Abstract
Some biologics can modulate cytokines that may lead to changes in expression of drugmetabolizing
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
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 (P < .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.
