Clinical Trials

Numerous clinical trials spanning Early Phase 1 through Phase 3 evaluate the therapeutic application of topical delgocitinib across various dermatological and inflammatory conditions, including chronic hand eczema, atopic dermatitis, palmoplantar pustulosis, mycosis fungoides, frontal fibrosing alopecia, and discoid lupus erythematosus. Sponsored by industry leaders such as LEO Pharma alongside academic institutions including Aarhus University Hospital and the Icahn School of Medicine at Mount Sinai, these studies represent recruitment statuses ranging from completed and actively recruiting to upcoming and terminated.

Compliance for Clinical Use

Mechanism and Biochemical Profile

Delgocitinib is a pan-Janus kinase inhibitor that potently binds JAK1, JAK2, JAK3, and Tyk2, thereby blocking intracellular STAT phosphorylation and preventing downstream inflammatory cytokine signaling cascades. This inhibition suppresses hyperactive local immune responses, mitigating tissue inflammation and providing clinical relevance in dermatological conditions such as chronic hand eczema and atopic dermatitis.

Appendix RUO and cGMP Quality Standards

Quality Dimension RUO (Research Use Only) cGMP (Current Good Manufacturing Practice)
Clinical Applicability Prohibited in human clinical trials or medical diagnostics. Mandatory for human clinical trials (Phase I–III) and therapies.
Regulatory Status Non-regulated grade; exempt from drug manufacturing laws. Legally enforced by health authorities (e.g., FDA, EMA, NMPA).
Facility Environment Unclassified analytical or research laboratories. Validated Cleanrooms (ISO Class 5–8) with continuous monitoring.
Quality Control Basic purity and activity testing. Rigorous safety release testing (Sterility, Endotoxin, Mycoplasma).
Process Validation Basic equipment calibration; no process validation required. Full qualification (IQ/OQ/PQ) and complete batch records.
Quality Assurance Vendor self-declared without required formal QMS. Mandatory QA/QC unit, Change Control, CAPA, and vendor audits.
Regulatory Impact High risk of IND rejection if used as a critical raw material. Required for IND/NDA filings, supported by Drug Master Files (DMF).
