Is this trial a fit for you?

Likely a good fit

Adults with moderate to severe hidradenitis suppurativa affecting at least two body regions and a baseline AN count of 5 or more, who have had inadequate or intolerant responses to systemic antibiotics.

Probably not a fit

Patients with HS outside the eligible criteria or who do not respond to duvakitug may not experience benefit and could face treatment-related risks.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a Phase 2b, multicenter, randomized, double-blind, placebo-controlled trial with three active dose groups and a placebo arm. Participants have at least 6 months of hidradenitis suppurativa with lesions in two distinct areas and a baseline abscess and inflammatory nodule count of 5 or more. The study uses a dose-ranging design over an initial 16-week double-blind period, followed by an active extension and a long-term extension, with follow-up up to 145 weeks total. Primary aims focus on safety and efficacy across multiple doses for adult HS patients who have not responded adequately to antibiotics or have intolerance to antibiotics. Investigators will monitor adverse events and treatment effects across diverse geographic sites educated by a multinational framework.

Why it matters

Potential benefit: If successful, participants and future patients could experience better control of HS lesions and symptoms with a new medication option.

How similar studies have gone: Past studies applying similar anti-inflammatory biologics in HS have shown potential benefits, though results can vary by dose and patient population.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Participants with a history of signs and symptoms consistent with hidradenitis suppurativa (HS) for at least 6 months prior to Baseline Visit
* Participants must have HS lesions present in at least 2 distinct anatomic areas (eg, left, and right axilla; or left axilla and left inguino-crural fold), with at least 1 body site being Hurley Stage II or III.
* Participant must have a total abscess and inflammatory nodule (AN) count of ≥5 at the Baseline Visit.
* Participants must have had an inadequate response to a course of a systemic antibiotics for treatment of HS, exhibited recurrence after discontinuation of antibiotics or demonstrated intolerance to antibiotics, or has a contraindication to systemic antibiotics for treatment of their HS as assessed by the Investigator through participant interview and review of medical history.
* Participants must have a prior HS treatment history consistent with the following:

  * For the biologic and immunosuppressive small molecule-naïve subgroup, participants must have no history of treatment with any approved or investigational biologic therapy or small molecule immunosuppressive therapy with potential efficacy for HS.
  * For the biologic and immunosuppressive small molecule-experienced subgroup, participants must have a history of treatment with at least 1 biologic or immunosuppressive small molecule therapy with potential efficacy for HS.

Exclusion Criteria:

* Participants are excluded from the study if any of the following criteria apply:
* Any other active skin disease or condition (eg, bacterial, fungal, or viral infection) that may interfere with assessment of HS.
* History of systemic hypersensitivity or anaphylaxis to any biologic therapy
* History of recurrent or recent serious infection
* Known history of or suspected significant current immunosuppression
* History of solid organ transplant or stem cell transplant.
* History of splenectomy
* History of malignancy or suspicion of malignancy within 5 years prior to the Screening Visit (except for in situ cervical carcinoma that has been treated by surgery and completely cured, or basal cell carcinoma or squamous cell carcinoma that has been excised and completely cured)
* History within the 2 years prior to Baseline Visit of prescription drug or substance abuse, including alcohol, considered significant by the Investigator.
* Any medical or psychiatric condition which, in the opinion of the Investigator could be considered uncontrolled, unstable, or likely to progress in a clinically relevant manner and may present an unreasonable risk to the study participants as a result of his/her participation in this clinical study, may make participant's participation unreliable, or may interfere with study assessments.
* Any other medical condition or severe, concomitant illness, including psychiatric illness and substance abuse, that may present an unreasonable risk to the study participants, make participants unreliable, or may interfere with study assessments.
