Hp129 Xenon Imaging and BOS in Lung Transplantation
Imaging and Understanding Bronchiolitis Obliterans Syndrome (BOS) in Lung Transplantation With Hyperpolarized 129Xenon MR Lung Imaging
Study Overview
Detailed Description
This protocol aims to
- Develop new imaging methods that are sufficiently sensitive to allow early diagnosis of BOS.
- Improve patient treatment outcomes through earlier diagnosis of changes leading to BOS by obtaining image guided biopsies of transplanted lung.
- Provide image guided biopsies for use in future research of ex vivo biomarkers of BOS and in the development of treatments through future clinical trials.
The study will achieve these aims through a prospective, non-randomized, longitudinal, observational study that will recruit about 5 subjects a year for 5 years. The study will follow these post lung transplant patients at 6 months and 1 year with 129Xe MRI (Hyperpolarized 129Xenon Magnetic Resonance Imaging) and image guided bronchial biopsies to detect early BOS and to better understand BO disease progression. The biopsies will provide future research for rapid determination of cellular and molecular mechanisms that lead to BOS and to facilitate identification and validation of translatable pharmaceutical targets.

- Masking: None (Open Label)
Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Hp 129Xenon
Participants will inhale up to 4 doses of Hp129Xenon; each dose will be no more than 1 liter.
|
129 Xenon is a noble gas with no taste or smell.
It will be made slightly magnetic (also called hyperpolarizing) and then inhaled into the lungs to provide better pictures of the lungs during MRI.
