Eligibility
Key inclusion criteria
- Participants with a history of signs and symptoms consistent with hidradenitis
suppurativa (HS) for at least 1 year prior to Baseline.

- Participants must have HS lesions present in at least 2 distinct anatomic areas (eg,
left and right axilla; or left axilla and left inguinocrural fold), one of which must
be Hurley Stage II or Hurley Stage III.

- Participant must have had an inadequate response to a trial of an oral antibiotic for
treatment of HS, exhibited recurrence after discontinuation of antibiotics,
demonstrated intolerance to antibiotics, or has a contraindication to oral antibiotics
for treatment of their HS as assessed by the Investigator through participant
interview and review of medical history.

- Participants must be either biologic and small molecule immunosuppressive-naïve or
TNF-experienced.

- Participant must have a total abscess and inflammatory nodule (AN) count of =3 at the
Baseline visit.

- Participant must have a draining tunnel count of =20 at the Baseline visit.

- Participant must have a C-reactive protein (CRP) >3 mg/L at the screening visit.

- Participant who is a candidate for systemic treatment per Investigator's judgment.
Minimum age
18 Years
Maximum age
70 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
- Any other active skin disease or condition (eg, bacterial, fungal or viral infection)
that may interfere with assessment of HS

- History of recurrent or recent serious infection

- Known history of or suspected significant current immunosuppression

- History of solid organ transplant

- History of splenectomy

- History of moderate to severe congestive heart failure

- Receipt of a live vaccine 12 week prior to Baseline visit or receipt of a killed
vaccine 2 weeks prior to Baseline visit

- History of demyelinating disease (including myelitis) or neurologic symptoms
suggestive of demyelinating disease

- Participants with a history of malignancy or lymphoproliferative disease other than
adequately treated or nonmetastatic squamous cell carcinoma, or nonmetastatic basal
cell carcinoma of the skin that was excised and completely cured

- Participants with a diagnosis of inflammatory conditions other than HS

- Presence of active suicidal ideation, or positive suicide behavior or participant has
a lifetime history of suicide attempt, or participant has had suicidal ideation in the
past 6 months as indicated by a positive response using the screening or Baseline
version of the Columbia-Suicide Severity Rating Scale (C-SSRS) or as assessed by the
Investigator through participant interview and review of medical history

- A history of an adverse event (AE) to anti-TNF therapy (examples include, but are not
limited, to serum sickness or anaphylaxis) for an HS or non-HS indication that would
contraindicate readministration of an anti-TNF class therapy

- Sensitivity to any of the study interventions, or components thereof, or drug or other
allergy that, in the opinion of the Investigator, contraindicates participation in the
study

- Female participants who are breastfeeding or considering becoming pregnant during the
study

- History (within last 2 years prior to Baseline) of prescription drug or substance
abuse, including alcohol, considered significant by the Investigator

- Laboratory exclusion criteria apply
