Significance: Diabetic foot ulcers (DFU) significantly add to global economic, social, and clinical burdens. Healing a DFU fast and well limits complications that can lead to lower extremity amputation, morbidity, and mortality.Recent Advances: Many promising topical DFU healing agents have been studied in randomized clinical trials (RCT), but only one, becaplermin, has been cleared for this use by the United States Food and Drug Administration (FDA).Critical Issues: This critical review of DFU topical healing RCTs summarizes issues identified in their design and conduct, highlighting ways to improve study quality so researchers can increase the likelihood of RCT success in propelling effective topical DFU healing agents toward clinical use. Key issues include (1) inadequate sample size, (2) risk of bias, (3) irrelevant or unreported inclusion criteria, (4) substandard outcome measures, (5) unmatched group characteristics that predict nonhealing at baseline, (6) unequal or uncontrolled concurrent interventions or standard of care, (7) heterogeneous subject or DFU samples (8) unblinded allocation, treatment, or outcome measures, or (9) inadequate follow-up for clinical relevance. These can add bias or unexplained variability to RCT outcomes, limiting clinical or statistical significance and accuracy of results.Future Directions: This critical review summarizes ways to overcome these deficiencies to optimize DFU clinical trial design and conduct. It provides a blueprint for future excellence in RCTs testing safety and efficacy of topical DFU healing agents and smoothing the path to their clinical use.
