Hyaluronidase Effect on Infusion Set Life
This research study examines the effect of hyaluronidase on the length of time of insulin infusion set wear. The aim of the study is to improve the length of time that an infusion set can be worn by infusing hyaluronidase directly into the insulin infusion site.
Stanford is currently not accepting patients for this trial.
