In this analysis of patients with myeloperoxidase-ANCA-positive AAV, all urinary complement C3 fragment levels were elevated significantly compared with healthy controls (P <.01 for all).

- Mean sustained reductions in C3 of ≥87%, AH50 of ≥76%, Wieslab AP of ≥89% through week 24 - Mean reduction in spot urine protein-to-creatinine ratio (UPCR) of 41% by week 24 PASADENA, ...

Dysregulated complement pathways are linked to progression from iAMD to advanced AMD, including NVAMD and GA. Higher systemic levels of C4, C4b, and a reduction in C3 are associated with increased ...

TSP-1 reduced C3 and C5 cleavage and formation of the membrane attack complex, attenuating complement-mediated injury in AAV models. Complement activation is a relevant driver in the pathomechanisms ...

Iptacopan targets one of the major proteins involved in the enzymes of the alternative pathway of complement, explains Carla Nester, MD, of Stead Family Children's Hospital. In April, in part 1 of ...
