CRISPR, Clustered Regularly Interspaced Short Palindromic Repeats, the genome-editing technology may be used on a trial involving patients by the end of the year.
On June 21st, an advisory committee at the US National Institutes of Health (NIH) approved a proposal to use the CIRSPR-Cas9. CRISPR will be used to augment cancer therapies using the patients T cells, immune cells. Gene editing could improve treatments drastically.
The first trial has been designed to test the safety of the technology for us in people. The University of Pennsylvania will manufacture edited cells and treat patients with locations including California and Texas. An immunotherapy foundation will be funding the project.
There will be approximately 18 patients who will have their T cells removed. 3 CIRSPR edits will be performed: The first edit will insert a gene for an engineered protein capable of detecting cancer cells and instructing T cells to target them, the second edit removes a T-cell protein that may interfere in the process, and the third edit will remove the gene for a protein which identifies the T cells as immune cells and prevents them from being disabled by the cancer cells. The last part of the process will be to infuse the edited cells back into the patient.
With the approval coming from NIH all that’s needed to successfully being trials is the permissions from US regulators and review boards. Though if approved trials could begin by the end of the year.
