Abstract

Objective. The results of the single-arm, open-label extension phase of the Grafix (cryopreserved placental membrane; CPM; Osiris Therapeutics, Inc, Columbia, MD) multicenter, blinded, randomized, controlled clinical trial for chronic diabetic foot ulcers (DFUs) is reported. Materials and Methods. Twenty-six patients in the standard wound care (SWC) arm whose DFUs did not close in the blinded phase chose to receive weekly applications of the CPM in an open-label extension phase. Results. In the extension phase, 17 (65.4%) patients closed their wounds in a median of 34 days and 3 visits. There were fewer total adverse events (AEs) (24 CPM vs. 52 SWC) and index wound-related infections (5 CPM vs. 12 SWC) during the CPM application compared with the number of AEs for the same patients during the SWC treatment in the blinded phase of the trial. Conclusions. These results corroborate the benefits of this CPM combined with SWC over SWC alone for chronic DFUs previously reported for the blinded randomized phase of the trial, which directly relate to lower health care costs.
