Platelet-rich plasma for smell loss
Treatments studied
Part of Brain & nervous system clinical trials.
This study tests if injections of platelet-rich plasma (a treatment made from your own blood) can help people who have lost their sense of smell. You may qualify if your smell loss is not caused by injury or blockages in your nose.

This study tests whether a treatment made from your own blood (platelet-rich plasma) sprayed into the nose, with or without insulin, can help restore your sense of smell after an infection. You may be a good fit if smell training hasn't worked and your smell loss is recent.
This study compares two ways to give platelet-rich plasma (PRP) to help people who have lost their sense of smell. PRP is a treatment made from your own blood that may help repair smell nerves.
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.
This trial tests if osteopathic manipulative treatment (OMT) can help people regain their sense of smell after COVID-19. OMT is a hands-on therapy used by osteopathic doctors to improve body function.
This trial studies whether structured smell (olfactory) training can improve ongoing smell problems after COVID-19. It may help people whose sense of smell hasn’t fully returned long after the infection.
This trial tests if platelet-rich plasma injections can help people with long-term smell loss from aging or head injury. It aims to see if this treatment is safe and improves smell function.
