An Observational Study of the Use and Safety of Xolair® During Pregnancy

The Xolair® Pregnancy Registry is an observational study established by Genentech to obtain data on pregnancy outcomes in women who are exposed to Xolair®. Women exposed to at least one dose of Xolair® within 8 weeks prior to conception or at any time during their pregnancy will be followed to completion of their pregnancies. The evaluation of infants will be conducted at birth and at 6-month intervals until the infants are 12 months old. Follow-up of the infant will be extended until the infant is 18 months old, if the woman continues Xolair® treatment while breastfeeding.
