Platelet-rich plasma with or without insulin for smell loss after infection
Part of Brain & nervous system clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have lost your sense of smell within the last 5 years.
- Your smell loss started after an infection (like a cold or flu).
- You have tried smell training exercises but they haven't worked well enough.
- Your platelet count is over 150,000 (a simple blood test can check this).
- You have not had a head injury or sinus surgery, and you do not use cocaine or other inhaled drugs.

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 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 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 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 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.
This trial tests whether injecting a concentrated part of your own blood (platelet-rich plasma) into your nose can help improve a distorted sense of smell called parosmia. You will also do smell training at home, which is the current standard care.
