Sanofi SNY announced that the European Commission granted marketing approval to two new enzyme replacement therapies, Nexviadyme (avalglucosidase alfa) and Xenpozyme (olipudase alfa).

Nexviadyme, an enzyme replacement therapy, is approved for the treatment of Pompe disease, a rare degenerative muscle disorder.  Nexviadyme is approved for both late-onset Pompe disease and infantile-onset Pompe disease and is the first new drug approved for Pompe disease in Europe in more than 15 years. The last Pompe disease drug approved in Europe was Sanofi’s drug, Myozyme.

Avalglucosidase alfa was approved in the United States in August 2021 in the name of Nexviazyme. Nexviazyme recorded sales of €30 million in the first quarter of 2022. Nexviazyme is also approved in Japan, Canada, Switzerland, Australia, Brazil, Taiwan and the United Arab Emirates.

Sanofi’s stock has risen 5% this year so far compared with the industry’s increase of 5.9%.

Nexviadyme’s approval was based on data from two pivotal studies, which include both infantile-onset and late-onset Pompe disease patients.

Pompe disease causes a debilitating deterioration of the muscles resulting in decreased respiratory function and mobility in affected patients. Nexviazyme targets the M6P receptor, the key pathway for cellular uptake of enzyme replacement therapy. In a phase III study called COMET, Nexviazyme resulted in improvements in respiratory function and walking distance in patients with LOPD.

In November 2022, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency recommended approving avalglucosidase alfa. However, the CHMP considered that avalglucosidase alfa does not qualify as a New Active Substance (“NAS”), which means a substance not previously authorized as a medicinal product in the EU. In April 2022, the Committee for Orphan Medicinal Product (COMP) also recommended the removal of Nexviadyme from the Community Register of Orphan Medicinal Products (OMP).

In a separate press release, Sanofi announced that Xenpozyme (olipudase alfa) was approved for the treatment of adult and pediatric patients with non-Central Nervous System (CNS) manifestations of acid sphingomyelinase deficiency (ASMD), a rare, progressive, and potentially life-threatening genetic disease in Europe. It is the first and only disease-specific therapy for ASMD in Europe.

Xenpozyme is already approved in Japan for ASMD. An application seeing approval for olipudase alfa is under review in the United States, with a decision expected next week

Xenpozyme’s approval was based on data from two clinical studies, in which Xenpozyme led to robust and clinically relevant improvement in lung function and reduced spleen and liver volumes. Enlarged spleen or liver, difficulty in breathing, lung infections, and unusual bruising or bleeding are some of the signs and symptoms of this rare disease, which particularly affects infants and children and is associated with substantial morbidity and risk of premature death.

Nexviadyme, on approval, could face potential competition from Amicus Therapeutics’ FOLD AT-GAA for the treatment of Pompe disease. The candidate consists of two components — cipaglucosidase alfa — an engineered enzyme to enhance lysosomal uptake into cells and miglustat, a stabilizer of the engineered enzyme. The FDA has accepted Amicus Therapeutics’ two regulatory filings for AT-GAA — a biologics license application (BLA) for cipaglucosidase alfa and a new drug application (NDA) for miglustat – for Pompe disease. The FDA has set PDUFA action dates of Aug 29, 2022 for the NDA and Oct 29, 2022 for the BLA. Amicus Therapeutics’ marketing authorization application submissions for AT-GAA with the European Medicines Agency were filed and validated in the fourth quarter of 2021.
