Conducted By: University of Colorado and the Agency for

Healthcare Research and Quality
Lead Researcher: Dr. Amy Feldman
Study ID: COMIRB #20-0527
Last Updated: Version 2.3.2023

Why This Study Matters:

  • Only about 1 in 5 kids are fully vaccinated when they get a transplant.

  • 1 in 6 kids who have had a transplant ends up in the hospital later due to infections that could have been prevented by vaccines.

  • Phone apps can help remind you when it's time for the next vaccine.

Inclusion Criteria:

Your child is awaiting heart, liver, or kidney transplant



Duration of the study: 

You would participate from enrollment through your child’s transplant

Primary Investigator:  Amy Feldman, MD MSCS

Version 2.3.2023

Research Purpose: 

The goal of this research is to trial a mobile health tool (a phone app) to help increase immunization rates in the pre-transplant period

What Will You Need to Do?

  • Take a short online survey about your views on vaccines before the transplant.

  • Download our app, "Immunize PediatricTransplant," and use it as you find helpful.

  • After the transplant, fill out another short survey about your experience using the app.

​What is LIVMARLI (Maralixibat)?

LIVMARLI is a medication being tested for kids with biliary atresia. It works by targeting a specific part of your body called the ileal bile acid transporter (IBAT). By doing so, it helps reduce harmful bile acids in the liver and blood. These acids are then safely removed from the body through waste.

Why is This Study Important?
This research aims to find out how effective and safe LIVMARLI is for children with biliary atresia.

Your participation could help us better understand treatment options for this condition.

What is Odevixibat?

Odevixibat is a medication specifically designed for babies with biliary atresia who have had a Kasai procedure. It works by targeting a part of the body that helps control bile acids. The medication is easy to administer—it's a once-daily oral dose that can be mixed into breast milk, formula, or certain soft foods.

Why is This Study Important?
This is the first Phase 3 study to look at how safe and effective Odevixibat is for babies with biliary atresia. Your participation could help us better understand how to treat this condition more effectively.
