Treatment & Management

 

There is currently no cure for Fabry disease, but there are treatment options that can help with symptom management, slow the progression of the disease and improve quality of life. In Australia there are three treatments approved by the TGA (Therapeutic Goods Administration) which are funded by the Federal Department of Health's Life Saving Drugs Program or LSDP. 

 

Enzyme Replacement Therapy 

 

Enzyme Replacement Therapy (ERT) is a medical treatment replacing an enzyme in patients in whom that particular enzyme is deficient or absent. In the case of Fabry disease, the enzyme that is deficient is called α‐galactosidase A (α‐Gal A) enzyme. Enzyme replacement therapy does not affect the underlying genetic defect, but increases the concentration of enzyme in which the patient is deficient. ERT implies life-long treatments with regular and frequent intravenous infusions of enzyme biweekly throughout the patient’s life. There are two Enzyme Replacement Therapy drugs subsidised through the Australian Government's Life Saving Drugs Program (LSDP) for the treatment of Fabry disease. The generic names for these drugs are agalsidase alfa and agalsidase beta. The trade names for these drugs are Replagal® and Fabrazyme®. ERT was approved in Australia for the treatment of Fabry disease in 2004 and should be considered in all patients with documented Fabry disease, of any age and either sex, who meet disease-specific criteria. 

The most recent clinical guidelines and criteria for the use of ERT in Australia can be read in detail here

Oral Chaperone Therapy


Migalastat is an oral monotherapy (tablet) for Fabry disease patients with genetic mutations that are amenable to this chaperone therapy. Many individuals with Fabry disease make some a-Gal A enzyme that is capable of degrading substrate. However, because of a genetic mutation, the produced enzyme is not effectively delivered to lysosomes to reduce GL-3.

As a monotherapy, migalastat is an oral, small molecule drug designed to bind to, and stabilize the a-Gal A that is made in the patient’s own cells, with the intention of enabling its trafficking to lysosomes (designed to act as a “pharmacological chaperone”). Once delivered to lysosomes, the a-Gal A enzyme can degrade the accumulated GL-3. This approach is designed for patients with amenable mutations that are capable of responding to oral migalastat as a monotherapy treatment on the basis of their genotype. It is thought that 35-50% of patients with Fabry have an amenable mutation. Migalastat Monotherapy was approved as a safe and effective therapy by the EMA (European Medicines Agency). From 1 November 2018, Galafold® (migalastat) will be listed on Australia’s Life Saving Drugs Program (LSDP) for the long-term treatment of patients 16 years and older with a confirmed diagnosis of Fabry disease, who have an amenable mutation.

The criteria for receiving funded Galafold® (migalastat) treatment via the Life Saving Drugs Program is on the Department of Health website link here

You can learn if your mutation is amenable by asking your Fabry specialist.

Emerging Therapies

Research is ongoing and new therapies are currently under development. To learn more about which clinical studies are  happening for Fabry disease go to www.clinicaltrials.gov  Please subscribe to our E Newsletter which lists latest information and ask your Fabry Clinic for further information.

Substrate Reduction Therapy

Substrate Reduction Therapy (SRT) uses an orally available, small molecule drug that inhibits the first committed step in glycosphingolipid biosynthesis. The objective of SRT is to curb the synthesis or production of substrate which is not degraded and therefore accumulates. Using this method, the synthesis of a particular molecule is decreased with the aim of creating a better balance between synthesis (controlling the production of substrate) and degradation (controlling how much needs to be degraded and stored).

 

Gene Therapy

 

Gene Therapy is a treatment approach that involves introducing genetic material into a person’s cells to fight or prevent the disease.  The first Fabry man to receive Gene Therapy in a Phase I clinical study was in 2017 in Canada. Studies are now being enrolled to do further investigation in a Phase II clinical study including Australia.

 

Clinical Trials for Fabry Disease

Did you know that there are 137 Fabry disease studies listed on the Clinical Trials website, 17 of these are in Australia?  Some are complete, some have recruited and some are recruiting. To learn more about which clinical studies are happening for Fabry disease go to ClinicalTrials.gov You can search by disease and check if any studies are happening in Australia. Remember - there may be a study not going on in your particular location, but you can still contact the study investigator to find out more about the research they are conducting.
