* Participant with a history of signs and symptoms consistent with HS for at least 1 year prior to baseline.
* Participant must have HS lesions present in at least 2 distinct anatomic areas, one of which must be Hurley Stage II or Hurley Stage III.
* Participant must have had an inadequate response after at least one-month of oral antibiotic treatment for HS, as assessed by the Investigator.
* Participant must have a total AN count of ≥5 at the baseline visit.
* Participant must have a draining tunnel count of ≤20 at the baseline visit.
* Participant must be willing and able to complete the diary for the duration of the study as required by the study protocol.
* Contraceptive use by men with a partner of childbearing potential and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.

Exclusion Criteria

* Participant with any other active skin disease or condition (eg, bacterial, fungal, or viral infection) that may interfere with assessment of HS.
* Any active or chronic infection requiring systemic treatment (eg, antibiotics, antivirals, antifungals, antihelminthics) within 30 days prior to baseline.
* Known history of or suspected significant suppressed immune response, including history of invasive opportunistic or helminthic infections despite infection resolution or otherwise recurrent infections of abnormal frequency or prolonged duration.
* Participant with history of solid organ transplant.
* Participant with history of splenectomy.
* Participant with history of any malignancy or lymphoproliferative disease, except if the participant has been free from disease for ≥5 years. Successfully treated non-metastatic cutaneous squamous cell carcinoma, basal cell carcinoma, or localized carcinoma in situ of the cervix are allowed.
* Participant with a diagnosis of chronic immune-mediated, inflammatory conditions other than HS
* Participant with family history of sudden death or long QT syndrome.
* Participant with history of congenital or drug-induced long QT syndrome.
* Participant with congestive heart failure (New York Heart Association Class 2 to 4), greater than Class 1 angina pectoris, acute coronary syndrome within prior 6 months, known structural heart disease.
* Participant with history of any major cardiovascular events (eg, myocardial infarction, unstable angina pectoris, coronary revascularization, stroke, or transient ischemic attack) at any time prior to screening.
* Participant with history of ventricular fibrillation, ventricular tachycardia, torsades de pointes, atrial fibrillation, syncope not explained by non-cardiac etiology.
* Participant with uncontrolled hypertension defined as consistent systolic blood pressure ≥150 mmHg or consistent diastolic blood pressure ≥90 mmHg despite antihypertensive medication.
* Participant received prescription topical therapies for the treatment of HS within 14 days prior to the baseline visit.
* Prior or active treatment with any systemic biologic (anti-TNF) therapy, anti-IL17 therapy, anti-IL1/anti-IL1 receptor therapy except for up to 20% of the total study population. Furthermore, this 20% of biologic-experienced participants must fulfilled one or more of the following conditions:

* Discontinued due to treatment related toxicity and/or
* Discontinuation is not related to lack or loss of therapeutic response.
