Alteogen and Novartis Sign $3.2 Billion Option and License Agreement for ALT-B4 (Berahyaluronidase Alfa) Subcutaneous-Conversion Platform
Alteogen (KOSDAQ: 196170) announced Wednesday September 2, 2026 an option and license agreement with Novartis (NYSE: NVS) for the development and commercialization of subcutaneous formulations of multiple Novartis products using Alteogen's ALT-B4 (berahyaluronidase alfa) enabled by the proprietary Hybrozyme technology. Terms: up to $3.22 billion in aggregate potential value including option exercise fees, development and commercial milestone payments, plus royalties on net sales. ALT-B4 temporarily depolymerizes hyaluronan in the extracellular matrix, enabling co-administered biologics to disperse and absorb subcutaneously rather than requiring intravenous infusion. The transaction is Alteogen's fourth Hybrozyme deal in 2026 following prior agreements with Merck KGaA, Sanofi, and one undisclosed global pharma. The technology approach mirrors Halozyme Therapeutics's ENHANZE platform (used in Roche's SC Herceptin, Rituxan, and Ocrevus, plus Bristol Myers Squibb's SC Opdivo and Johnson & Johnson's SC Darzalex), and the SC-conversion category has become an anchor commercial strategy for pharma companies looking to extend patent life and improve patient convenience on established IV biologics.
