The Sponsor has made a decision, driven by business needs, to cease promotion, manufacturing, distribution and sales of Amevive

This is an observational, exposure-registration and follow-up study, to be conducted in the United States (US). The AMEVIVE® Pregnancy Exposure Registry is designed to monitor pregnant subjects and fetuses exposed to AMEVIVE® in order to detect any potential increase in the risk of major birth defects.

The AMEVIVE® Pregnancy Exposure Registry is sponsored by Astellas Pharma Global Development and will be managed by INC Research. The Registry will be monitored by an independent Advisory Committee of external experts in relevant specialties of teratology, epidemiology, maternal and fetal medicine, and infectious disease medicine (external member details available upon request).

Prospective reports will be collected from pregnant subjects, health care provider (HCP), or Astellas Product Safety Management staff. Data from the pregnant subjects will be collected at 4 to 5 months of pregnancy by telephone interviews with the Registry. The Registry will also contact the subject at 2 months and 12 months after the estimated delivery date (EDD) for post-natal & pediatric follow-up. The Registry will confirm the information collected from the subject with the HCP by telephone interviews with the Registry, forms mailed/faxed to the Registry, electronic forms/queries sent to the Registry, or a combination of these methods. If a live birth is reported, the infant's HCP will be contacted for the Pediatric Follow-Up at 2 months and 12 months of age. If a birth defect is reported, targeted follow-up will be conducted.
