Frexalimab, in development by Sanofi, is a first-in-class, second generation anti-CD40 ligand monoclonal antibody.

Worldwide sales of MS therapies amounted to approximately $25 billion in 2023 according to IQVIA.
Pablo Legorreta, Royalty Pharma's founder and Chief Executive Officer said, "This transaction will expand our attractive and growing development-stage portfolio with a next-generation immunology therapy.
