First CRISPR trial in humans will attempt to battle lung cancer

The first human trial of cells that have been tweaked by the genome-editing technique CRISPR will begin in China in August, Nature reports. The group will take white blood cells, which are part of the immune system, from people with a type of lung cancer and edit them using the CRISPR technology so they hunt cancer. Then, the lab-altered cells will be infused back into the patients.

The approach is similar to another trial in the U.S., which will test edited immune cells in several kinds of cancer. Trials with modified white blood cells, called T cells, have been run before. But scientists haven't used the CRISPR technique to make the edits, relying instead on a virus to insert the sequences into the cells' DNA. CRISPR, which is...
