NCIt definition : A recombinant human leptin analog composed of human leptin with the addition of a
methionine residue at its amino terminus, that may be used for the treatment of leptin
deficiency. Upon administration, metreleptin binds to and activates the human leptin
receptor (ObR). This activates leptin/ObR-mediated signaling pathways. Leptin, a hormone
predominantly secreted by adipose tissue, plays an important role in maintaining energy
homeostasis.;
