Avdoralimab (IPH5401) is a therapeutic antibody that specifically binds and blocks C5a receptors (C5aR1) expressed on subsets of myeloid-derived suppressor cells (MDSC) and neutrophils. Targeting C5a/C5aR1 has been demonstrated scientifically and through positive clinical trials in some complement-driven inflammatory diseases.

Avdoralimab is being investigated in inflammation.

The Company is pursuing a Phase 2 investigator-sponsored trial in bullous pemphigoid (BP) where the C5aR1 pathway has been shown to be strongly involved in the physiopathology of the disease.
