ClinConnect Summary

This clinical trial, called O3NPIQ, is looking into the effects of ozone therapy on patients who are experiencing painful nerve damage caused by chemotherapy, a condition known as chemotherapy-induced peripheral neuropathy. The goal is to see if adding ozone therapy can help reduce pain and improve the quality of life for these patients. The trial is currently recruiting participants aged 18 and older, who have been treated for any type of cancer and have been experiencing significant pain for at least three months after finishing their chemotherapy.

To participate, individuals must have a certain level of pain (rated 3 out of 10 or higher) and not have started any new treatments for their pain in the month before joining the trial. Participants will receive ozone therapy and will be monitored to assess how well it works. It's important to note that pregnant women cannot take part in this study, and those with certain medical conditions or other specific issues may also be excluded. Overall, this trial aims to explore a new way to help manage pain for cancer survivors dealing with nerve damage.
