First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 2 times

Summary

This registry aimed to track pregnancy outcomes in women who were exposed to elagolix (brand names Orilissa and Oriahnn) for endometriosis or uterine fibroids. The study planned to enroll 584 pregnant women, half with elagolix exposure and half without, and follow them through pregnancy and one year after delivery. However, the study was terminated early with only 173 participants enrolled, so results may be limited.

What this could lead to

If successful, this registry could provide important safety information about pregnancy outcomes after elagolix use, helping doctors and patients make informed decisions.

What could go wrong

The study was terminated early with only 173 enrolled out of a planned 584, which may limit the reliability and generalizability of the results. As an observational registry, it cannot prove cause and effect.
