CD47

The most promising cancer treatment to date will begin human trials in mid-2014.

CD47 is a kind of protein that is found on the surface of many cells in the body. It tells circulating immune cells called macrophages not to eat these cells. The body uses the CD47 protein to protect cells that should be protected and to help dispose of cells that are aged or diseased.

... nearly every kind of cancer cell has a large amount of CD47 on the cell surface. This protein signal protects the cancer against attack by the body's immune system. Stanford investigators have discovered if that they block the CD47 "don't-eat-me" signal through the use of anti-CD47 antibodies, macrophages will consume and destroy cancer cells. Deadly human cancers have been diminished or eliminated in animal models through the use of anti-CD47 antibody.

For the last year, many people have been working to make clinical trials possible. We are now hopeful that the first human clinical trials of anti-CD47 antibody will take place at Stanford in mid-2014, if all goes well. Clinical trials may also be done in the United Kingdom.

You might want to revisit that link from time to time.

As we get closer to clinical trials, we will start posting information about enrollments on this page.
