Chronic Pulmonary Infections Clinical Trials Analysis 2025: Inhaled Antimicrobials, NTM-Targeted Regimens, and Host-Directed Strategies Aim to Suppress Pathogens and Preserve Lung Function | DelveInsight

DelveInsight's "Chronic Pulmonary Infections - Clinical Trials Analysis, 2025" outlines an active and heterogeneous development landscape addressing long-standing airway infections (non-CF bronchiectasis, chronic Pseudomonas infection, and pulmonary nontuberculous mycobacteria [NTM]). Trials prioritize durable microbiological suppression, exacerbation reduction, and functional outcomes (lung function, exacerbation rate, quality of life) because persistent infection drives progressive decline and healthcare use.

Late-stage and registration-enabling programs focus on inhaled and targeted antimicrobials (liposomal amikacin/ALIS and novel inhaled formulations, including clofazimine inhalation), repeatable regimens for refractory non-tuberculous mycobacteria (NTM, such as MAC and M. abscessus), and optimized inhaled antibiotics for chronic Pseudomonas infections in bronchiectasis. These approaches aim to deliver high airway drug concentrations while limiting systemic toxicity.

Complementary strategies include host-directed and anti-inflammatory approaches (for example, neutrophil-targeting agents such as brensocatib) to reduce exacerbations and airway damage, plus growing interest in bacteriophage therapies, adjunctive immunomodulators, and microbiome-aware treatments that may improve long-term control when combined with antimicrobials. Trial designs increasingly measure exacerbation frequency, sputum pathogen load, patient-reported respiratory symptoms, and functional endpoints.

The pipeline spans industry and academic sponsors with trials across refractory NTM, frequent-exacerbation bronchiectasis, and chronic Gram-negative infections. Biomarker and microbiological endpoints (culture conversion, pathogen load) are used alongside clinical outcomes to demonstrate both pathogen clearance and meaningful patient benefit. Upcoming pivotal readouts for inhaled antimicrobials, NTM regimen trials, and anti-neutrophil agents over the next 12-24 months will be crucial in shifting care from symptomatic control to durable infection suppression and preservation of lung function.

• The leading chronic pulmonary infections companies include Chiesi Farmaceutici, Armata Pharmaceuticals, Genentech, Altesa Biosciences, Kinaset Therapeutics, Apogee Therapeutics, and others are evaluating their lead assets to improve the chronic pulmonary infections treatment landscape.
• Key chronic pulmonary infections pipeline therapies in various stages of development include Tanimilast, AP-PA02, Astegolimab, Vapendavir, KN-002, APG808, and others.
• In March 2025, Japan's Ministry of Health, Labour and Welfare granted marketing and manufacturing authorization for DUPIXENT (dupilumab) to treat chronic obstructive pulmonary disease (COPD) in adults with inadequate control using existing therapies.
• In February 2025, Insmed Incorporated announced that the FDA informed the company it does not plan to hold an advisory committee meeting to discuss the New Drug Application (NDA) for brensocatib for patients with non-cystic fibrosis bronchiectasis.
• In December 2024, Inogen received FDA 510(k) clearance for its SIMEOX 200 Airway Clearance Device, expanding its respiratory product portfolio in the U.S. The upgraded version of the original Simeox uses high-frequency oscillatory vibrations and intermittent negative pressure during exhalation to improve bronchial drainage in patients with chronic lung diseases like Bronchiectasis, COPD, Cystic Fibrosis, and Primary Ciliary Dyskinesia.
• In September 2024, Regeneron Pharmaceuticals, Inc. and Sanofi announced FDA approval of DUPIXENT (dupilumab) as an add-on maintenance treatment for adults with inadequately controlled chronic obstructive pulmonary disease (COPD) with an eosinophilic phenotype. Dupixent is the first biologic approved in the U.S. for
• In September 2024, GSK plc announced positive results from the Phase III MATINEE trial of Nucala (mepolizumab) in adults with chronic obstructive pulmonary disease (COPD). The trial demonstrated that adding Nucala to optimized inhaled maintenance therapy significantly reduced the annualized rate of moderate/severe exacerbations compared to placebo in COPD patients with type 2 inflammation.

Chronic Pulmonary Infections Overview
Chronic pulmonary infections are long-lasting lung infections that progress slowly and often resist treatment, requiring prolonged care. They are commonly caused by bacteria (e.g., Mycobacterium tuberculosis, Pseudomonas aeruginosa), fungi (Aspergillus), and sometimes viruses, especially in people with conditions like COPD, cystic fibrosis, or weakened immunity. Symptoms include persistent cough, blood-tinged sputum, fatigue, breathlessness, chest pain, fever, night sweats, and weight loss. If left untreated, these infections can lead to complications like bronchiectasis or lung abscesses.

Diagnosis involves clinical evaluation, imaging (X-ray or CT), and lab tests such as sputum cultures, bronchoscopy, or PCR. Treatments are pathogen-specific and often lengthy. TB, for instance, requires multi-drug regimens over several months. NTM and Pseudomonas infections may need inhaled or IV antibiotics, while fungal infections are managed with antifungals. In severe or unresponsive cases, surgery may be needed. Effective management also includes treating underlying diseases and maintaining good pulmonary hygiene.

Chronic Pulmonary Infections Treatment Analysis: Drug Profile
Tanimilast (CHF6001): Chiesi Farmaceutici
Tanimilast is an innovative inhaled phosphodiesterase 4 (PDE4) inhibitor developed by Chiesi Farmaceutici for the treatment of chronic inflammatory lung diseases such as COPD and asthma. By targeting airway inflammation, it helps manage exacerbations commonly seen in chronic pulmonary conditions. Clinical studies have demonstrated its potential in improving lung function and reducing flare-ups in patients with COPD, making it a promising candidate for treating chronic pulmonary infections associated with underlying inflammation. The drug is currently in Phase III development for this indication.

AP-PA02: Armata Pharmaceuticals
AP-PA02 is a cutting-edge phage therapy developed by Armata Pharmaceuticals, specifically designed to combat Pseudomonas aeruginosa-driven respiratory infections. This formulation comprises a potent cocktail of natural bacteriophages, each selected for its broad host range and ability to target different receptor classes on P. aeruginosa. Engineered for synergistic action, AP-PA02 is delivered via inhalation in a sterile liquid form and manufactured under cGMP conditions at Armata's California facility. It is currently in Phase II clinical trials for the treatment of chronic pulmonary infections.
