2. unexposed to any DMT during pregnancy, defined as having never received DMT therapy; discontinued treatment with DRF at least 1 day before 2 weeks after the first day of their LMP (i.e., conception date); or discontinued a non Registry-specified MS DMT more than 5 times its half-life prior to 2 weeks after the first day of their LMP (i.e., conception date)

Voxsanity reformats data from public registries into this layout. It does not edit, interpret or add to what the registry published.

Not medical advice.

Individual trial records are refreshed on a rolling basis rather than all at once, so a record may be up to several weeks old. Each trial page and trial card shows the date its own record was last synced. Where a record has lagged, its status, sites and enrolment can differ from the current registry state in either direction, so check the registry link on the trial page before acting on them.
