2001 NOV 14 - (NewsRx.com & NewsRx.net) -- Genzyme Molecular Oncology (GZMO) has been issued a U.S. patent for the discovery of novel synthetic peptides and pharmaceutical compositions useful as therapeutic melanoma vaccines.
Discovered by Genzyme's antigen discovery group led by Charles A. Nicolette, PhD, the peptide ligands are superior immunogens when compared with the native gp100 epitope. The newly issued melanoma antigen patent provides synthetic peptide ligand variants of the 209 T-cell epitope of gp100 that may be useful in developing potent melanoma vaccines.
"Issuance of this patent is a key milestone for Genzyme Molecular Oncology," said Gail Maderis, president of Genzyme Molecular Oncology. "It is our first patent to issue on SPHERE peptides and demonstrates the ability of our SPHERE technology to identify novel, patentably distinct molecules, even in widely studied genes such as gp100. Furthermore, it comes at a fitting time as we prepare to initiate our first SPHERE peptide clinical trial in melanoma next year."
