NED Biosystems Inc., a Cambridge, Mass.-based venture developing a seven-agent combination therapy for cancer, has secured a U.S. patent for the treatment, called NED-170. The oral regimen, which comes in a daily seven-pill pack, targets both angiogenic and immune response pathways for the potential treatment of several types of cancers. If successful, it could potentially help not only extend lives, but also drive down the costs of cancer care in certain cases.
