Below are summaries of the posters presented:
Poster Board 701: "Healthcare Burden of Pulmonary Alveolar Proteinosis" presented by E. Lee, M.D., Ph.D.; sponsored by Savara Inc.
- Presented data from a retrospective cohort analysis using a longitudinal claims database (IPM.ai) comparing the clinical and economic burden of a sample of 2,312 pulmonary alveolar proteinosis (PAP) patients to 9,247 non-PAP matched controls.
- Data demonstrated PAP patients experience higher healthcare resource utilization and higher pharmaceutical and non-pharmaceutical costs as evidenced by a 4-fold increase in hospital admissions, 6-fold increase in in-patient visits, and a 4-fold increase in cost of care, as well as higher rates of comorbidities, procedures, and therapy use (all parameters p<0.001), thereby highlighting a significant unmet need in this rare disease patient population.

Poster Board 702: "Development of a Novel Laboratory Test for the Detection of GM-CSF Antibodies to Aid in the Diagnosis of Individuals At-risk for Autoimmune Pulmonary Alveolar Proteinosis (aPAP)" presented by A. Ali and J. Kim of Trillium Health LLC
- Presented data on the development and performance characteristics of a novel laboratory test for the detection of granulocyte-macrophage colony-stimulating factor (GM-CSF) antibodies in human serum to aid in the diagnosis of aPAP.
- Clinical accuracy of 100% was achieved in a cohort of 40 subjects (negative cohort n=20, positive cohort n=20), demonstrating Trillium's particle-based flow cytometry immunoassay test offers a highly precise and sensitive laboratory test for the determination of GM-CSF antibody levels in human serum and, thus, can successfully be used as a tool to definitively diagnose aPAP.
