How Galafold (migalastat) works

Galafold (migalastat) is a pharmacologic chaperone. It attaches to a protein in your body called alpha-galactosidase A (alpha-Gal A), which doesn’t work as well as it should in Fabry disease. By attaching to alpha-Gal A, Galafold (migalastat) helps the protein travel to where it needs to go to break down extra fatty waste in the body.

Frequently asked questions about Galafold (migalastat)

What is Fabry disease?

Fabry disease is a rare, inherited condition caused by changes in the GLA gene. The GLA gene provides instructions for your body on how to make a protein called alpha-Gal A. Alpha-Gal A helps get rid of certain fats from your body. People with Fabry disease often don't have much alpha-Gal A that function correctly. As a result, the fats start to collect in blood vessels, the kidneys, the heart, and many other organs. Extra fats can cause nerve pain; nausea and vomiting; small, red spots on the skin; and hearing loss. Over time, they can also cause serious problems, such as kidney failure, irregular heartbeat, and stroke. Everyone can have different signs and symptoms of this condition. If you have Fabry disease, it's important to follow up with a provider often, even if you don't have any signs and symptoms.

What is the FDA’s Accelerated Approval Program?

The FDA's Accelerated Approval Program allows a new medication to be approved faster than usual if it fulfills an unmet need or if it treats serious or life-threatening conditions. These approvals are based on lab measurements that are thought to predict health outcomes before the medication shows clear benefits. For Galafold (migalastat), the medication lowered the amount of extra fats in the kidneys, which can potentially predict better survival chance in people with Fabry disease. After accelerated approval, the manufacturer is required to complete clinical studies to confirm beneficial health outcomes (in this case, if Galafold (migalastat) improved health outcomes in people with Fabry disease). Depending on the results of these studies, the FDA can either give the medication a full approval or pull it off the market.
