No results posted yet for this study

Summary

This is a prospective, observational, exposure cohort study of pregnancy and infant outcomes in women with asthma exposed to benralizumab anytime during pregnancy, or within 8 weeks prior to the first day of the last menstrual period (LMP)

The objective of the study is to monitor planned or unplanned pregnancies to evaluate potential teratogenic effect (birth defect) when exposed to benralizumab compared to two unexposed comparator groups.

The primary outcome is major structural birth defects (abnormalities in development of structures of the body) and the secondary outcomes are preterm delivery (premature baby), small for gestational age infants (small for weight, length, and/or head circumference), spontaneous abortion (miscarriage), stillbirth (baby born without signs of life), elective termination (voluntary abortion) and small for age postnatal growth to one year of age (small for weight, length and/or head circumference). The birth prevalence or incidence of outcomes in women exposed to benralizumab, and their infants, will be compared to those observed in two unexposed comparator groups: a disease-matched comparison group of women who have not used benralizumab during pregnancy or within 8 weeks of their last menstrual period (LMP), but who have used other anti-asthmatic medications (treated disease comparison group), and a comparison group of healthy women who do not have a diagnosis of asthma, have not had exposure to a known human teratogen (substance that causes birth defect), and have not taken benralizumab in pregnancy (healthy comparison group).

Conditions

Interventions

DRUG

Benralizumab-exposure

Exposure is defined as any dose of benralizumab for any length of time from 8 weeks prior to Last Mentrual Period (LMP) through the end of pregnancy, as reported by the mother and validated through medical record review. The 8-week cut-off prior to LMP is based upon the terminal half-life of benralizumab of approximately 15 days (clearance of benralizumab is based on five half-lives).

DRUG

Exposure to other asthma medications

Exposure to asthma medications for any number of days, at any dose, and at any time from LMP up to the date of enrollment, but no exposure to benralizumab during pregnancy or within 8 weeks prior to LMP.
