Currently Recruiting Clinical Trials/Studies For Propionic Acidemia

NIH Natural History, Physiology, Microbiome and Biochemistry Studies of Propionic Acidemia

This study will evaluate patients with propionic acidemia to learn more about the genetic and biochemical causes and the medical complications associated with it.  They also plan to study how bacteria living in our gut (microbiome) can affect the course of propionic acidemia.

Open Label Study of mRNA-3927 in Patients With Propionic Acidemia

This is a Phase 1/2 study sponsored by Moderna TX, Inc.  It is designed to evaluate if an investigational treatment called mRNA-3927 is safe and effective in reducing the symptoms of PA in individuals one year of age and older.  mRNA 3927 is an investigational intravenous (IV) infusion treatment that instructs a persons’ body to make a PCC enzyme that works.
