Safety Study of Topical Doxycycline Gel for Adult Diabetic Lower Extremity Ulcers

Completed · Phase 2 · Has a placebo group

Conditions studied: Diabetic Foot Ulcer

In brief

This study is a double-blind, one center, two-arm study with a two (2) week Run-In, evaluating the efficacy of a once-daily administration of NanoDOX™ Hydrogel topically applied to diabetic ulcers in concert with professionally administered Standard of Care (SOC) procedures as described by Standard Operating Procedure(s) of the Department of Veterans Administration Hospitals. During the run-in period patients with infected wounds will receive oral antibiotic and not be included in the topical portion of the study until the infection is shown by wound fluid analysis to be resolved. Following a two (2) week Run-In of all patients to receive SOC treatment for diabetic ulcers, patients would have either the investigational material or the placebo hydrogel applied as a part of their wound care. Each patient would receive 1.5 gm packets of either the test article or the placebo hydrogel for a once-daily home treatment accompanied by a dressing change.
