New York: Stanford researchers are on track to begin human trials of a potentially potent new drug against cancer by next year, it has been revealed.The progress comes just two months after the groundbreaking study by Dr Irv Weissman, who developed an antibody that breaks down a cancer`s defense mechanisms in the body, the New York Post reported.A protein called CD47 tells the body not to "eat" the cancer, but the antibody developed by Dr Weissman blocks CD47 and frees up immune cells called macrophages - which can then engulf the deadly cells.
