“Despite its abundance in plasma relative to AGP, albumin contributed to <4% of the overall binding of erdafitinib (1.8% in patients; 4.0% in healthy participants).”
“Linear binding of erdafitinib to AGP and albumin was observed, with >1000‐fold higher binding constant for AGP than albumin (17.6 vs 0.017 µM‐1).”
