Recruiting PHASE1, PHASE2 Propionic Acidemia

New treatment option for Propionic Acidemia

Official title Open-Label Study of mRNA-3927 in Participants With Propionic Acidemia

ClinicalTrials.gov ID: NCT04159103

What this study is testing

What is mRNA-3927?

mRNA-3927 is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for propionic acidemia.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
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). After establishing a dose with an acceptable safety and pharmacodynamic (PD) response for participants ≥1 year of age in Part 1, participants will be enrolled in Part 2 (which will serve as the pivotal study) to allow for determination of the efficacy, safety, and PD of mRNA-3927.
