Recruiting studies
- NCT07867184Enrolling by invitation
Firefighter lung health study
This study looks at how firefighting affects your lungs over time. By tracking your health and exposures, researchers hope to find ways to prevent lung problems in firefighters.
Bethesda, MarylandAges 18–65 - NCT05740683Recruiting
Studies alpha-synuclein and brain symptoms in smell loss
This study looks at whether a specific brain protein (alpha-synuclein) is linked to other neurologic symptoms in people who have long-lasting smell loss. It may help researchers understand what causes smell loss and how it relates to later brain or nerve changes.
CopenhagenAges 55–75 - NCT07151703RecruitingPhase 3
Platelet-rich plasma injections for smell loss
This trial tests whether injecting a concentrated solution from your own blood, called platelet-rich plasma (PRP), into the nose can help restore the sense of smell in people with smell dysfunction. It may offer a new treatment option for those who haven't improved with other therapies.
TaipeiAges 18–80 - 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 - 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+ - NCT06600438Recruiting
Slow walking study for loss of smell
This study tests if a slow walking program can help prevent Parkinson's disease in people with a reduced sense of smell. You will be randomly assigned to a walking group or a control group and followed for 18 months.
LondonAges 40–100 - NCT05384561Recruiting
Training your sense of smell to help after COVID

Common questions
- Are there clinical trials for hyposmia?
- Yes. Clin2 currently lists 7 recruiting hyposmia 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 hyposmia 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 hyposmia 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.
