NCT04134143

Brief Summary

Some people with diabetes get foot ulcers that do not heal. These ulcers can get infected and cause other medical problems. Five patients with these foot ulcers volunteered to participate in the first part of this study (C9T12015, NCT02657876). They are called Cohort 1 in this registration. Cohort 1 received one application (piece) of an experimental skin tissue to make sure it was safe. This study will extend the safety test of the experimental skin tissue. It will find out if it is safe to use more than once to cover non-healing ulcers. This extension will include two more groups, Cohort 2 and Cohort 3. Cohort 2 may get up to 5 applications. Cohort 3 may get up to 10 applications. The number of applications will depend on how well the wound is healing. Participants will be in the study up to one year.
