ClinConnect Summary

This clinical trial is looking at a new treatment called PEP-TISSEEL for adults with chronic radiation ulcers, which are wounds that can develop after radiation therapy. The study aims to see if this treatment is safe and effective compared to a standard product called TISSEEL. The trial is currently not recruiting participants, but when it starts, it will include men and women aged 18 and older who have had radiation therapy and are dealing with specific types of skin ulcers that haven't healed despite other treatments.

To be eligible for the trial, participants must meet certain criteria, such as having a chronic radiation ulcer that is between 1 and 15 square centimeters in size and not infected. They should also have been treated for their condition over six months ago and must be willing to follow the study guidelines and attend all necessary visits. Participants can expect to receive treatment and be monitored closely by healthcare professionals throughout the trial. It's important to know that those with certain medical conditions or who are pregnant or breastfeeding will not be able to participate.
