Filed under : News

VPRIV or Velaglucerase alfa for injection has received the U.S.FDA (Food and Drug Administration) nod for treating of rare inborn neurological disorder known as Gaucher disease.

The lately accepted therapy is known to replace the deficient enzyme, glucocerebrosidase typically noted in individuals having the most form of the disorder, Type 1 Gaucher disease.

The FDA agency stated that there was a dearth of an older type of replacement treatment for the disease. The safety and efficacy quotient of VPRIV was assessed in clinical studies that enrolled 82 individuals from age of four till elderly people having Type 1 Gaucher disease.

VPRIV created in the Shire Human Genetic Therapies company in Massachusetts has some prevalent associated side-effects like giddiness, abdominal, joint and back pains, weariness, allergic reactions, drawn out blood clotting and fever.

gaucher diseaseGaucher disease is an atypical heritable metabolic disorder affecting barely one in fifty thousand individuals wherein detrimental amounts of a fatty matter known as glucocerebroside accruement occurs in the bone marrow, liver, spleen, lungs and at times also in the brain.

Gaucher disease is of three forms, namely: type1, type2 and type3.

Type 1 Gaucher disease is the most prevalent form typified by easy bruising, anemia-induced exhaustion and squat blood platelet count. Such patients additionally have spleen and liver enlargement, skeletal conditions and at times, impaired kidney and lung functioning although there are no symptoms of brain being affected.

In Type 2 Gaucher disease, the spleen and liver swelling becomes noticeable by three months of age. Individuals have wide-ranging and advanced brain damage and generally face fatality by the time they are two years old.

In Type 3 Gaucher disease, there is inconsistent swelling in spleen and liver and symptoms of brain being affected like seizures eventually become perceptible.

All people affected by Gaucher disease have a dearth of glucocerebrosidase enzyme which takes part in the assimilation and re-cycling of glucocerebroside.

The accumulation of this fatty matter inside the cells impedes proper functioning of the organs and cells.

Gaucher disease is one of the many lipid storage conditions. Enzyme replacement therapy has been shown to be vastly beneficial to those people having type 1 and type 3 Gaucher disease. The treatment has been noted to reduce swelling in spleen and liver, lessen skeletal abnormalities and effectually reverse other signs of the condition, inclusive of anomalous blood count.

Bone marrow transplant procedure is used for replacement of harmed or obliterated blood-producing cells and is capable of reversing the non-neurological outcomes of type 1 Gaucher disease, however carrying elevated death rate because of flawed donor matching. This procedure has been swapped with enzyme replacement therapy. There is absence of any therapy for reversing the acute brain damage which could develop in individuals having type 2 and type 3 Gaucher disease. Enzyme replacement therapy has been quite useful in treating type 1 and majority of the type 3 sufferers of this disorder.
