E.2.2 | Secondary objectives of the trial |
- To determine the efficacy of 4 doses of guselkumab of 200 mg at week 0, 4, 8 and 12 in moderate to severe chronic hidradenitis suppurativa patients, by clinical response rate at week 16 - To assess the short-term the safety and tolerability of guselkumab 200 mg in moderate to severe chronic hidradenitis suppurativa patients at week 16. - To assess the effect of guselkumab on patient reported outcomes measures. - To assess effect of guselkumab changes in levels of inflammatory cytokines and other biomarkers in the peripheral blood.
