A CAR-T-cell therapy known as axicabtagene ciloleucel (axi-cel) is safe and shows encouraging signs of efficacy in a small pilot trial involving patients with lymphoma of the brain and/or spinal cord, Dana-Farber Cancer Institute investigators report at the 64th American Society of Hematology (ASH) Annual Meeting.

The research features an in-depth, molecular study of individual CAR-T cells isolated from patients’ blood and cerebrospinal fluid (CSF), which surrounds the brain and spinal cord. This unprecedented analysis, conducted in collaboration with the Cellular Therapeutics and Systems Immunology Lab (CTSI), directed by Leslie Kean, MD, PhD, at Dana-Farber and Boston Children’s Hospital, reveals a surprising difference between the two CAR-T-cell populations: the cells in the CSF display a molecular signature that indicates activation of the interferon pathway, an important step in rallying the immune system. These studies are reported in two oral abstracts at ASH. “For many patients with lymphoma of the central nervous system, there aren’t great treatment options,” said Dana-Farber’s Caron Jacobson, MD, MMSc, who led the trial and will present the findings at ASH. “Our early results suggest that expanding the applicability of CAR-T cells to this indication could improve patient outcomes.”

Lymphomas can begin within the brain or spinal cord, or the tumors can spread to those sites (known collectively as the central nervous system or CNS) after they originate in other parts of the body. While the underlying biology of these primary and secondary CNS lymphomas can be quite different, these cancers are often difficult to treat, especially once the tumors evade standard treatments. In that case, patients typically do not live more than 2 years.

The study brings much hope to patients with brain and spinal cord cancers.

A small pilot trial involving patients with lymphoma of the brain and/or spinal cord has shown that CAR-T-cell therapy known as axicabtagene ciloleucel (axi-cel) can be a viable treatment option for patients who often have little hope, according to a press release by Dana-Farber Cancer Institute investigators published on Sunday. “For many patients with lymphoma of the central nervous system, there aren’t great treatment options,” said Dana-Farber’s Caron Jacobson, MD, MMSc, who led the trial.

Our early results suggest that expanding the applicability of CAR-T cells to this indication could improve patient outcomes.

Lymphomas typically feature aggressive tumors that can spread to the brain and spinal cord after they originate in other parts of the body. These cancers are often difficult to treat and patients do not survive more than two years.

The fight against Alzheimer’s disease has been a tough one, but we are making progress. Not only have scientists created tech that can detect Alzheimer’s in a single brain scan, but some research has also shown that repurposable drugs could help find a cure.
