This study looks at whether a breathing technique used by free divers can reduce symptoms of allergic rhinitis, like nasal congestion and sneezing. Thirty adults with persistent allergies will practice the 40-minute breathing sessions. Researchers will measure symptom scores, nas…

This study compares two nasal sprays for moderate-to-severe allergic rhinitis (hay fever): fluticasone alone versus a combination of fluticasone and azelastine. Researchers will track symptom relief and quality of life in 61 adults over two months to see which spray works better …

This study tests a new injection called LP-003 in 6 teenagers aged 12 to 18 who have allergies like hay fever, asthma, or eczema. The main goal is to check if the drug is safe and how the body processes it. This is an early-stage trial, so it focuses on safety and drug levels rat…

This study tests a procedure called RhinAer that uses heat to treat the nerves in the nose for people with chronic rhinitis (long-term stuffy or runny nose). Researchers want to see if it reduces inflammation and improves symptoms like cough and post-nasal drip. About 25 adults a…

This pilot study tests whether tezepelumab, a drug already approved for severe asthma, can also reduce nasal symptoms caused by hayfever in people who have both allergic asthma and allergic rhinitis. Nineteen participants will receive monthly injections of tezepelumab for 12 mont…

This study tests an experimental injection called LP-003 in 546 adults with moderate to severe seasonal allergic rhinitis (hay fever) that standard medications don't manage well. Participants receive either the drug or a placebo, and report their nasal symptoms daily. The goal is…

This study was designed to see if a combination of levocetirizine (an allergy medicine) and pseudoephedrine (a decongestant) works better than levocetirizine alone for relieving nasal congestion in people with allergic rhinitis. It planned to enroll people aged 12 to 65 with the …

This study tests a laser procedure that targets nerves in the nose to relieve chronic rhinitis symptoms like runny nose, sneezing, and stuffiness. 120 adults who haven't gotten relief from standard medications will receive either the laser treatment or a sham procedure. Researche…

This study tests a new epinephrine nasal powder (FMXIN002) against the standard EpiPen injection in 50 healthy adults with allergies. Researchers will measure how quickly and effectively the nasal spray delivers epinephrine into the body and its effects on vital signs. The goal i…

This study tests a new treatment called GNR-127 for people with seasonal allergies to birch pollen. The treatment is a protein that aims to reduce allergy symptoms like sneezing, runny nose, and itchy eyes. The trial involves 150 adults and will check for safety and how well it w…

This study looks at how dupilumab changes the way the nose and blood respond to house dust mites in adults with allergic asthma. Participants will be exposed to dust mites in a special chamber and receive either dupilumab or a placebo. The goal is to understand the drug's effects…

This 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…

This study aims to improve how asthma is diagnosed and treated by developing new tests and targeted therapies. Researchers will enroll 60 adults with asthma to test a special oil additive and measure lung function and quality of life. The goal is to create better tools for managi…

This 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 …
