Cabiralizumab (FPA 008) is an anti-CSF1R monoclonal antibody (MAb). Cabiralizumab enhances T cell infiltration and antitumor T cell immune responses. Cabiralizumab inhibits the activation of osteoclasts and blocks bone destruction, and can be used in the research of rheumatoid arthritis (RA). Cabiralizumab can combine with Nivolumab (HY-P9903) for lung cancer research.

Lampalizumab (RG 7417) is a humanised monoclonal antibody targeting complement Factor D in the alternative complement pathway. Lampalizumab binds an exosite and sterically blocks Factor B access to the active site. Lampalizumab can be used for age-related macular degeneration (AMD) research.

Avdoralimab (IPH 5401) is a fully human IgGκ monoclonal antibody that targets the complement C5a receptor 1 (C5aR1) that prevents its binding to C5a. Avdoralimab can be used for complement-driven inflammatory diseases and solid tumours research.

Vilobelimab (CaCP-29, IFX-1) is a monoclonal anti-C5a antibody to the allergen C5a, a pro-inflammatory complement division product that plays a central role in mediating organ dysfunction. Vilobelimab acts as a C5a inhibitor, inhibiting neutrophil activation, chemotaxis, and reducing inflammatory signalling, and may be used in studies related to sepsis, COVID-19, etc.

Ravulizumab (ALXN1210) is a humanized monoclonal antibody that specifically binds with high affinity to the human complement protein C5. Ravulizumab can be used for the research of paroxysmal nocturnal hemoglobinuria, atypical hemolytic uremic syndrome, and myasthenia gravis.

Pozelimab (REGN3918) is a fully human IgG4 anti-C5 monoclonal antibody. Pozelimab binds to C5 and C5 variants with high affinity and blocks complement-mediated hemolysis. Pozelimab can be used for the research of complement-mediated diseases.

Crovalimab (SKY59; RO7112689) is a novel humanized antibody against C5 in a pH-dependent manner with KDs of 15.2 nM and 16.8 μM at pH 7.4 and 5.8, respectively. Crovalimab binds human FcRn with great affinity (KD: 17 μM at pH 6.0). Crovalimab can block cleavage of C5 by the C5 convertase and inhibite the activity of a C5 variant (p.Arg885His). Crovalimab inhibits C5b-9 formation significantly in all three complement pathways, the classical pathway (CP), lectin pathway (LP), and alternative pathway (AP). Crovalimab has the potential for paroxysmal nocturnal hemoglobinuria (PNH) and complement-mediated diseases research.

Empasiprubar (ARGX-117) is a humanized inhibitory monoclonal antibody targeting complement C2. Empasiprubar binds to the Sushi-2 domain of C2, preventing the formation of C3 pre convertase and inhibiting the activation of classical and lectin pathways upstream of C3 activation. Empasiprubar can prevent complement mediated autoimmune hemolytic anemia and antibody mediated organ transplant rejection. Empasiprubar can prevent neuroglial lymphoconjunctival injury in GM1 antibody mediated mouse models.
