AbPropertiesClinical trials*ResultsReferences
Dapirolizumab pegol (CDP7657)Anti-CD40L FabPhase 2 trial for SLE

Improved clinical outcomes of the disease

Well-tolerated

Did not reach the primary endpoint of dose-response in phase 2b

[114116]
VIB4920CD40L binding protein composed of 2 Tn3 proteins fused to serum albuminPhase 1b for RA

Decreased disease activity

Safe without serious adverse effects

[119, 120]
Iscalimab (CFZ533)Fully human antagonistic anti-CD40 monoclonal IgG1 Abs

Phase 2 for:

Kidney transplant-SS

Safer than tacrolimus in regards to nephrotoxicity and infectious complications but less efficacious in preventing transplant rejection

Efficacious for SS

Good add-on to methotrexate

Improved clinical outcomes

Reduced RF auto-Ab titers

This table presents information on the different molecules made to inhibit the CD40/CD40L interaction. Inhibiting this interaction greatly affects the immune response and thus it has been used in clinical trials against autoimmune diseases and transplant rejection. *: this list is not comprehensive. SS: Sjogren’s syndrome; RF: rheumatoid factor
