This invention relates to the use of S100a8 / a9 and complement 3 inhibitors in the preparation of medicaments for the treatment or prevention of
cachexia, wherein the treatment or prevention of
cachexia involves increasing the
body weight,
lean body mass,
fat mass, and
food intake of cachectic subjects, or preventing
fat loss, slowing the rate of
weight loss, slowing the rate of
fat mass loss, slowing the rate of
lean body mass loss, resisting
anorexia, resisting
muscle weakness, resisting fatigue, resisting
weight loss, and improving abnormal biochemical results. This invention provides a new understanding of the mechanism of
energy balance regulation in
cancer cachexia, focusing on the roles of S100a8 / a9 and C3 in
cancer cachexia. This invention finds that inhibiting S100a8 / a9 and complement 3 can promote fat
recovery and increase
food intake. In particular, it demonstrates that S100a8 / a9 inhibitors can prevent the loss of
body weight, especially
adipose tissue, in cachectic subjects and significantly increase their
food intake.
