This LTFU is being conducted to assess long-term safety and durability of response in participants dosed with IP in a parent protocol, and to collect longitudinal natural history in enrolled but not dosed participants who also participated in a parent protocol.

This research study is exploring the use of genomic sequencing in the newborn period to screen healthy babies for current and future health risks. The study will enroll a diverse cohort of 500 healthy infants and their parents from Boston, MA; New York City, NY; and...

The main purpose of this study is to evaluate the long-term safety of mRNA-3927 administered to participants with propionic acidemia (PA) who have previously participated in Study mRNA-3927-P101 (NCT04159103).

This 3-part, Phase 1/2 study is designed to characterize the safety, tolerability, and pharmacological activity (as assessed by biomarker measurements) and to determine the selected dose of mRNA-3927 in participants with genetically confirmed propionic acidemia (PA)....
