Recruiting studies
- NCT07681973Recruiting
Smell training for loss of smell in sinus patients
This study tests whether smell training can improve your sense of smell and affect your immune system. It is for people with chronic sinus inflammation and nasal polyps who have lost their sense of smell.
Cleveland, OhioAges 18 years+ - NCT05364125Recruiting
Smell training for people with long-term smell loss

Hong KongAges 18–70 - NCT07021040Recruiting
Nasal biopsy study for Alzheimer's and smell disorders
This study takes a small tissue sample from inside your nose to look for changes linked to Alzheimer's disease or smell problems. It may help us better understand how these conditions affect the brain.
Durham, North CarolinaAges 18 years+ - NCT06733636Recruiting
Smell training for older adults with smell loss
This study tests whether a special device can help older adults regain their sense of smell through regular training with different scents. It is designed for people who have lost smell due to aging or other causes, not from birth.
Baltimore, MarylandAges 60 years+ - NCT06892704Recruiting
Dupilumab smell restoration study for CRSwNP
This study tests if the medication dupilumab can improve smell loss in people with chronic sinusitis and nasal polyps. Researchers will check if blocking in the nose and electrical signals in the brain can predict who will benefit.
Chicago, IllinoisAges 18–65 - NCT05670496Recruiting
NIDCD medical data and sample collection for communication disorders
This study collects medical information and specimens to support research on problems with hearing, balance, taste, smell, voice, speech, and language. It may help you (or your child) get additional evaluation and follow-up through NIDCD, especially if your clinician thinks it could be useful.
Bethesda, MarylandAges 2–99 - NCT06776042Recruiting
Nasal polyps and smell loss study
This study looks at why people with nasal polyps lose their sense of smell and how it might come back. You may be able to join if you have had nasal blockage, runny nose, smell loss, or facial pain for at least 12 weeks, have polyps seen inside your nose, and are using a steroid spray regularly.
