New Drug That Kills Cancer Tumors Ready for Trials

After more than a decade of research, Stanford University biologist Irving Weissman told Science Magazine that his tumor-killing drug is ready for human trials.


Weissman said numerous tests have shown that his experimental drug either killed or shrank the cancerous growths implanted into mice.


His drug was tested on a variety of different cancers, including bladder, brain, liver, breast, colon, ovary and prostate growths. In all cases, it succeeded in reduction or total elimination of the cancer.


Weissman said his drug works by tricking cancer cells into shutting down production of a specific protein that camouflages the disease from the host’s immune system. The CD47 protein was discovered in blood cancers, but research has found that it also exists in virtually every other type of human cancer as well.
