AMSTERDAM, Netherlands, July 15, 2022 / B3C newswire / -- Polpharma Biologics, an international biotech company dedicated to the development of biosimilars, announced today that the European Medicines Agency (EMA) has accepted the first-ever Marketing Authorization Application (MAA) for biosimilar natalizumab, a proposed biosimilar to Tysabri®*. The application is for an intravenous (IV) route of administration, with the same dosing regimen, presentation and indication as the reference medicine Tysabri® - a single disease-modifying therapy (DMT) in adults with highly active relapsing-remitting multiple sclerosis (RRMS).1

Multiple sclerosis (MS) is a chronic inflammatory and neurodegenerative disease that can take a heavy toll on the quality of life of those affected. Up to half of all patients need to withdraw from employment within a decade of their diagnosis, need assistive walking devices within 15 years and are unable to walk 25 years after diagnosis.2  Due to the high cost of therapies, the economic burden of MS is substantial - between €37,000-57,000 per patient, per year in those with moderate-to-severe disease.3

The MAA submission was supported by a robust analytical, preclinical and clinical data package, including evidence from the Phase III Antelope study in RRMS patients.4  The Antelope study, plus an earlier Phase I trial, both met their primary endpoints, demonstrating that the proposed biosimilar matched the efficacy and safety of the reference medicine.

Biosimilar natalizumab was developed by scientists at Polpharma Biologics and the company retains responsibility for the manufacturing and supply of the medicine. Sandoz has the rights to commercialize and distribute the proposed biosimilar under an exclusive global license, secured through a commercialization agreement signed between Polpharma Biologics and Sandoz in 2019.

“The acceptance of the filing of proposed biosimilar natalizumab by the European regulatory authorities means we are a critical step closer to getting this important medicine to the patients who need it the most. We are deeply proud of the dedication of our scientific teams to take biosimilar natalizumab from cell line and technical development, through clinical trials to registration - today’s milestone is testament to their achievements,” said Michael Soldan, CEO. “Natalizumab is the second proposed biosimilar from our pipeline following ranibizumab** to have been successfully filed in Europe in the past year, showing the strength and depth of our product portfolio.”

Polpharma Biologics is focused on developing biosimilar therapies to treat some of the world’s most impactful diseases across neurology, immunology and ophthalmology. The company has a robust pipeline containing more than six biosimilars in different stages of development.
