End Notes

1. Subjects received topical treatment with either Filsuvez or a placebo gel on partial-thickness wounds every 1 to 4 days for a total of 90 days. Treated wounds were covered with non-adhesive dressings. Following completion of the double-blind phase, all subjects received FILSUVEZ for a total of 24 months during the open-label phase. [1]
2. If a Filsuvez- treated wound becomes infected, discontinue treatment to that wound until the infection has resolved. [1]
3. Apply Filsuvez to cleansed wounds with wound dressing changes until the wound is healed. [1]
4. One tube of FILSUVEZ covers up to 250 cm^2 surface area. A tube of Filsuvez is for one-time use and should be discarded once opened [1, 12]
