AVROBIO Receives Orphan Drug Designation from the European Medicines Agency for AVR-RD-02, an Investigational Gene Therapy for Gaucher Disease – Yahoo…

By daniellenierenberg

AVROBIO, Inc. (Nasdaq: AVRO), a leading clinical-stage gene therapy company with a mission to free people from a lifetime of genetic disease, today announced that the European Commission (EC) has granted orphan drug designation for AVR-RD-02, the companys investigational gene therapy for the treatment of Gaucher disease. AVR-RD-02 consists of the patients own hematopoietic stem cells, genetically modified to express glucocerebrosidase (GCase), the enzyme that is deficient in Gaucher disease. AVROBIO recently dosed the first patient in the GuardOne Phase 1/2 clinical trial to evaluate the safety and efficacy of AVR-RD-02.

"Like many lysosomal disorders, Gaucher disease can lead to debilitating complications throughout the body and brain. The standard of care does not address all these symptoms and may not be able to halt progression of the disease," said Geoff MacKay, AVROBIOs president and CEO. "Our investigational gene therapy is designed to address the head-to-toe manifestations of Gaucher disease with a single dose. Were pleased to receive orphan drug designation, which recognizes the potential of our approach to transform the standard of care and, we hope, the quality of life for people living with this rare genetic disorder."

The EC grants orphan drug designation to drugs and biologics intended for the safe and effective treatment, diagnosis or prevention of rare diseases or conditions that impact fewer than 5 in 10,000 patients in the European Union. Orphan drug designation gives companies certain benefits, including reduced regulatory fees, clinical protocol assistance, research grants and 10 years of market exclusivity following regulatory approval.

AVR-RD-02 has also received orphan drug designation from the U.S. Food and Drug Administration.

About Gaucher Disease

Gaucher disease is a rare, inherited lysosomal storage disorder characterized by the toxic accumulation of glucosylceramide (GlcCer) and glucosylsphingosine (GlcSph) in macrophages. Macrophages bloated with these fatty substances are called Gaucher cells which amass primarily in the spleen, liver and bone marrow. This results in a variety of potential symptoms, including grossly enlarged liver and spleen, bone issues, fatigue, low hemoglobin levels and platelet counts and an adjusted lifetime relative risk of developing Parkinson's disease that may be more than 20 times greater than the general population. Even on enzyme replacement therapy (ERT) the current standard of care people with Gaucher disease type 1 typically have a shortened life expectancy and may experience debilitating symptoms that significantly reduce their quality of life. An estimated 1 in 44,000 people are diagnosed with Gaucher disease.

About AVR-RD-02

AVR-RD-02 is an investigational lentiviral gene therapy designed to provide a durable therapeutic benefit for people living with Gaucher disease. The therapy starts with the patients own hematopoietic stem cells, which are genetically modified to express functional glucocerebrosidase (GCase). Functional GCase reduces levels of glucosylceramide and glucosylsphingosine, the accumulated substances which cause the symptoms of Gaucher disease. AVROBIO is currently evaluating AVR-RD-02 in GuardOne, a Phase 1/2 clinical trial.

About lentiviral gene therapy

Lentiviral vectors are differentiated from other delivery mechanisms because of their large cargo capacity and their ability to integrate the therapeutic gene directly into the patients chromosomes. This integration is designed to maintain the therapeutic genes presence as the patients cells divide, which potentially enables dosing of pediatric patients, whose cells divide rapidly as they grow. Because the therapeutic gene is integrated into the patients own stem cells, patients are not excluded from receiving the investigational therapy due to pre-existing antibodies to the vector.

About AVROBIO

Our vision is to bring personalized gene therapy to the world. We aim to halt or reverse disease throughout the body by driving durable expression of functional protein, even in hard-to-reach tissues and organs including the brain, muscle and bone. Our clinical-stage programs include Fabry disease, Gaucher disease and cystinosis and we also are advancing a preclinical program in Pompe disease. AVROBIO is powered by the plato gene therapy platform, our foundation designed to scale gene therapy worldwide. We are headquartered in Cambridge, Mass., with an office in Toronto, Ontario.
