描述
ARX201 (PEG-ahGH) is a recombinant form of human growth hormone that has been modified using Ambrx’s patented ReCODE™ technology to achieve precise spatial positioning of the site of polyethylene glycol (PEG) attachment to human growth hormone, by biosynthetic incorporation of a chemically unique amino acid (ahGH). ARX201 has improved pharmacological properties, which should allow less frequent administration than the daily dosing regimen of currently available growth hormones.
