Savara Presented Data at the European Respiratory Society (ERS) International Congress 2022
Below are summaries of each poster presented:
Abstract #2170: “IMPALA: Efficacy Measures in Patients with Autoimmune Pulmonary Alveolar Proteinosis (aPAP) Who Required Whole Lung Lavage” presented by
- Presented data from a post hoc analysis of the IMPALA clinical trial evaluating the benefit of continuous daily administration of inhaled molgramostim 300 μg vs placebo among patients with aPAP who required whole lung lavage (WLL) during the double-blind treatment period. A total of 10 patients underwent WLL in the treatment period (molgramostim: n=4, placebo: n=6)
- Data demonstrated that patients treated with molgramostim after undergoing WLL had greater improvements in endpoint measures of gas exchange, including alveolar-arterial oxygen difference (A-aDO2) and diffusing capacity of the lungs for carbon monoxide (DLco) corrected for hemoglobin levels. Additionally, patients reported improved health status, as measured by St. George’s Respiratory Questionnaire-Total and -Activity, when compared with placebo-treated patients .

Abstract #1154: “Safety and Tolerability of Inhaled Molgramostim in Autoimmune Pulmonary Alveolar Proteinosis (aPAP)” presented by
- Included safety data from an open-label, non-controlled extension study of IMPALA (IMPALA-X) in which 60 patients received treatment with inhaled molgramostim 300 μg/day administered intermittently (1 week on and 1 week off). This study was discontinued early as results from IMPALA did not support this dosing regimen.
- In IMPALA-X, no new safety signals were observed and the most common treatment-related adverse events after 93.4 patient-years of exposure were mild-to-moderate cough, nasopharyngitis, and respiratory tract infection.

Abstract #3136: “IMPALA-2: Choice of DLco as a Primary Endpoint in Autoimmune Pulmonary Alveolar Proteinosis (aPAP)” presented by
-
Described rationale for using DLco as a primary endpoint in the IMPALA-2 clinical trial, including:
- In the first IMPALA trial, DLco showed robust improvements in patients with aPAP who were treated with continuous daily molgramostim 300 μg compared to those treated with placebo
- DLco is a standardized, widely used lung function test with direct relevance to the pathophysiology of aPAP, and is predictive for the major clinical event of WLL
- IMPALA-2 is an ongoing pivotal Phase 3, randomized, double-blind, placebo-controlled global clinical trial evaluating once daily molgramostim 300 μg in patients with aPAP

About aPAP
Autoimmune pulmonary alveolar proteinosis (aPAP) is a rare lung disease that belongs to a family of distinct rare lung diseases collectively known as pulmonary alveolar proteinosis (PAP). aPAP represents about 90% of all patients with PAP. While aPAP can affect people of any age, race or sex, onset occurs most frequently in people between the ages of 30 and 40. PAP is characterized by the build-up of surfactant 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. The root cause of aPAP is an autoimmune response against GM-CSF, a naturally occurring protein in the body. Pulmonary macrophages need to be stimulated by GM-CSF to function properly, but in aPAP, GM-CSF is neutralized by antibodies against GM-CSF, rendering the macrophages unable to perform their tasks, including the clearance of surfactant from the alveoli. In aPAP, the feeling of having trouble breathing is the most common symptom. People with aPAP can also experience chronic cough, fatigue, sputum production, reduced ability to exercise and episodes of fever due to underlying pulmonary infections. There are currently no approved pharmaceutical treatment options for aPAP.
