NIH Intramural Research Program's Pregnancy Registry Protocol for Subjects and Their Partners

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: In 2018, the NIH intramural research program had almost 23,000 people taking part in active clinical research studies. Half of those people were female. More than a third were of child-bearing age. Researchers want to use data from this group to create a pregnancy registry. It will be used to collect data about pregnancy and birth outcomes related to unplanned exposure to research products. These products may include drugs, vaccines, treatments, and interventions. Objective: To collect data about pregnancies and births from people who took part in an NIH clinical trial and their partners who became pregnant while in the study or shortly after. Eligibility: People of any age and their partners who took part in an NIH clinical trial and became pregnant while in the study or within 1 year after. Design: Participants will be screened by phone. Their clinical trial history will be verified. Participants will be interviewed in person, by phone, or virtually. They will be asked about their health and their trial experience in relation to their pregnancy. They will give details about their pregnancy and baby (if appliable). They will be interviewed every 6 months for 1 year after the birth of their baby, as applicable. Data from both NIH and outside medical records will be used. Participants will give their doctor s name and contact details. They will provide a release for their records to be used. If needed, they will provide a release for their baby s records. Data will be coded and stored in a database on an in-house NIH secure server. Data may be used in future studies
