US FDA eliminates risk evaluation, mitigation strategies for CAR-T cancer therapies

The cancer therapies include Bristol-Myers Squibb's Breyanzi and its partnered therapy Abecma with 2seventy bio , Johnson & Johnson's unit Janssen and Legend Biotech's Carvykti, Novartis AG's Kymriah, and Gilead Sciences' unit Kite's Tecartus and Yescarta.

Bristol-Myers Squibb and Gilead Sciences did not immediately respond to Reuters' requests for comment.

These are gene therapies that are currently approved to treat blood cancers, such as multiple myeloma and certain types of leukemia and lymphoma, the health regulator said.

CAR-T treatment generally involves extracting disease-fighting white blood cells known as T-cells from a patient, re-engineering them to attack cancer and infusing them back into the body.

In January 2024, the FDA asked several drugmakers to add a serious warning on the label of their cancer therapies that use CAR-T technology after reports of T-cell malignancies and adverse events identified since approval.

The FDA earlier said the risk of T-cell malignancies including leukemia and lymphoma applies to all therapies in the class and can lead to hospitalization and death.
