Note: The study comprises participants with HS regardless of prior HS therapy, including both treatment-naive participants and treatment-IR participants (defined as those who had inadequate response, intolerance, or contraindication to prior topical or systemic medications for HS [excluding washes and antiseptics containing chlorhexidine, triclosan, iodine, etc]).\n- Have mild to moderate HS (Hurley Stage I or II) with a total AN count of at least 4, with no draining tunnels, and affecting at least 2 distinct anatomical areas at the screening and Day 1 visits. Note: Anatomical areas include but are not limited to the left or right axilla, left or right inguinocrural fold, and left or right inframammary areas.\n- Agreement to not use topical or systemic antibiotics for treatment of HS during the DBVC period and Weeks 16 through 20 of the OLE period.\n- Agreement to not use topical antiseptics, including washes and leave-on products with ingredients such as chlorhexidine, povidone iodine, sodium hypochlorite, diluted bleach, or benzoyl peroxide, on the areas affected by HS lesions during the DBVC period and Weeks 16 through 20 of the OLE period. Note: Over-the-counter soap and water are allowed.\n- Willingness to avoid pregnancy or fathering children based on the criteria below. Refer to protocol for all details."}

Note: Use of corticosteroid inhalers and intranasal sprays is allowed. d. 4 weeks for surgical, laser, or any phototherapy intervention in areas with HS lesions. e. 2 weeks for other systemic therapies for HS (eg, zinc, vitamin D, retinoids, antihypertensives, antihyperglycemics, and antiandrogens such as acitretin, isotretinoin, metformin, spironolactone, and finasteride) with potential therapeutic impact. f. 2 weeks for systemic antiinfective therapy for HS. g. 2 weeks for intralesional therapy for HS. h. 2 weeks for any topical therapy for HS (eg, topical antiseptics such as chlorhexidine, benzoyl peroxide, sodium hypochlorite, povidone iodine, or benzoyl peroxide; topical antibiotics; topical corticosteroids; topical calcineurin inhibitors; or other topicals). Note: Use of topical therapy for dermatologic diseases other than HS (eg, AD, psoriasis) is allowed for areas not being treated for HS. The total BSA involvement for other dermatologic diseases should not interfere with the safety of the participant or the HS assessments. i. 2 weeks or 5 half-lives, whichever is longer, for strong systemic CYP3A4 inhibitors. j. 2 weeks for immunizations with live-attenuated vaccines. Note: Non–live-attenuated vaccinations (eg, flu, COVID-19) are allowed. k. 2 weeks for any opioid treatment. l.

Any other concomitant skin disorder that may interfere with and confound the evaluation of HS or compromise participant safety. b. Current and/or history of active TB . Or current and/or history of latent TB unless adequately treated. c. Immunocompromised (eg, lymphoma, immunosuppression associated with organ transplantation, Wiskott-Aldrich syndrome). d.
