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 (<.05). While rhGH had little or no effect on CYP1A2 or CYP2C19 mRNA but increased CYP3A4 mRNA twofold, TV-1106 had little or no effect on cytochrome P450 (CYP) mRNAs in hepatocytes. Although the plasma from rhGH-treated blood lowered CYP1A2 activity, the TV-1106 plasma had no effect on CYP activities. The CYP1A2 activity was lower in the rhGH- then in the TV-1106-plasma treated hepatocytes (<.05). The results indicated that fusing GH with albumin made TV-1106 an unlikely participant of CYP1A2, CYP2C19 or CYP3A4-facilitated, direct or cytokine-driven DDI.
有些生物制剂可以调节细胞因子,从而导致药物代谢酶的表达发生变化,并引起药物相互作用(DDI)。研究了 TV-1106(一种与白蛋白融合的生长激素(GH))的 DDI 潜力。在这项研究中,用人重组生长激素(rhGH)或 TV-1106 处理人血液,然后分离血浆并将其应用于人肝细胞。rhGH 处理血液会增加多种细胞因子,而 TV-1106 处理血液对测试的 9 种细胞因子均无影响。rhGH 处理后的血浆中白细胞介素(IL)-6 浓度高于 TV-1106 处理后的血浆(<0.05)。rhGH 对 CYP1A2 或 CYP2C19 mRNA 几乎没有影响,但使 CYP3A4 mRNA 增加两倍,而 TV-1106 对肝细胞中的细胞色素 P450(CYP)mRNA 几乎没有影响。虽然 rhGH 处理后的血液血浆降低了 CYP1A2 活性,但 TV-1106 血浆对 CYP 活性没有影响。rhGH 处理后的血浆中 CYP1A2 活性低于 TV-1106 处理后的血浆(<0.05)。结果表明,将 GH 与白蛋白融合使 TV-1106 不太可能参与 CYP1A2、CYP2C19 或 CYP3A4 介导的直接或细胞因子驱动的 DDI。
