Outcome Measures

Primary Outcomes (1)

  • The percentage change of ulcer area 8 weeks after initiation of therapy.

    The wound area is measured at week 0 (A0) and at 8 weeks (A8). From these measurements, the percentage (%) change of the wound area in relation to the start time (week 0) is determined from the following formula: (A0-A8)/A0\*100.

    8 weeks

Secondary Outcomes (2)

  • Pain is evaluated by visual analogue scale (VAS).

    8 weeks

  • Occurrence of suspected unexpected serious adverse reactions (SUSAR) and serious adverse events (SAE)

    8 weeks
