Inclusion criteria
The participants must be at least 18 years of age at the time of signing the ICF.
Study participants must have a diagnosis of HS based on clinical history and physical examination for at least 6 months prior to the baseline visit; diagnosis must be verifiable through medical notes and documentation.
Study participants must have HS lesions in at least 2 distinct anatomic areas (eg, left and right axilla), 1 of which must be at least Hurley Stage II or Hurley Stage III at both the Screening and Baseline visits.
Study participants must have moderate to severe HS defined as a total of ≥ 5 inflammatory lesions (ie, number of abscesses plus number of inflammatory nodules) at both the Screening and Baseline visits.
Study participants must have had a history of inadequate response, intolerance or contraindication to a course of systemic antibiotics for treatment of HS at the Screening Visit as assessed by the investigator.
Participants agree to daily use of topical antiseptics on the areas affected by HS lesions while on study treatment. Allowable antiseptic washes are limited to one of the following: chlorhexidine gluconate, benzoyl peroxide, benzalkonium chloride, benzethonium chloride, or dilute bleach in bath water.
Participants entering the study while undergoing concomitant treatment with systemic antibiotics (as specified in the protocol) must be on a stable dose. A stable dose is defined as a dosage or regimen that has remained unchanged for at least four weeks prior to baseline and is expected to remain unchanged for at least the first 16 weeks of the study.
Female participants must be not of childbearing potential or permanently sterilized (e.g., tubal occlusion, hysterectomy, bilateral salpingectomy) or, if of childbearing potential (and engaged in sexual activity that could result in procreation), must be willing to use a highly effective method of contraception up to 40 weeks after the last administration of the investigational medical product (IMP) and have a negative pregnancy test prior to the first dose. The following methods are considered highly effective when used consistently and correctly:
Note: Participants who use abstinence as a form of birth control must agree to abstain from heterosexual intercourse until 40 weeks after the final dose of IMP. Study personnel must confirm the continued use of abstinence is still in accordance with the participant's lifestyle at regular intervals during the study.
Male participants with a partner of childbearing potential must be willing to use a condom when sexually active, until 40 weeks after the last administration of IMP.
An Institutional Review Board (IRB)/Independent Ethics Committee (IEC) approved written Informed Consent form is signed and dated by the participant.
Exclusion criteria
Study participant has any medical or psychiatric condition could jeopardize or would compromise the study participant's ability to participate in this study as determined by the investigator based on protocol-required assessments.
Study participant has a draining fistula count of > 20 at the Baseline Visit.
Study participant has any other active skin disease or condition (eg, bacterial cellulitis, candida intertrigo, extensive condyloma) that may, in the opinion of the investigator, interfere with the assessment of HS.
Study participant has a diagnosis of sarcoidosis, systemic lupus erythematosus, or active inflammatory bowel disease (IBD).
Study participant has a primary immunosuppressive condition, including taking immunosuppressive therapy following an organ transplant or has had a splenectomy.
Female study participant who is breastfeeding, pregnant, or plans to become pregnant during the study or within 40 weeks following the final dose of IMP.
Study participant has an active infection or history of infection(s) as follows:
Opportunistic infections are infections caused by uncommon pathogens (eg, Pneumocystis jirovicii, cryptococcosis), or unusually severe infections caused by common pathogens (eg, cytomegalovirus, herpes zoster).
Study participant has any of the following (for more information, refer to Section 9.2):
Study participant has an acute or chronic hepatitis B virus, hepatitis C virus (HCV), or human immunodeficiency virus (HIV) infection or treponema pallidum antibody (TPPA) positive. Study participants who have evidence of, or tested positive for, hepatitis B or hepatitis C will be excluded.
Study participants with concurrent malignancy are excluded. Study participants with a history of malignancy within the past 5 years prior to the Screening Visit are excluded, EXCEPT if the malignancy was a cutaneous squamous or basal cell carcinoma, or in situ cervical cancer that has been treated and is considered cured.
Study participant has a history of a lymphoproliferative disorder including lymphoma or current signs and symptoms suggestive of lymphoproliferative disease.
Study participant has had major surgery within the 3 months prior to the Baseline Visit, or has planned major surgery after entering the study.
Study participant has any systemic disease (ie, cardiovascular, neurological, renal, liver, metabolic, gastrointestinal, hematological, immunological, etc.) considered by the investigator to be uncontrolled, unstable, or likely to progress to a clinically significant degree during the course of the study.
Study participant has had a myocardial infarction or stroke within the 6 months prior to the Screening Visit.
Study participant has a history of chronic alcohol or drug abuse within 6 months prior to Screening as evaluated by the investigator based on medical history and interview.
Study participant has a history of depression and/or suicidal thoughts or behaviors are considered not suitable for participation in the clinical study by the investigator.
The participant has a known hypersensitivity to any excipients of SCT650C.
Study participants with prior exposure to biologic agents that block IL-12/23 (e.g., ustekinumab), IL-23 (e.g., risankizumab, guselkumab), or IL-17 (e.g., secukinumab) within 3 months prior to the Baseline visit.
Study participants with prior exposure to anti-TNF therapy (e.g., adalimumab, infliximab) for any indication within 2 months prior to the Baseline visit.
Study participants who have had prior exposure to other immunomodulatory biologic therapies, including anti-IL-1 (e.g., anakinra, canakinumab), within 3 months or 5 half-lives, whichever is longer, prior to the Baseline visit.
Previous treatment with any cell-depleting therapies, including but not limited to anti-CD20 (e.g., rituximab) within 12 months prior to the Baseline visit or until B cell count returns to normal level.
Use of traditional medicines or herbal remedies within 28 days prior to the Baseline visit.
Study participants have received non-allowable topical therapies (including topical antibiotics) for the treatment of HS within 14 days prior to the Baseline visit.
Study participants have received systemic non-biologic therapies (e.g. methotrexate (MTX), cyclosporine A, retinoids, apremilast, phototherapy) for the treatment of HS within 28 days prior to the Baseline visit.
For HS and non-HS related pain, participants have received oral concomitant analgesics (including opioids) within 14 days prior to the Baseline visit.
Exception: Participants may continue on non-opioid analgesics provided that the dose and dosing regimen have been stable for at least 14 days preceding the Baseline visit and are expected to remain stable at least until Week 16 visit.
Study participants have received any live vaccine within 8 weeks prior to the first dose of study drug (Baseline), or expect the need for live vaccination during study participation including within 40 weeks after the last dose of study drug administration.
Study participants have been treated with any other investigational drug within 30 days or 5 half-lives of the drug (whichever is longer) prior to the first dose of study drug or is currently enrolled in another clinical study.
Study participant has laboratory abnormalities at Screening, including any of the following:
Study participant has an estimated glomerular filtration rate (GFR) as measured by Chronic Kidney Disease Epidemiology Collaboration <60mL/min/1.73m2 [GFR (male)=(140-age)ⅹWeight/serum creatinineⅹ1.23; GFR (female)=(140-age)ⅹWeight/serum creatinineⅹ1.04].
Study participant has any other laboratory abnormality that, in the investigator's opinion, will prevent the study participant from completing the study or will interfere with the interpretation of the study results.
The participant is a SinoCellTech (SCT) employee or is an employee of third-party organizations involved in the study.
