Clinical trials: Parosmia, open to volunteers
Hyposmia, COVID-19
Olfactory Training as a Treatment for Olfactory Dysfunction Post COVID-19
Olfactory dysfunction is a defining symptom of COVID-19 infection. Studies have demonstrated improved olfaction in patients with post infectious olfactory dysfunction after an olfactory training (OT).
- Conditions
- Hyposmia, COVID-19, Parosmia, Anosmia
- Trial name
- OTTODC19 (NCT05384561)
- Testing
- Smell training
- Where
- Canada
- Volunteers
- 70 people

Respiratory Tract Infection, Smell Disorder
Longitudinal Deep Phenotyping of Central Mechanisms in Dysosmia: A Pilot Study Using Electrobulbogram (EBG), Functional MRI (fMRI), and Diffusion-Weighted Imaging (DWI)
Background: Loss of the sense of smell can seriously affect a person's quality of life. The ability to smell can be damaged by many factors, including illnesses, injuries, and exposure to toxic chemicals.
- Conditions
- Respiratory Tract Infection, Smell Disorder, Influenza, Rhinosinusitis
- Trial name
- NCT07149428
- Where
- United States
- Volunteers
- 80 people, healthy volunteers welcome
- Sponsor
- National Institute on Deafness and Other Communication Disorders (NIDCD)
Paraosmia
Randomized Clinical Trial of Intranasal Injection of Platelet-Rich Plasma for Treatment of Parosmia
This randomized clinical trial will evaluate the benefit of platelet-rich plasma (PRP) in the treatment of qualitative olfactory dysfunction (parosmia).
- Trial name
- NCT06283745
- Testing
- Platelet-rich Plasma (PRP), Saline
- Where
- United States
- Volunteers
- 40 people
- Sponsor
- Stanford University
Smell Dysfunction, Olfactory Disorder
Study of Chemosensory Enhancement Through Neuromodulation Training (SCENT for Long COVID)
Persistent smell loss that can include diminished or distorted smell function is a common symptom of long COVID syndrome. There are limited treatment options for long COVID-related smell loss.
- Conditions
- Smell Dysfunction, Olfactory Disorder, Long COVID
- Trial name
- NCT05855369
- Testing
- Trigeminal Nerve Stimulation (TNS), Active Smell Training (ST)
- Where
- United States
- Volunteers
- 145 people
- Sponsor
- Medical University of South Carolina

- Conditions
- Olfactory Dysfunction, Chronic Rhinosinusitis With Nasal Polyps (CRSwNP), Functional Magnetic Resonance Imaging (fMRI)
- Trial name
- NCT07819162
- Where
- Denmark
- Volunteers
- 40 people, healthy volunteers welcome
