Will Patient Deaths Derail the CAR-T Train in Autoimmune Disease?
Novartis, BMS reportedly halt trials; first serious blow to burgeoning field
When the actor Sam Neill died unexpectedly in July this year, media reports emphasized that his death was not due to cancer. Neill was diagnosed in 2022 with angioimmunoblastic T-cell lymphoma […] after four years in remission he stopped responding to chemotherapy. […] Neill seems to have responded well [to CAR-T], and in April 2026 he publicly announced that he was “cancer-free.” Yet only four months later he was dead, and many people were puzzled about what had “gone wrong.”
The health care of the future may see more and more patients in this ambivalent territory, in which they can be described as free of their original disease but because of their treatment are living in a state of chronic fragility. Yet in many cases there is still a cultural expectation that a “successful” treatment is one that restores the patient to a state of health, without the need of ongoing clinical management.
The rapidly expanding ability to manipulate the immune system pharmaceutically, increased automation, and the use of artificial intelligence promise to accelerate drug discovery and clinical trials. In this new era of therapeutic development, clarity about goals, outcomes, and realistic expectations is crucial. However successful it is against the primary condition, a therapy that leaves patients in need of continuing and possibly equally demanding health care is not only economically costly, but raises ethical questions about quality of life. Clinicians also need to be able to communicate clearly what “cure” or “disease-free” might mean in different contexts. This need will increase because—as has been the case with CAR T-cell therapy—when an innovative treatment receives regulatory approval and becomes standard care, its use tends to expand from the group of patients with no other treatment options to those in earlier disease stages, or with different diseases.
