Biodistribution & persistence
No placental transfer in rats: radioactivity absent from fetal blood, tissues and amniotic fluid
“While radioactivity was detected in the amniotic sac and placenta of pregnant rats, it was not detected in fetal blood, fetal tissues, or amniotic fluid, indicating that orforglipron did not cross the placental barrier in rats.”

Modality-specific risk
On-target developmental and carcinogenicity risk cannot be differentiated from peptide GLP-1 receptor agonists
“Therefore, the on-target developmental and carcinogenicity risk for orforglipron cannot be differentiated from peptide-based GLP-1 receptor agonists.”
