Functional Studies of Novel Genes Mutated in Primary Ciliary Dyskinesia II: Genotype to Phenotype

University of North Carolina, Chapel Hill·interventional·Posted May 25, 2021·Updated Sep 5, 2025

In Brief

A Early Phase 1 clinical trial evaluating Albuterol and Technetium99m - Sulfur Colloid (Tc99m-SC) for Primary Ciliary Dyskinesia. Completed, enrolled 27 participants across 1 site.

Detailed Summary

The purpose of this study is to measure mucociliary clearance (MCC) in groups of subjects with the disease Primary Ciliary Dyskinesia (PCD) caused by mutations in different genes, and compare to healthy subjects. Some of these genes are associated with a milder clinical phenotype. This study seeks to determine if the milder phenotype is a result of mutations in a set of specific genes. The hypothesis is that subjects with PCD caused by mutations in the milder group will maintain a low, but significant rate of mucociliary clearance, while patients with mutations in genes in the more severe group will have a complete absence of mucociliary clearance. These studies will help inform future treatment strategies.

Interventions

Albuteroldrug

Albuterol HFA Metered Dose Inhaler (90mcg/puff). Subjects to use 4 puffs one time.

Technetium99m - Sulfur Colloid (Tc99m-SC)other

Aerosolized radiolabeled Tc99m-sulfur colloid will be delivered using a modified Pari-LC Star nebulizer. The activity of Tc99m-SC loaded in the nebulizer will be adjusted to provide an estimated 40 microcurie (µCi) deposited in the lung for the MCC/CC scan. Patients between the age 12-18 years old will receive three quarters of the adult dose to account for the smaller lung volume.
