Teratogenic Effect of Radotinib: Case Report

Abstract

Background: Simultaneous presentation of pregnancy and chronic myeloid leukemia (CML) is rare. Tyrosine kinase inhibitors (TKIs) are rarely used in pregnancy. There is almost no information on the effect of recently developed TKIs on the fetus. Case Report: A 22-year-old woman became pregnant while using radotinib, a novel TKI for CML. She was concerned about the possible teratogenic effect of radotinib; hence the first pregnancy was terminated. The patient underwent full-term delivery at the second pregnancy. The infant had facial deformity and congenital laryngomalacia. Conclusion: We witnessed structural abnormality when the patient used radotinib during the first trimester of pregnancy. When radotinib is prescribed for women of childbearing age, thorough education about contraception is necessary.
