Before this therapy was approved T-cell therapy was only available through small clinical trial for people with advanced blood cancers. These trials had remarkable responses for adults and children whose other treatments failed. This got the attention of many researches who worked to get this therapy approved. Now children with acute lymphoblastic leukemia (ALL) and adults with advanced lymphomas have the option of gene therapy to stop the growth and spread of their cancerous cells1.
