Participants whose disease activity is deemed unsuitable for study enrollment by the investigator (including but not limited to situations where 4 weeks of placebo-only treatment may lead to unacceptable disease progression).\n2. Comorbidities of other skin diseases that may interfere with study assessments, such as psoriasis, severe acne, rosacea, atopic dermatitis, etc., which would confound the observation of seborrheic dermatitis lesions.\n3. Administration of systemic glucocorticoids, systemic retinoids, immunosuppressants, oral/intravenous antifungals, phototherapy, PDE-4 inhibitors, or JAK inhibitors within 4 weeks; topical glucocorticoids, calcineurin inhibitors, PDE-4 inhibitors, antifungals, retinoids, keratolytics, selenium/tar-containing preparations on the study area within 2 weeks; any biologic agents within 6 months; or potent CYP3A4 inhibitors/inducers within 4 weeks.\n4.

A history of known severe hypersensitivity or severe adverse reactions to ZYG24002 or its excipients.\n6. Comorbidities of other skin diseases that may increase the systemic absorption of ZYG24002, such as Netherton syndrome or erythroderma.\n7. Current use of immunosuppressants or diagnosis of immune deficiency.\n8. A history of malignancy within 5 years prior to screening or at screening.\n9. Poorly controlled chronic diseases, including but not limited to endocrine disorders (e.g., diabetes mellitus with significantly elevated fasting blood glucose and obvious clinical symptoms, hyperthyroidism); a history of severe cardiovascular and cerebrovascular diseases (e.g., myocardial infarction, stroke); active peptic ulcers or chronic inflammatory bowel disease, etc.\n10. Abnormal liver function: ALT or AST \\> 2 × upper limit of normal (ULN), or total bilirubin \\> 1.5 × ULN at screening; abnormal renal function: serum creatinine \\> 1.5 × ULN; or other clinically significant abnormal laboratory findings that are deemed unsuitable for enrollment by the investigator.\n11. Human immunodeficiency virus (HIV) infection; active hepatitis C virus (HCV) infection (anti-HCV positive); active hepatitis B virus (HBV) infection (HBV-DNA \\> 2000 IU/mL or 10⁴ CPs/mL); or positive treponema pallidum antibody with evidence of active infection.\n12. Diagnosis of psychiatric or neurological disorders that may affect compliance or increase study-related risks.\n13. Pregnancy, lactation, or planned pregnancy; female subjects of childbearing potential who have not initiated reliable contraceptive measures at least 30 days prior to the first dose and who cannot commit to maintaining such measures for 3 months after the last dose.\n14. Diagnosis of alcohol or addictive substance dependence within the past 12 months, or other conditions that the investigator believes may compromise study compliance.\n15. Any other conditions that the investigator deems may interfere with study results or pose an unacceptable safety risk to the participant."}, 'identificationModule': {'nctId': 'NCT07404033', 'briefTitle': 'ZYG24002 Lotion to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy in Adult Patients With Mild to Moderate Seborrheic Dermatitis', 'organization': {'class': 'INDUSTRY', 'fullName': 'Sinomune Pharmaceutical Co., Ltd'}, 'officialTitle': 'A Multicenter, Randomized, Double-Blind, Placebo-Controlled Phase Ⅰb Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of Different Concentrations of ZYG24002 Lotion in Adult Patients With Mild to Moderate Seborrheic Dermatitis', 'orgStudyIdInfo': {'id': 'ZYG-24002-Ⅰ-01-2025-02'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'ZYG24002 0.5%， BID', 'description': 'Participants apply 0.5% concentration or placebo ZYG24002 Lotion twice daily (BID) for a consecutive period of 28 days.', 'interventionNames': ['Drug: ZYG24002 0.5%', 'Drug: ZYG24002 Placebo']}, {'type': 'EXPERIMENTAL', 'label': 'ZYG24002 0.75% ,BID', 'description': 'Participants apply 0.75% concentration or placebo ZYG24002 Lotion twice daily (BID) for a consecutive period of 28 days.', 'interventionNames': ['Drug: ZYG24002 0.75%', 'Drug: ZYG24002 Placebo']}, {'type': 'EXPERIMENTAL', 'label': 'ZYG24002 1%, BID', 'description': 'Participants apply 1% concentration or placebo ZYG24002 Lotion twice daily (BID) for a consecutive period of 28 days.', 'interventionNames': ['Drug: ZYG24002 1%', 'Drug: ZYG24002 Placebo']}, {'type': 'EXPERIMENTAL', 'label': 'ZYG24002 1%, QD', 'description': 'Participants apply 1% concentration or placebo ZYG24002 Lotion once daily (QD) for a consecutive period of 28 days.', 'interventionNames': ['Drug: ZYG24002 1%', 'Drug: ZYG24002 Placebo']}], 'interventions': [{'name': 'ZYG24002 0.5%', 'type': 'DRUG', 'description': '0.5% concentration of ZYG24002', 'armGroupLabels': ['ZYG24002 0.5%， BID']}, {'name': 'ZYG24002 0.75%', 'type': 'DRUG', 'description': '0.75% concentration of ZYG24002', 'armGroupLabels': ['ZYG24002 0.75% ,BID']}, {'name': 'ZYG24002 1%', 'type': 'DRUG', 'description': '1% concentration of ZYG24002', 'armGroupLabels': ['ZYG24002 1%, BID', 'ZYG24002 1%, QD']}, {'name': 'ZYG24002 Placebo', 'type': 'DRUG', 'description': '0% concentration of ZYG24002', 'armGroupLabels': ['ZYG24002 0.5%， BID', 'ZYG24002 0.75% ,BID', 'ZYG24002 1%, BID', 'ZYG24002 1%, QD']}]}, 'contactsLocationsModule': {'locations': [{'zip': '215000', 'city': 'Suzhou', 'state': 'Jiangsu', 'country': 'China', 'contacts': [{'name': 'Jun Gu, Doctor', 'role': 'CONTACT', 'email': 'gujun79@163.com', 'phone': '+86-18930939371'}], 'facility': 'Suzhou Municipal Hospital', 'geoPoint': {'lat': 31.30408, 'lon': 120.59538}}], 'centralContacts': [{'name': 'Yaheng Wang', 'role': 'CONTACT', 'email': 'wangyaheng@sinomune.com', 'phone': '+86-15312798046'}], 'overallOfficials': [{'name': 'Jun Gu, MD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'Suzhou Municipal Hospital'}]}, 'ipdSharingStatementModule': {'ipdSharing': 'NO'}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Sinomune Pharmaceutical Co., Ltd', 'class': 'INDUSTRY'}, 'responsibleParty': {'type': 'SPONSOR'}}}}
