An interventional study of BU002 and Polyhexanide 0.1% and betaine 0.1% gel in Ulcer Venous and Ulcer Foot, sponsored by Universidad del Desarrollo. Recruiting at 1 site in Chile. Open to participants aged 60 Years and older. Per ClinicalTrials.gov, last updated 2026-05-26.
Sponsored by Universidad del Desarrollo · Not applicable, Interventional, and Treatment
This study is testing a new liquid treatment for people with long-lasting (chronic) wounds, such as venous leg ulcers or diabetic foot ulcers. These wounds can be difficult to heal because they often contain dead tissue and bacteria. The new product is designed to help clean the wound and remove dead tissue, which may help the wound heal better. It will be compared to a commonly used treatment called Polyhexanide gel.
About 80 people aged 60 years or older will take part in this study. Each participant will be randomly assigned (like flipping a coin) to receive either the new treatment or the standard treatment. Neither the participant nor most of the study team will know which treatment is being used during the study to ensure fair results.
The study will last 4 weeks. Participants will attend eleven visits at the wound care center. During these visits, trained nurses will clean and treat the wound. The study team will:
Overall, this study aims to find out if the new treatment can help wounds heal better and more quickly than current standard care.
Taking part in the study is completely voluntary. Participants can leave the study at any time without affecting their usual medical care. All personal and medical information will be kept confidential.
A pure or mixed venous ulcer, or a diabetic, neuropathic, or neuroischemic foot ulcer, greater than or equal to 4 cm² and less than or equal to 30 cm² with critical colonization.
A duration of the ulcer greater than or equal to 2 months and less than or equal to 2 years.
Age over 60 years: due to the higher prevalence of ulcers in adults over 60 years of age.
An ankle-brachial index between 0.6 and 1.3.
