Doctors have infused cells edited using CRISPR-Cas9 into two patients in a trial conducted at the University of Pennsylvania, NPR reports today (April 16). A university spokesperson confirmed in an emailed statement to The Scientist that the trial is underway and that two patients, one with multiple myeloma and one with sarcoma, have been treated so far. The study is the first instance of patients in the US being treated with a CRISPR-based therapy.
In an interview with The Scientist in June 2018, the leader of the study, oncologist Edward Stadtmauer, explained that CRISPR would be used as a tool in a new type of immunotherapy. His team would filter T cells from the blood of eligible patients with cancer, then use the gene-editing technique to knock out three of the cells’ existing receptors and with a lentiviral vector insert the gene for a receptor ...
