5 Companies Bringing Innovation to the Fabry Disease Treatment Market

03 Mar 5 Companies Bringing Innovation to the Fabry Disease Treatment Market

Fabry Disease also known as angiokeratoma corporis diffusum or alpha-galactosidase A deficiency, is an inherited disorder characterized by the buildup of globotriaosylceramide, a type of fat in the body’s cells and results in numerous disorders such as acroparesthesias (burning, tingling, or prickling sensation in extremities), angiokeratomas (small, dark spots on the skin), hypohidrosis (reduced perspiration), corneal opacity or corneal verticillata tinnitus and hearing loss. In severe cases the disease can lead to progressive kidney damage, stroke and cardiac arrest.

According to the National Institute of Health, an estimated 1 in 40,000 to 60,000 males are affected by this disorder. This disease is primarily caused by a mutation in the GLA gene, which hinders the breakdown of globotriaosylceramide, thereby causing their buildup in the cell lining of blood vessels of the skin, kidneys, heart and nervous system. The condition is inherited through an X-linked pattern.

The disease is diagnosed through genetic testing and new born screening. The treatment for this disease uses a multi-disciplinary treatment approach that targets abnormal substrate accumulation and aims to prevent organ damage. At present enzyme replacement therapy is the recommended course of treatment, in which synthetic enzyme created through recombinant DNA are administered intravenously. Fabrazyme by Sanofi (NASDAQ: SNY) Genzyme is the only is the FDA approved ERT treatment in the U.S.

According to a report by Grandview Research the global Fabry Disease treatment market is expected to reach USD 3.12 billion by 2025, growing at a CAGR of 9.6%. The growth in the market will be driven by introduction of novel therapies such as substrate reduction therapies, enzyme replacement and chaperone treatments. We take a look at few companies at the forefront of innovation in this area.
