Olaratumab Pregnancy Warnings

No animal studies have been conducted with this drug to evaluate its effect on female reproduction and embryofetal development. Animal knockout models link disruption of platelet-derived growth factor receptor alpha (PDGFR-alpha) signaling to adverse effects on embryofetal development. Administration of an anti-murine PDGFR-alpha antibody to pregnant mice during organogenesis at exposures less than at the maximum recommended human dose caused malformations and skeletal variations. There are no controlled data in human pregnancy.

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. Pregnancy categories A, B, C, D and X are being phased out.

This drug should be used during pregnancy only if the benefit outweighs the risk.
