Bronchiectasis Understanding and Treatment Algorithm

Bronchiectasis overview

Bronchiectasis is a chronic, progressive lung disease characterized by irreversible bronchial airway dilation and impaired mucociliary function, resulting in persistent mucus buildup and heightened bacterial colonization. Although historically linked to childhood respiratory infections, the disease is now understood to have multifactorial origins, including idiopathic, acquired, or infection-related causes. A productive cough is the hallmark symptom, yet in nearly 40% of cases, the cause remains unidentified. Bronchiectasis frequently develops secondary to pulmonary conditions such as cystic fibrosis, COPD, autoimmune diseases, immunodeficiencies, and airway obstructions, or through recurrent infections, including pneumonia and tuberculosis. The disease presents with gradually worsening airflow obstruction, marked by chronic cough, thick mucus production, shortness of breath, and systemic signs like fever, fatigue, and chest pain. As the condition advances, complications such as hemoptysis and nail clubbing may arise, underscoring the impact of recurrent infections, airway blockages, and peribronchial fibrosis on disease progression.

Bronchiectasis diagnosis

The diagnosis of bronchiectasis is primarily established through chest computed tomography scans, which provide detailed imaging of bronchial dilation and associated abnormalities. Complementary diagnostic modalities, including chest X-rays, bronchoscopy, lung function tests, blood tests, and sputum cultures, are utilized to identify potential underlying conditions and assess microbial colonization. The definitive diagnostic tool for bronchiectasis is High-Resolution Computed Tomography (HRCT) of the chest, optimally conducted when the patient is clinically stable to ensure accuracy. HRCT provides detailed imaging of the bronchial structure, with tubular bronchiectasis emerging as the most frequently observed subtype. This imaging modality allows for precise identification of bronchial dilation and related abnormalities, facilitating early intervention and improved disease management.

Bronchiectasis treatment

The management of Bronchiectasis centers on identifying and addressing underlying causes, such as prior severe respiratory infections, allergic bronchopulmonary aspergillosis, ciliary clearance impairment, immunodeficiency, COPD, and severe asthma. Treatment strategies focus primarily on symptomatic relief and optimizing lung function through mucus clearance techniques, infection control with antibiotics, and the use of bronchodilators or corticosteroids to alleviate airflow obstruction. Supportive measures, including smoking cessation and vaccinations, play a key role, while advanced cases may require surgical intervention or lung transplantation. However, the absence of disease-modifying therapies highlights a critical gap in treatment, as current approaches primarily manage symptoms without addressing the root causes of Bronchiectasis. Although inhaled corticosteroids and long-term macrolide therapies show promise, efficacy evidence remains limited by small cohorts and brief trial durations, underscoring the urgent need for more robust research to develop targeted therapies capable of reversing structural damage and improving long-term patient outcomes.

Bronchiectasis Drug Chapters

Emerging Drugs

Brensocatib: Insmed/AstraZeneca

Brensocatib, an oral small-molecule inhibitor targeting dipeptidyl peptidase 1 (DPP1), is being developed by Insmed for the treatment of bronchiectasis, CRSsNP, and other neutrophil-driven conditions. By inhibiting DPP1, brensocatib aims to reduce inflammation by blocking the activation of neutrophil serine proteases (NSPs), such as neutrophil elastase, during neutrophil formation in the bone marrow. Insmed reported positive topline results from the Phase III ASPEN study of brensocatib in patients with bronchiectasis, leading to plans for a New Drug Application (NDA) submission to the US FDA in late 2024. If approved, brensocatib is expected to launch in the US by mid-2025, followed by launches in Europe and Japan in the first half of 2026. In October 2024, Insmed shared positive late-breaking subgroup data from the Phase III ASPEN study of brensocatib for patients with bronchiectasis at the CHEST 2024 Annual Meeting. Furthermore, the EMA approved a Pediatric Investigational Plan for brensocatib in bronchiectasis patients, and brensocatib has gained access to the PRIME scheme and Breakthrough Therapy Designation for adult bronchiectasis patients.

Physician’s View

As per the KOLs from the US, Exacerbations are critical events in the course of bronchiectasis, often triggered by bacterial or viral infections. Beyond worsening symptoms, they can significantly reduce quality of life, impair lung function, and increase the risk of hospitalization and mortality. Understanding the impact of these episodes is essential to improving prevention strategies and developing more effective interventions for patients.

As per the KOLs from the UK, previous severe respiratory infections, allergic bronchopulmonary aspergillosis, impaired ciliary clearance, primary or secondary immunodeficiency, and other illnesses linked with bronchiectasis, such as COPD and severe asthma, are only a few of the predisposing factors that may be found. Despite following the suggestions in the guidelines, 40% of patients cannot determine the cause of their bronchiectasis, and only 13% of those cases result in a change in how the patients are managed.

As per the KOLs from Japan, surgery is most effective for symptomatic bronchiectasis, caused by a localized structural alteration in the airway in otherwise healthy people. The most common causes of airway damage include childhood infections such as TB, measles, pertussis, and post-infectious bronchiectasis.
