Pulmonary alveolar proteinosis Understanding

Pulmonary alveolar proteinosis: Overview

Pulmonary alveolar proteinosis (PAP) is a rare pulmonary disease characterized by alveolar accumulation of surfactant-derived lipoproteinaceous material. This accumulation blocks air from entering alveoli and oxygen from passing through into the blood, which results in a feeling of breathlessness (dyspnea). Depending on the aetiology three main categories of PAP have been defined: auto-immune (previously named primary or idiopathic), secondary and genetic. Genetic PAP is seen especially in children, and radio-clinical presentation depends on the mutated gene. Auto-immune alveolar proteinosis is the most frequent form of PAP, representing 90% of cases. Patients with PAP are at an increased risk of developing an opportunistic infection.

Symptoms

The symptoms of Pulmonary alveolar proteinosis include:

• Cyanosis
• Chest pain or tightness
• Shortness of breath, also called dyspnea
• Fever
• Weight loss
• Cough (sometimes, but not always)
• Low levels of oxygen in the blood
• Nail clubbing (abnormal growth of toenails or fingernails)
• Fatigue

Diagnosis

Diagnosis of PAP is initiated by computed tomography (CT) scan and confirmed by staining of bronchoalveolar lavage fluid (BALF). PAP diagnosis rarely requires lung biopsy. Autoimmune PAP can be identified by very sensitive and specific blood tests that identify the presence or absence of an increased level of GM-CSF autoantibody. Hereditary PAP can be diagnosed by a series of blood tests. The genetic risk factors for hereditary PAP and congenital PAP can be identified by genetic testing.

Treatment

The standard treatment for PAP is symptomatic whole lung lavage. Therapy for PAP varies depending upon what disease is present, disease severity, and the age of the patient. Treatment of congenital PAP is generally supportive. Lung transplantation can be used in infants and children with congenital PAP caused by genetic mutations and in patients who develop significant lung fibrosis. Some novel therapies targeting alveolar macrophages (recombinant GM-CSF therapy) or anti-GM-CSF antibodies (rituximab and plasmapheresis) are under investigation.

Pulmonary alveolar proteinosis Emerging Drugs Chapters

This segment of the Pulmonary alveolar proteinosis report encloses its detailed analysis of various drugs in different stages of clinical development, including phase II, I, preclinical and Discovery. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Pulmonary alveolar proteinosis Emerging Drugs

• Molgradex: Savara

Molgradex is an investigational inhaled formulation of recombinant human GM-CSF. It is being evaluated for the treatment of autoimmune pulmonary alveolar proteinosis (aPAP). It has been granted Orphan Drug Designation for the treatment of aPAP in the U.S. and the European Union. A pivotal Phase 3 clinical study, called IMPALA, of Molgradex for the treatment of aPAP was completed in 2019.

• Sargramostim: Bayer HealthCare Pharmaceuticals

Sargramostim is a yeast-derived recombinant human granulocyte-macrophage colony stimulating factor (rhu-GM-CSF). The therapy stimulates the production of white blood cells including neutrophils, monocytes/macrophages and myeloid-derived dendritic cell and promote their ability to function. The U.S. Food and Drug Administration (FDA) has granted orphan drug designation to sargramostim), for the treatment of pulmonary alveolar proteinosis (PAP).
