Hypersensitivity pneumonitis
MONDO:0017853Hypersensitivity pneumonitis (HP) is a pulmonary disease with symptoms of dyspnea and cough resulting from the inhalation of an antigen to which the subject has been previously sensitized.
Also known as: HP, allergic form of pneumonitis, allergic pneumonitis, exogen allergic alveolitis, extrinsic allergic alveolitis, hypersensitivity pneumonitis, allergic interstitial pneumonitis, alveolitis, extrinsic allergic

New inhaled therapy aims to slow lung scarring in progressive fibrosis
Disease control OngoingThis study tests an inhaled form of pirfenidone (AP01) in 375 adults with progressive pulmonary fibrosis (PPF), a condition where lung scarring worsens over time. Participants receive either a high dose, low dose, or placebo twice daily for 52 weeks, alongside their usual care. T…

New combo therapy aims to slow lung scarring in hypersensitivity pneumonitis
Disease control OngoingThis phase 4 trial tests whether adding mycophenolate mofetil (MMF) to standard prednisolone treatment works better than prednisolone alone for fibrotic hypersensitivity pneumonitis, a lung condition where scarring makes breathing hard. About 144 adults with at least 40% predicte…

Can a radioactive tracer reveal hidden lung scarring?
Knowledge-focused OngoingThis study tests whether a radioactive tracer called 68Ga-FAPi-46 can light up areas of scarring (fibrosis) in the lungs of people with interstitial lung disease. Participants receive the tracer and undergo a PET/CT scan to see where it collects. The goal is to understand how the…

Breathing in xenon: a new MRI scan to see lung damage?
Knowledge-focused OngoingThis study at Duke University tests whether a special MRI scan using inhaled xenon gas can detect changes in lung function over time in people with progressive pulmonary fibrosis. Sixty adults with various types of lung scarring will have MRI scans before starting anti-fibrotic m…

Lung disease study probes hidden environmental triggers
Knowledge-focused OngoingThis study looks at how things in the environment and at work might affect people with interstitial lung diseases (a group of lung conditions). Researchers will ask 1,000 adults with a new diagnosis about their exposures to things like pollution, chemicals, and dust. The goal is …

Blood test may predict lung decline in rare disease
Knowledge-focused OngoingThis study is looking for markers in the blood that can predict whether a person's chronic hypersensitivity pneumonitis will get worse over time. Researchers will follow about 137 patients at 7 U.S. centers for 24 months, tracking lung function, symptoms, and CT scans. The goal i…
