Overview
Brief Summary

Outcomes
Primary Outcomes
Clinical Responder Rate at Period 1: Week 16
Time Frame: Week 16
Proportion of study participants achieving a clinical response in Hidradenitis Suppurativa - Physician Global Assessment (HS-PGA) score An HS-PGA responder in period 1 was a participant who had an initial HS-PGA score of at least 3 at baseline (Day 1, inclusion criterion) that decreased by at least 2 points. The six-point Physician Global Assessment (PGA) (scores range from 0-5) based on the number of HS lesions ranges from clear to very severe.
Secondary Outcomes
- Clinical Responder Rate Period 1 at Week 2, 4, 8 and 12(Week 2, 4, 8 and 12)
- Pharmacokinetics (PK): Ctrough for CJM112 Period 1 and Period 2(Week 16 and Week 44)
- Pharmacokinetic Profile: T1/2 The Terminal Elimination Half-life for Period 1 & Period 2/End of Study(Week 16 (period 1), Week 44 (End of Study Period 2))
- Total Interleukin-17A (IL-17A Homodimer) in Serum at Pre-dose and Post-dose for Period 1 & Period 2(Pre-dose (Period 1 Day 1 & Period 2 Day 113), Post-dose Period 1(Day 99) and post-dose Period 2 (Day 211))
- Immunogenicity - Incidence of ADA-positive and ADA-negative in Participants With or Without Pre-existing Antibodies in Period 1 and Period 2/End of Study(Week 16 (period 1), Week 44 (End of Study Period 2))
