somatropin erdafitinib
Applies to: Nutropin (somatropin) and erdafitinib
Monitor
Coadministration with human growth hormone (hGH) receptor agonists may alter the clearance and plasma concentrations of medicinal products that are metabolized by CYP450 isoenzymes. The mechanism of this interaction may be mediated via the effects of hGH receptor agonists on expression of different CYP450 isoenzymes. The labeling of some hGH receptor agonists specify that this interaction may be the most significant for substrates of CYP450 3A4 and/or 1A2 and indicate that their clearance may be increased. However, clinical data are limited, and clinical significance is unknown. In a study of 11 growth hormone (GH)-deficient adults randomized to GH or placebo for 6 months followed by 3 months of GH for all subjects, antipyrine clearance, a non-specific marker of hepatic CYP450 activity, increased in all subjects who received GH treatment compared to placebo. In vitro studies have indicated that GH enhanced CYP450 3A4 gene expression; however, other studies have suggested that when administered in a pulsatile fashion, CYP450 3A4 activity is reduced. A study in healthy elderly men did not reveal any effects on CYP450 3A4 or 2D6 but did demonstrate induction of 1A2 and inhibition of 2C19. Given that studies have varied in the type of growth hormone used, dosing regimens, ages and sexes of the patients and/or cell lines utilized, it is difficult to predict how coadministration may affect the CYP450 substrate.
Management
Careful monitoring is advised when drugs that are metabolized by CYP450 isoenzymes are used in combination with hGH receptor agonists. As this interaction's clinical significance is unknown, the label of the specific hGH receptor agonist and CYP450 substrate(s) being coadministered should be consulted for more specific guidance.

Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
erdafitinib Food/Lifestyle
Applies to: erdafitinib
Generally avoid
Grapefruit or grapefruit juice may increase the plasma concentrations of erdafitinib. The proposed mechanism for the interaction is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Inhibition of hepatic CYP450 3A4 may also contribute. The interaction has not been studied with grapefruit juice but has been reported for other CYP450 3A4 inhibitors. When coadministered with itraconazole, a strong CYP450 3A4 inhibitor, erdafitinib mean ratios for the peak plasma concentration (Cmax) and systemic exposure (AUC) were 105% and 134%, respectively, relative to erdafitinib alone. Increased exposure of erdafitinib may heighten the risk of hyperphosphatemia and gastrointestinal, dermatologic, and ocular toxicities. In general, the effects of grapefruit products are concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition.
Management
Until further information is available, it may be advisable for patients to limit or avoid consumption of grapefruit, grapefruit juice, or Seville oranges during treatment with erdafitinib.
