Study Summary

This trial is researching a new cell transplantation therapy for genetic diseases & studying new treatments that may help other diseases.

Who is the study for?
Adults diagnosed with hereditary Pulmonary Alveolar Proteinosis (hPAP) who have either received Whole Lung Lavage therapy or have moderate disease severity needing treatment. Participants must be able to undergo bone marrow collection, use effective contraception if of childbearing potential, and provide written consent.Check my eligibility
What is being tested?
The trial is testing a new cell transplantation therapy where gene-corrected macrophages are delivered directly into the lungs via bronchoscopy. The aim is to assess safety and effectiveness for hPAP and understand lung macrophage functions.See study design
What are the potential side effects?
Potential side effects may include reactions related to bronchoscopic procedures such as coughing or wheezing, discomfort at the bone marrow collection site, and immune responses against the introduced cells or vector.

Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Number of patients with adverse events (AEs)
Secondary outcome measures
Biodistribution of transplanted macrophages via detection of lentiviral DNA in BAL and blood
Concentration of PAP biomarkers in bronchoalveolar lavage fluid
Difference in Health Status/Quality of Life Score via the 36-Item Short Form Survey (SF-36) Questionnaire
+22 more
Other outcome measures
Cell population dynamics of transplanted macrophages via RNA sequencing t-distributed stochastic neighborhood embedding analysis (t-SNE)
Percentage of bronchoalveolar lavage cells that respond to GM-CSF stimulation
Transcriptional regulation of alveolar macrophage specification via an assay for transposable-accessible chromatin with sequencing
