Abstract

Background: Anabolic steroids have been reported to improve wound healing. Objective: To determine whether oxandrolone increases the percentage of target pressure ulcers (TPUs) that heal compared with placebo and whether healed ulcers remain closed 8 weeks after treatment. Design: Parallel-group, placebo-controlled, randomized trial conducted from 1 August 2005 to 30 November 2008. Patients, clinical care providers, study personnel, and statisticians were blinded to treatment assignment. (ClinicalTrials.gov: NCT00101361) Setting: 16 inpatient spinal cord injury (SCI) services at Veterans Affairs medical centers. Patients: 1900 prescreened, 779 screened, and 212 randomly assigned inpatients with SCI and stage III or IV TPUs. Intervention: Oxandrolone, 20mg/d(n108), or placebo (n104) until the TPU healed or 24 weeks. Measurements: The primary outcome was healed TPUs. The secondary outcome was the percentage of TPUs that remained healed at 8-week follow-up. Results: 24.1% (95% CI, 16.0% to 32.1%) of TPUs in oxandrolone recipients and 29.8% (CI, 21.0% to 38.6%) in pla-cebo recipients healed (difference,5.7percentage points [CI, 17.5 to 6.8 percentage points]; P0.40). At 8-week follow-up, 16.7% (CI, 9.6% to 23.7%) of oxandrolone recipients and 15.4% (CI, 8.5% to 22.3%) of placebo recipients retained a healed TPU (difference, 1.3 percentage points [CI,8.8 to 11.2 percentage points]; P0.70). No serious adverse events were related to oxandrolone. Liver enzyme levels were elevated in 32.4% (CI, 23.6% to 41.2%) of oxandrolone recipients and 2.9% (CI, 0.0% to 6.1%) of placebo recipients (P < 001). Limitations: Selection of severe wounds may have reduced treatment response. Approximately one third of patients did not complete the study in the treatment and placebo groups. The study was terminated after a futility analysis showed a low probability of detecting a significant difference between the groups. Conclusion: Oxandrolone showed no benefit over placebo for improving healing or the percentage of TPUs that remained closed after 8 weeks of treatment.
