New shot could ease painful skin condition
NCT ID NCT06411379
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a drug called sonelokimab in 418 adults with moderate to severe hidradenitis suppurativa, a skin condition that causes painful lumps and abscesses. Participants received either the drug or a placebo injection for 16 weeks. The goal was to see if sonelokimab reduces the number of inflamed lumps and draining tunnels by at least 75%.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Sonelokimab (a drug injected under the skin)
- What this could lead to
- If it works, this could provide a new treatment option for people with moderate to severe hidradenitis suppurativa, reducing painful lumps and abscesses.
- What could go wrong
- This is a completed Phase 3 trial, but results are not yet public. The drug may not work better than placebo, and side effects are possible. It is not a cure, and ongoing treatment may be needed.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Participants must be at least 18 years of age at the time of signing the informed consent. 2. Participants who are diagnosed with hidradenitis suppurativa as determined by the investigator and have a history of signs and symptoms of hidradenitis suppurativa for at least 6 months before signing the informed consent. 3. Participants who have had an inadequate response to appropriate systemic antibiotics for treatment of hidradenitis suppurativa (or demonstrated intolerance to, or had a contraindication to, systemic antibiotics for treatment of their HS), in the investigator's opinion. 4. Participants who have a total AN count of ≥5. 5. Participants who have HS lesions present in ≥2 distinct anatomical areas, at least one of which must contain single or multiple fistulas (ie, be Hurley Stage II or III). Exclusion Criteria: 1. Participants with a known hypersensitivity to sonelokimab or any of its excipients. 2. Participants with any other active skin disease or condition that may, in the opinion of the investigator, interfere with the assessment of HS. 3. Participants with underlying conditions that, in the opinion of the investigator, potentially places the participant at unacceptable risk. 4. Participants with current severe or uncontrolled disease(s) that put(s) the participant at increased risk in the investigator's opinion, would preclude the participant from adhering to the protocol or completing the study per protocol. 5. Participants with any other known autoimmune disease or any medical condition that in the opinion of the investigator would interfere with an accurate assessment of clinical symptoms of HS. 6. Participants with a gastrointestinal condition including inflammatory bowel disease or diagnosis of ulcerative colitis or Crohn's disease.
