Elagolix Pregnancy Warnings

Pregnant rats and rabbits receiving this drug during the period of organogenesis experienced post implantation loses at 20 times the maximum recommended human dose (MRHD). In rabbits, spontaneous abortion and total litter loss occurred at 7 and 12 times the MRHD. Structural abnormalities were not reported at doses up to 40 (rat) and 12 (rabbit) times the MRHD. In human clinical trials, 49 pregnancies were reported; these pregnancies occurred during therapy or within 30 days of stopping. Two cases of congenital malformation were reported; one case of infant cleft palate (exposure occurred during the first 30 days of pregnancy) and 1 case of infant tracheoesophageal fistula (exposure occurred during the first 15 days of pregnancy). In both cases, the dose was 150 mg/day. Five cases of spontaneous abortion occurred in those receiving this drug compared to 5 cases among 20 pregnancies in women (n=1100) receiving placebo. 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.
