Clinical Trials

DISCOVER CLINICAL STUDIES ON CDG

There are several ongoing clinical trials for CDG, with some trials actively recruiting participants. These studies vary from investigating specific CDG types to all CDG types and include both clinical trials to evaluate new potential therapies and observational studies such as natural history studies.

  • CDG Type(s): PMM2-CDG
  • Study Type: Clinical Trial, Phase II/III
  • Location: United States, Multi-Centre
  • Status: Recruiting

Mayo Clinic, in collaboration with Seattle Children’s Hospital and Children’s Hospital of Philadelphia, is conducting an interventional, randomized, double-blind, placebo-controlled study on PMM2-CDG. The purpose of this study is to assess efficacy of acetazolamide treatment of improving ataxia in PMM2-CDG patients, while monitoring adverse reactions, effects on biomarkers and characteristics of patients who do not respond to acetazolamide treatment.

  • CDG Type(s): All CDG Types
  • Study Type: Observational
  • Location: United States, Multi-Centre
  • Status: Recruiting

The Frontiers in CDG Consortium is conducting a multi-site 5-year natural history study on CDG.  The purpose of this study is to define the natural history and clinical symptoms of CDG, develop new diagnostic techniques, identify clinical biomarkers that can be used in future clinical trials and evaluate whether dietary treatments improve clinical symptoms and quality of life in CDG patients.
