New Enzyme Replacement Therapy Announced in Malaysia to Treat Pompe Disease

WORDS LIM TECK CHOON

Sanofi Malaysia announced this month that Nexviazyme® (avalglucosidase alfa), a new enzyme replacement therapy (ERT), has been approved in Malaysia for the treatment of Pompe disease, a rare and progressive genetic disorder that is often fatal if left untreated.

A QUICK PRIMER ON POMPE DISEASE
  • It is caused by a deficiency in acid glucosidase (GAA).
  • This deficiency causes an accumulation of a substance called lysosomal glycogen in the body’s tissues. This primarily affects the muscles.
  • As a result, the affected person will experience symptoms like muscle weakness, breathing difficulties, and heart problems. They may require the use of wheelchairs and respiratory support.
  • Pompe disease can affect individuals of all ages, but it is broadly divided into infantile onset Pompe disease (IOPD) and late onset Pompe disease (LOPD).
BENEFITS OF NEXVIAZYME® 
  • It can improve the lung function and walking distance of people living with Pompe disease.
  • There is also evidence that it can also help improve their muscle strength.
  • Certain clinical studies indicated that people with infantile onset Pompe disease exhibited improved motor functions, despite showing suboptimal response to previous treatments.
  • Other clinical studies found that those with late onset Pompe disease exhibited improved function of their respiratory muscles and increased ability to walk farther.

Nexviazyme® is approved for use in long-term enzyme replacement therapy, delivered via a drip or intravenously every 2 weeks.
