Recruiting studies
- NCT05364125Recruiting
Smell training for people with long-term smell loss
This study tests whether structured smell “training” can improve smell problems. It’s mainly for people who have had reduced smell for more than 6 months but less than 5 years.
Hong KongAges 18–70 - NCT06456008Recruiting
Smell and taste loss registry study
This study tracks patients with smell or taste problems at an ear, nose, and throat clinic to learn more about their conditions. Participants will do simple smell/taste tests and fill out questionnaires.
Leuven, Vlaams-BrabantAges Any age - NCT06115291Enrolling by invitation
Smell training study for adults with smell loss
This study tests whether a daily smell training routine can help improve your sense of smell. It is open to adults with any kind of smell loss or problem, including those with conditions like COVID-19 or head injury, but not certain brain diseases.
Kansas City, KansasAges 18–80 - NCT07041710Recruiting

Smell training plus brain stimulation for long COVID smell loss
This study tests whether a combination of smell training and a type of nerve stimulation can improve persistent smell problems after COVID. It is meant for people who had normal smell before COVID and still struggle with smell changes months later.
Charleston, South CarolinaAges 18–65 - NCT07149428Enrolling by invitation
Deep study of smell loss causes using brain scans
This study uses brain imaging and electrical recordings to understand the brain's role in smell loss from any cause—like COVID, sinus problems, or chemotherapy. You may be eligible if you have any degree of smell loss lasting under a year.
Bethesda, MarylandAges 18–99 - NCT05677321Recruiting
Study how taste and smell differ in alcohol use disorder
This study compares how people with alcohol use disorder and people without it experience taste and smell. It also checks brain activity during taste/smell testing to understand individual differences that may be linked to alcohol use.

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.

Swedish BioFINDER Sleep Study: Brain imaging in RBD and Parkinson's

Common questions
- Are there clinical trials for smell disorder?
- Yes. Clin2 currently lists 9 recruiting smell disorder studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a smell disorder trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a smell disorder trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
