About this study

Official title: The Ubrelvy and Qulipta Pregnancy Exposure Registry EMPRESS: An Observational, Prospective Study to Assess the Safety of Ubrelvy (Ubrogepant) and Qulipta (Atogepant) During Pregnancy

Migraine is a common neurological disorder typically characterized by attacks of throbbing or pulsating headache on one side of the head of moderate to severe pain intensity. The purpose of this study is to evaluate fetal, maternal, and infant outcomes through 12 months of age among women exposed to Ubrelvy or Qulipta during pregnancy, as well as in 2 comparator groups.

Ubrelvy (ubrogepant) and Qulipta (atogepant) are approved drugs for the acute treatment of migraine in adults. Approximately 628 pregnant women with migraine exposed to Ubrelvy, 628 pregnant women with migraine exposed to Qulipta and 628 pregnant women with migraine in comparator group will be enrolled in this study in the United States.

Participants enrolled in the Ubrelvy-exposed group and Qulipta-exposed group will receive Ubrelvy and Qulipta respectively as prescribed by their physician.

Study groups in NCT05158894
Study groupRoleWhat they receive
Ubrelvy-Exposed Women With MigrainePregnant women with migraine who took at least 1 dose of Ubrelvy, the exposure of interest, at any time during pregnancy as part of routine care.
Qulipta-Exposed Women With MigrainePregnant women with migraine who took at least 1 dose of Qulipta, the exposure of interest, at any time during pregnancy as part of routine care.
Ubrelvy/Qulipta-Unexposed Women With MigrainePregnant women with migraine who have never taken Ubrelvy and/or Qulipta, OR discontinued Ubrelvy 2 days prior or Qulipta 5 days prior to conception.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Major Congenital Malformations (MCMs)

    An MCM is defined as any major structural or chromosomal defect in live born infants, stillbirths/fetal losses of any gestational age.

    Measured: Up through the first 12 months of life

Secondary outcomes (11)
  1. Percentage of Pregnant Participants Experiencing Spontaneous Abortion

    Recognized spontaneous abortion (SAB): loss of an embryo/fetus due to natural causes prior to 20 weeks of gestation.

    Measured: Up through the first 12 months of life

  2. Percentage of Pregnant Participants Experiencing Stillbirth

    A fetal death occurring at 20 gestation weeks or greater, or if gestational age is unknown, a fetus weighing 350 g or more.

    Measured: Up through the first 12 months of life

  3. Percentage of Pregnant Participants With Elective Termination

    Elective termination is voluntary interruption of pregnancy, including pregnancy termination that occurs electively, to preserve maternal health, or due to abnormalities.

    Measured: Up through the first 12 months of life

  4. Percentage of Pregnant Participants Experiencing Preeclampsia

    Preeclampsia is the presence of hypertension on 2 occasions at least 4 hours apart after 20 weeks gestation (in a woman with a previously normal blood pressure) and proteinuria, or new-onset hypertension accompanied by thrombocytopenia, renal insufficiency, impaired liver function, pulmonary edema, or cerebral or visual symptoms.

    Measured: Up through the first 12 months of life

  5. Percentage of Pregnant Participants Experiencing Eclampsia

    Eclampsia is defined as new-onset seizures (tonic-clonic, focal, or multifocal) in the absence of other causative conditions such as epilepsy, cerebral arterial ischemia and infarction, intracranial hemorrhage, or drug use.

    Measured: Up through the first 12 months of life

  6. Percentage of Pregnant Participants Experiencing Gestational Hypertension

    Gestational hypertension is defined as high blood pressure (Elevated: systolic between 120-129 mm Hg and diastolic less than 80 mm Hg; Stage 1 hypertension: systolic between 130-139 mm Hg or diastolic between 80-89 mm Hg; Stage 2 hypertension: systolic at least 140 mm Hg or diastolic at least 90 mm Hg) associated with pregnancy.

    Measured: Up through the first 12 months of life

  7. Percentage of Pregnant Participants Experiencing Gestational Diabetes

    Gestational diabetes is generally characterized by the development of carbohydrate intolerance with first onset or first recognition during pregnancy; a record of an oral glucose tolerance test during pregnancy will also be accepted for data collection, where available.

    Measured: Up through the first 12 months of life

  8. Percentage of Infants Experiencing Preterm Birth

    Preterm birth is defined as an infant born at gestational age <37 weeks.

    Measured: Up through the first 12 months of life

  9. Percentage of Infants Experiencing Small for Gestational Age (SGA) Birth

    SGA at birth based on health care provider (HCP) report, typically defined as birthweight <=10th percentile for sex and gestational age.

    Measured: Up through the first 12 months of life

  10. Percentage of Infants Experiencing Minor Malformations

    Minor malformations not previously reported.

    Measured: Up through the first 12 months of life

  11. Percentage of Infants With Age-appropriate Infant Growth and Development

    Age-appropriate progress on developmental milestones based on the overall assessment by the infant's HCP (e.g., appropriate or delayed) up to 1 year of age.

    Measured: Up through the first 12 months of life
