Additional Relevant Details AstraZeneca has built a growing scientific presence in oncology, and in cardiovascular, renal and metabolism, and respiratory diseases, with a focus on organ protection. AstraZeneca has developed a broad range of technologies, initially focused on small molecules and biologics and with a growing focus in precision medicine, genomics, oligonucleotides and epigenetics. More recently, AstraZeneca has increased its efforts in immunology research and the development of medicines for immune-mediated diseases.
Alexion has pioneered complement inhibition for a broad spectrum of immune-mediated rare diseases caused by uncontrolled activation of the complement system, a vital part of the immune system. Alexion's franchise includes Soliris (eculizumab), a first-in-class anti-complement component 5 (C5) monoclonal antibody. The medicine is approved in many countries for the treatment of patients with paroxysmal nocturnal haemoglobinuria (PNH), atypical haemolytic uremic syndrome, generalized myasthenia gravis and neuromyelitis optica spectrum disorder. More recently, Alexion launched Ultomiris (ravulizumab), a second-generation C5 monoclonal antibody with a more convenient dosing regimen.
Alexion's immunology expertise extends to other targets in the complement cascade beyond C5 as well as additional modalities, with its deep pipeline including Factor D small-molecule inhibitors of the alternative pathway of the complement system, an antibody blocking neonatal Fc receptor (FcRn)-mediated recycling, and a bi-specific mini-body targeting C5, among others. The FcRn extends the half-life and hence the availability of pathogenic immunoglobulin G (IgG) antibodies.
AstraZeneca, with Alexion's R&D team, will work to build on Alexion's pipeline of 11 molecules across more than 20 clinical-development programmes across the spectrum of indications, in rare diseases and beyond.
