Evaluating the Efficacy of an Absorbent Foam Dressing Containing Silver (Mepilex Ag) Versus the Same Dressing Without Silver Used on Subjects With Venous Leg Ulcers or Mixed Ulcers

Phase 4

Completed

• Conditions: Venous Leg Ulcers; Mixed Leg Ulcers

• Registration Number: NCT01036438
• Lead Sponsor: Molnlycke Health Care AB
