Nasal nerve treatment for chronic rhinitis

This trial tests a new treatment that uses pulsed energy to target a nerve in the back of the nose to help with chronic rhinitis (long-term runny or stuffy nose). It is for people whose symptoms have not been controlled by nasal steroid sprays.

This study uses a nasal allergen provocation test to help diagnose chronic rhinitis more accurately. If you have allergic rhinitis or are a healthy volunteer, you may help researchers learn how well this test works.

This study compares two types of allergy-related nasal treatment: a rinse with azelastine and mometasone versus standard nasal sprays. It aims to see which approach works better for people with long-term (chronic) rhinitis over 6 months.

This study tests a nasal spray (CDA) to see if it can help diagnose irritant-induced rhinitis, a type of chronic stuffy/runny nose not caused by allergies. It compares people with this condition to healthy volunteers.

This study looks at the substances in nasal fluids from people with chronic rhinitis to better understand the condition and find new ways to diagnose it. You provide a free sample and answer some questions.

This trial tests a clear gel containing hyaluronan (a natural moisture-holding substance) applied to the back of the throat and nose to relieve long-term discomfort and inflammation. You'd use the gel regularly for several weeks to see if it reduces throat and nasal symptoms better than a placebo.
