To treat late-onset Pompe disease
FDA APPROVED Nexviazyme, 2021/8/6, Enzyme replacement therapy product
Treatment of Pompe disease
Biologic License Application (BLA): 761194
Company: GENZYME CORP
https://www.fda.gov/news-events/press-announcements/fda-approves-new-treatment-pompe-diseaseFor Immediate Release:August 06, 2021
Today, the U.S. Food and Drug Administration approved Nexviazyme (avalglucosidase alfa-ngpt) for intravenous infusion to treat patients 1 year of age and older with late-onset Pompe disease.
Patients with Pompe disease have an enzyme deficiency that leads to the accumulation of a complex sugar, called glycogen, in skeletal and heart muscles, which cause muscle weakness and premature death from respiratory or heart failure. Normally, glycogen—the stored form of glucose—breaks down to release glucose into the bloodstream to be used as fuel for the cells.
“Pompe disease is a rare genetic disease that causes premature death and has a debilitating effect on people’s lives,” said Janet Maynard, M.D., deputy director of the Office of Rare Diseases, Pediatrics, Urologic and Reproductive Medicine in the FDA’s Center for Drug Evaluation and Research. “Today’s approval brings patients with Pompe disease another enzyme replacement therapy option for this rare disease. The FDA will continue to work with stakeholders to advance the development of additional new, effective and safe therapies for rare diseases, including Pompe disease.”
Nexviazyme, an enzyme replacement therapy, is an intravenous medication that helps reduce glycogen accumulation. The effectiveness of Nexviazyme for the treatment of Pompe disease was demonstrated in a study of 100 patients who were randomized to take Nexviazyme or another FDA-approved enzyme replacement therapy for Pompe disease. Treatment with Nexviazyme improved lung function similar to the improvement seen with the other therapy.
The most common side effects included headache, fatigue, diarrhea, nausea, joint pain (arthralgia), dizziness, muscle pain (myalgia), itching (pruritus), vomiting, difficulty breathing (dyspnea), skin redness (erythema), feeling of “pins and needles” (paresthesia) and skin welts (urticaria). Serious reactions included hypersensitivity reactions like anaphylaxis and infusion-associated reactions, including respiratory distress, chills and raised body temperature (pyrexia). Patients susceptible to fluid volume overload or with compromised cardiac or respiratory function may be at risk for serious acute cardiorespiratory failure.
The FDA granted this application Fast Track, Priority Review and Breakthrough Therapy designations. Nexviazyme also received an orphan drug designation, which provides incentives to assist and encourage the development of drugs for rare diseases. The FDA granted the approval of Nexviazyme to Genzyme Corporation.
NEW DRUG APPROVALS
FDA grants priority review for avalglucosidase alfa, a potential new therapy for Pompe disease
- The FDA decision date for avalglucosidase alfa, an investigational enzyme replacement therapy, is set for May 18, 2021
- Regulatory submission based on positive data from two trials in patients with late-onset and infantile-onset Pompe disease, respectively
- Avalglucosidase alfa received FDA Breakthrough Therapy and Fast Track designations for the treatment of people with Pompe Disease
- Pompe disease, a rare degenerative muscle disorder, affects approximately 3,500 people in the U.S.
- Milestone reinforces 20+year commitment to Pompe disease community
PARIS – November 18, 2020 – The U.S. Food and Drug Administration (FDA) has accepted for priority review the Biologics License Application (BLA) for avalglucosidase alfa for long-term enzyme replacement therapy for the treatment of patients with Pompe disease (acid α-glucosidase deficiency). The target action date for the FDA decision is May 18, 2021.
Avalglucosidase alfa is an investigational enzyme replacement therapy designed to improve the delivery of acid alpha-glucosidase (GAA) enzyme to muscle cells, and if approved, would offer a potential new standard of care for patients with Pompe disease.
In October, the European Medicines Agency accepted for review the Marketing Authorization Application for avalglucosidase alfa for long-term enzyme replacement therapy for the treatment of patients with Pompe disease. The Medicines and Healthcare Products Regulatory Agency in the UK has granted Promising Innovative Medicine designation for avalglucosidase alfa.
“The hallmarks of Pompe disease are the relentless and debilitating deterioration of the muscles, which causes decreased respiratory function and mobility,” said Karin Knobe, Head of Development for Rare Diseases and Rare Blood Disorders at Sanofi. “Avalglucosidase alfa is specifically designed to deliver more GAA enzyme into the lysosomes of the muscle cells. We have been greatly encouraged by positive clinical trial results in patients with late-onset and infantile-onset Pompe disease.”
