E.3 | Principal inclusion criteria |
1. Men and women age 18 to 75 years inclusive at the time of signing the ICF. 2. HS disease duration of at least 3 months before screening. 3. Diagnosis of HS defined as: a. A total of at least 5 inflammatory lesions (AN) at screening AND baseline AND b. Inflammatory lesions present in at least 2 distinct anatomical areas 4. Willingness to avoid pregnancy or fathering children based on the criteria below. a. Male participants with childbearing potential must agree to take appropriate precautions to avoid fathering children (with at least 99% certainty) from screening through 90 days after the last dose of study drug and must refrain from donating sperm during this period. Permitted methods that are at least 99% effective in preventing pregnancy (see Appendix A) should be communicated to the participants and their understanding confirmed. b. Female participants with childbearing potential must have a negative serum pregnancy test at screening and must agree to take appropriate precautions to avoid pregnancy (with at least 99% certainty) from screening through safety follow-up. Permitted methods that are at least 99% effective in preventing pregnancy (see Appendix A) should be communicated to the participants and their understanding confirmed. c. Female participants without childbearing potential (ie, surgically sterile with a hysterectomy and/or bilateral oophorectomy OR postmenopausal, defined as amenorrhea ≥ 12 months prior to screening), confirmed by FSH levels at screening, are eligible. 5. Participants agree NOT to use topical antiseptics (see Section 6.6.2) on the areas affected by HS lesions during the placebo-controlled 16-week treatment period. |
|
E.4 | Principal exclusion criteria |
1. Inability of the participant (or guardian or legally authorized representative) to comprehend the ICF or unwillingness to sign the ICF. 2. Presence of > 20 draining fistulas at screening or baseline. 3. Women who are pregnant (or who are considering pregnancy) or lactating. 4. Participants with concurrent conditions or history of other diseases, as follows: a. Thrombocytopenia, coagulopathy, or platelet dysfunction. b. Any clinically significant medical condition other than HS, as determined by the investigator, that is not adequately controlled with appropriate treatment OR may interfere with the course, severity, or assessments of HS. c. Any other active skin disease or condition (eg, bacterial, fungal, or viral infection) that may interfere with the course, severity, or assessments of HS. d. Active systemic viral infection or any active viral infection that, based on the investigator's clinical assessment, makes the participant an unsuitable candidate for the study. e. Current herpes zoster infection, a history of disseminated herpes simplex, or a history of herpes zoster. f. History of malignancy, including lymphoma and leukemia within 5 years before baseline, other than a successfully treated nonmetastatic cutaneous squamous cell carcinoma, basal cell carcinoma, or localized carcinoma in situ of the cervix. g. Albinism.

E.5 End points |
E.5.1 | Primary end point(s) |
Mean change of abscess and inflammatory nodules (AN) count at Week 16 relative to baseline. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
• Key secondary endpoint: Proportion of participants who achieve HiSCR at Week 16. Hidradenitis suppurativa clinical response is defined as at least a 50% decrease from baseline in AN count with no increase in the number of abscesses or draining fistulas. • Proportion of participants who achieve HiSCR at each visit from Weeks 2 to 12. • Proportion of participants who achieve at least a 75% decrease from baseline in AN count with no increase in the number of abscesses or draining fistulas from Weeks 2 to 16. • Mean change from baseline in the severity of the disease, as assessed by the IHS4 score, from Weeks 2 to 16. • Proportion of participants achieving AN50, AN75, AN90, and AN100 (at least 50%, 75%, 90%, and 100% reduction in AN count relative to baseline, respectively) from Weeks 2 to 16. • Mean change in AN count at Weeks 2 to 12, relative to baseline. • Proportion of participants with a total AN count of 0 to 2 from Weeks 2 to 16. • Mean change in draining fistula count from Weeks 2 to 16, relative to baseline. • Mean change in ANF count from Weeks 2 to 16, relative to baseline.
