Systemic Lupus Erythematosus
Conditions
Brief summary
This is a first exploration of GLPG3970 in subjects with active systemic lupus erythematosus (SLE) to evaluate the effect on disease biomarkers and to determine its pharmacokinetics (PK) profile, safety and tolerability, and pharmacodynamics (PD) biomarkers related to the investigational product (IP) mechanism of action and the pathophysiology of SLE.
Interventions
GLPG3970 for oral administration
Placebo for oral administration

Inclusion criteria
* SLE diagnosis defined by American College of Rheumatology (ACR) 1997 criteria ≥4 * Active arthritis in \>=4 active joints (according to 28 joint count) and/or cutaneous lupus erythematosus disease area and severity index (CLASI) score \>=6. * Anti-dsDNA antibodies \>15 IU/mL. * Stable standard-of-care (SoC) therapy (defined as no change in prescription for at least 2 weeks prior to first IP dosing) consisting of the following permitted SoC medications: * Corticosteroids \<=20 mg/day (prednisone or equivalent) for at least 2 weeks prior to first IP dosing; AND/OR * Non-steroidal anti-inflammatory drug (NSAIDs); AND/OR * One single antimalarial at a stable dose (hydroxychloroquine \<=5 mg/ kg/day, quinacrine 100 mg/day, or chloroquine 2.3 mg/kg/day) for at least 8 weeks prior to first IP dosing; AND/OR * One single immunosuppressant at a stable dose (azathioprine (AZA) \<=2 mg/kg/day, methotrexate (MTX) \<=20 mg/week, or mycophenolate mofetil (MMF) \<=2 g/day) for at least 8 weeks prior to first IP dosing. * estimated glomerular filtration rate (eGFR) \>=60 mL/min (according to Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI)) This list only contains the key inclusion criteria.
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in biomarkers associated with disease anti-dsDNA | Between Day 1 and 104 | To characterize the PD of GLPG3970 compared to placebo in adult subjects with active SLE |
| Change in biomarkers associated with disease complement component 3 (C3), and complement component 4 (C4) | Between Day 1 and 104 | To characterize the PD of GLPG3970 compared to placebo in adult subjects with active SLE |
| Number, incidence, and severity of treatment-emergent adverse events (TEAEs) | From screening through study completion, an average of 5 months | To evaluate the safety and tolerability of GLPG3970 compared to placebo in adult subjects with active SLE |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Observed GLPG3970 plasma trough concentrations (Ctrough) | Between Day 1 and 87 | To characterize the PK of GLPG3970 in adult subjects with active SLE |
