IGFBP2 is a protein that carries out the actions of leptin, a hormone that regulates fat and glucose metabolism. The ability of IGFBP2 to do this resides in a small peptide sequence within its structure. AZP-3404 is a stabilized peptide analog of this sequence and is the first drug candidate to reproduce and utilize the unique biology of IGFBP2.1,2,3
We are currently exploring target indications for AZP-3404.
