Gefurulimab can block the activation of the terminal complement pathway and reduce inflammatory damage. Gefurulimab can effectively reduce the formation of membrane attack complex (MAC) and has good pharmacokinetic properties. Gefurulimab can be used to study kidney and autoimmune diseases related to abnormal activation of the complement system, such as IgA nephropathy, lupus nephritis, and myasthenia gravis.

Vobarilizumab (ALX-0061) is a humanized bispecific anti-IL-6R and anti-human serum albumin (ALB) monoclonal antibody (mAb) (K_d: 0.19 pM). Vobarilizumab consists of an anti-IL-6R domain and an anti-human serum albumin domain. Vobarilizumab can be used in the research of inflammatory autoimmune diseases, such as rheumatoid arthritis.
