Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in International Hidradenitis Suppurativa Severity Score System (IHS4) score from Day 0 by time point	The International Hidradenitis Suppurativa Severity Score 4 (IHS4: developed by the European Hidradenitis Suppurativa Foundation Investigator Group),IHS4 Score=(Nodule Count) + (Abscess Count*2) + (Draining Tunnel Count *4).; IHS4 score uses a range grades: Mild=0-3; Moderate=4-10; Severe =11.	Week 8
Secondary	Change in International Hidradenitis Suppurativa Severity Score System (IHS4) score from Day 0 by time point	The International Hidradenitis Suppurativa Severity Score 4 (IHS4: developed by the European Hidradenitis Suppurativa Foundation Investigator Group),IHS4 Score=(Nodule Count) + (Abscess Count*2) + (Draining Tunnel Count *4).; IHS4 score uses a range grades: Mild=0-3; Moderate=4-10; Severe =11.	From Day 0 until Day 56
Secondary	Change in modified Sartorius Score (mSS) from Day 0 by time point	The mSS is a summation of HS lesions based on a number of factors including anatomical region, number and type of lesions, distance between relevant lesions and lesions clearly separated by normal skin in each region measured as HS clinical parameters. The scale title for mSS is points. The mSS has a minimum value of 0 and no upper limit. The higher the score the more severe is the disease/worse is the outcome.	From Day 0 until Day 56
Secondary	Change in Hidradenitis Suppurativa Clinical Response (HiSCR) from Day 0 by time point	The definition for response to treatment based on HiSCR relative to Baseline was: at least 50% reduction in abscesses and inflammatory nodule (AN) count (over all anatomical regions) with no increase in number of abscesses and in number of draining fistulas.	From Day 0 until Day 56
Secondary	Change in Hidradenitis suppurativa-Physician Global Assessment (HS-PGA) score from Day 0 by time point	Hidradenitis Suppurativa - Physician's Global Assessment (HS-PGA)classifies patients' severity into six categories:clear, minimal, mild, moderate, severe, and very severe, based on the number and quality of inflammatory lesions.	From Day 0 until Day 56
Secondary	Changes of active lesions (number of inflammatory nodules, abscesses, fistulas, and abscess overflow score) from Day 0 by time point.		From Day 0 until Day 56
Secondary	Change in Dermatology Life Quality Index (DLQI) score from Day 0 by time point	A score is documented for each of the 10 DLQI items, ranging from 0 to 3 for each item. The scale title for DLQI is points. The total score is the sum of the responses to all 10 DLQI items, ranging from the minimum of 0 points to the maximum of 30 points. A higher score corresponds to worse health related quality of life/outcome.	From Day 0 until Day 56
Secondary	7. Change in Dermatology visual analog scale (VAS) score from Day 0 by time point.		From Day 0 until Day 56]
Secondary	Safety of BDB-001 injection in the treatment of patients with HS will be assessed	Number of participants with treatment-related adverse events as assessed by CTCAE v5.0.	From Day 0 until Day 77