Pompe disease is a rare, degenerative muscle disorder that can impact an individual’s ability to move and breathe. It affects an estimated 3,500 people in the U.S. and can manifest at any age from infancy to late adulthood.i
The BLA is based on positive data from two trials:
- Pivotal Phase 3, double-blind, global comparator-controlled trial (COMET), which evaluated the safety and efficacy of avalglucosidase alfa compared to alglucosidase alfa (standard of care) in patients with late-onset Pompe disease. Results from this trial were presented during a Sanofi-hosted virtual scientific session in June 2020 and in October 2020 at World Muscle Society and the American Association of Neuromuscular and Electrodiagnostic Medicine.
- The Phase 2 (mini-COMET) trial evaluated the safety and exploratory efficacy of avalglucosidase alfa in patients with infantile-onset Pompe disease previously treated with alglucosidase alfa. Results from this trial were presented at the WORLDSymposium, in February 2020.
Delivery of GAA to Clear Glycogen
Pompe disease is caused by a genetic deficiency or dysfunction of the lysosomal enzyme GAA, which results in build-up of complex sugars (glycogen) in muscle cells throughout the body. The accumulation of glycogen leads to irreversible damage to the muscles, including respiratory muscles and the diaphragm muscle supporting lung function, and other skeletal muscles that affect mobility.
To reduce the glycogen accumulation caused by Pompe disease, the GAA enzyme must be delivered into the lysosomes within muscle cells. Research led by Sanofi has focused on ways to enhance the delivery of GAA into the lysosomes of muscle cells by targeting the mannose-6-phosphate (M6P) receptor that plays a key role in the transport of GAA.
Avalglucosidase alfa is designed with approximately 15-fold increase in M6P content, compared to standard of care alglucosidase alfa, and aims to help improve cellular enzyme uptake and enhance glycogen clearance in target tissues.ii The clinical relevance of this difference has not been confirmed.
Avalglucosidase alfa is currently under clinical investigation and its safety and efficacy have not been evaluated by any regulatory authority worldwide.

Glenmark’s Enrollment Begins of First Patient in Phase II Vatelizumab (GBR 500) Trial in Relapsing Remitting Multiple Sclerosis
Enrollment Begins of First Patient in Phase II Vatelizumab Trial in Relapsing Remitting Multiple Sclerosis
Glenmark outlicensed Vatelizumab (GBR 500) to Sanofi for all indications in 2011
Mumbai – India, November 4, 2014: Glenmark announced today enrollment of the first patient in a multicenter Phase II clinical trial to evaluate Genzyme’s investigational infusion therapy vatelizumab in patients with relapsing remitting multiple sclerosis (RRMS). The trial, called EMPIRE, is designed to assess the efficacy of vatelizumab vs. placebo in RRMS patients. The safety, tolerability and pharmacokinetics of vatelizumab will also be assessed.
The mechanism of action of vatelizumab, which is developed in a collaboration between Glenmark Pharmaceuticals and Genzyme, is not yet fully understood. However, the researchers believe that it will be able to block VLA-2 on activated immune cells, which may enable the interference with collagen-binding in areas of inflammation, as well as leading to the reduction of inflammatory cascade associated with MS.
“We are excited about the commencement of this trial and are pleased with the continued progress of our partnership with Sanofi/Genzyme,” said the President of Biologics and Chief Scientific Officer of Glenmark Pharmaceuticals Ltd., Michael Buschle. EMPIRE, which will be conducted for 12 weeks, is a global phase 2a/2b double-blind, randomized, placebo-controlled study that will study the efficacy, safety, and dose-response of vatelizumab in 168 patients with active RRMS at55 sites in ten different countries.

Genzyme Announces Positive New Data from Two Phase 3 Studies for Oral Eliglustat Tartrate for Gaucher Disease
Eliglustat tartrate (USAN)
The randomized, double-blind, placebo-controlled study had a primary efficacy endpoint of improvement in spleen size in patients treated with eliglustat tartrate. Patients were stratified at baseline by spleen volume. In the study, a statistically significant improvement in spleen size was observed at nine months in patients treated with eliglustat tartrate compared with placebo. Spleen volume in patients treated with eliglustat tartrate decreased from baseline by a mean of 28 percent compared with a mean increase of two percent in placebo patients, for an absolute difference of 30 percent (p<0.0001).
Eliglustat tartate (Genz-112638)
What is Eliglustat?
- Eliglustat is a new investigational phase 3 compound from Genzyme Corporation that is being studied for type 1 Gaucher Disease.
- Eliglustat works as a substrate reduction therapy by reducing glucocerebroside. formation.
- This product is an oral agent (i.e. a pill) that is taken once or twice a day in contrast to an IV infusion for enzyme replacement therapy. Enzyme replacement therapy focuses on replenishing the enzyme that is deficient in Gaucher Disease and breaks down glucocerebroside that accumulates.
- The clinical trials for eliglustat tartate are sponsored by Genzyme Corporation.
