Savara Presented New Data on Autoimmune Pulmonary Alveolar Proteinosis (aPAP) at the American Thoracic Society (ATS) International Conference 2024

Savara’s Partner, Trillium Health LLC, Presented Data on the Laboratory Blood Test for Diagnosing aPAP

LANGHORNE, Pa.--(BUSINESS WIRE)--May 19, 2024-- Savara Inc. (Nasdaq: SVRA) (the Company), a clinical stage biopharmaceutical company focused on rare respiratory diseases, presented a poster at the American Thoracic Society (ATS) 2024 International Conference that is taking place May 17-22, 2024, in San Diego, CA. Savara’s partner, Trillium Health LLC, presented a poster on the laboratory blood test that was recently developed to aid in the diagnosis of aPAP.

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 ( 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.

About aPAP

Autoimmune PAP is a rare lung disease characterized by the abnormal build-up of surfactant sediment in the alveoli (or air sacs) of the lungs. The surfactant consists of proteins and lipids and is an important physiological substance that lines the inside of the alveoli to prevent the lungs from collapsing. In a healthy lung, the old and inactivated surfactant is cleared and digested by immune cells called alveolar macrophages. Alveolar macrophages need to be stimulated by granulocyte-macrophage colony-stimulating factor (GM-CSF) to function properly in clearing surfactant, but in autoimmune PAP, GM-CSF is neutralized by antibodies against GM-CSF, rendering the macrophages unable to perform their tasks. As a result, an excess of surfactant accumulates in the alveoli, causing obstruction of gas exchange, and patients start to experience shortness of breath, often with cough and frequent fatigue. Patients may also experience chronic cough, as well as episodes of fever, chest pain, or coughing blood, especially if secondary lung infection develops. In the long-term, the disease can lead to serious complications, including lung fibrosis and the need for a lung transplant.
