  1. If an ulcer is judged healed on or before Week 24, then healing should be confirmed by a blinded assessor as soon as possible, and within 4 days. If the ulcer breaks down within 4 weeks of first being judged healed, the participant should continue in the study. If the ulcer remains healed, the participant needs to have 12 Week and 24 Week visits – unless these have already been done.
