Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Proportion of participants who have achieved target Pyoderma Gangrenosum Area Reduction (PGAR)	The participants will be assessed whether they meet target PGAR at Week 26 based on PGAR score.	Week 26
Secondary	Proportion of participants achieving Physician's Global Assessment (PGA) 0 or 1	The Investigator assesses the global improvement of all ulcers including the target ulcer according to the scales at the specified visits.	Week 6 and Week 26
Secondary	Mean time to occurrence of new PG ulcers	A new PG ulcer is defined as not present at Baseline and not caused by the epithelial bridging of an existing ulcer at Baseline. The time after Baseline when the new lesion was observed will be recorded.	Up to Week 26
Secondary	Change from Baseline in total number of active ulcers	The number of all active PG ulcers will be counted at the specified visits.	Week 26
Secondary	Change from Baseline in Dermatology Life Quality Index (DLQI)	The DLQI will be used to assess the symptoms and the impact of skin problems on quality of life.	Week 6 and Week 26
Secondary	Changes from Baseline in total ulcer area	The change in total ulcer area is assessed.	Week 6 and Week 26
Secondary	Proportion of participants with inflammation reduction as assessed on an Investigator Inflammation Assessment (IIA) Score	The Investigator assesses the inflammation status of the target ulcer at the specified visits according to the scales.	Up to Week 26
Secondary	Mean time to occurrence of a new PG ulcer(s)	Mean time to occurrence of a new PG ulcer(s) is assessed.	Up to Week 52
Secondary	Mean time to healing of target ulcer	The PG Area Reduction (PGAR) is calculated as the percentage area change in the target PG ulcer from Baseline.	Up to Week 52
Secondary	Proportion of participants achieving healing per PGAR for the target ulcer	The PG Area Reduction (PGAR) is calculated as the percentage area change in the target PG ulcer from Baseline.	Week 52
Secondary	Proportion of participants who have achieved target PGAR	The PG Area Reduction (PGAR) is calculated as the percentage area change in the target PG ulcer from Baseline.	Up to Week 26
Secondary	Percentage change in target Pyoderma Gangrenosum (PG) ulcer area	The percentage change in target PG ulcer area is assessed.	Up to Week 26
Secondary	Proportion of participants achieving PGA 0	The Investigator assesses the global improvement of all ulcers including the target ulcer according to the scales at the specified visits.	Week 6 and Week 26
Secondary	Change from Baseline in Pain as measured by Numerical Rating Scale (NRS)	The Numerical Rating Scale of Pain sheet will be filled out in the office by participants at the designated visits.	Week 6 and Week 26
Secondary	Changes from baseline in the proportion of participants taking analgesics	Proportion of participants taking analgesics is assessed.	Week 6 and Week 26
Secondary	Velocities of healing	This is assessed from baseline.	Up to Week 26
Secondary	Proportion of participants achieving ulcer healing as assessed by PGAR	The PG Area Reduction (PGAR) is calculated as the percentage area change in the target PG ulcer from Baseline.	Week 6
Secondary	Proportion of participants achieving PGA 0 of all PG ulcers	The Investigator assesses the global improvement of all ulcers including the target ulcer according to the scales at the specified visits.	Week 52
Secondary	Mean time to relapse of the target PG ulcer	The PG Area Reduction (PGAR) is calculated as the percentage area change in the target PG ulcer from Baseline.	Up to Week 26
Secondary	Mean time to healing as defined by PGAR	The PG Area Reduction (PGAR) is calculated as the percentage area change in the target PG ulcer from Baseline.	Up to Week 26
