About the trial

What the trial wants to find out

This study is open to adults with hidradenitis suppurativa who took part in a previous clinical study of a medicine called spesolimab. Participants who completed treatment can join this study.

Read full original descriptionShow less

The purpose of this study is to find out how safe spesolimab is and whether it helps people with hidradenitis suppurativa in the long-term. Participants are in this study for about 2 years and 4 months. For 2 years, participants visit the study site every 2 weeks to get spesolimab injections under the skin. At study visits, doctors check the severity of participants' hidradenitis suppurativa and collect information on any health problems of the participants.

The 2 groups in the trial

  • Prior Placebo (PP)Treatment being tested

    Participants in the placebo arm of the 1368-0052 Proof of Concept Clinical (PoCC) trial received an initial 1200 mg intravenous (i.v.) loading dose of spesolimab plus subcutaneous (s.c.) placebo at Visit 1, followed by 600 mg s.c. doses of spesolimab every two weeks for the next 12 weeks. Further dosing was based on changes in HS-PGA grade assessment from baseline to week 12.

    Treatment: Spesolimab 1200 mg, Spesolimab 600 mg, and Placebo matching 600 mg Spesolimab

  • Prior Spesolimab (PS)Treatment being tested

    Participants in the active arm of the 1368-0052 Proof of Concept Clinical (PoCC) trial received an initial 600 mg subcutaneous (s.c.) loading dose of spesolimab plus intravenous (i.v.) placebo at Visit 1, followed by 600 mg s.c. doses of spesolimab every two weeks for the next 12 weeks. Further dosing was based on changes in HS-PGA grade assessment from baseline to week 12.

    Treatment: Spesolimab 600 mg and Placebo matching 1200 mg Spesolimab
