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."}
