Modality-specific risk
Ocular toxicity: lacrimal gland atrophy and optic nerve hemorrhage in rats at ≥0.2x human AUC
“In rats, treatment with ≥10 mg/kg sevabertinib (≥0.2 times the human exposure at the recommended dose of 20 mg BID based on AUC) resulted in slight atrophy of the lacrimal gland and minimal optic nerve hemorrhage.”
