gastroenterology - Digestive Tract - Stomach - Liver
  • Adult Studies

What will happen in the study?

This study involves 3 study visits in a week. Here are some of the things that will happen in this study:

You will come in at 8 am for a full-day visit (8 hours), after fasting from the night before.

You will:

  • Have an IV placed in your arm to collect blood
  • Receive vitamin D in capsule form
  • Be able to eat a provided breakfast 30 minutes after taking the vitamin D
  • Have two additional blood draws during this visit from the same IV. You may opt to not have an IV in place.

You will come in for a blood draw 24 hours after completing the first visit, and then 7 days later. These two additional visits will be brief. The only restrictions are to not take any vitamin D supplements or use a tanning bed during this 7-day period.

You will be given a consent form that thoroughly explains all of the details of the study. A member of the study staff will review the consent form with you and will be sure that all of your questions are answered.

What are the good things that can happen from this research?

You will not receive a medical benefit from being in this study, but the information we learn about how vitamin D works in IBD patients may help them in the future.

What are the bad things that can happen from this research?

We will discuss possible risks and discomforts with those interested in knowing more about this study.

Will you/your child be paid to be in this research study?

Participants may receive up to $200 for time and effort. You will be provided a small breakfast and a meal ticket for lunch on the day of the first visit.
