Mechanism of action

Saizen® (somatropin) is a synthetic form of human growth hormone (hGH) produced via recombinant DNA technology. It binds to growth hormone receptors on target tissues, stimulating linear growth, protein synthesis, and lipolysis while affecting carbohydrate and mineral metabolism. The trial appears to be comparing Saizen® efficacy and safety against placebo in a growth hormone-deficient or growth-related indication.
