Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: AviClear Group; Participants will be in this group for up to 43 weeks.	Device: AviClear; Participants will receive as many as 4 treatments, each treatment lasts approximately 10 minutes, with intervals of up to 5 weeks apart. The treatments will be conducted in person. Participants will be followed at approximately week 5 post-treatment completion (via phone) at 12 weeks and 24 weeks post treatment completion onsite. This is a 1726 nanometer laser treatment

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in HiSCR50 as measured by percentage of participants	Percentage of participants achieving Hidradenitis Suppurativa Clinical Response 50 (HiSCR50, where HiSCR50 is defined as at least a 50% reduction from baseline in abscess and inflammatory nodule (AN) count, with no increase from baseline in abscess or draining fistula count.	Baseline, up to 24 weeks (after final treatment)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in pain as measured by Visual Analogue Scale Pain Rating Scale	Score range from 0 to 10. Higher score indicates more pain.	Baseline, up to 24 weeks (after final treatment)
Change in number of lesions	Number of lesions	Baseline, up to 24 weeks (after final treatment)
Change in IHS 4	The International Hidradenitis Suppurativa 4 (IHS 4) score is calculated as follows: number of nodules (multiplied by 1) + number of abscesses (multiplied by 2) + number of draining tunnels (multiplied by 4). A total score of 3 or less signifies mild, 4 to 10 signifies moderate, and 11 or higher signifies severe disease.	Baseline, up to 24 weeks (after final treatment)
Change in number of Patient's stage category as measured by Hurley Stage	The unit of measure for this outcome is the change in number of patient's stage category. The different Hurley Stages are as follows: Patient's stage category I: Single of multiple abscess formation without sinus tracts and cicatrization Patient's stage category II: Recurrent single or multiple abscesses, widely separated, with limited sinus tracts and cicatrization Patient's stage category III: Diffuse or near-diffuse involvement of multiple interconnected tracts and abscesses across an entire area	Baseline, up to 24 weeks (after final treatment)
