Clinical-stage oncology company Nuview Life Sciences Inc. is developing a cancer diagnostic test and treatment delivery system that could reduce the need for costly, less accurate tests and surgical biopsies. The binary – yes/no – test employs a proprietary peptide construct, NV-VPAC1, that targets a specific receptor, called vasoactive intestinal peptide receptor type 1 (VPAC1), that is overexpressed on the surface of cancer cells.
