Mobocertinib Pregnancy and Breastfeeding Warnings

Mobocertinib is also known as: Exkivity

Mobocertinib Pregnancy Warnings

Animal studies have revealed evidence of embryolethality, fetotoxicity, and maternal toxicity. Oral administration to pregnant rats during organogenesis resulted in embryolethality due to postimplantation loss (embryofetal death), decreased fetal weights, and maternal toxicity (reduced body weight gain and food consumption) at 10 mg/kg/day (about 1.7 times the human exposure based on AUC at 160 mg once daily). There are no controlled data in human pregnancy.

Based on animal studies, this drug may impair fertility in males and females of reproductive potential.

US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy.
