摘要

Some biologics can modulate cytokines that may lead to changes in expression of drug‐metabolizing enzymes and cause drug‐drug interactions (DDI). DDI potential of TV‐1106—an albumin‐fused growth hormone (GH)—was investigated. In this study, human blood was exposed to recombinant human growth hormone (rhGH) or TV‐1106, followed by isolation of the plasma and its application to human hepatocytes. While the treatment of blood with rhGH increased multiple cytokines, treatment of blood with TV‐1106 had no effect on any of the nine cytokines tested. The interleukin (IL)‐6 concentration was higher in the rhGH then in the TV‐1106‐treated plasma (P < .05). While rhGH had little or no effect on CYP1A2 or CYP2C19 mRNA but increased CYP3A4 style="fixed-case">mRNA twofold, style="fixed-case">TV‐1106 had little or no effect on cytochrome P450 ( style="fixed-case">CYP) style="fixed-case">mRNAs in hepatocytes. Although the plasma from rh style="fixed-case">GH‐treated blood lowered style="fixed-case">CYP1A2 activity, the style="fixed-case">TV‐1106 plasma had no effect on style="fixed-case">CYP activities. The style="fixed-case">CYP1A2 activity was lower in the rh style="fixed-case">GH‐ then in the style="fixed-case">TV‐1106‐plasma treated hepatocytes (P < .05). The results indicated that fusing style="fixed-case">GH with albumin made style="fixed-case">TV‐1106 an unlikely participant of style="fixed-case">CYP1A2, style="fixed-case">CYP2C19 or style="fixed-case">CYP3A4‐facilitated, direct or cytokine‐driven DDI.
