About

This study is open to adults with moderate to severe hidradenitis suppurativa (HS). The purpose of this study is to find out whether a medicine called spesolimab helps people with HS. People who have previously taken specific medicines such as immunosuppressive biologics other than Tumor necrosis factor (TNF) inhibitors cannot take part.

This study has 2 parts. In Part 1, participants are divided into 4 groups of almost equal size. 3 groups get different doses of spesolimab, 1 group gets placebo. All participants get injections into a vein or under the skin. Placebo injections look like spesolimab injections, but do not contain any medicine. Every participant has an equal chance of being in each group. In the beginning, participants get the study medicine every week and later every 2 weeks. After 4 months, participants in the placebo group switch to spesolimab treatment.

In Part 2, participants are divided into 2 groups. One group gets a suitable dose of spesolimab that was found in Part 1 of the study. The other group gets placebo. After 4 months, participants in the placebo group switch to spesolimab treatment.

Participants join only one of the two parts. They are in the study for about 1 year. During this time, they visit the study site in the beginning every week and later every 2 weeks. Some of the visits can be done at the participant's home instead of the study site. The doctors regularly check participants' HS symptoms. The results are compared between the groups to see whether spesolimab works. The doctors also regularly check participants' general health and take note of any unwanted effects.

Main endpoints for Part 2 will be supported by Part 1 results available at time of primary analysis.

  2. Signed and dated written informed consent in accordance with International Council on Harmonisation-Good clinical practice (ICH-GCP) and local legislation prior to admission to the trial.
  3. Moderate to severe HS.
  4. HS lesions in at least 2 distinct anatomic areas.
  5. Biologic naive or Tumor Necrosis Factor inhibitor (TNFi)-exposed for HS.
  6. For biologic naïve, inadequate response to an adequate course of appropriate oral antibiotics for treatment of HS in the last 1 year prior to the Baseline visit, as per investigator discretion. All participants must have previous exposure to antibiotics for HS.
  7. Total AN count of greater than or equal to 5.
  8. Total dT count of at least 1 at Baseline visit. Further inclusion criteria apply.

Exclusion criteria

  1. Participants who must or wish to continue the intake of restricted medications or any drug considered likely to interfere with the safe conduct of the trial.
  2. Prior exposure to any immunosuppressive/immunomodulatory biologic other than TNFi for HS.
  3. Prior exposure to Interleukin 36 receptor (IL-36R) inhibitors including spesolimab.
  4. Treated with any investigational device or investigational drug of chemical or biologic nature within a minimum of 30 days or 5 half-lives of the drug, whichever is longer.
  5. Women who are pregnant, nursing, or who plan to become pregnant while in the trial.
  6. Participants with history of allergy/hypersensitivity to the systemically administered trial medication agent or its excipients.
  7. Participants with a transplanted organ (with exception of a corneal transplant >12 weeks prior to screening) or who has ever received stem cell therapy (e.g., Remestemcel-L).
  8. Participants with any documented active or suspected malignancy or history of malignancy within 5 years prior to the screening visit, except appropriately treated basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ carcinoma of uterine cervix.

Further exclusion criteria apply.
