About this study
The purpose of this study is to evaluate the ability of dapirolizumab pegol (DZP) as an add-on treatment to standard of care (SOC) medication to achieve clinically relevant long term improvement of moderate to severe disease activity.
Sponsor: UCB Biopharma SRL
You may qualify if…
- ✓ Study participant must be ≥16 years of age, (≥18 years of age for China), unless restricted by local regulation, at the time of signing the Informed Consent form (ICF)
- ✓ Study participants who have moderate to severe disease activity due to either persisting active systemic lupus erythematosus (SLE) or due to an acute worsening of SLE in the scope of frequent relapsing-remitting SLE despite stable standard of care(SOC) medication defined as:

- ✓ 1. Anti-Smith (anti-Sm) antibodies (central laboratory or source verifiable history)
- ✓ 2. Anti-Sjögren's syndrome antibody A (Anti-SSA) (Ro)/Anti-Sjögren's syndrome antibody B (anti-SSB) (La) autoantibodies (central laboratory)
- ✓ 3. Historical evidence for anti-dsDNA antibodies
- ✓ 4. Anti-ribonucleoprotein (RNP) autoantibodies (central laboratory) d. Moderately to severely active defined as:
- ✓ British Isles Lupus Assessment Group Disease Activity Index 2004 (BILAG 2004) Grade B in ≥2 organ systems and/or a BILAG 2004 Grade A in ≥1 organ systems at Screening and Baseline Visit AND
