ALT-B4
ALT-B4 (berahyaluronidase alfa) is a proprietary recombinant human hyaluronidase developed using Alteogen’s Hybrozyme™ platform technology. ALT-B4 enables the conversion of biologics typically administered via intravenous (IV) infusion into more convenient and rapid subcutaneous (SC) formulations. By temporarily depolymerizing hyaluronan in the extracellular matrix, ALT-B4 facilitates the rapid and efficient dispersion and absorption of co-administered therapeutics.
