ClinConnect Summary

The clinical trial titled "EDX110 - Efficacy and Safety in the Management of Hard-to-heal Wounds" is investigating a new dressing system called EDX110 to see how well it helps heal difficult wounds, specifically diabetic foot ulcers and venous leg ulcers. This study is looking for participants who are at least 18 years old and have a specific type of wound that has been present for 4 to 52 weeks. To qualify, participants must have certain health conditions, such as diabetes and good blood circulation to the affected area, and they must not have had certain recent treatments or health issues that could interfere with the study.

Participants in this trial can expect to receive the EDX110 dressing for their wound, along with regular follow-up evaluations to track their healing progress. It’s important to note that the trial is not yet recruiting participants, and it aims to gather important information about the effectiveness and safety of this new dressing in managing hard-to-heal wounds. If you or someone you know has a qualifying wound and is interested, it might be worth keeping an eye on this study as it progresses!
