The CRISPR–Cas9 gene editing technique has been in the news for several years now as researchers have been using it on test animals to test the possibility of safely using the technique on humans. Known as CRISPR-Cas9, this technology has led to a breakthrough in genomic engineering. But beyond the cancer study, researchers in Europe, the United States and Canada are launching at least half a dozen carefully designed studies aimed at using CRISPR to treat a variety of diseases. These studies are a first step toward fulfilling the gene editor’s medical promise CRISPR/Cas9 is a gene-editing tool that many hope will correct genetic diseases. This study is currently underway at the University of … The first CRISPR-based therapy trial in the US combines CAR-T and PD-1 immunotherapy approaches. From Bacteria to Breakthrough.
