A Phase 1/2, Global, Open-Label, Extension Study to Evaluate the Long-Term Safety and Clinical Activity of mRNA-3927 in Participants Previously Enrolled in the mRNA-3927-P101 Study
ModernaTX, Inc.
Summary
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).
Description
The study will assess long-term safety of mRNA-3927. Participants with PA who were previously enrolled and completed the end-of-treatment (EOT)/early termination (ET) visit of the mRNA-3927-P101 study will have the option to enroll into this extension study provided all eligibility criteria have been met. The study will include 2 periods: 1) Treatment Period and 2) Follow-up Period (90 days after the EOT visit). All participants will enter the study receiving mRNA-3927 at the same dose and at the same dosing interval last received in the mRNA-3927-P101 study.
