Fabry clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Diagnostic Value of the Electrocardiogram in Fabry Disease

DEFY

Start date: March 2018
Phase: N/A
Study type: Observational

Cardiac complications occur in 78% of patients with Fabry disease and are mainly characterized by a high frequency of left ventricular hypertrophy resulting from an accumulation of GL3 in cardiomyocytes. Apart from family screening, left ventricular hypertrophy is an important factor in the diagnosis of Fabry disease. This left ventricular hypertrophy is more often concentric and homogeneous, but it can also be asymmetric and mimic the patterns seen in so-called familial hypertrophic cardiomyopathies caused by mutations in the sarcomere protein genes. Electrocardiogram has been suggested as a screening tool for Fabry disease. Analysis of the PQ interval would be of interest. An algorithm has even been proposed to differentiate Fabry disease from amyloidosis with excellent sensitivity and specificity. The only criterion of left ventricular hypertrophy used in all studies is the Sokolov-Lyon index, but this index has many limitations and does not appear to be discriminatory for Fabry disease. Other validated criteria for left ventricular hypertrophy, such as the Cornell, Lewis, Gubner index or the Romhilt-Estes point score, have never been tested in Fabry disease. The primary objective of our study is to evaluate the diagnostic value of different electrocardiographic scores of left ventricular hypertrophy in Fabry disease.
