GLOBAL COMPLEMENT INHIBITORS MARKET: GROWTH AND TRENDS
Complement system was discovered in the 19th century as a part of immune system, responsible for tissue repair and homeostasis, thereby providing first line of defense against multiple infections. This complete process is in association with a complex and highly regulated assembly of proteins which involve several soluble and surface-bound complement components, including receptors and regulators, which are primarily generated by the liver. These proteins, making the base for complement therapeutics, interact with multiple immune cells and complement the action of antibodies, which are in turn responsible for killing the infectious agents. Additionally, the complement system contributes to maintaining homeostasis in healthy organisms by facilitating the clearance of apoptotic cells and regulating cell survival. However, when complement activation is insufficient, pathogens can proliferate, and the suppression of complement regulators may occur, ultimately leading to disease. Consequently, therapeutics targeting the complement system have been developed to inhibit its activation, which helps reduce tissue inflammation and modulate the adaptive immune response to both foreign and self-antigens.

Driven by encouraging clinical research efforts, new pharmaceutical entrants, broadening of disease focus, and a rising desire to get beyond C5 with some innovative ways, the complement inhibitors market is expected to capture a significant share in the pharmaceutical market with more drug candidates getting approved and marketed over the coming decade.
