Growth Horm IGF Res

Administration study of somapacitan, a long-acting growth hormone derivative, in horse for doping control purpose. Shimizu Y, Sugai-Bannai M, Tanabe H, Saito K, Ito H, Tokushige H, Kamiya K, Hirano-Kodaira M, Yamada M, Leung GN.Somapacitan is the second generation of recombinant human growth hormone (rhGH) medication that retains the pharmacological effects of rhGH but exhibits a longer duration of action due to its reversible albumin-binding in the body. In general, the use of all recombinant growth hormone (rGH) analogues is banned by the human and animal sports regulatory authorities due to their anabolic and lipolytic effects. However, little is known about the elimination kinetics and biological effects of the newly introduced long-acting rhGH, somapacitan, in horses. This paper describes the administration stud...
Identification and differentiation of somapacitan, a long-acting growth hormone derivative, and recombinant human growth hormone in equine plasma by LC-HRMS for doping control purpose. Shimizu Y, Sugai-Bannai M, Saito K, Hirano-Kodaira M, Leung GN.Somapacitan, a long-acting growth hormone derivative, and recombinant human growth hormone (rhGH) are protein-based drugs generally used to treat growth disorders and GH deficiency in humans. Due to their potential to enhance the horse performance, the use of these drugs is prohibited at-all-times by the International Federation of Horseracing Authorities for horseracing and the Fédération Equestre Internationale for equestrian sports. In this study, we developed a test method for the identification and differentiation of somapacitan and rhGH in equine plasma by using liquid chromatography h...
