evaluating the efficacy of neothelium ft in the treatment of chronic open wounds

Conditions: Open Wound

Summary: this is a randomized controlled crossover trial evaluating the efficacy of neothelium ft in conjunction with standard of care vs. standard of care alone in treating chronic open wounds.

this research will take place across multiple medical centers, where both researchers and participants will know which treatment is being used (open label). patients who agree to participate and meet the study requirements during screening will be randomly assigned to one of two groups: either standard of care (soc) alone, or soc plus neothelium ft. the study includes a crossover component for subjects in the soc arm. at treatment visit 13 (approximately 84 days post-randomization), soc arm subjects not having achieved complete wound closure, and still meeting the inclusion/exclusion criteria, are eligible to cross over to the ip arm (soc plus neothelium ft). crossover subjects will begin ip arm treatment with weekly neothelium ft applications for up to 12 treatment visits. the subject will continue follow-up per the original schedule. as this is a post-marketing study, it will gather information regarding the efficacy of treatment while also supporting insurance reimbursement decisions. all subjects will complete two-week screening phase prior to being randomized into a treatment arm. treatment arms will consist of neothelium ft in conjunction with standard of care, vs. standard of care alone. the primary endpoint will be the percentage of target ulcers that achieve complete wound closure within 12 weeks. secondary endpoints consist of wound percentage area reduction rates and pain assessment.
