Platelet-rich plasma with or without insulin for smell loss
Part of Brain & nervous system clinical trials.
This trial tests whether a treatment made from your own blood (platelet-rich plasma) can help restore your sense of smell after an infection, and whether adding insulin makes it work better. You’ll receive the treatment inside your nose, and the study will compare the two options.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have been diagnosed with a smell disorder that didn’t improve with smell training
- You lost your sense of smell within the last 5 years
- Your smell loss started after an infection
- Your blood platelet count is above 150,000 per microliter
- You don’t have nasal tumors, bleeding disorders, or allergies to insulin or platelet products
- You haven’t used inhaled drugs (like cocaine) in the past 6 months

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.
This study tests whether an injection of your own platelet-rich plasma (a concentrated part of your blood that helps healing) can improve your sense of smell. It is designed for people who have completely lost their smell (anosmia) without a known cause like injury or nasal blockage.
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 tests if a treatment made from your own blood (platelet-rich plasma) can improve smell loss caused by aging or head injury. The goal is to see if it's safe and if it helps people regain some sense of smell.
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.
This trial tests whether steroid nose drops placed in the upper part of the nose, combined with smell training (sniffing different scents), can help people who lost their sense of smell after an infection. The goal is to see if this combination improves smell recovery better than training alone.
