Trial outcomes

Primary outcomes

1

Healing

Defined as the proportion of patients with complete re-epithelization, defined as a100% re-epithelialization without any drainage of the target ulcer at week 32.

Time frame
Week 32

Secondary outcomes

1

Physician Global Assessment (PGA)

Assessing the proportion of patients that show target ulcer healing in response to study treatment as measured by achieving PGA between 0 and 1 after treatment with guselkumab at week 32. This scale has been used in previous trials: 0 = total resolution of target ulcer with no signs of active PG 1= almost completely healed target ulcer with only minimal signs of active PG 2 = evidence of target ulcer healing which involves at least 50% of ulcer/ulcer margin 3 = evidence of target ulcer healing which involves less than 50% of ulcer/margin 4 = no evidence of target healing ulcer

Time frame
Week 32
2

Decrease in ulcer area size long-term

The proportion of patients with decrease in ulcer area size of at least 50% after treatment at week 32

Time frame
Week 32
3

Decrease in ulcer area size short-term

The proportion of patients with decrease in ulcer area size of at least 50% after treatment at Week 16

Time frame
Week 16
4

Mean decrease in ulcer area size short-term

Mean decrease in ulcer area size from Week 0 to Week 16

Time frame
Week 16

Other outcomes

1

Evaluation of cytokine gene expression

Cytokine gene expression before and after treatment in skin, wound fluid, saliva and blood samples measured by enzyme-linked immunosorbent assay (ELISA)

Time frame
Week 0 and Week 32
