Founded in 2014 and based in Los Angeles, California, Pregistry addresses the lack of safety and efficacy information for prescription medications and vaccines used during pregnancy. With close to 4.5 million pregnant women using these products each year in the US, Pregistry partners with pharmaceutical companies to fulfill regulatory requirements and provide pregnant women, nursing mothers, and healthcare providers with the necessary information to safely treat medical conditions. In November 2022, Pregistry was acquired by CorEvitas, a company with 20 years of experience in patient registries and curated data sources, further advancing comparative effectiveness research and drug safety studies.
