Biodistribution & persistence
Prolonged retention in eye (t1/2 182.5 h) and lacrimal gland (t1/2 135.7 h)
“By 24/72 hours post dose, radioactivity was either close to or below the limit of quantification in the majority of the tissues, except the eye (T1/2 182.5 hours) and lacrimal gland (T1/2 135.7 hours).”

Modality-specific risk
Ocular toxicity (corneal atrophy) translating to clinical dry eye and keratitis
“Similar to animals, in patients treated with erdafitinib, dry eye and keratitis (inflammation of cornea) were reported, although the corneal opacities and atrophy found in animals were not noted in patients (possibly due to intervention/use of lubricating drops).”
