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.

Insight Study – HemoShear is now recruiting participants for the MMA and PA Insight Study. The study will evaluate how different assessments can measure verbal communication, processing speed, life skills, quality of life and sleep. The study is conducted virtually – no clinic visits are required.

  • Boston Children’s Hospital
  • Children’s Hospital of Pittsburgh
  • Children’s National Health System
  • Children’s Mercy in Kansas City
  • University of Minnesota

They will soon be recruiting at:

  • Rady Children’s Hospital (UC San Diego)
  • University of Florida
  • University of Utah
  • Vanderbilt University
  • Yale (in the fall)



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

The Paramount Study is a Phase 1/2 study.  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.

Study on BBP-671

CoA Therapeutics has completed the necessary preclinical studies in animals with their small molecule drug candidate, BBP-671, to support beginning human trials. Additionally, the U.S. Federal Drug Association (FDA) has approved their Investigational New Drug (IND) application to study BBP-671 in humans. In April 2021, they started a Phase 1 study to assess the safety of the drug in healthy volunteers before it is studied in PA and MMA patients. They plan to begin PA and MMA patient trials once we know that the drug candidate is safe, and have identified a dose appropriate for PA and MMA patients.
