Sandoz and Polpharma Biologics are celebrating the second major regulatory nod for their biosimilar rival to Biogen’s Tysabri (natalizumab), after the pair’s partnered Tyruko (natalizumab-sztn) version received US Food and Drug Administration approval.
Developed by Polpharma Biologics, the biosimilar saw its global commercialization rights licensed to Sandoz under a 2019 deal.
