5. Study Description

Brief Summary
This First-in-Human (FIH) Phase 1/2 study will evaluate the safety and pharmacological activity of mRNA-3927 in participants 1 year of age and older with genetically confirmed propionic acidemia (PA). The study is designed to characterize baseline biomarker levels followed by assessment of safety, pharmacokinetics (PK), and pharmacodynamics (PD) of different doses of mRNA-3927 in participants affected by PA as part of the Dose Optimization phase.
Detailed Description
During the Dose Optimization Stage, after each dose cohort is fully enrolled, and the dose-limiting toxicity (DLT) observation window of at least 14 days is complete for the final participant in that cohort, the Sponsor will review the totality of available safety data in conjunction with all available PK/PD data. Based on this review, the Sponsor will recommend a revised dose and/or dosing interval. The Sponsor will abide by predefined constraints as to the maximum percentage change in dose and dose interval. A maximum of 6 cohorts will be enrolled into the study. Upon establishment of a dose with acceptable safety and pharmacodynamic activity, additional participants will be enrolled in a Dose Expansion Stage to allow for further characterization of the safety and pharmacodynamics of mRNA-3927. Participants in both phases of study will participate in a predosing observational period, followed by a treatment period, and then a follow-up period after withdrawal of treatment.
