Non-Cystic Fibrosis Bronchiectasis Understanding and Treatment Algorithm

Non-Cystic Fibrosis Bronchiectasis overview

NCFB is a chronic inflammatory lung condition characterized by irreversible bronchial dilation, resulting in persistent sputum production and compromised bacterial clearance. This dysfunction establishes a detrimental cycle where ineffective pathogen elimination leads to recurrent infections, chronic inflammation, and progressive pulmonary damage. Symptoms commonly include cough, excessive sputum production, and frequent respiratory infections, alongside additional manifestations such as shortness of breath, wheezing, hemoptysis, and chest pain. The severity of these symptoms can vary considerably among individuals, with some experiencing mild, sporadic episodes while others endure daily, debilitating symptoms, often exacerbated by infectious triggers. NCFB is frequently associated with comorbidities like anxiety, depression, and fatigue, which significantly diminish patients’ quality of life and contribute to longer hospital stays and increased outpatient visits. The etiology of NCFB is multifaceted, with a considerable proportion of cases attributed to idiopathic factors, post-infective complications, and associations with conditions such as COPD and asthma, underscoring the complexity of its management.

Non-Cystic Fibrosis Bronchiectasis diagnosis

The diagnosis of NCFB 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. Given the heterogeneous nature of bronchiectasis and its multifactorial origins, no single diagnostic measure can comprehensively evaluate disease severity or prognosis. To address this complexity, two validated scoring systems - the Bronchiectasis Severity Index (BSI) and the FACED score - are employed to systematically assess disease severity. These tools integrate clinical and radiological parameters, enabling a more nuanced understanding of the condition and informing individualized management strategies.

Non-Cystic Fibrosis Bronchiectasis treatment

The treatment of NCFB is focused on symptom management, slowing the decline in lung function, and preventing exacerbations. Chest physiotherapy is a cornerstone of management due to its effectiveness and minimal side effects, while some patients derive additional benefit from specialized interventions, including regular administration of low-dose macrolides as prophylactic antibiotics. The current treatment regimen encompasses a multifaceted approach, incorporating antibiotics, corticosteroids, bronchodilators, acid suppression medications, active mucolytic agents, and strategies to enhance bronchial hygiene. Elevated neutrophil levels in the airways underscore the potential efficacy of anti-inflammatory therapies, such as corticosteroids and macrolides, in mitigating inflammation. However, the heterogeneity of NCFB necessitates a personalized treatment approach, as existing therapies can be labor-intensive and may induce side effects, contributing to rising resistance to current medications. This complexity emphasizes the critical need for novel drug development to provide more effective and streamlined treatment options tailored to individual patient profiles.

Non-Cystic Fibrosis 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 NCFB, 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 NCFB at the CHEST 2024 Annual Meeting. Furthermore, the EMA approved a Pediatric Investigational Plan for brensocatib in NCFB patients, and brensocatib has gained access to the PRIME scheme and Breakthrough Therapy Designation for adult NCFB patients.

Inhaled Colistimethate Sodium (CMS I-neb): Zambon

CMS I-neb is an investigational inhaled therapy for adults with NCFB colonized by P. aeruginosa, potentially offering a first-in-class treatment option. It uses colistimethate sodium, a prodrug of colistin, a polymyxin antibiotic targeting aerobic Gram-negative pathogens, including drug-resistant P. aeruginosa. By disrupting the bacterial cell membrane, colistin causes cell death and serves as a last-resort treatment for infections like carbapenem-resistant P. aeruginosa. In September 2024, Zambon released the results of the Phase III PROMIS-I and PROMIS-II studies in The Lancet Respiratory Medicine journal. The Phase III PROMIS-I trial demonstrated a significant reduction in pulmonary exacerbation rates. Although the PROMIS-II trial was terminated early due to the pandemic, pre-pandemic data showed consistency with PROMIS-I outcomes. Zambon is working with regulatory authorities to expedite patient access. The US FDA has granted CMS I-neb Breakthrough Therapy Designation (BTD), as well as QIDP and Fast Track Designation (FTD).

FASENRA (benralizumab): AstraZeneca
